Study Notes

Importance of Roofs in Firefighting

Roofs provide waterproof coverage, limiting fire penetration from aerial apparatus.
When roofs collapse, they can create a waterproof barrier over hidden fires beneath.

Firefighter Operations on Roofs

Firefighters utilize roofs for ventilating heat and combustion products from buildings.
Roofs offer vantage points for attacking fires in adjacent structures.
Firefighters operate underneath roofs while conducting interior fire attacks.

Knowledge of Roof Construction

Familiarity with roof construction is essential for firefighters, particularly its ability to support ventilation equipment.

Safety Considerations Regarding Roofs

Roofs are generally weaker than floors, designed for lighter loads.
Concealed spaces between ceilings and roof decks can hide fire development.
Added loads over time may exceed original design limits of roofs.
Roofs are prone to wear and environmental deterioration, leading to repairs and renovations.
Multiple layers of roofing materials complicate fire assessment and ventilation efforts.
