Construction in hospitals is so unavoidable, as it seems to go together like salt and pepper, but usually does not taste as good. You simply cannot renovate or remodel an area in the hospital without creating some sort of Life Safety Code deficiency. It’s a lot like cooking: You can’t make an omelet without cracking the egg! (Enough of the cooking references… My wife has me watching the Food Network too much!)
All of the authorities of jurisdiction (AHJ) know this, and they understand that at times, you will have to disable fire alarm and sprinkler systems; you will have to close exits and stairwells; and you will have to encroach upon the exit corridor width. Even the Life Safety Code (2000 edition) section 22.214.171.124 discusses the need to have alternative life safety measures in place during renovation. While some accreditation organizations actually call it “Interim Life Safety Measures”, the concept is the same.
Alternative (or interim) life safety measures requires the organization to make an assessment of the proposed renovation to determine if there will be any deficiencies made of the life safety features. If so, then the organization needs to decide what actions, if any, will be necessary to compensate for this deficiency. The Joint Commission requires that you place this decision process in the form of a policy with pre-determined plans of action already identified.
Other issues concerning construction are the barriers that separate the construction area from the occupied areas. Joint Commission only requires the barriers to be ‘smoke tight and flame resistant’, which can be accomplished with a certain type of flame resistant plastic sheeting. However, other AHJs, such as CMS and some state agencies, require compliance with NFPA 241 Standard for Safeguarding Construction, Alteration, and Demolition Operations, (1996 edition) which requires construction areas with ‘hot work’ to have 1-hour fire rated barriers as a separation from occupied areas. Hot work is defined as work involving open flame, grinding, cutting and welding. And, this 1-hour barrier needs to go from the floor to the deck above, unless it meets a horizontal surface that is also rated for at least 1-hour.
When the new 2012 edition of the LSC is finally approved by all of the AHJs, then NFPA 241 will include an exception that is not available in the 1996 edition. It will allow non-rated smoke tight barriers in lieu of 1-hour fire rated barriers provided there are active automatic sprinklers, which are properly installed, in the construction site. This will be a great savings for future construction projects.
If you are currently relying on the official position of The Joint Commission and only providing smoke tight barriers for construction sites, then you are exposed to other AHJ’s opinion that you need 1-hour fire rated barriers. At the very least, I suggest you call your state and local AHJs and ask them if they would accept the smoke-tight barriers. If so, then you don’t need to go the route of erecting 1-hour barriers. However, if they do require 1-hour fire rated barriers, then you will have time to change your policies to allow them for future projects.
Then everybody will be as happy as a clam (oops, there I go again.)
