Restricted Access to Electrical Closets

Q: My questions are in relation to access control into electrical closets and life safety equipment closets. We have several electrical closets “locked down” by our IT department because they have installed network switches in these closets. One closet in particular also has an ATS switch and our fire alarm panel for that building. This closet is locked down to those who have “card access”. There are several closets that have life safety equipment inside that are also locked down with only card access. My questions are:

  1. Are there any compliance codes to refer to in accordance with life safety that states directly to our issue?
  2. Are there compliances that state “qualified persons” for access to electrical closets?
  3. Access to these electrical closets is limited. What codes or compliance regulation could this be violating?

A: From a Life Safety Code perspective the only compliance regulation that may apply concerns doors locked in the path of egress, which is section 19.2.2.2.4 of the 2012 Life Safety Code. It is permissible to lock the door going into the closet, but once you’re in the closet you cannot lock the door getting out of the closet. There are exceptions, and for closet it is rare to see any of the exceptions used under 19.2.2.2.4. Otherwise, I am not aware of any Life Safety Code issues that would prevent the locking of doors. In fact, HIPAA regulations would require the locking of closets that contain access to health information, so that is why the IT people want the doors to the intermediate distribution frame servers locked.

There are no regulations in the NFPA standards that state ‘qualified persons’ only for access to electrical closets

In an emergency, authorized individuals need to have access to electrical circuit breaker panels, disconnect controls, and the fire alarm panel. As long as the IT people allow unlimited access to certain Engineering-type staff (i.e. maintenance people) to the electrical equipment in these closets, I don’t see any problems.

Emergency Outlet Locations

Q: We are in the process of designing a new building for our ASC. I have been asked to mark the building plans with where I want the red outlets to be. What are the requirements for placement and number of red emergency power outlets?

A: If you are not an architect or an engineer, then I suggest you do not mark the drawings indicating where the red (emergency power) outlets should be. The location of red outlets is defined in NFPA 99 and the requirements to identify their location is the responsibility of the design professional in charge of the new facility. NFPA 99 is very specific as to where the red outlets should be, and how many. The 2012 edition of NFPA 99 has increasingly more requirements for the location of red outlets compared to previous editions, so it would be best that the professional who is in charge of the design be responsible to provide the locations of the red outlets.

I suggest you return this request back to the design professional without any locations identified by you, and inform the design professional that he/she is the person who is responsible to ensure the design of the new facility meets all of the requirements of the applicable codes and standards, which includes the locations of the red outlets.

Now, if the design professional is asking you to identify the location of red outlets in addition to those that are required by NFPA 99, then that is a different issue. But, that’s not what your question implied.
