"As early as 1841, the Government began to profit by his experience, the Lords of the Admiralty having in that year consulted him on the subject of floating fire-engines for the various dockyards. These were eventually constructed from his designs and under his superintendence. In the following year he inspected all the dockyards, and reported fully on each, with regard to both floating and land fire-engines, the supply of water, the alterations of buildings to prevent spread of fire, and the proper care required in dangerous trades. From this time, although not holding any appointment, he acted as Government consulting engineer on all questions relating to fire prevention and extinction, and he advised from time to time the precautions to be taken for the protection of the royal palaces and various other public buildings. This position enabled him, not without a great deal of opposition, to induce the Government to adopt in all its departments a uniform size of hose-coupling. This is the one which he introduced in Edinburgh, and known as the London Fire Brigade coupling, is now in almost universal use; its application has been found comparatively of as much utility for fire-brigade purposes, as the adoption of the Whitworth gauges of screw-bolts for mechanical engineering."Although so fully occupied, he never refused advice on professional matters to all who sought it. The various dock companies, public institutions, country fire brigades, private firms, &c., benefited largely by his experience. The numerous inquiries from foreign countries and the colonies with regard to the best means of extinguishing fires, alsomade great inroads on his time. In 1833 he became an Associate of the Institution of Civil Engineers, to which, in 1844, he contributed a valuable paper 'On the means of rendering large supplies of Water available in case of Fire, &c.,' for which he was awarded a Telford Medal; and in 1849 a second paper 'On Fire-Proof Buildings.' In 1856, a paper on 'Fires: the best means of preventing and arresting them; with a few words on Fire-Proof Structures,' was read by him before the Society of Arts."He took great interest in the passing of Acts of Parliament for regulating buildings in the metropolis, was consulted by the framers of these Acts, and used his utmost influence to prevent the endangering a whole neighbourhood by the erection of monster warehouses for private profit. He strongly contended for the principle of dividing buildings by party-walls carried through the roof, and restricting these divisions to a moderate cubic content. Writing to Lord Seymour, Commissioner of Woods and Forests, on the 28th June, 1851, he said 'that no preparations for contending with such fires will give anything like the security that judicious arrangements in the size and construction of buildings will do.' The wise provisions introduced through his instrumentality into these Acts of Parliament were continually being evaded, and clusters of warehouses quickly rose which he saw would, if on fire, defy all his means of extinction. In a letter to Sir W. Molesworth, First Commissioner of Public Works, dated 10th February, 1854, on the subject of a proposed warehouse in Tooley-street, he wrote 'The whole building, if once fairly on fire in one floor, will become such a mass of fire that there is now no power in London capable of extinguishing it, or even ofrestraining its ravages on every side, and on three sides it will be surrounded by property of immense value.' How literally this was realized, and at what cost, was shown by the great warehouse fire in Tooley-street, on the 22nd June, 1861, at which Mr. Braidwood lost his life."

How literally this was realized, and at what cost, was shown by the great warehouse fire in Tooley-street, on the 22nd June, 1861, at which Mr. Braidwood lost his life."
The great fire at Cotton's Wharf; Tooley-street, broke out on Saturday, June 22nd, 1861, and continued to burn for more than a fortnight, consuming Scovell's, and other large warehouses, and, in all, upwards of two millions' worth of property. The fire is believed to have originated in the spontaneous combustion of hemp, of which upwards of 1000 tons were consumed, together with 3000 tons of sugar, 500 tons of saltpetre, nearly 5000 tons of rice, 18,000 bales of cotton, 10,000 casks of tallow, 1100 tons of jute, and an immense quantity of tea, spices, &c., besides many other descriptions of goods. Although discovered in broad daylight, and before the flames had made any considerable headway, the want of a ready supply of water, and the fact that the iron doors in the division walls between the several warehouses had been left open, taken in connexion with the extremely combustible nature of the materials, soon rendered hopeless all chance of saving the buildings and property. Mr. Braidwood was upon the spot very soon after the alarm had been given, and nearly the whole available force of the Fire-engine Establishment was summoned at his command. He appears to have at once foreseen that the fire would be one of no ordinary magnitude, and that the utmost that could be done would be to prevent its extending widely over adjoining property. The floating fire-engines had been got to bear upon the flames, and the men in charge of the branchpipes were, after two hours' work, already suffering greatly from the intense heat, when their chief went to them to give them a word of encouragement. Several minor explosions, as of casks of tallow or of oil, had been heard, but as it was understood that the saltpetre stored at the wharf was in buildings not yet alight, no alarm was then felt as to the walls falling in. At the moment, however, while Mr. Braidwood was discharging this his last act of kindness to his men, a loud report was heard, and the lofty wall behind him toppled and fell, burying him in the ruins. Those of his men who were near him had barely time to escape, and one person at his side, not a fireman, was overwhelmed with him. From the moment when the wall was seen to fall, it was known that whoever was beneath it had been instantly crushed to death. It is needless, and it would, indeed, be out of place, to describe here the further progress of the fire, which had then but fairly begun, and which was still burning more than a fortnight afterwards.
Great as was the general consternation at so terrible a conflagration, it is doubtful if the public were not still more impressed by the dreadful death of Mr. Braidwood, and by a feeling that his loss was a public misfortune. Her Majesty the Queen, with that ready sympathy which she has ever shown for crushed or suffering heroism, commanded the Earl of Stamford to inquire on the spot, on Monday, whether the body had yet been recovered by the firemen, and Her Majesty's sympathies were also conveyed to Mrs. Braidwood. It was not, however, until the following morning, that after almost constant exertions, under the greatest difficulties, the crushed remains were rescued. An inquest was necessary, not merely to ascertain what was already well known, thatdeath had been instantly caused by accident, but to know whether culpable carelessness of any kind had indirectly led to the sorrowful event. None, however, appeared. The remains of the fallen chief were afterwards borne to his late residence in Watling-street. The members of the committee of the London Fire-engine Establishment, formed of representatives from all of the twenty-five insurance companies of London, had already met to express, by a formal resolution, their sincere condolence with Mrs. Braidwood and her family. It was known that the funeral would take place on Saturday, June 29th, and it was widely felt that a general expression of sorrow and respect should be made, in view of the common loss of so valued a public servant, as well as for the noble qualities for which he had been so long and so well known. On the occasion of the funeral this was shown not more by the great length and marked character of thecortégeitself than by the general suspension of business in the leading thoroughfares of the city through which it passed, and by the hushed demeanour of the countless multitude who pressed closely upon the procession throughout its entire course. Among the thousands who sadly led the way to the grave were the London Rifle Brigade, about 700 strong (and of which Mr. Braidwood's three sons were members), the Seventh Tower-Hamlets, and other rifle corps, upwards of 1000 constables of the metropolitan police force, besides nearly 400 members of the city police, the superintendents and men of the various water companies, the secretary and conductors and the band of the Royal Society for the Protection of Life from Fire, a large number of private and local fire-brigades, and the members of the London Fire-engine Establishment.The pall-bearers were six of Mr. Braidwood's engineers and foremen, some of whom were at his side when he fell, and who had barely escaped with their own lives. Following the chief mourners were the Duke of Sutherland, the Earl of Caithness, the Rev. Dr. Cumming, and a large number of relatives and friends of the deceased, and the committee of the London Fire-engine establishment. The procession was nearly one mile and a-half in length, and was about three hours in its progress from Watling-street to Abney Park Cemetery, where the solemn service of the dead was conducted by the Rev. Dr. Cumming, of whose congregation the deceased had long been a member. With the exception of the great bell of St. Paul's, which tolls only on the occasion of the death of a member of the royal family or of a lord-mayor in office, the bells of all the churches in the city were booming slowly through the day, and so evident was the general sorrow that it could be truly said that the heart of the nation mourned.
On Thursday, July 4th, a public meeting was held at the Mansion House, when resolutions were passed for the collection of subscriptions towards a memorial to Mr. Braidwood's long and arduous public services. This memorial, it was felt, should take the form of a permanent provision for his family, for the post of Fire Brigade Superintendent had never been a lucrative one. Before, however, the collection of subscriptions had extended beyond a few hundred pounds, it was made known that the insurance companies had promptly settled upon Mrs. Braidwood the full "value"—speaking in an insurable sense—of her husband's life. Mr. Braidwood had for many years supported two maiden sisters, and thepublic subscription was applied, therefore, to the purchase of small annuities for each of them.
It will be remembered that the London Fire-engine Establishment was from the first controlled only by the insurance companies, upon whom of course, fell the whole cost of its maintenance. Their interest in the suppression of fires, although direct and unmistakeable, was not the same as that of the public. Thus, it would be to the public advantage that no fires should happen, whereas such a result would be fatal to the insurance companies, since no one in that case would insure. Although the protection of the Establishment was in practice extended alike to both insured and uninsured property, the real object for which it was formed and maintained was undoubtedly that of protecting insured property only. It was the interest of the companies to incur as little expense as would, on the whole, fairly effect this purpose, and it was not their interest to effectually protect the whole of the metropolis from fire. Thus it was that, with all the excellence of the organization and discipline of the Fire-engine Establishment, it was greatly inferior in extent to what was requisite for the proper security of the first city in the world. Mr. Braidwood had long felt this truth, but, acting for a private association, he could only go to the extent of the limited resources at his disposal. It was, more than anything else, the great fire at Cotton's Wharf that first directed public attention to the necessary insufficiency of any private establishment for the general suppression of fires, and that has led to the legislation under which the Fire-engine Establishment was, on the 1st of January last, taken over and extended by the MetropolitanBoard of Works. London will now, it is hoped, be better protected from fire, because of the increased extent of the means of protection; but it can hardly be expected that the discipline of the brigade will be improved.
Apart from the public value of Mr. Braidwood's career in increasing the common security against a common foe, there was much in his personal, intellectual, and moral qualities worthy of admiration. He was a man of strong and commanding frame, of inexhaustible energy, and of enduring vitality. The constitutions of but few men could have withstood such long continued wear and tear as fell to his. He braved all weathers, all extremes of heat and cold, could sleep or wake at will, and could work on long after others would have given way. He was always at his post, and in no moment of difficulty or danger did his cool judgment or his steady courage forsake him. It was this, together with his considerate bearing, and on occasions of special trial his almost womanly kindness to his men, that inspired them with unlimited confidence in him and in his plans. Beyond this, he was a man of superior mind, with strong comprehensive and generalising faculties. His various published papers, and a correspondence of which but few could know the extent and importance, as well as his ready, clear, and exact manner in stating his views before committees and before those in authority, who so often consulted him, all attest an order of mind which, in a different sphere, would alone have won distinction for its possessor. His profession was one in which it happens that almost every person thinks himself competent to give advice; yet, without any assumption of authority, Mr. Braidwood could make it felt wherever he pleased that he was a master in the art of extinguishing fire.But he was not on this account the less ready to listen to suggestions, and there are numbers who can bear testimony to the patient, honest, and appreciative manner in which he considered the many and diverse propositions submitted to him as the head of the Fire Brigade of the first city in the world. The soundness of his views and opinions is sufficiently attested by the success of his practice—a success which, but for the Government tax upon fire policies, would have long since made fire insurance in London almost the cheapest of all the forms of protection of property from danger. The London Brigade was insignificant in numbers and tame in display when compared with the eight hundredsapeurs pompiersof Paris, with their parade and all their accessories of effect—insignificant and tame, too, after the glittering apparatus, imposing paraphernalia, and deafening clatter of the "Fire Department" of New York; but Mr. Braidwood's chosen men knew how to do their duty, and considering the differences in the mode of building and of heating, and in the extent of lighting in the three great metropoli just named, it is an easy matter, on reference to statistics, to prove that none others have done better.
Above all, Mr. Braidwood was a gentleman of deep Christian feeling; and those who knew him best had never doubted that, had it been his lot to linger long in pain, knowing the end that was to come, his calm but unwavering faith in a better future would have sustained him through all. Brought up from childhood in the faith of the Scotch church, he was a regular attendant upon the ministrations of the Rev. Dr. Cumming. In his own quiet way he did much good in the poorer districts of London, and he took a specialinterest in the ragged schools of the metropolis. What he was in his own home may be best inferred from the crushing force with which his dreadful yet noble fate fell upon those who were dearest to him. His family had already too much reason to know the dangers which had always attended his career. A step-son had fallen, five years before, in nearly the same manner, and now lies buried in the same grave. Eleven members, in all, of the brigade, had perished in the discharge of their duty during the time Mr. Braidwood had commanded it: a fact which, taken with daily experience, pointed to other victims to follow. Such consolation, then, as a stricken widow and a mourning family could have, next to an abiding faith in the goodness of God, was in the recollection of the virtues and noble qualities of the husband and father, and in the spontaneous sorrow with which a great people testified their sense of his worth and of their common loss.
To show the universal as well as national esteem in which Mr. Braidwood was held, two extracts are here given from the numerous letters of condolence addressed to his bereaved family, from all parts of the world. Mr. G. H. Allen, Secretary to the Boston (America) Fire Department, writes: "It gives me pleasure to unite with the Board in testimony to the extreme kindness of Mr. Braidwood in the conduct of our correspondence, whereby we have been greatly benefited and received extensive information. Allow me also to extend our sympathy to those who have lost one who will ever be remembered as standing at the head of the most valued arm of the Government, and one that you can hardly expect to be replaced, except by years of experience and great natural ability." Mr. T. J. Bown, Superintendent of the Sydney(Australia) Fire Brigade, in a letter dated 22nd August 1861, says, "On receipt of the sad news, our large fire-bell was tolled, the British ensign hoisted half-mast high, and crape attached to the firemen's uniform, as a token of respect for one of the noblest and most self-denying men that ever lived, who spent and lost his life in the service of his fellow-creatures."

To prevent fires it is necessary to consider what are the principal causes of such calamities. These may be classed under several heads:—
1. Inattention in the use of fires and lights.2. Improper construction of buildings, &c.3. Furnaces or close fires for heating buildings, or for mechanical purposes.4. Spontaneous ignition.5. Incendiarism.
1. Inattention in the use of fires and lights.
2. Improper construction of buildings, &c.
3. Furnaces or close fires for heating buildings, or for mechanical purposes.
4. Spontaneous ignition.
5. Incendiarism.
As almost all fires arise from inattention in one shape or another, it is of the utmost importance that every master of a house or other establishment should persevere in rigidly enjoining and enforcing on those under him, the necessity of observing the utmost possible care in preventing such calamities, which, in nineteen cases out of twenty, are the result of remissness or inattention. Indeed, if any one will for a moment consider the fearful risk of life and property, which is often incurred from a very slight inattention, the necessity of vigilance and care will at once be apparent. Immense hazard is frequently incurred for the most trifling indulgences, and much property is annually destroyed, and valuablelives often lost, because a few thoughtless individuals cannot deny themselves the gratification of reading in bed with a candle beside them.
Some years ago, upwards of 100,000l.were lost, through the partner of a large establishment lighting gas with a piece of paper, which he threw away, and thus set fire to the premises, although it was a strict rule in the place that gas should only be lighted with tapers, which were provided for that purpose. In one department of a great public institution, it was, and is still, a rule that only covered lights should be carried about, and for that purpose four lanterns were provided; yet, on inquiry some time back, it was found that only one was entire, the other three being broken—one having lost two sides and the top; still they were all used as covered lights.
The opportunities for inattention to fires and lights are so various, that it is impossible to notice the whole.
One of the prevailing causes of fire is to be traced to persons locking their doors, and leaving their houses to the care of children. I believe one-half of the children whose deaths are occasioned by accident suffer from this cause alone: indeed, almost every week the newspapers contain some melancholy confirmation of what I have here stated. Intoxication is also a disgraceful and frequent cause of fire. The number of persons burned to death in this way is really incredible. It is true that it does not always happen that a fire takes place in the house, in either of the above cases, although the unfortunate beings whose clothes take fire, rarely escape with their lives; but the danger to the neighbourhood is at all times considerable, if persons in a state of inebriety are left in a house alone. When there is reason to apprehend thatany member of a family will come home at night in that state, some one should always be appointed to receive him, and on no account to leave him till he is put to bed, and the light extinguished.
I do not mean to say that people must be actually drunk before danger is to be apprehended from them. Indeed, a very slight degree of inebriety is dangerous, as it always tends to blunt the perception, and to make a person careless and indifferent. I may also add, that no inconsiderable number of fires are occasioned by the thoughtless practice of throwing spirits into the fire. The dresses of females taking fire adds very much to the list of lives lost by fire, if it does not exceed all the other causes put together.
Another very general cause of fire is that of approaching with lighted candles too near bed or window curtains; these, being generally quite dry, are, from the way in which they are hung, easily set on fire, and, as the flames ascend rapidly, when once touched, they are in a blaze in a moment.
It is really astonishing to find that, with daily examples before their eyes, people should persist (whether insured or not seems to make little difference) in practices which, there is a hundred chances to one, may involve both themselves and the neighbourhood in one common ruin. Of this sort are the practices of looking under a bed with a lighted candle, and placing a screen full of clothes too near the fire.
Houses not unfrequently take fire from cinders falling between the joints of the outer and inner hearths. When smoke is observed to arise from the floor, the cause should be immediately ascertained, and the inmates ought on no account to retire to rest while there is the slightest smell of fire, or any grounds to suspect danger from that cause.
Occasional fires are caused by a very absurd method of extinguishing at night the fires kept in grates during the day. Instead of arranging the embers in the grate in such a way as to prevent their falling off, and thus allowing the fire to die out in its proper place, they are frequently taken off and laid on the hearth, where, should there be wood-work underneath, it becomes scorched, and the slightest spark falling through a joint in the stones sets it on fire.
A very frequent cause of fire in shops and warehouses arises from the carelessness of the person intrusted to lock them up. It is no uncommon practice with those to whom this duty is intrusted, to light themselves out, or to search for any little article which may have been mislaid, with a lighted paper, and then to throw it carelessly on the floor, imagining they have taken every necessary precaution, merely by setting their foot upon it, forgetting that the current of air occasioned by shutting the door frequently rekindles it, and produces the most serious consequences.
In warehouses and manufactories, fires are not unfrequently caused by the workmen being occasionally kept late at work. By the time their task is finished, the men are so tired and sleepy, that the extinguishing of fires and lights is done in a very careless manner. I recollect an instance of this sort, in which the flames were issuing from three upper windows, and observed by the neighbours, while the workmen engaged at their employment in the lower floors knew nothing of the destruction that was going on above.
A very serious annual loss is also caused by want of due care in handing up or removing the goods in linen-drapers' shop windows when the gas is burning. Flues taking fire often result in mischief and it is believed thatmany serious fires have arisen from this cause, which can hardly be called accidental, as, if flues are properly constructed, kept moderately clean, and fairly used, they cannot take fire.
From what has been said, it will be seen that care and attention may do a very great deal towards the prevention of fire, and consequent loss of life. It is very easy to make good rules, and keep them for a time, after having been alarmed by some serious loss of property or life, but the difficulty is to maintain constant attention to the subject. The most evident plan for effecting this seems to be, for the masters thoroughly to examine and consider the subject at certain stated periods, not too far apart, and to constantly warn their domestics, workmen, or others, of the danger of the improper use of fires and lights.
One of the greatest preventives of carelessness in the use of fires and lights would be a legal inquiry in every case, as it would not only show the faults that had been committed, and thus warn others, but the idea of being exposed in the newspapers would be another motive for increased care. This plan has been adopted in New York, and the reports of the proceedings of Mr. Baker, the "Fire Marshal," show that the inquiries there made have led to most useful results. Mr. Payne, the coroner, held inquests on fires in the City of London some years ago, but the authorities would not allow his expenses, and therefore they were given up, although believed to be highly advantageous in explaining accidental and others causes of fire.
The improper construction of buildingsmore generally assists the spread than is the original cause of fires, although laying hearths on timber, and placing timber too near flues,are constant causes of fire, and it is believed that many melancholy occurrences have arisen from these and similar sources.
One cause of danger from chimneys arises from the communication which they often have with each other in one gable. The divisions or partitions, being very often found in an imperfect state, the fire communicates to the adjoining chimney, and in this way sometimes wraps a whole tenement in flames. I know a division of a principal street in Edinburgh, in which there is scarcely a single chimney-head that is not more or less in this condition; and I have no doubt that this is not an uncommon case. There is also great danger from the ends of joists, safe-lintels, or other pieces of timber, being allowed to protrude into chimneys. In one instance which came under my notice, a flue passing under the recess of a window had on the upper side no other covering than the wood of the floor; of course, when the chimney took fire the floor was immediately in a blaze: but there are many instances of such carelessness. It is a common practice amongst carpenters to drive small pieces of wood into walls for the purpose of fixing their work, not paying the least attention as to whether the points run into the flues or not.
In the repairs and alterations of old buildings, house-carpenters are, if possible, even more careless in this particular, than in the construction of new.
I know of two different buildings which underwent some alterations. In both of these, safe-lintels had been run into flues, and both of them, after the alterations, took fire; the one in consequence of a foul chimney, which set fire to the lintel; and although the other did not take fire from thesame cause, the lintel was nevertheless very much scorched, and obliged to be removed.
Great carelessness is frequently exhibited by builders, when erecting at one time two or three houses connected by mutual gables, by not carrying up the gables, or party-walls, so as to divide the roofs. I have seen more than one instance where the adjoining house would have been quite safe, but for this culpable neglect. It is no uncommon thing, too, to find houses divided only by lath and standard partitions, without a single brick in them. When a fire occurs in houses divided in this manner, the vacuities in the middle of the partitions act like so many funnels to conduct the flame, thereby greatly adding to the danger from the fire, and infinitely increasing the difficulty of extinguishing it.
In London the Building Act forbids all such proceedings, but the District Surveyors do not seem to have sufficient power, or be able to pay sufficient attention to such matters, as they are constantly met with at fires. A very flagrant case of laying a hearth on timber was lately exposed by a fire in the City. Due notice was given of the circumstance, but no farther attention was paid to the matter than to make the proprietor construct the floor properly, although the Act gave power to fine for such neglect. The omission is to be regretted, as there could not have been a better case for warning others; it occurred in a very large establishment, and the work was done by one of the first builders in the City. Had this fire taken place in the night and gained some head, it would have been very difficult to have ascertained the cause. As the premises were situated, a serious loss of life might have occurred, the apartment in which the fire originated being the only means of retreatwhich ten or twelve female servants had from their bedrooms.
The Metropolitan Building Acts, up to about the year 1825, by insisting upon party-walls and other precautions, were invaluable for the prevention of the spread of fires. By them no warehouse was permitted to exceed a certain area. From the year 1842, the area has been exchanged for a specified number of cubic feet. But since 1825, a class of buildings has arisen of which there are now considerable numbers in the City, called Manchester or piece goods warehouses, which somehow have been exempted from the law restricting the extent of warehouses, on the plea that they arenotwarehouses, because "bulk is broken" in them, although it is thoroughly understood that the legislature intended by the Act to restrict the amassing such a quantity of goods under one roof as would be dangerous to the neighbourhood.
Manchester and piece goods warehouses have for some time past been built in London of unlimited size, sometimes equal to twenty average houses. This is pretty nearly the same as if that number of houses were built without party-walls, only that it is much worse, for the whole mass generally communicates by well holes and open staircases, and thus takes fire with great rapidity, and, from the quantity of fresh air within the building, the fire makes much greater progress before it is discovered. By this means the risk of fire in the City has been greatly increased, not only to such warehouses themselves, but to the surrounding neighbourhood, for it is impossible to say how far fires of such magnitude may extend their ravages under untoward circumstances, there being at present no preventive power inLondon capable of controlling them. To provide such a power would be a very costly business.
Such buildings are also against the generally received rule, that a man may burn himself and his own property, but he shall not unduly risk the lives and property of his neighbours.
The new Building Act is likely to repress, to a certain extent, this great evil, unless its meaning be subverted by some such subterfuge as destroyed the efficiency of the last one. But what is to be done with those which are already built? It may seem tedious to dwell so much on this subject, but it appears to be a risk which is not generally much thought of, though it is of the most vital importance to the safety of London. It is very desirable that the metropolis should take warning by the experience of Liverpool, without going through the fiery ordeal which the latter city did.
From 1838 to 1843, 776,762l.were lost in Liverpool by fire, almost entirely in the warehouse risks. The consequence was, that the mercantile rates of insurance gradually rose from about 8s.per cent. to 30s., 40s., and, it is said, in some cases, to 45s.per cent. Such premiums could not be paid on wholesale transactions, therefore the Liverpool people themselves obtained an Act of Parliament, 6 and 7 Vic., cap. 109, by which the size and height of warehouses were restricted, party walls were made imperative, and warehouses were not allowed to be erected within thirty-six feet of any other warehouse, unless the whole of the doors and window-shutters were made ofwrought iron, with many similar restrictions. This Act applied to warehouses already built as well as to those to be built, and any tenant was at liberty,after notice to his landlord, to alter his warehouse according to the Act, and to stop his rent till the expense was paid. Another Act, 6 and 7 Vic., cap. 75, was also obtained, for bringing water into Liverpool for the purpose of extinguishing fires and watering the streetsonly. It is supposed that the works directed, or permitted, by these two Acts, cost the people of Liverpool from 200,000l.to 300,000l.Shortly after these alterations had been made, the mercantile premiums again fell to about 8s.per cent.
There is another very common cause of fire, which seems to come under the head of construction—viz., covering up a fireplace when not in use with wood or paper and canvas, &c. The soot falls into the fireplace, either from the flue itself, or from an adjoining one which communicates with it. A neighbouring chimney takes fire; a spark falls down the blocked-up flue, sets fire to the soot in the fireplace, which smoulders till the covering is burned through, and thus sets fire to the premises.
In theatres, that part of the house which includes the stage and scenery should be carefully divided from that where the spectators assemble by a solid wall carried up to, and through the roof. The opening in this wall for the stage should be arched over, and the other communications secured with iron doors, which would be kept shut while the audience was in the house. By this plan, there would be abundance of time for the spectators to retire, before fire could reach that part of the theatre which they occupy.
The danger from furnacesor close fires, whether for heating, cooking, or manufacturing purposes, is very great, and no flue should be permitted to be so used, unless it isprepared for the purpose. The reason is, that in a close fire the whole of the draught must pass through the fire. It thus becomes so heated that, unless the flue is properly built, it is dangerous throughout its whole course. In one instance of a heating furnace, the heat in the flue was found to be 300°, at a distance of from forty to fifty feet from the fire. In open fireplaces, the quantity of cold air carried up with the draught keeps the flue at a moderate heat, from the fire upwards, and, unless the flue is allowed to become foul, and take fire, this is the safest possible mode of heating.
Heating by hot air, steam, and hot water are objectionable. First, because there must be a furnace and furnace flue, and the flue used is generally that built for an open fire only; and second, the pipes are carried in every direction, to be as much out of sight as possible. By this means they are constantly liable to produce spontaneous ignition, for there appears to be some chemical action between heated iron and timber, by which fire is generated at a much lower temperature than is necessary to ignite timber under ordinary circumstances. No satisfactory explanation of this fact has yet been given, but there is abundant proof that such is the case. In heating by hot-water pipes, those hermetically sealed are by far the most dangerous, as the strength of the pipes to resist the pressure is the only limit of the heat to which the water, and of course the pipes, may be raised. In some cases a plug of metal which fuses at 400° is put into the pipes, but the heat to which the plug is exposed will depend very much on where it is placed, as, however great may be the heat of the exit pipe, the return pipe is comparatively cool. But even where the pipes are left open, the heat of the water at the furnace is not necessarily 212°. Itis almost needless to say that 212° is the heat of boiling water under the pressure of one atmosphere only; but if the pipes are carried sixty or seventy feet high, the water in the furnace must be under the pressure of nearer three atmospheres than one, and therefore the heat will be proportionately increased. Fires from pipes for heating by hot water have been known to take place within twenty-four hours after first heating, and some after ten years of apparent safety.
The New Metropolitan Building Act prescribes rules for the placing steam, hot-air, and hot-water pipes at a certain distance from timber; but as it must be extremely difficult for the District Surveyors to watch such minute proceedings, it becomes every one who is anxious for safety to see that the District Surveyors have due notice of any operation of this kind.
Another cause of fire which may come under this head is the use of pipes for conveying away the products of combustion. Every one is acquainted with the danger of stove pipes, but all are not perhaps aware that pipes for conveying away the heat and effluvia from gas-burners are also very dangerous when placed near timber. It is not an uncommon practice to convey such pipes between the ceiling and the flooring of the floor above. This is highly dangerous. Gas-burners are also dangerous when placed near a ceiling. A remarkable instance of this took place lately, where a gas-burner set fire to a ceiling 28-1/2 inches from it.
Another evil of furnaces is, that the original fireplace is sometimes not large enough to contain the apparatus, and the party wall is cut into. Perhaps it may be necessary to notice at this point the use of gas, as it is becoming so verygeneral. Gas, if carefully laid on, and properly used, is safer than any other light, so far as actually setting fire to anything goes, but the greater heat given out so dries up any combustibles within its reach, that it prepares them for burning, and when a fire does take place, the destruction is much more rapid than in a building lighted by other means. Gas-stoves, also, from the great heat given out, sometimes cause serious accidents; in one instance, a gas-stove set fire to a beam through a two-and-half inch York landing, well bedded in mortar, although the lights were five or six inches above the stone. This is mentioned to show that gas-stoves require quite as much care as common fires.
Spontaneous ignitionis believed to be a very fruitful cause of fires; but, unless the fire is discovered almost at the commencement, it is difficult to ascertain positively that this has been the cause. Spontaneous ignition is generally accelerated by natural or artificial heat. For instance, where substances liable to spontaneous ignition are exposed to the heat of the sun, to furnace flues, heated pipes, or are placed over apartments lighted by gas, the process of ignition proceeds much more rapidly than when in a cooler atmosphere. Sawdust in contact with vegetable oil is very likely to take fire. Cotton, cotton waste, hemp, and most other vegetable substances are alike dangerous. In one case oil and sawdust took fire within sixteen hours; in others, the same materials have lain for years, until some external heat has been applied to them. The greater number of the serious fires which have taken place in railroad stations in and near London have commenced in the paint stores. In a very large fire in an oil warehouse, a quantity of oil was spilt the day before and wiped up, the wipings being thrownaside. This was believed to have been the cause of the fire, but direct proof could not be obtained. Dust-bins also very often cause serious accidents. In one instance, 30,000l.to 40,000l.were lost, apparently from hot ashes being thrown into a dust-bin.
These accidents may in a great measure be avoided by constant care and attention to cleanliness, and where paints and oils are necessary, by keeping them in some place outside the principal buildings. Dust-bins should, as much as possible, be placed in the open air, and where that cannot be done, they should be emptied once a day. No collection of rubbish or lumber of any sort should be allowed to be made in any building of value.
Mr. Wyatt Papworth, architect, has published some very interesting notes on spontaneous ignition, giving several well-authenticated instances.
Incendiarismmay be divided into three sorts—malicious, fraudulent, and monomaniac. Of the former there has been very little in London for many years. The second, however, is rather prevalent. The insurance offices, which are the victims, protect themselves as well as they can, but an inquest on each fire is the true mode of lessening the evil. This is much more the interest of the public than at first seems to be the case. In several instances where the criminals were brought to punishment by Mr. Payne's inquests, people were asleep in the upper parts of the houses set fire to, and in one case there were as many as twelve or fifteen persons. This, however, is seldom stated in the indictment, as, if it is, the punishment is still death by the law, and it is supposed that a conviction is more easily obtained, by the capital charge being waived. Monomania is a rare cause of incendiarism,but still several well-certified cases have occurred in which no possible motive could be given. In one instance a youth of fifteen set fire to his father's premises seven times within a few hours. In another, a young female on a visit set fire to her friend's furniture, &c., ten or eleven times in the course of one or two days. In neither case could anything like disagreement or harshness be elicited, but the reverse. In other instances, it has been strongly suspected that this disease was the cause of repeated fires, but there was no positive proof. In all these cases, known or suspected, the parties were generally from fourteen to twenty years of age.
What is "Fire-proof Construction?" is a question which has given rise to a great deal of discussion, simply, as it appears to me, because the size of the buildings, and the quantity and description of the contents, have not always been taken into account. That which may be perfectly fireproof in a dwelling house, may be the weakest in a large warehouse. Suppose an average-sized dwelling-house 20 × 40 × 50 = 40,000 cubic feet, built with brick partitions, stone or slate stairs, wrought-iron joists filled in with concrete, and the whole well plastered. Such a house will be practically fire-proof, because there is no probability that the furniture and flooring in any one room, would make fire enough to communicate to another. But suppose a warehouse equal to twenty such houses, with floors completely open, supported by cast-iron pillars, and each floor communicating with the others by open staircases and wells; suppose,further, that it is half filled with combustible goods, and perhaps the walls and ceilings lined with timber. Now, if a fire takes place below, the moment it bursts through the upper windows or skylights, the whole place becomes an immense blast furnace; the iron is melted, and in a comparatively short time the building is in ruins, and, it may be, the half of the neighbourhood destroyed. The real fire-proof construction for such buildings is groined brick arches, supported on brick pillars only. This mode of building, however, involves so much expense, and occupies so much space, that it cannot be used with advantage. The next best plan is to build the warehouses in compartments of moderate size, divided by party-walls and double wrought-iron doors, so that if one of these compartments takes fire, there may be a reasonable prospect of confining the fire to that compartment only. Again, cast iron gives way from so many different causes, that it is impossible to calculate when it will give way. The castings may have flaws in them; or they may be too weak for the weight they have to support, being sometimes within 10 per cent., or less, of the breaking weight. The expansion of the girders may thrust out the side walls. For instance, in a warehouse 120 feet × 75 feet × 80 feet, there are three continuous rows of girders on each floor, with butt joints; the expansion in this case may be twelve inches. The tie rods to take the strain of the flat arches must expand and become useless, and the whole of the lateral strain be thrown on the girders and side walls, perhaps weak enough already. Again, throwing cold water on the heated iron may cause an immediate fracture. For these and similar reasons, the firemen are not permitted to go into warehouses supported by iron,when once fairly on fire.
Cast and wrought-iron have been frequently fused at fires in large buildings such as warehouses, sugar houses, &c., but according to Mr. Fairbairn's experiments on cast iron in a heated state, it is not necessary that the fusing point should be attained to cause it to give way.[A]He also states, that the loss of strength in cold-blast cast iron, in a variation of temperature from 26° to 190° = 164° Fahr., is 10 per cent., and in hot-blast at a variation of from 21° to 190° = 169° Fahr., is 15 per cent.; now if the loss of strength advances in anything like this ratio, the iron will be totally useless as a support, long before the fusing point is attained.
Much confidence has been placed in wrought-iron tie or tension rods, to take the lateral strain of the arches, and also in trusses to support the beams; but it must be evident that the expansion of the iron from the heat, would render them useless, and under a high temperature, it would be so great as to unsettle the brickwork, and accelerate its fall, on any part of the iron-work giving way: again, the application of cold water to the heated iron, in an endeavour to extinguish the fire, is almost certain to cause one or more fractures. The brick-arching is also very liable to fall, especially if only four and a half inches thick, independently of the weight which may be placed upon it, for it is not uncommon after a fire in a large building, to find the mortar almost completely pulverized to the depth of three inches, or four inches, from the face of the wall. When a fire occurred under one of the arches of the Blackwall Railway, on the 15th July, 1843, a portion of the lower ring fell down, and also a few bricks from the next ring.
Another very serious objection to buildings of this description, is that, unless scientifically constructed, they are very unlikely to be safe, even for the common purposes intended, independent of the risk of fire. In the Report of Sir Henry De la Bêche and Mr. Thomas Cubitt on the fall of the mill at Oldham, in October, 1844,[B]it is stated that the strength of the iron-beams was within ten per cent. of the breaking weight. Now according to Mr. Fairbairn's experiments on heated iron, already referred to, an increase of temperature of only 170° would have destroyed the whole building. It is quite clear, therefore, that so long as mill-owners and others continue to construct such buildings without proper advice, they must be liable to these accidents. In timber-floors there can be no such risk, as the strains are all direct, and any journeyman carpenter, by following good examples, can ascertain the size required; and even if he makes a mistake, the evil is comparatively trivial, as the timber will give notice before yielding, and may be propped up for the time, until it can be properly secured. In the case of fire-proof buildings, an ignorant person may make many mistakes without being aware that he has done so, and the slightest failure is probably fatal to every one within the walls. This also increases the difficulty and danger of extinguishing fires in a large building, as the only method of doing so is for the firemen to enter it with their branches, and in case of the floors falling, there is no chance of escape. On the other hand, timber-floors have repeatedly fallenwhile the firemen were inside the building, and they have made their escape uninjured.
In a pamphlet published by Mr. S. Holme, of Liverpool, in 1844,[C]and which contains a report from Mr. Fairbairn on fire-proof buildings, it is stated, that many people, especially in the manufacturing districts, are their own architects; that the warehouses in Liverpool may be loaded to one ton per yard of flooring; and that unless great care and knowledge are used in the construction of fire-proof buildings, they are of all others the most dangerous.[D]
The following are the principles on which Mr. Fairbairn proposes to build fire-proof warehouses:—
