The Life Safety CodeMyths, Misconceptions & Opportunities
Code Problems In New Construction
Issue: How is it possible to end up with code violations after this process & what are the violations commonly identified after taking possession of a new building?

The Life Safety CodeMyths, Misconceptions & Opportunities
Code Problems In New Construction
- Why do they occur?- Complexity of codes
- Lack of LSC knowledge- Time is money- Value engineering- User influence
17
The Life Safety CodeMyths, Misconceptions & Opportunities
Code Problems In New ConstructionIssue: Common Violations - Not full sprinkler protection
- Utilities in exit stairs- Improper exit discharge- Oversize suites or exit issues- Inadequate building separation

Code Problems In New ConstructionIssue: Common Violations
- Room door swing into exit corridors- Wall projections- Stair width- Shaft enclosure- Improper fire stopping

The Life Safety CodeMyths, Misconceptions & Opportunities
Room Door SwingConcept: Doors from rooms should not interfere with exit corridors. Falls under 7.2.1.4.4 “Swing and Force to Open”
Premise: “During its swing, any door in a means of egress shall leave not less than one-half of the required width of an aisle, corridor, passageway, or landing unobstructed and shall not project more than 7 in. into the required width of an aisle, corridor, passageway, or landing, when fully open.”
The Life Safety CodeMyths, Misconceptions & Opportunities
Room Door SwingIssue: We find frequent instances where doors swing into egress corridors in new and existing buildings. In many cases these doors do not swing fully open due to door closers not opening 180 degrees, & due to objects interfering with their full opening such as handrails, soap/gel dispensers, lights, fire extinguishers, etc.

Fire Door Latching
Concept: Pairs of rated fire doors require positive latching to maintain their rating. The Code identifies specific # of latches for specific size and type doors
Premise: The number of latches required for a specific size Tin Clad Fire Doors can be found in section 3.4 of NFPA 80, Fire Doors & Windows under table 3-4.3.3(a)
The Life Safety CodeMyths, Misconceptions & Opportunities
Fire Door Latching
Issue: Tin Clad Fire Doors up to 6’6” in height require 2 latches & doors over 6’6” require 3 latches. Doors over 8’6” to 10’6” require 4 latches. Often the receptacle for the bottom latch has been removed from the floor. Also, many 6’6” fire doors are installed with only the top latch.

Fire Dampers
Concept: When an air duct penetrates multiple floors it is typically required to be enclosed with 1 or 2 hour fire resistive construction & provided with fire dampers where the duct penetrates the shaft wall
Premise: “Fire dampers shall be installed at each direct or ducted opening into or out of enclosures required by 3-3.4.1.” Falls under NFPA 90A 1999 edition “Shafts”.
29

Fire Dampers
Issue: Frequent improper installation of fire dampers in new & existing construction including:• Improper floor line installation• Improper wall installation• Improperly sealed penetrations

Locking Doors In Means Of Egress
Concept: Occasionally, for clinical safety reasons, a door in a means of egress may need to be locked. Falls under “Means of Egress Requirements”
Premise: The code states “Doors within a required means of egress shall not be equipped with a latch or lock that requires the use of a tool or key from the egress side. There are 3 exceptions.

Locking Doors In Means of Egress
Issue: Hospitals have a long history of locking certain high risk areas (particularly L&D & Newborn Nurseries) with non-conforming locking arrangements.
37

Fire Alarm Pull Box Locations
Concept: Fire alarm pull boxes should be located in the normal path of egress & near exits. Falls under NFPA 72 1999 edition.
Premise: Fire alarm boxes should be located within 5’ of exits, the top of the device should not be more than 54” from the floor & travel distance to a box should not be more than 200’.
The Life Safety CodeMyths, Misconceptions & Opportunities
Fire Alarm Pull Box Locations
Issue: Frequent findings of- Pull boxes mounted too high- Pull boxes over 5’ from exit- Horizontal exits w/o pull boxes- Mechanical room distances >200
41

“Tying-off” to Sprinkler Systems
Concept: “Sprinkler piping or hangers shall not be used to support non-system components.” Falls under NFPA 13, 1999 edition.
Premise: Designs for hanging sprinkler piping are based only on the weight of the water filled pipe & a safety factor, not extra weight.
42
The Life Safety CodeMyths, Misconceptions & Opportunities
Tying-off to Sprinkler Systems
Issue: Items supported by or on sprinkler piping is all to common a finding. It is even more problematic in older systems that have endured the effects of time & vibration for many years. TJC & CMS have become more aggressive in recent years in looking for this issue.

Corridor Walls
Concept: Corridors in hospitals mustbe separated from rooms by compliant partitions
Premise: “Corridors shall be separated from all other areas by partitions complying with 19.3.6.2 through 19.3.6.3” Falls under NFPA 101, 2000 edition.
