NOTE: Provisions of this order do not apply to operations in the manufacture of pyrophoric substances.

(a) Pyrophoric substances shall, as far as practicable, be stored and handled under a suitable liquid which will prevent contact of the substance with air and with moisture if the substance reacts violently with water.

(b) Where such substances are handled or used in the dry state, the amount at each work station shall be not more than one half-day's supply or product; provided, however, that where less than one half-day's supply or product may constitute a serious hazard, the permissible amount may be restricted to less than a half-day's supply.

(c) Work stations where pyrophoric substances are used or handled in the dry state shall be separated by distance, barricades, or other means so that a fire in the substance at one station will not ignite a substance at any other station.
