We are midway through 2017, and 10 massive lightweight wood “toothpick construction” (LLW/TPC) that were in various stages of construction burned—many of them to the ground—causing numerous existing building exposure fires that displaced many families.
Although the code development cycle is currently reviewing Chapter 33—Fire Safety Under Construction and Demolition多多在线观看免费视频 proposals for the 2021 edition to address LLW/TPS under-construction concerns, there is still a need to address code sections for the ineffective National Fire Protection Association (NFPA)-13R (roulette) sprinkler system and amend it with a full NFPA-13 building sprinkler system as well as seek smaller footprints and height limitations with masonry walls from the foundation through the roof. In the existing building code, the LLW/TPS buildings seek a retrofit proposal to enhance current code sections on fire protection and life safety measures.
After the Boston 6th-alarm building under construction fire, “The city commissioner blasted construction workers for taking 90 minutes to report a fire that destroyed a six-story building in Dorchester last month and said city officials are working on new safety standards for buildings under construction, particularly those with highly flammable wood frames.”1

Proactive Fire Safety Measures
Some proactive actions a local fire department should advocate to its community for LLW/TPC buildings under construction include the following:
多多在线观看免费视频o To the owner:
–多多在线观看免费视频 Submit a site safety plan (to be approved by authority having jurisdiction).
>多多在线观看免费视频 No smoking or cooking on the premises.
> 多多在线观看免费视频Have a hot work policy in place and fire guard for cutting welding, grinding operations, and so on.
>多多在线观看免费视频 Appoint a certified site safety manager (SSM) during working hours.
多多在线观看免费视频Submit the SSM’s qualifications to fire code official for approval. If there’s no local program, refer to the Occupational Safety and Health Administration’s 10-hour training program that includes exit routes, emergency action plans, fire prevention plans, fire protection, and prevention.
- Hot work operations. SSM supervises and issues hot work permits.
- Maintain records of training
多多在线观看免费视频o Site safety training.
– Maintain records of weekly training sessions on:
> Use of a fire extinguisher.
> No smoking or cooking policies.
> How to report a smell of smoke or a fire.
> Hot work procedures, and so on.
多多在线观看免费视频o Post a patrolled 24-hour fire watch with the means to report a fire incident.
o Provide and maintain clear access routes for fire apparatus.
多多在线观看免费视频o Unannounced fire department onsite inspections or considerations for placing an engine company on site.
o Routine fire company preincident survey.
o Municipality to consider having the owner float a “conflagration fire bond” to cover the cost of all fire suppression and law enforcement operations.
Legislation prompted by the January 15, 2015, Edgewater, New Jersey, fire was stalled by trade group lobbying.3 With all of these LLW/TPC fires continually burning while under construction and occupied, trade groups are still lobbying at the state level and stalling legislation to go forward to enhance fire protection and life safety measures. (see .)
State and local fire organizations should challenge these trade groups and building owners with the videos of all these fires and refer to the 1995 Chesterfield, Virginia, fire. The United States Fire Association’s Technical Report Series on the Old Buckingham Station4 incident found key issues with the following:
- Large unsprinklered combustible spaces.
- Inappropriate sprinkler standard (NFPA-13D) was not intended for large structures.
- Draft stopping and tenant fire separations did not substantially protect combustible space whose ventilation openings into attic space at the building eaves and fire spread.
- Open combustible corridors and balconies and lightweight exterior wall finish supported rapid vertical and horizontal fire spread [refer to Occupied Fires/No.40 Chesterfield (VA) fire report (1995)].
Do we really need to wait for the next code cycle edition in 2021? The time is NOW for the trade industry to step up and take action to reduce fires at buildings under construction and enhance life safety measures by promoting an NFPA-13 full-building sprinkler system, smaller building footprints, height limitations, and masonry walls from the foundation to the roof for future occupants.

Key Issues & Comments
- Large Unsprinklered combustible spaces. The lack of automatic sprinklers in substantial combustible spaces allowed a large fire to develop.
- Inappropriate sprinkler standard NFPA 13D is not intended for large structures…or for other than use in one- and two-family dwellings and mobile homes.
- Draft stopping and tenant fire separations. The attic represented a substantial unprotected combustible space whose primary fire defense is the building code required draft stopping at tenant separation walls. Between effective draft stops, unimpeded fire growth can be expected and, with typical attic ventilation, plenty of air will be available for this growth. Stopping the fire’s spread at this point will depend on the integrity of the draft stops, fire department intervention, and the failure time of the construction. In this structure, the location of draft stops may not have coincided with tenant separation walls in all locations. The fire may have traveled thru the apartments under the draft-stopping.
- Ventilation openings into attic air vent openings at the building eaves permitted the fire to easily access the unprotected combustible attic space.
- Fire spread. The open combustible corridors and balconies and lightweight exterior wall finish supported rapid vertical and horizontal fire spread.
