5
The main objectives of overhaul are:
To provide for the safety of fire personnel conducting overhaul operations by limiting or removing exposure to _____/_____ atmospheres/substances and identifying/flagging _______ and _______ hazards that could potentially cause injuries or death.
Hazardous/ toxic
Structural and environmental
The main objectives of overhaul are:
To ensure the fire is out and all potential for ______ is eliminated.
Rekindle
The main objectives of overhaul are:
To leave the scene _______ – insofar as possible – for the purpose of aiding investigators and insurance adjusters in determining the most probable cause and property loss associated with the fire.

Identify and preserve all salvageable
The main objectives of overhaul are:
To ensure the premises are turned over to a responsible party, deemed either safe or unsafe to reoccupy as determined by _______, secured as needed to prevent unlawful entry and unauthorized acts, and checked a final time for rekindle prior to leaving the scene.
Authorities
_____ and ______ are currently the best lines of defense against any dangerous form of gases, vapors, and particulates.
Time and shielding
The environment directly following a fire incident should be considered _______ _______ to ____ and ______ (___) and treated as a hazardous environment.
Immediately dangerous to life and health (IDLH)
Studies have shown that ____ and proper ______ greatly reduce the levels of exposure to a hazardous environment.
TIME AND PROPER VENTILATION
It is important to remember that although carbon monoxide (CO) is a main contributor to an IDLH atmosphere, a CO measurement alone is not an _______ ________ as to whether or not other harmful chemicals are present.
ACCURATE INDICATION
consideration should be given to shutting down ______ and allowing the particulate matter to settle for a considerable amount of time prior to fire personnel reentering the occupancy to conduct overhaul.
Blowers
___ ____ should be employed to determine the proper level of Personal Protective Equipment (PPE) needed and to complete any necessary post-incident personnel exposure reports.
Gas meters
Firefighting gear provides protection from products of combustion in two forms:
Respiratory protection (scba) Skin absorption (turn outs)
NFPA specifically states, “The use of self-contained breathing apparatus (SCBA) by firefighters shall always be assumed to be in an atmosphere immediately dangerous to life or health (IDLH) because there is no way to predetermine those dangerous conditions, concentrations of toxic materials, or percentages of oxygen in air that exist in a fire environment, during initial overhaul (salvage) operations, or under other immediate emergency conditions involving spills or releases of chemicals or other toxic materials” This is nfpa_____
NFPA 1404-4
LAFD issued PPE for structure firefighting (turnouts) has a moisture and vapor barrier to provide this shielding. Although the firefighting ____ does not have a vapor barrier, it should be worn to minimize exposure from these toxins and vapors.
