What is the initial step to ensure a boiler's safety before maintenance?

• A. Check the steam pressure
• B. Ensure it is clean
• C. Confirm it is gas free
• D. Verify water levels

Answer: (C)

To ensure a boiler's safety before maintenance, confirming that it is gas-free is the initial and most critical step. This process involves ensuring all potentially harmful or explosive gases have been properly vented from the system, which is vital for the safety of personnel performing maintenance. If hazardous gas remains in the boiler, it poses a significant risk of explosion or poisoning during maintenance activities. Ensuring that a boiler is gas-free is part of standard safety protocols and must be performed before any physical work begins on the boiler. Once this critical step has been taken, additional safety measures can follow, such as checking steam pressure, verifying water levels, and cleaning the boiler. Each of these subsequent steps is important for the overall operation of the boiler but cannot supersede the necessity of first ensuring a safe environment free from gas hazards.
