Study Notes

Importance of Awareness

Recognizing a problem is crucial for initiating protective actions in firefighting.
The greatest risk during roof ventilation is from fellow firefighters, especially those using power saws.

Saw Safety on the Roof

Always lift the saw to a height clear of the roof cut when releasing it to prevent spinning.
Revving power saws on the fireground is extremely dangerous and should be prohibited.
Power saws have automatic clutches that keep blades spinning, posing a risk of severe injuries.
Keep the saw no higher than 6 inches above the roof and only rev the engine just before cutting.
After cutting a hole, lift the saw briefly and set it back down on the roof to stop the blade.
Clear personnel from the area before attempting to operate a malfunctioning saw.
Preferably, use a second saw instead of trying to keep a balky saw running.

Visibility Challenges

Poor visibility from smoke and darkness heightens the risk associated with live saws on the roof.
Firefighters should probe ahead with tools to determine safe footing, but this can be difficult.
If visibility is lacking, saw operators should stop all movements to avoid accidents.
In high heat situations, it's safer to drop and crawl toward safety rather than risk falling.

Steel Plating Risks

Steel plating added to roofs creates ventilation challenges and is often found on high-value properties.
This plating consists of 4x8 ft sheets, ⅛ to ½ inch thick, welded across the roof.
Fire departments need to assess the risk associated with such structures and consider mandatory sprinkler systems.
Warning signs must be posted regarding the presence of steel plating for firefighter awareness.
Early roof collapse is a significant risk due to the added weight of the plating.

Snow and Water Accumulation Hazards

Accumulation of snow or water poses an unpredictable weight hazard on roofs.
Stability checks should be performed before engaging in roof operations, particularly in inclement weather.
Example: A firefighter discovered 2 feet of snow on a parapet wall while operating on a burning tire store's roof.

Roof Team's Role

Roof operations are high-risk and require skilled firefighters to prevent disastrous outcomes.
Roof teams must operate with a strong understanding of their strategic importance and responsibilities.
They serve as the eyes and ears of the Incident Commander, reporting dangerous conditions promptly.
Failure to report hazards can lead to serious consequences for civilians and fellow firefighters.
