In which situation is a licensed fireman not needed in a boiler room?

A licensed fireman is generally required in boiler rooms to ensure safe operation and compliance with regulations. However, in the case of low pressure plants not exceeding 100 horsepower, the requirements may be less stringent. These plants typically pose a lower risk in terms of safety and operational issues compared to higher pressure systems, which could lead to explosive failures or significant hazards.

This exemption is based on the understanding that the complexity and potential dangers associated with low pressure operations do not necessitate the continuous presence of a licensed fireman. Although some regulations might vary by jurisdiction, the general industry standards recognize that lower horsepower boilers often allow for less oversight.

In contrast, high pressure plants require a licensed fireman at all times due to the higher risks associated with their operation. Fully automated plants may also be seen as requiring oversight from a licensed professional, even if many processes are automated. Similarly, during maintenance shutdowns, having a licensed fireman present is vital to handle potential emergencies, ensuring safety protocols are adhered to.
