Study Notes

Knocked-Down Fire Management

Localized fires, such as those involving mattresses or couches, can be confined to immediate areas and may not show extensive damage.
Distinguish between smoke, soot stains, and charred items; charred objects need water and must be opened up for thorough extinguishment.
Overhauling typically involves removing items outdoors to mitigate smoke sources and prevent reignition.

Fire Extinguishment in Mattresses

Complete extinguishment is challenging due to deep-seated fire embers that may not produce visible smoke.
Requires extensive opening and water application to ensure all fire is doused.

Caution When Transporting Furniture

Wet items thoroughly and extinguish visible flames before moving to minimize flare-ups when exposed to fresh air.
Transporting partially extinguished items via an elevator poses risks; avoid to prevent hazardous situations.
Do not discard smoldering debris out of windows, as it can reignite outside the fire crew's view; always soak charred waste.

Fire Room Overhauling

After flashover, logical opening sequences simplify the overhaul process and maximize safety.
Existing openings in barriers (like plasterboard) should be targeted first, particularly near light fixtures, pipes, and outlets to locate hidden fires.
Continuously inspect each bay until clean wood is found; be vigilant for vertical openings that can extend flames.

Pulling Ceilings Safely

Full protective gear and SCBA are mandatory while ensuring the area beneath is clear.
Openings should allow for egress in case of falling debris; ceiling materials can collapse unexpectedly.

Dealing with Tin Ceilings

Tin ceilings, initially fire-retardant, can hinder firefighting efforts due to their resistance to pulling and wedging tools.
Effective approaches include starting seams or openings first; visibility issues make locating seams difficult.

Overhaul Operations

Aimed at preventing additional water damage from firefighting efforts.
Smoldering debris should be opened and lightly watered rather than fully submerged for effective extinguishment.

Salvage Operations

Focused on minimizing damages from fire, smoke, and water.
Actions for salvage should start upon arrival; educate crews on the importance of leaving contents undisturbed whenever possible.
Strategies such as covering items or using preventive measures can greatly reduce damage.

Considerations for Moving Content

Treat the building's contents as if personal, recognizing the value of items to the residents.
Protect valuables via simple methods, such as covering with bedding or sealing items in drawers, to prevent damage during overhaul.

Utility Management

Notify utility companies promptly post-fire; firefighters can assist with electrical disconnection when safe to do so.
Approach utility shutoff with caution; proper equipment and knowledge of services are critical for safety during operations.
Always assume wires are live; utility personnel should handle live issues due to associated risks.
