The number of pounds of explosives listed is the number of pounds of trinitrotoluene (TNT) or the equivalent pounds of other explosive. b. The distance listed is the distance to lot line, including lot lines at public ways. c. For the purpose of this table, an inhabited building is any building on the same tax lot that is regularly occupied by people. Where two or more buildings containing explosives or magazines are located on the tax lot, each building or magazine shall comply with the minimum distances specified from inhabited buildings and, in addition, they shall be separated from each other by not less than the distance shown for "Separation of magazines", except that the quantity of explosive materials contained in detonator buildings or magazines shall govern in regard to the spacing of said detonator buildings or magazines from buildings or magazines containing other explosive materials. If any two or more buildings or magazines are separated from each other by less than the specified "Separation of magazines" distances, then such two or more buildings or magazines, as a group, shall be considered as one building or magazine, and the total quantity of explosive materials stored in such group shall be treated as if the explosive were in a single building or magazine located on the site of any building or magazine of the group, and shall comply with the minimum distance specified from other magazines or inhabited buildings. d. Storage of explosives in a quantity exceeding 1,000 pounds in one magazine is prohibited. e. Magazine is a building or structure, other than an operating building, approved for storage of explosive materials. Portable or mobile magazines not exceeding 120 square feet (11 m 2 ) in area need not comply with the requirements of this code, however, all magazines shall comply with the New York City Fire Code. f. This table shall not apply to the temporary storage incidental to transportation.
