(a) All fuel oil storage facilities shall be separated from the mixing plant and situated in such a manner that in case of tank rupture, the oil shall drain away from the mixing plant building.
(b) Buildings or other facilities used for mixing blasting agents shall be located, with respect to inhabited buildings, passenger railroads and public highways, in accordance with the table of distances cited in Table 1640.2.
(c) All internal-combustion engines used for power generation shall be located outside the mixing plant building, or shall be properly ventilated and isolated by a firewall. The exhaust systems on all such engines shall be located so that any spark emission cannot be a hazard to any materials in or adjacent to the plant.
(d) In determining the distance separating highways, railroads and inhabited buildings from potential explosions, as prescribed in Saf-C 1640, the sum of all masses which might propagate from either individual or combined donor masses shall be included. However, when the ammonium nitrate is included, only 50 percent of its weight shall be used because of its reduced blast effects.
