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)
3 types of power outages
Local- wires, poles down feeder- damages at substations rolling blackouts- power co. will discont. power in areas to reduce power consumption
what role does the engineer play in crew accountability?
- accountability officer that tracks who takes a hand line from his apparatus - collects passports from crews entering the hot zone - places passport on discharge gate when charged - places hoseline ID tag on hoseline
contents of a passport
-small co. ID tag - helmet id stickers - hose ID tag passports 3x4 tag
what replaces the passport pouch at the discharge gate when accountability is tracked in a sector
the small company id tag replaces the passport pouch
what situations will require a PAR?
- missing or trapped FF - change from off. to def. - sudden hazardous change - every 30 min elapsed - any time command feels necessary
in a 2 in / 2 out situation what role does the engineer play
the secondary position
who will be dispatched on all 1st.Alrm or greater as an additional layer of safety?
C957 north and south or BC152 and will fill the role of a mobile AISO
ISO responsibilities?
monitors IAP, conditions, activities and operations to determine whether the fall into the risk management plan
what are the different fire line tapes and what are they used for
-yellow line tape control bystanders. - white/red hazard tape helps control firefighters -red/black no access tape identifies exclusion zones for all personnel
on a large scale incident who or what is the sector responsible for additional supplies such as AFFF, field refueling, and delivery of fire hose.
resource sector, that operates under logistics. The resource officer may be paged or calling car 614
besides high rise fires, what other operations require a lobby sector?
Hazmat. ,confined space, trench rescue, water rescue, structural collapse
3 levels of evacuation
- site evacuation, small amount of people typically workers at the site - intermediate evacuation affects offsite homes and businesses normally less than 100 people - large scale thousands of people EOC will be actiavted to manage large scale evacs
how many gallons can a buoy wall tank hold?
3000-4000 gallons
how many gallons can a bambi bucket hold?
67-96 gallons depending on air temp and humidity
what are the steps for setting up a buoy wall
- lay out 1-2 salvage cover on a flat surface clear of over head obstructions - buoy can only be filled from the bottom - fill tank slowly until until about 1 ft. of water is in then increase pressure - foam can be added when water is about 1ft from the top. APPARATUS MUST BE 150’ TO THE SIDE OF THE FLIGHT PATH
When assigned to control a landing zone, what must be done.
- lay a line - pull 2 attack lines - lines are to refill belly tanks - wet down area - provide fire protection
when approaching a helicopter what safety precautions should be taken.
- approach only after making eye contact with pilot - pilot only can refill and rearm the belly - all refilling is to be done on the right side
crews shall approach and withdraw helicopters in which manner
to the front of the aircraft within 45 degrees
should anything ever become unsafe during a landing operation what should be declared the the pilot
GO AROUND, GO AROUND, GO AROUND
