Each component has been tested to establish how much protection can be anticipated. The construction requirements also may extend beyond the structural frame. Due to compartmentation, a hospital will employ a 'horizontal phased evacuation'. LSC 2018, section 18.2.4.4.2, requires that a smoke barrier door must not serve as the only exit access from any space in a smoke compartment. At a minimum, they should include locations of all fire and smoke barriers, shafts, exit stairs, passageways, horizontal exits, suite boundaries, smoke compartments, hazardous areas, sprinkler protection and occupancy separations, such as for health care, ambulatory care and business. . For some occupancies, the requirement is limited to certain buildings within the occupancy classification, such as business occupancies with college or university classrooms (see 38.3.4.5) and occupant loads for new assembly occupancies (see 12.3.4.5). Understand NFPA 101: Life Safety Code and its impact on new and existing buildings.

They can be reached at lpeake@koffelcompliance.com and aellis@koffelcompliance.com.

The above exceptions apply to the sprinkler head component extending through the ceiling (for pendent sprinklers) or wall (for sidewall sprinklers). When life safety drawings show a storage room as a hazardous . However, there are two notable exceptions outlined in both NFPA 13 and the IBC, both of which basically outline that firestopping is not necessary when it will impair the ability of fire sprinklers to operate: 16.2.5.4 The use of caulking or glue to seal the penetration or to affix the components of a recessed escutcheon or concealed cover plate shall not be permitted. There are areas of a hospital, such as a neonatal intensive care unit (NICU), in which traditional alarm-notification appliances requirements (audible and visual) may present a risk to the patients that needs to be addressed using an alternative compliance strategy. On a related note, the code section is now clear that areas such as business occupancies on floors with a health care occupancy that are separated by two-hour fire-resistance-rated construction are not required to be subdivided by smoke barriers. Many organizations use a Barrier Management Program, restricting the access above ceilings to prevent unknown breaches in the fire barriers.

It may still be prudent to provide smoke barriers in the business occupancy portion of the floor to minimize complications if the area were ever to be renovated into a health care occupancy because constructing a new smoke barrier in an existing building is extremelychallenging. There has been a suggestion to add a decal or sign of some sort to cross-corridor smoke doors, so that clinical staff can easily identify where the next smoke compartment begins without referring to the emergency plans.

LSC 2018, section 7.7.2(3), added language that where an exit stair discharges to the interior of the building, exit signage identifiable from the point of exit discharge to the exterior of the building is a permittable alternative to the exit discharge leading to a free and unobstructed way to the exterior of the building. NFPA 101 does not include minimum requirements for the height and area of a building based upon construction type for all occupancies, but rather tends to limit such requirements to those occupancies in which evacuation times are expected to be longer (i.e., assembly occupancies, like a theater) or those occupancies in which the emergency procedures are likely to involve the relocation of the occupants instead of evacuation of the building (i.e., health care occupancies). Smoke compartments are created in health care occupancies to establish temporary areas of refuge involving the horizontal relocation of patients/residents by dividing most stories into compartments of 22,500 sq ft or less.

NFPA 13 says that, where quick-response sprinklers are used, all sprinklers within the same compartment need to be quick-response.
