Arkansas Boiler Operator Practice Exam

True or False: You can check a safety valve by opening it at full working pressure.

1. True

2. False

3. Only if it's malfunctioning

4. Only if pressure is reduced

The correct answer is: False

Checking a safety valve by opening it at full working pressure is not advisable due to safety concerns. Safety valves are designed to release pressure automatically to prevent system overpressure situations. Opening the valve under full working pressure can expose operators and equipment to hazardous conditions. Instead, safety valves should be tested at a reduced pressure to ensure they function correctly without risking system integrity or safety. The proper procedure typically involves bringing the pressure down to a safe level before manually checking the operation of the valve. This is in line with best practices for maintaining boiler safety and compliance with regulatory standards, thus reinforcing that the answer is indeed false.
