Staff On-Call Sleeping Rooms

Q: Does the Life Safety Code require hospital staff sleeping rooms have smoke detection inside the room and door closers installed? We have an on-call sleeping room for physicians in our Labor & Delivery unit and a consultant said we need smoke detectors and a closer on the door.

A: The answer is yes, the Life Safety Code (2000 edition), does require it. Section says where a mixed occupancy classification occurs, the means of egress facilities, construction, protection, and other safeguards must comply with the most restrictive life safety requirements of the occupancies involved. This means where there is a dominate occupancy (such as healthcare occupancy in the Labor & Delivery unit) that also has a small portion of a different occupancy (such as the staff on-call sleeping room which is actually hotels and dormitories occupancy) and these two occupancies are not separated by a 2-hour fire rated barrier, then this means the two occupancies are mixed, and the most restrictive requirements of both occupancies apply. As you indicated, hotel and dormitory occupancy does require single station smoke alarm and a closure on corridor doors to sleeping room (see sections and However, there is an exception to section which says where incidental to another occupancy, buildings used as follows shall be permitted to be considered part of the predominant occupancy and subject to the provisions of the Code that apply to the predominant occupancy:

  1. a) Mercantile, business, industrial, or storage use;
  2. b) Nonresidential use with an occupant load fewer than that established by Section 6.1 for the occupancy threshold.

This exception is allowing small incidental use of one occupancy to not have to comply with the requirements of that particular occupancy, and instead may comply with the requirements of the predominant occupancy, which in your case would be healthcare occupancy. There is only one catch, though. The phrase ‘incidental’ is ambiguous and is not defined. Therefore, the authority having jurisdiction (AHJ) gets to answer the question: What does incidental mean? I do not know what state and city you are located in, so I do not know who your AHJs are, but it’s a sure bet you have 5 or 6 AHJs who enforce the Life Safety Code, and it is likely that not all of them would make this interpretation the same way:

  • Joint Commission (or one of the other accreditation organizations)
  • CMS
  • State fire marshal
  • State public health
  • Local fire inspector
  • Insurance company

Since you have so many AHJs who have the right to interpret the phrase ‘incidental’, my advice is to take a very conservative approach and do not consider the exception, and go with installing a single station smoke alarm and a closure on the door to the corridor for the sleep room. By the way, most of the AHJs accept the fact that a smoke detector connected to the building fire alarm system in a hospital is equivalent to a single station smoke alarm, so you may be okay by just installing a smoke detector, rather than a single station smoke alarm. That’s your call.
