my employer wants to put a locking door between two exit to prevent non-employees from hallway and locking exit doors this is on the second floor. i see someone getting trap if this is done. what do you think
If I understand your question:
you have two exits (exterior doors or doors to stairs);
you have a corridor connecting the two exits;
you have non-employees that will have access to one stair and part of the corridor;
under non-emergency conditions you want to limit the non-employees access to a portion of the corridor and the second required exit.
It sounds like you have a condition that requires electrically controlled egress door assembly, delayed-egress locking system, or access-controlled egress door assemblies. Take a look at the occupancy chapter and see if you can use the provisions of 184.108.40.206 of NFPA 101. There are similar provisions in the building codes.
Is there only one tenant/ business on the second floor???
Are there two separate exits on the second floor??
Do you know roughly how many sq ft the second floor is??
Normally if there are two required exits, anyone on that floor is required to have free, uninhibited access to both of them.
there are 8 people on second floor. at lunch time there may be 20 people cause of lunch room in located on same floor
yes there are two separate exits one on each end of floor
3,268 sq ft
As said most building codes require unimpeded access to both exits, for anyone that may come onto that floor.
You are right there should be no locks on doors in the means of egress that would trap anyone for conditions your employer wants. Without addition background from you I find it impossible to advise otherwise.
Life Safety Code Sections:
220.127.116.11 Locks, Latches, and Alarm Devices.
18.104.22.168.1 Doors shall be arranged to be opened readily from the egress side whenever the building is occupied.
Additional description of the arrangement would be most helpful to more fully answer your question.
In general, the LSC does permit security or traffic control doors within the "means of egress" which may limit traffic into certain areas. These may be secure, unrated cross-corridor doors of varying types. However, there are several LSC safeguards that must be followed when installing these doors and is based upon the level of security provided to ensure both employees and visitors may continue to reach exits during an emergency.
This is a fairly common example of where attempts to address a security concern may unknowingly create a life safety hazard. Only when both security needs and life safety requirements are considered as a whole can a solution be achieved that provides for both.
