Report, New York Board of Fire Underwriters, March 26th.

On the following pages will be found a brief resume of the suggestions from these sources of information, as well as recommendations as to the proper storage of pyrotechnics.

Location Of Arsenals

It is recommended that arsenals for the storage of pyrotechnic material be built as far away from habitations as is practicable.

The accompanying table gives the distances as recommended by the National Board of Fire Underwriters and the National Fire-Protection Association in reference to the nearness of these storage arsenals to highways, railroads, and neighboring buildings.

It will be noted that where large quantities, such as 500,000 pounds, are stored, the building should be located 3,000 feet from the nearest railroad and 2,000 feet from the nearest highway. This requirement, however, can be modified where such building, highway or railroad is effectually screened from the storage building, either by natural features of the ground or by an artificial barricade.

In reference to the location of buildings, the following is recommended:

Storage buildings to be located at a considerable distance from habitations, if practicable, and isolated so as to avoid the possibility of danger from external fires.

A unit spacing of not less than 400 feet to be observed and to be not less than 1,000 feet from any. highway.

A space not less than 50 feet around each building to be cleared and kept free from brush, and a space around building at least 10 feet wide, covered with cinders or some similar material that will prevent the growth of vegetation.
