Nothing is Ever Routine: Residential Fire-Chicago LODD

 

Terrence Antonio James, Chicago Tribune

 

Nothing is ever routine;…… pause to reflect and remember the demands of the job and the inherent risks and the sacrifices made each and every day in this noble profession of the fire service.

Another beloved brother firefighter’s sacrifice, protecting the citizens of his great city.

Chicago Captain Herbert Johnson, 54, suffered second- and third-degree burns during fire suppression operations being conducted in the attic of the residential house at 2315 West 50th Place, according to Chicago FD officials and published media reports. The 32-year veteran of the Chicago Fire Department died Friday night after he and another firefighter were injured in a blaze that spread quickly through the 2-1/2 story wood frame house. The second firefighter injured was reported in good condition at Advocate Christ Medical Center in Oak Lawn, according to a department spokeswoman.

Captain Johnson, was promoted from lieutenant this summer and was assigned to Engine Co. 123 in Back of the Yards Section of Chicago for the night tour but normally worked all around the city.

Companies were called to the 2-1/2-story wood frame house at 17:15 hours on Friday evening. During initial fire suppression operations, a mayday for a trapped firefighter was communicated around 17:30 hours. Immediate RIT and rescue deployments brought the Captain and the other firefighter out of the structure.

Research identifies the residential occupancy building as being built in 1896 (age 116 years) and constructed of a common balloon framing system (type V wood) with a wood gable roofing system. Published photographs suggests that both original wood sheathing and shinges were present with some new outer sheathing materials being added and renovated at some point with some OSB type sheathing installed with rigid insulation boards and an outer vinyl siding system. Records indicate the house was approximately 2000 square feet in size and measured approximately 20 ft. x 60 ft. County documents indicated the roofing system was an asphalt shinge system on a wood plank deck. Post event photopraphs depict the typical framing system components, wall and roof system and collapsed materials.

The firefighters may have been caught in a flashover within the attic compartment according to early reports according to reports from department spokesman Larry Langford. “This fire is under investigation, and our main concern right now is the family,” said Fire Commissioner Jose Santiago, Santiago was joined at the University of Chicago Medical Center, where Johnson died in the emergency room, by officials including Mayor Rahm Emanuel.

Captain Johnson was the first Chicago firefighter killed fighting a fire since two firefighters, FF Edward Stringer and FF Corey Ankum died battling a blaze at an abandoned South Shore laundry in December 2010. (see previous CommandSafety.com coverage HERE and HERE)

Published reports poignantly stated the following;

“On behalf of the people of the City of Chicago, I want to express my condolences to the family and friends of Chicago Fire Department Captain Herbert Johnson, who tragically paid the ultimate sacrifice while battling a blaze early this evening,” Mayor Rahm Emanuel said in a written statement. “As we mourn Captain Johnson, we are all reminded of the dangerous job and selfless work of our brave firefighters. Being a firefighter is not simply a job, but a call to serve the public and greater good. In his 32 years protecting Chicago, Captain Johnson certainly exemplified the best traits in firefighters everywhere.”

Construction Insights for Typical Gabled Roof Attic with enclosed knee wall voids (typical examples) Occupied or Storage Attic Space Enclosure

  • Common attic spaces in buildings constructed of balloon framing systems may have the presence of knee wall voids or may have open ridge to eave
    clear space.
  • Knee wall spaces may be open to the compartment or may be enclosed and used for storage resulting in significant concentrated fire load. Inherent travel paths for fire due to non-fire stopped voids at the wall/eave interface results in concentrated fire impingement and degradation that can lead to isolated or catastrophic system failure and assembly collapse.
  • Age deterioration over many decades will commonly affect the structural integrity of the collar beams to maintain the structural stability of the roofing rafter system in the attic space. Renovations and alterations may also create operational risk hazards for conducting operations within fire induced attic compartments due to the absence of collar beams that further create unstable structural conditions to flame or heat affected roof components and systems.
