N.Y. Comp. Codes R. & Regs. tit. 12, § 39.9 – Location of magazines.

(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.
