If the boiler room entrance is only accessible from outside, where should the emergency switch be placed?

The emergency switch should be placed inside the boiler room, not more than a foot beyond the door opening. This placement is crucial for safety, ensuring that anyone entering the space can quickly access the emergency shut-off in case of an emergency situation, such as a fire or equipment malfunction. By having the switch immediately accessible, it minimizes the response time to shut down the boiler systems, which can be vital in preventing accidents or further damage.

This proximity also complies with safety regulations that aim to protect individuals in high-risk environments. Emergency switches are designed to be easily reached without having to fully enter the room, allowing for quick intervention while also maintaining a degree of safety for the personnel outside the boiler room.
