What are the main components of boiler safety systems?

The main components of boiler safety systems play a crucial role in ensuring safe and efficient operation. The correct answer highlights essential elements like pressure relief valves, low water cutoffs, and alarms.

Pressure relief valves are critical safety devices designed to prevent excessive pressure buildup within the boiler. When pressure exceeds a predetermined level, these valves open to release steam or water, safeguarding the boiler from potential explosions or catastrophic failures.

Low water cutoffs are another key component that protects the boiler from low water conditions. If the water level drops below a safe threshold, the cutoff triggers a shutdown or prevents the boiler from firing, thus avoiding overheating and damage to the boiler structure.

Alarms serve as warning systems that alert operators to abnormal conditions within the boiler. This can include high pressure, low water levels, or other potential malfunctions, allowing for timely intervention before a situation escalates into a safety hazard.

Together, these components form a comprehensive safety framework that helps maintain safe operational parameters for boilers, making option A the correct choice.
