34 Pa. Code § 5.142 - Separator house

(a) Floors. The floor of a separator house shall be covered with sheet lead, with all seams and joints and burned in a careful manner, so that there are no crevices in which nitroglycerin may lodge. The floor shall be so constructed as to be readily washed and drained. The lead floor covering on new buildings shall be extended at least three inches up each side wall with rounded corners. A lead pan under the receptacle for holding nitroglycerin is acceptable in old construction in lieu of a complete lead floor covering.

(b) Thermometers. At least one reserve thermometer shall be kept in each separator house for use in case of emergency.

(c) Drowning tanks. An air agitator shall be provided for each separating tank and the outlet of each tank shall be suitably arranged so that the entire charge may be drowned in a drowning tank with a water capacity of at least five times that of the acid charge. Such tank shall be provided with an air agitator and water supply.

(d) Operation. The operation of each separator house shall conform with the following:

(1) No more than two charges are allowed in a separator house at one time.

(2) The maximum number of regular employes in each separator house shall be three.

(3) Stopcocks or valves on nitroglycerin pipelines or containers shall be of stoneware, earthenware, hard rubber or wood.

(4) Catch boxes shall be provided on all outlets for wash water and shall be kept clean.

(5) No charge shall be sent from the separator house at a time when a charge is being received.

(6) Each separating tank shall be cleaned and the floors washed at the conclusion of work each day.

(7) It is permitted to carry on nitration, separation and neutralization in one building, if not more than four persons are employed, and the regulations prescribed for each individual operation are complied with.
