The presence of safety controls in the circuit is a fundamental safety measure required in a boiler room. Safety controls are critical for the safe operation of boilers as they are designed to monitor and manage various aspects of boiler function, such as temperature and pressure levels. These controls can include safety valves, pressure switches, and temperature sensors, which work together to prevent unsafe operating conditions and mitigate risks of overheating, explosions, or other hazardous situations.

The implementation of these controls helps ensure that the boiler operates within its designated parameters, providing an essential layer of protection for both the equipment and personnel working in the vicinity. In a scenario where a safety control detects an unsafe condition, it can automatically shut down the boiler or alert operators to take necessary action, thereby significantly reducing the risk of accidents.

While daily cleaning tasks, regular water testing, and constant supervision by an operator are also important for maintaining safe boiler operations and ensuring efficiency, they do not directly serve as immediate safety controls that can prevent accidents in real-time situations. Thus, the presence of these safety controls holds greater significance in directly safeguarding against potential boiler hazards.
