LA has been involved with Community Risk Reduction since our inception in Our parent organization is called the Safe Community Project, Inc. Our purpose for existing is based around creating a safer community.
Building professionals and engineers are working to decrease the time involved in not only the production but the installation, too. Cost is clearly the driving force in these decisions — and a physical example of this evolution has been the introduction of lightweight construction.
The result is progressive structural collapse due to the failure of these lightweight structures, resulting in firefighter injuries and death. Over the past few years, you may have noticed an increase in reports of firefighter close calls and fatalities related to lightweight construction, which has hopefully created better awareness of the issue within the fire service.
It has forced departments to evolve further to differentiate between conventional framing and those using lightweight pre-engineered materials. The introduction of lightweight construction materials should have changed the way you operate on the fireground.
A series of tests done by the UL offered some glaring results. But the goal of this article is not to overwhelm you with scientific facts, codes and potential resolutions. One was older construction.
The other was made from newer lightweight materials. Loudoun County Fire Marshall Keith Brower talks about the lessons learned from comparing the two fires.
How can you protect you and your fellow firefighters? It is fairly easy. Firefighters need to develop a culture of continual and evolving size-up. Size-up will also need to evolve over time to allow for changes in the fire industry, the construction industry, and changes in your own response area.
Size-up for today is only as good as today. We need to educate our firefighters to be able to rapidly identify various types of construction, and the methods and materials utilized.
Consider developing a system to notify responding firefighters of potential construction hazards. Certain communities have already developed a hazmat-like placard system that allows responding firefighters to determine the type of construction upon arrival.
Collapse can often be catastrophic in lightweight construction compromised by fire.
Firefighters should be trained in not only the construction types and methods, but also to understand the differences in fire behavior as a result of different construction methods.
Building construction will determine the number of firefighters, apparatus and equipment needed to control fire, proper location of attack and vent, and whether the attack should be an offensive or defensive one.
Leadership must clearly understand fire progression and constantly assess the time the fire has been involved. There may be certain fires that may be an exterior attack on arrival just as a result of the amount of time the run was dispatched and the amount of time it took to respond.
Six minutes is a very small window to operate under. Use a defensive strategy whenever trusses have been compromised or exposed to fire, and remember basic risk reward concepts. Conduct search and suppression drills that emphasize tool use.
Firefighters must continually move with a tool to feel ahead of themselves. Using a tool will allow the firefighter to sound out the floor to get a sense of structural integrity.
The tool can also be used to sweep ahead of them to feel for already collapsed or compromised areas of flooring. Check out the following video: NIOSH provides the following recommendations to firefighters based on previous fatality-related incidents: Use extreme caution when operating on or under truss systems.
Notify the incident commander whenever truss construction is discovered. Communicate interior conditions to the incident commander as soon as possible and provide regular updates. Use a defensive fire-fighting strategy once burning of truss members is identified unless someone is trapped.
Expect imminent collapse once lightweight truss roofs or floors are involved in a fire Klaene and Sanders If possible, avoid cutting the truss chords when cutting holes for roof ventilation.MySafe:LA has been involved with Community Risk Reduction since our inception in Our parent organization is called the Safe Community Project, monstermanfilm.com purpose for existing is based around creating a safer community.
The public expects that certain services be provided by local government, including police protection, fire protection, and various city services, such as water and power. Jun 15, · The L.A. Fire Department is lagging on inspections for about 6, buildings — a third of the structures the LAFD classifies as a priority.
Above, the Millennium Biltmore Hotel. Apr 12, · March 9, LAFD explains shifting statistics: Top brass at the Los Angeles Fire Department admitted that for years the agency put out data that made it appear that firefighters were arriving at the scene of emergencies faster than they actually were.
Dedicated to the Art and Science of Building Construction, Firefighting and Command Risk Management for Operational Excellence and Firefighter Safety.
The Los Angeles Fire Department Leadership Academy provides a skill set that builds upon the foundation which is necessary for successful leaders. Our program utilizes case study methods anchored in multiple theoretical domains.
