Class 5 Boiler Practice Exam

True or False: It is permissible to install one safety valve for multiple pressure vessels.

1. True

2. False

3. N/A

4. Requires specific approval

The correct answer is: False

The statement is false because safety valves are designed to protect individual pressure vessels by ensuring that the pressure within each vessel does not exceed safe limits. Each pressure vessel operates under specific conditions and requirements, which can differ from others. Installing one safety valve for multiple vessels could lead to inadequate protection for any one of those vessels, particularly if pressure conditions change or if there is a malfunction. Regulations and industry standards emphasize the necessity for dedicated safety mechanisms for each vessel, as this promotes safety and reduces the risk of catastrophic failure. Having independent safety valves allows for more precise control and timely reaction to pressure fluctuations, ensuring that each vessel remains within its designated operational parameters. Therefore, it is critical to follow these guidelines to maintain safe operating conditions and equipment integrity.
