Which of the following practices can help mitigate the risk of steam burns when operating a boiler?

Wearing personal protective equipment (PPE) is a fundamental practice for ensuring safety when operating a boiler. PPE such as heat-resistant gloves, safety goggles, long-sleeved clothing, and appropriate footwear provides a barrier between the operator and potential hazards like steam burns. This protective gear helps minimize the risk of injury caused by accidental exposure to hot surfaces or steam, which can lead to serious burns.

In contrast, the other choices would not effectively contribute to mitigating the risk of steam burns. Minimizing operator training would leave personnel ill-prepared to handle the hazards associated with boiler operation. Operating the boiler only during off-peak hours does nothing to address the inherent risks while working with high-pressure steam. Lastly, neglecting routine maintenance can lead to malfunctions that increase the likelihood of steam leaks or failures, further exposing operators to burns. Therefore, regularly wearing personal protective equipment stands out as the most effective practice for safeguarding against steam burns in boiler operation.
