Section 8.80.110. Safety, safety relief, or relief valves.

Latest version.

	(a)  When two or more boilers operating at different pressures and safety valve settings are interconnected, the lower-pressure boiler or interconnected piping must be equipped with safety valves of sufficient capacity to prevent overpressure.  
	(b)  If in-service safety relief valve testing is impractical because a pressure vessel contains liquids or gases which are hazardous or costly, the testing may be performed at intervals not to exceed five years.
