At Bayonne a few years ago, a terrible fire started in a chemical works v\ere the silver salts were recovered from old films by dipping them into a hot solution of caustic soda. The accumulated gases caught fire and the whole building was blown up killing dozens of people. One of the most impressive features in this case was the extraordinary production of radiant heat, which at the distance of over seventy yards was still sufficient to melt telegraph wires, and to produce fires !
In the year 1925 in a laboratory at New-Jersey, placed into a so-called « fire-proof » building, and fitted with fire doors automatic extinguishers, with walls lined with asbestos, etc., a great fire took place. The inquest showed that the disaster had been caused by someone leaving open some of the doors.
Air. ~SIc Ilvane suggests a number of arrangements which we think it useful to report here : r° The vaults of the storage rooms must be well built. 20 Provide several fire extinguishers and aspirators in every storage room. 30 The doors must be made to close automatically and must remain always closed. 40 The electric wire circuits must be enclosed in lead pipes, and the light lamps must be made of globes containing steam or rarefied gases, and the switches must not give out any sparks when opening or shutting them. 50 Smoking must be strictly prohibited. 6° Film rolls must always be kept in metal boxes. 70 The boxes containingthe films must be kept at a good distance from the heating pipes or heat radiators, these latter should be enclosed in metal cages. 8° The glue for attaching the films, which is very inflammable must be kept always well closed and preferably in small quantities. 90 When preparing the films, the various small pieces or fragments must be thrown into special boxes which close automatically. io° Any other materials such as prints, paper, photos, etc., must be kept away at a good distance.
To these very necessary recommandations of Mr, Mc Ilvane, we may add that it is not difficult nor impracticable to follow even the most complex forms of fire prevention and order, especially for schools, Institutes, clubs and the like where a stock of films is generally kept. It is also advisable that the films should be stored in rooms situated at convenient distances from the school rooms, assembly rooms, etc., and in any case, in places which have no direct communication with the stairs, so as to avoid in case of mishap, that the smoke and fumes produced may not block the exit thus avoiding the possibility of grave disasters.
All that has been said above will have no value when the non-inflammable film, which is bound to come, will be introduced everywhere to replace the present film, and more especially in the field of educational cinematography which does not require to project great lenghts of films on the screen.
