Sec. 39.9. Location of magazines

(a) Quantity and distance tables.

(1) The following tables show the distances from nearest buildings, railroads or highways, as these terms are defined in article 16 of the Labor Law, that the respective quantities and types of explosive materials may be stored.

(2) For the purpose of compliance with this Part (rule), the weight of finished fireworks shall be considered as the weight of explosive materials stored in a magazine.

(3) The following distances in Table 1, “High Explosives Quantity and Distance Table,” may be reduced by one half when the building, railroad or highway to be protected is effectively screened from the explosives factory or magazine by an efficient barricade as defined in article 16 of the Labor Law.

(4) The board may authorize temporary deviations from the following quantity and distance tables when compliance therewith entails practical difficulties or unnecessary hardship, provided public safety is preserved.

(b) Quantity and distance requirements for blasting caps and detonating cord.

(1) Blasting caps.

The quantity and distance requirements for blasting caps shall be as follows:

(i) Cap sizes up to and including No. 8—1,000 caps shall be rated equivalent to one and one-half pounds of explosives.

(ii) Cap sizes larger than No. 8—1,000 caps shall be rated equivalent to three pounds of explosives.

(2) Detonating cord.

The quantity and distance requirements for detonating cord shall be as follows:

(i) Detonating cord containing up to and including 60 grains per foot shall be rated equivalent to nine pounds of explosives per 1,000 feet of cord.

(ii) Detonating cord containing more than 60 grains per foot shall be rated equivalent to 15 pounds of explosives per 1,000 feet of cord.
