Vol.II Flashcards
OSHA 29 CFR 1910.134(g)(4)
OSHA states that “once fire fighters begin the interior attack on an interior structural fire, the atmosphere is assumed to be IDLH and paragraph 29 CFR 1910.134(g)(4) [two-in/two-out] applies.”The plug person assumes the primary 2 in / 2 out position and the engineer assumes the secondary 2 in / 2 out position.
synthetic detergent that affects the physical properties of water.Foam solution is created when 0.1 – 1.0% foam concentrate is added to water.
Class A foam, CAFS.
Why should A & B foam not be mixed
concentrates will become gelatinous and clog most foam systems.
What benefit does adding air to foam have in battling class A fires
These bubbles effectively increase the surface area of water, thereby increasing the steam conversion and allowing for a greater absorption of heat and carbonized particles.
the time it takes for a company to reach their assignment area after receiving an order?
In transit
In transit times often varies due to:
• Distance between staging and the incident • Size of the incident perimeter • Amount of equipment the company needs to assemble
a forward staging position located just outside the immediate hazard zone, safely distanced from the entrance of a tactical position/Sector.
On Deck
Who is responsible for supervising on deck crews?
The sector officer, or the company officer.
The most likely assignments for On Deck companies are:
• Reinforce a position within an assigned sector • Crew relief within an assigned sector • Any other tactical position assigned by the IC • Rapid intervention crew
Once the IC has deployed units to the critical sectors around the incident scene who is best to serve as On Deck?
Units staged, Layering On Deck crews around the fire ground will also provide the IC with the tactical reserves to manage the standard work cycle or sudden and unexpected incident events.
A crew assigned to an On Deck position will need to park their apparatus…
In a manner that does not block access to the scene.
On deck crews must also size up the area that they are assigned to, this size up should include:
• Locating the structures entrance/exit points in their assigned area • Interior and exterior conditions • Unit ID of crews operating inside the structure • Approximate location of interior crews • Identify which crews are operating each hose line
When an on deck crew is used as a relief crew, the Company Officer should do a face to face and transfer information with the officer exiting the structure. The information transferred should include:
• Interior conditions • Routing instructions to the work area • Interior obstructions • Additional tools/resources required • Sector objectives
a timely and efficient means of air replacement and re-hydration of companies while maintaining their sector assignment.
Recycling Company officers should forecast the length of time they will be working in an assigned sector and should bring spare air cylinders if necessary.
Any situation where a firefighter is unable to safely exit the hazard zone or an event that cannot be resolved by that individual within 30 seconds
Mayday
Who’s responsibility is it to maintain a high level of Mayday readiness at all times? This includes everyday preparation and prevention as well as the practiced ability to communicate and respond to a Mayday scenario.
It is every individual firefighters responsibility.
NFPA 1500 Standard defines what?
mayday readiness as the ability to “don, doff and manipulate the SCBA in zero visibility while wearing firefighting gloves.”
The most important factors for Mayday prevention begin with the following operational standards:
Working within an Incident Command System/Risk Management System Working within the Incident Action Plan Always being accountable to someone within the incident command system (Never Freelance) Maintaining individual and crew air management Management of work cycles Monitoring distances traveled into buildings Layering of resources and providing for a tactical reserve Planning and acting out an exit plan
What are the two components of mayday readiness?
Prevention and response.
Individual firefighter responsibilities for Mayday prevention include the following:
Maintaining SCBA proficiency Practicing individual air management (task level of M.P. 202.05C) Use and care personal protective equipment Portable radio proficiency and use Practiced crew communications Roving/replacement firefighter integration into crew o Individual firefighters have to be responsible to ask if not initiated by Company Officer
Company Officer responsibility for Mayday preventions include:
Integrating a daily SCBA check into the crew routine Practicing crew communication in the hazard zone Rover integration into crew o Individual rovers are responsible to ask if not explicitly discussed at the beginning of a shift Maintaining knowledge of portable radios and practicing their use Ensuring Company Officer responsibilities and expectations are clear to the entire crew Practicing and maintaining crew integrity/accountability Instilling the standard that firefighters should always stay on a hoseline
At what level should the response to an individual firefighter’s Mayday should initially be managed at?
The company level
Once the Mayday situation is recognized and reported, what should each firefighter remember?
B.O.A. = Breath, Organize and Act
What is the IAFF Fire Ground Survival training?
SCBA familiarization o High/low profile wall breech o Disentanglement o Ladder bail o Window hang o GRAB LIVES G = Check Air Gauge R = Radio for Assistance A = Activate PASS Device B = Control Breathing, Conserve Air L=StayLow I = Illuminate, Turn Flashlight On V = Make Loud Noises (Volume) E=FindAnExit S = Shield Your Airway (last ditch effort)
