What safety devices are commonly used in boiler operations?

The correct choice highlights the importance of safety devices that are integral to boiler operations. Safety valves, low-water alarms, and pressure switches play essential roles in ensuring the safe and efficient functioning of a boiler.

Safety valves are critical because they are designed to release excess pressure from the boiler, preventing dangerous situations such as explosions. When the pressure exceeds a predetermined limit, the safety valve opens automatically, allowing steam to escape and thus reducing the pressure to a safe level.

Low-water alarms serve as a vital warning system. They activate when the water level in the boiler drops below a safe threshold, alerting operators to take immediate action and prevent overheating or damage to the boiler. Maintaining adequate water levels is crucial in preventing situations that can lead to equipment failure.

Pressure switches are used to monitor the pressure within the system. If the pressure falls outside the acceptable range, the pressure switch can initiate safety protocols, such as shutting down the burner or triggering alarms to warn operators.

These devices collectively work to monitor and control the operating conditions of the boiler, safeguarding both personnel and equipment from potentially hazardous situations.
