How many safety valves are mandated on a steam boiler to ensure operational safety____________?
Show answer Hide answer
Answer: C. two
Explanation
Statutory boiler regulations mandate that every steam boiler must be equipped with safety devices. These valves automatically release excess steam pressure to prevent catastrophic vessel explosions. Therefore, exactly two independent safety valves are legally required on steam boilers. Safety valves are spring loaded mechanical devices set to lift at specific pressure limits. Redundancy ensures that if one valve jams, the second valve protects the vessel. Boiler inspectors test these valves regularly to guarantee compliance and safety.
Industrial safety standards prioritize human life and plant asset protection above all else. Over pressurization in steam boilers can lead to massive kinetic energy explosions. Operators face severe legal penalties if they operate boilers without certified safety valves. Four safety valves exceed statutory requirements for standard industrial steam boilers. Three valves are more than the legal minimum mandated by standard boiler codes. A single safety valve is prohibited because redundancy is essential for fail safe operation.
