Which action can cause burns and eye injuries in boiler operations?

Opening header drains can indeed lead to burns and eye injuries during boiler operations due to the high-temperature water or steam that can be released when the drains are opened. When header drains are operated, especially in a high-pressure system, the risk of hot steam or water escaping is significant. If proper procedures are not followed, operators are exposed to the potential for burns from contact with these heated fluids.

Additionally, without appropriate personal protective equipment (PPE), there is also a risk of steam or hot water splashing into the operator's eyes, leading to serious eye injuries. Proper training in boiler operations emphasizes the necessity of handling header drains cautiously and using recommended safety protocols to prevent such hazardous situations.
