Dear Mr. Reitze:

This is in response to your correspondence regarding your security door lock system presently installed in the Research and Development building.

29 CFR [1910.36(d)(1)] requires that ["Employees must be able to open an exit route door from the inside at all times without keys, tools, or special knowledge. A device such as a panic bar that locks only from the outside is permitted on exit discharge doors"].

The use of an electronic device that must be pressed before the panic bar can be activated violates the intent of 29 CFR [1910.36(d)(1)]. Employers utilizing such a system are cited. Employees trying to evacuate a smoke filled room may not be able to locate the electronic device and would be trapped at the exit door. Depression of the panic bar must open the exit without any prior action. Relays which signal a security monitor of the occurrence and which do not inhibit exiting are permitted.

It is suggested that Mr. Steve Crown, Branch Manager, Protection Services at Honeywell in Denver, be contacted for assistance in correcting the installation deficiency. Mr. Crown may be reached at telephone number 303-741-3002.

If we may be of further assistance, please call or write.


Bruce Hillenbrand
Deputy Director, Federal
Compliance and State Programs
