Month 11; Chapter 18 Loss Control Flashcards
(21 cards)
Primary Damage
Caused by the fire and smoke
Loss Control
-Activities performed before, during, and after a fire has been extinguished to minimize losses to property.
Secondary Damage
Results from fire suppression activities such as forcible entry, ventilation, and fire extinguishment operations.
Loss Control
- Salvage
- Overhaul
Salvage
-Methods and operating procedures by which firefighters attempt to save property and reduce further damage from water, smoke, heat and exposure during or immediately after a fire; may be accomplished by removing property from a fire area, by covering it or by other means.
Overhaul
-Operations conducted once the main body of fire has been extinguished; consists of searching for and extinguishing hidden or remaining fire, placing the building and its contents in a safe condition, determining the cause of fire, and recognizing and preserving evidence of arson.
Salvage
-Begin upon arrival and continues until that last unit leaves the scene.
Salvage Procedures
- Moving contents to a safe location in the structure.
- Removing contents from the structure.
- Protecting the contents in place with salvage covers.
Salvage Procedures
Method most often used to protect contents is to leave them in the room in which they are found. Contents are gathered into compact piles that can be covered with a minimum of salvage covers.
-Creating one high point in the furniture group allows water to run off without it collecting in depressions.
Salvage Equipment
- Automatic Sprinkler Kit
- Carryalls, Debris Tarp
- Hall runners
- Water Vacuum
Utility Fold
- Takes 2 people to deploy
- Pleat and then fold
Accordian fold
- 1 person can deploy
- Fold and then pleat
Ballon Throw
-Most commonly used for two firefighter deployment of a large salvage cover. The balloon throw works best when sufficient air is pocketed under the cover. The pocketed air gives the cover a parachute effect that allows it to float into place over the article to be covered.
Water Chute
-One of the most practical methods of removing water that comes through the ceiling from upper floors.
Catchalls
-Can be constructed from salvage covers to hold large amounts of water.
Overhaul Safety
- SCBAs
- Charged hoselines
Locating Hidden Fires
- Evaluate structural condition of the area to be searched.
- Can often detect hidden fires by sight, touch, sound, or electronic sensors.
Overhaul Procedures
- Typically begins in the area of most severe fire involvement.
- Thoroughly check insulation materials because they can retain hidden fires for a prolonged period.
- If fire has burned around windows or doors, pull open these areas to expose the inner parts of the frame or casing and visually verify full extinguishment.
Overhaul Procedures
-When fire has burned around a combustible roof or cornice, it is advisable to open the cornice and inspect for hidden fires. In structures using balloon frame construction, check the attic ad basement for fire extension.
Overhaul Procedures
-When pulling any ceiling, do not stand directly under the area to be opened. Always position yourself between the area being pulled and the doorway to keep the exit route from being blocked with falling debris.
Overhaul with Thermal Imagers
-If there are discrepancies between the image shown on the TI and signs of fire in a concealed space, the space should be opened up and inspected visually.
