Study Notes
Subcellars
- Subcellars are located entirely below a cellar, making access and ventilation extremely limited.
- High-rise buildings often have multiple underground levels, numbered in ascending order; e.g., the first subcellar is two levels below street level.
- Firefighters must track their location accurately to ensure safety during operations.
- Fires in subcellars can be dangerous due to the extended use of self-contained breathing apparatus (SCBA), requiring a minimum of a 45-minute cylinder for firefighting.
Crawl Spaces
- Crawl spaces are under the first floor, designed for utility installations, and require crawling due to limited height.
- These areas typically feature rough concrete floors known as screed coats intended to minimize moisture.
- Access is often through small openings, making firefighting operations challenging.
- High-expansion foam can be beneficial for fire suppression in tight crawl spaces.
Below Grade Fire Indicators
- Smoke coming from every part of the building without visible flames can indicate a fire below grade.
- Dark smoke from chimneys and smoke seeping through cracks indicates a potential below-grade fire.
- Thermal Imaging Cameras (TIC) help detect heat but may not indicate concealed fires beneath flooring.
- Vigilance is crucial; past incidents show basement fires often result from wiring issues or combustibles.
Firefighting Tactics for Below Grade Fires
- A comprehensive size-up, including a 360° exterior survey, is essential before deploying hoselines.
- If smoke and heat are detected, use exterior streams to knock down fire quickly before advancing inside.
- Firefighters should aim for a swift application of water and be prepared to adjust tactics based on fire conditions.
- Specific attention should be given to common crawl spaces in multi-family structures, as they can facilitate rapid fire spread through utility lines.
Firefighting Safety Reminders
- Maintain awareness of any plan changes regarding hoselines and operations.
- Coordinate ventilation efforts with hoseline deployment to prevent fire spread.
- Avoid opening ventilation points above a fire, as this can create hazards for firefighters retreating from lower levels.
Recommended Practices
- During initial firefighting operations, applying hose streams from the exterior has been shown to improve conditions faster and more safely than interior-only methods.
- In multi-story buildings, approach from the same level or utilize stairways wisely, avoiding retreat through potentially compromised paths.
- Always ensure a charged hoseline covers areas where firefighters may need to retreat, protecting escape routes from fire regression.
