Q: With the adoption of the new 2012 Life Safety Code by CMS, we had a discussion about projections from the corridor wall. Since the LSC only allows projections to be 4 inches, the question that came up was in regards to fire extinguishers mounted to the wall and not recessed as they project out from the wall about 7 inches. Will we be required to recess them or will they be allowed? The same question was raised about wall mounted telephones?
A: Actually, the 2012 LSC allows a 6-inch projection into the corridor [see 19.2.3.4(4)], but CMS’ Final Rule published April 4, 2016 said they will enforce the more restrictive 4-inch maximum projection into the corridor, based on the Americans with Disabilities Act (ADA). For all healthcare facilities that receive Medicare & Medicaid funds, they must comply with CMS’ exception to the 2012 LSC.
To answer your question, there are no exceptions to the 4-inch maximum projection rule. So, anything projecting more than 4 inches into the corridor, including fire extinguishers and telephones, would likely be cited by a surveyor or inspector.
