Ch 9 Access Into Structures Flashcards
Scientifically controlled fire tests conducted by the NFPA® indicate that the time available for escape (TAE) from a burning building can be as little as ?
Scientifically controlled fire tests conducted by the NFPA® indicate that the time available for escape (TAE) from a burning building can be as little as 11 minutes after ignition due to heat buildup in a confined space such as a bedroom.
When a fire is burning inside a building, the IC has two basic choices?
When a fire is burning inside a building, the IC has two basic choices: (1) allow the building to burn and use the on-scene resources to protect any exposures, or as is most often the case, (2) order a search of the building and an aggressive interior attack on the fire.
If the building is showing signs of potential backdraft, entry should be delayed until?
If the building is showing signs of potential backdraft, entry should be delayed until the backdraft factors are mitigated.
There are several reasons why firefighters might need to gain access into a burning building. Of course, the most important reason is ?
There are several reasons why firefighters might need to gain access into a burning building. Of course, the most important reason is for search and rescue.
when cutting metal, these saws produce a tremendous amount of sparks that can ignite adjacent combustibles Therefore?
, when cutting metal, these saws produce a tremendous amount of sparks that can ignite adjacent combustibles. Therefore, rotary saws should not be used to cut metal where there are flammable fuels in close proximity.
One of the most important ways of ensuring the saw’s safety and effectiveness is by ?
One of the most important ways of ensuring the saw’s safety and effectiveness is by making sure that the saw blades are serviceable.
5 Point Door Size up
- Type of door (Style/material)
- Type of frame around the door (Wood/metal)
- Type of wall into which it is set (Wood/metal/masonry)
- Type of hinges/locks (Exposed/recessed/protected)
- Door movement (Swinging [inward/outward]/roll-up/sliding)
Before forcing any exterior door in a burning building, firefighters must?
Before forcing any exterior door in a burning building, firefighters must read the fire behavior indicators so they can anticipate how opening the door may change the fire behavior.
Tempered Glass —
Tempered Glass — Type of glass specially treated to become harder and more break-resistant than plate glass or a single sheet of laminated glass
In smaller buildings and occupancies that have relatively low occupant loads, the exterior doors open ?
In smaller buildings and occupancies that have relatively low occupant loads, the exterior doors open inward so the hinges are on the inside
In occupancies with higher occupant loads, the exterior doors must swing ?
In occupancies with higher occupant loads, the exterior doors must swing outward in the direction of exit travel.
In most cases, the hinges on outward-swinging doors are on the outside. However, the exterior doors in some commercial buildings are double-acting doors; that is, ?
In most cases, the hinges on outward-swinging doors are on the outside. However, the exterior doors in some commercial buildings are double-acting doors; that is, they swing both inward and outward on pivot pins top and bottom
What is one of the best tools to use for forcing an inward-swinging metal door set in a metal frame?
A rotary saw equipped with a metal-cutting blade is one of the best tools to use for forcing an inward-swinging metal door set in a metal frame
before opening a door into a burning building, firefighters must consider ?
before opening a door into a burning building, firefighters must consider the effects that
opening the door may have on the behavior of the fire.
What are some reasons to soften a building?
Forcing doors into burning structures is not always for the purpose of entering the building. Firefighters and others may be trapped inside and need an emergency escape route. It is SOP in some departments to force open all doors into a structure (sometimes called softening the building) when there is significant fire inside. However, softening a building is done only if it is consistent with the IAP and if it will not change the ventilation profile.
