4K – Panic Hardware on Electrical Rooms

Some rooms containing electrical equipment are required to have doors that are equipped with panic hardware or fire exit hardware.  This is a requirement of NFPA 70 – National Electrical Code (NEC), and the purpose is to allow technicians to exit easily in case of an accident within the room.

Most jurisdictions within the US have adopted the NEC, but different editions of the code may be used from one state to the next.  NFPA 70 is updated every 3 years, and each edition since 2002 has made changes to the requirements for panic hardware so it’s important to know which edition applies to a particular project.

The NEC mandates panic hardware or fire exit hardware on rooms that house equipment over a certain amperage, or over a certain voltage – as specified in the code.  There are also requirements for specific types of rooms, such as transformer vaults and battery rooms.  Unlike the requirements for panic hardware in other types of occupancies, NFPA 70 does not require panic hardware serving electrical rooms to be installed on each door between the electrical room and the public way.

For more detailed information about panic hardware on rooms housing electrical equipment, read this Decoded article.  Then proceed to the review questions below.
