§ 456. Location of magazines. The quantity of explosives that may be
stored in any explosives factory or magazine shall depend upon its
distances from the nearest building, railroad or highway or other
magazine. The distances that a quantity of explosives may be stored from
the nearest magazine, building, railroad or highway, shall be as
determined by the regulations promulgated pursuant to this article. All
such distances may be reduced one-half when the magazine, building,
railroad or highway to be protected is adequately screened from the
explosives factory or magazine by an efficient barricade as defined in
subdivision seven of section four hundred fifty-one of this article.
