Exit device hardware, also known as an fire exit hardware when used on fire doors, is designed to impart easy and fast egress to grant dwelling occupants to leave quickly in an emergency. Regulation publications characterize exit device hardware as, “a egress door-opening assembly incorporating a system that unlocks the handle up on the application of a force in the course of egress flow.”
Determining either the exit door of a work place require exit bar can be a challenge, even for the professionals. While most jurisdictions have utilized the IBC - International Building Code requisitions, It’s crucial to be aware that some areas like Manhattan New York where a city, a state or a county are dedicated to local requisitions vary and has to be advised by a skillful commercial lock smith in order to guarantee code compliance for the panic bar installation.
Basic requisitions:
Based on all releases of the IBC since the 2006 version, push bar is needed for doors catering three end users:
1. Building spaces with an inhabitant volume of at least 50 occupants.
2. Educational occupancies with an inhabitant volume of at least 50 occupants.
3. High hazard spaces with any tenant volume.
Be aware that above requisitions merely apply to doors that lock or latch. They don't ascribe if a door has pull/push hardware.
In dwellings that are required to observe NFPA 101 – Life Safety Code, there are four occupancy classes where panic device is needed:
1. Assemblage dwellings with an inhabitant volume of at least 100 occupants.
2. Educational occupancies with an inhabitant volume of at least 50 occupants.
3. Day cares with an inhabitant volume of at least 50 occupants.
4. High hazard dwellings with any tenant volume.
Be aware that if the place enclose electronic components, NFPA 70 – National Electrical Code may demand exit device to be installed. This recommendation was first composed in the 2002 version of the NEC, and has been changed in subsequent releases.
Starting with the 2014 version, doors that latch or lock, in the range of 25 feet of the specific work area,
catering the subsequent rooms, demand listed exit bar hardware:
1. Where electronic components is at least 800 volts and enclose overcurrent control or switching devices.
2. Where electronic components is more than 600 volts.
3. Battery chambers.
Commercial and residential dwellings like office buildings, apartments or retail facilities typically don't demand exit bar on any exit door except an high hazard, educational or assembly room inside the dwelling with an tenant volume of at least 50 occupants (based on the IBC) or at least 100 occupants (per NFPA 101). If these dwellings consists of electronic rooms that meet the principles above, push device would be required.
