§ 13.62. Safety equipment.

 (a)  The discharge from safety relief valves shall be vented away from the tank upward and unobstructed to the open air to prevent any impingement of escaping gas upon the tank. Size of discharge lines from safety relief valves shall not be smaller than the nominal size of the relief valve outlet connection. Suitable provision shall be made for draining condensate which may accumulate in the discharge pipe.

 (b)  Any portion of piping between tank and pump inlet or any wet hose which at any time may be closed at each end shall be provided with a relief valve to prevent excessive pressure from developing in the hose.

 (c)  If tank filling connections are located at a distance of more than 20 feet from a car or truck the pump discharge shall be provided with an excess flow valve.
