(a) Hose lines. The transmission of nitroglycerin through hose lines shall conform with the following:
(1) In cold
weather, hot water shall be sent down through a hose line or in a gutter
surrounding the hose line both before and after a charge of nitroglycerin is
sent down the line.
(2)
Nitroglycerin lines shall be carried on substantial scaffolding or runways
protected by suitable covering.
(3)
A thorough examination of the complete system shall be made each day.
(4) No nitroglycerin lines shall pass an
explosives building at a distance near enough to cause serious injury if an
explosion occurs in the hose line.
(5) Hose lines shall be composed of rubber of
the highest quality.
(b) Gutters. When lead gutters are used instead of hose lines, they shall be formed of at least 6 pound lead, suitably lead-burned and located so that they will drain completely toward one end. Rubber gutters are permissible if they are of the highest quality rubber only.
(c) Carriages. Carriages for the transportation of nitroglycerin shall be properly designed and equipped with rubber tires. Smooth runways for such carriages shall be provided and kept in good repair at all times.
