Standard Operating Procedure (SOP)

Formal methods or rules to guide the performance of routine functions or emergency operations. Procedures are typically written in a handbook, so that al firefighters can consult and become familiar with them.


Foot protection should provide the best protection against likely hazards that the rescuers will encounter:

heat, punctures, and impact


NFPA requires that rescue personnel wear ____ if they are likely to contact bodily fluids during a vehicle extrication.

medical exam gloves inside their leather or extrication gloves


The actual duration of respiratory support provided by a SCBA bottle depends on ____

the individual wearer's physiological and psychological conditioning.


What are the types of Air-purifying respirators

* Particulate removing
* Vapor and gas removing
* Combination particulate removing and vapor and gas removing


Canister or cartridge respirators pass air through a ____, ____, or ____ to remove specific contaminants from the air.

filter, sorbent, or combination of these


APR's should be worn only in ____ where the hazards present are ____ and at least ____ percent oxygen is present.

* controlled atmospheres
* completely understood
* 19.5%


Responders should be able to answer the following questions before deciding to use APR's

* What is the hazard?
* Is the hazard a vapor or gas?
* Is the hazard a particle or dust?
* Is there some combination of dust and vapors present?
* What concentration levels are present?


What are the three primary limitations of APR's?

* Limited life of its filters and canisters
* Need for constant monitoring of the contaminated atmosphere
* Need for a normal oxygen content of the atmosphere before use


Many vehicle hazards can be grouped into what two categories?

* Hazards from energy sources
* Hazards from beneficial systems


Isolate and manage conventional fuel systems using the following techniques:

* Place wheel chocks in front of and behind tires preventing unexpected movement
* Apply the emergency brake
* If the vehicle has an automatic transmission
- Place the gear selector in park
- Turn off the ingnition
- Remove the key
* If the vehicle has a manual transmission
- Turn off the ignition
- Remove the key
- Place the gear shift in the lowest gear
* Eliminate any ignition sources


If a vehicle is equipped with a smart key system and rescuers are unable to disable the 12 volt battery, ____

locate and remove the key from the area surrounding the vehicle. Be aware of the potential for a second smart key.


An alternative fuel is ____

a fuel that is not entirely derived from petroleum products.


Examples of alternative fuels

* Propane/ liquefied petroleum gas (LPG)
* Natural gas
* Auxiliary fuel cells
* Alcohol/ gasoline blended mixtures
* Biodiesel
* Aircraft fuel


When dealing with alternative fuels, rescuers have to exercise further mitigation techniques.

* Monitor the atmosphere
* Stay clear of vapor clouds
* Once the vehicle is secured and ignition sources are eliminated
- locate, access, and manually turn off the fuel at the tank shut-off valve.

800 volts


Rescuers should always assume that every hybrid electric vehicle is ____ despite a lack of engine noise.

powered up


The most desirable method for disabling a hybrid electric vehicle is to ____

shut down the vehicle with the switch and key system.


Disconnecting or cutting the 12 volt negative and positive battery cables in a hybrid electric car will ____

open relays to isolate the high voltage system.


Defoggers can ____ during window removal.

produce sparks or shock a person


Laminated safety glass consists of ____

two sheets of glass bonded to a sheet of plastic sandwiched between them.


Impact with Laminated safety glass produces ____. In addition ____ created from cutting this glass creates respiratory hazards.

* multiple long, pointed shards with sharp edges.
* any fine dust


Tempered glass is most commonly used in ____

side windows, and some rear windows.


Crushable bumpers are not a hazard until ____

the fire is out.
