Study Notes
Flat-Roof Operations
- Position apparatus at building corners to maximize scrub areas and reduce hazards from fire venting out windows.
- Use ladders at corners to access the strongest parts of the roof with fewer window risks.
- Check the distance from the top of the coping wall to the roof to gauge ladder placement safely.
- Estimate coping height by measuring from scuppers to the wall top or from vents to the top of the wall.
- Identify gas piping and machinery on the roof to assist with ventilation planning.
- Avoid placing ladders on coping due to potential instability and risk to firefighters; ensure ladders extend at least 6 inches above coping.
Gas Line Installation Hazards
- Gas lines run through wall spaces and trusses, vulnerable to damage during renovations or firefighting operations.
- Be cautious when accessing appliances, as flexible gas lines can be easily compromised by tools like axes and pike poles.
- Lines may exit through elbow fittings that can stress connections in confined spaces, leading to potential leaks.
- PVC pipes may encase gas lines but provide no real protection; lines remain unguarded in truss spaces.
Firefighting Strategy
- During fires, secondary hose lines may be deployed to protect exposures and control fire spread.
- The first engine may opt for rear or side access to basement fires, avoiding staircase "chimneys."
- If the initial line is in the basement, a second line should be positioned at the top of the basement stairs for safety.
- Communication with officers about actions taken is critical, especially concerning gas appliances.
Fire Fatalities Analysis
- When recovering fire victims, note their position, clothing adequacy for the weather, and any inconsistent injuries.
- Victims often found face down suggest attempts to escape; face-up positions may indicate collapse.
- Bright red blood pools under victims could indicate injuries prior to death, necessitating further investigation by the Fire Marshal.
- Documentation of the victim's condition and location is vital for fire investigation records.
