The question is asking for the regulations regarding the installation of safety valves on steam boilers. Safety valves are critical components in steam boiler systems, designed to prevent excessive pressure that could lead to equipment failure or accidents. The number of safety valves required depends on safety regulations and industry standards. Typically, a steam boiler must be equipped with at least one safety valve, but boilers with certain capacities or characteristics may require more than one to ensure safe and efficient operation. The answer choices suggest various numbers of safety valves, ranging from one to five. The correct answer depends on the specifications and safety requirements of the particular steam boiler in question.
