What should you do if a boiler pressure gauge shows excessive readings?

When a boiler pressure gauge shows excessive readings, the appropriate response is to immediately shut down the boiler and investigate the cause. Excessive pressure can indicate a serious issue, such as a malfunctioning pressure relief valve, blocked safety devices, or other operational problems that could lead to a dangerous situation.

Shutting down the boiler promptly ensures safety, preventing potential hazards like explosions or system failures that could occur if the boiler continues to operate under abnormal conditions. Investigating the cause is essential for addressing the underlying issue and restoring safe operations before reactivating the boiler.

Other actions, such as checking the fuel level or adjusting temperature settings, do not directly address the critical safety concern of excessive pressure. Continuing to operate the boiler is particularly unsafe and could exacerbate the problem, making it a clear risk to both personnel and equipment. Proper procedure emphasizes safety and immediate responses to abnormal readings.
