For particular service, details for the theatres, balls, private clubs, etc., the number of men is fixed by the Préfet de Police, and there is extra pay in all these cases. The department is also called upon in case of street accidents, falling buildings, asphyxia in sewers, etc. The service material includes special apparatus for respiration in cellars, basements, etc., where the presence of gas or smoke is to be apprehended; and the great ladder, carried on a special truck, has a length of twenty mètres, greater than the average height of the Parisian houses. It is stated that the time allowed to elapse between the receipt of an alarm in the stations and the departure for the fire is often under a minute, and never exceeds two; in 1896, the time between the alarm and the attack of the fire was less than five minutes in ten hundred and seventy-nine fires out of a total of twelve hundred and four. In seven hundred and eighty-four cases, in the same year, the conflagration was completely extinguished in five minutes, and the very longest fire lasted six hours and a half. At the entrance of each of the twelve casernes, or barracks, of the regiment, the names of the officers and soldiers who have been killed in the discharge of their duty are engraved on a slab of black marble, the Golden Book of the regiment. In the court of the état-major the names of the forty sapeurs-pompiers who have thus died since 1821, are engraved on a marble panel. In his order of the day, March 11, 1888, "the colonel informs the regiment, with profound grief, of the deaths of Corporal Toulon and former sergeant Sixdenier, who perished yesterday, at noon, victims of their devotion, in endeavoring to save an imprudent workman who had descended, without taking precautions, into an excavation of the Rue des Deux-Ponts." Three citizens were also asphyxiated in trying to save him, two of whom died; "and the deaths of Sixdenier and Toulon will be for all another and a grand example to add to the history of the regiment."
