What is an example of a common hazard associated with boilers?

An explosion due to over-pressurization is a significant hazard associated with boilers. Boilers operate under high pressure, and if that pressure exceeds the design limits, it can lead to catastrophic failure. This can happen due to various reasons, such as a malfunctioning pressure relief valve, a blocked vent, or a failure in the boiler's control systems. In such cases, the pressure build-up can cause the boiler to explode, leading to severe injuries, property damage, and even fatalities.

Understanding the risks of over-pressurization is critical for those working with or operating boilers, as it underscores the importance of regular safety inspections, maintaining proper operational protocols, and ensuring that safety devices are functioning correctly. This awareness helps in mitigating the risk of such explosions, contributing to a safer working environment.
