Study Notes
Spiral Staircases Hazards
- Spiral staircases are steep and tight, posing significant risks during below-grade fire maneuvers.
- They are often disorienting, complicating navigation in low visibility, such as heavy smoke.
- Missing risers increase the likelihood of flames reaching firefighters’ legs as they descend.
Straight-Run Stairway Benefits
- A straight-run stairway encloses at one or both ends, providing the easiest descent option in an emergency.
Safety Precautions for Descending Stairs
- Ensure a safe hose location and charge the line before advancing into the stairway.
- Swift water application is crucial to combat sudden fire vents.
- Seal off the stairwell using available doors to restrict fire access when retreating.
- Assess the integrity of each step before committing weight to prevent falls.
- For safe movement with hoselines, descend by sitting and sliding on the steps.
- Manage balance to counteract the nozzle reaction while descending.
Commercial Building Challenges
- Slides or chutes for merchandise create additional hazards for firefighters, risking falls into fire zones.
- Secure any slides to prevent dislodgment during hoseline advancement and warn all personnel about their location.
- Maintain a standby long ladder for emergencies if securing slides proves difficult.
Sidewalk Door Forcible Entry Issues
- Sidewalk doors often have inaccessible padlocks, requiring metal-cutting tools for entry.
- Initial attempts should focus on cutting down the seam between door halves.
- If unsuccessful, cutting hinges or prying the entire door from its frame may be necessary.
Elevator Shaft Awareness
- Sidewalk grates can hide elevator shafts, creating hazards if stepped into unexpectedly.
- Elevator shaft depths can vary, necessitating careful probing before stepping into openings.
- Open shafts may serve as ventilation points but should be treated with caution to avoid falls.
Historical Building Features
- Coal chutes were commonly used in older buildings for coal delivery, serving as potential ventilation points in fires.
- Hollow sidewalks are indicated by the presence of coal chutes and deadlights, which can collapse under heavy weight.
- Knowledge of these structures can aid in devising strategic firefighting approaches.
Fire Attack Coordination
- All personnel must clearly understand their roles before executing a fire attack from below grade.
- A backup hoseline should be established at the same entrance point to support the primary line.
- Decisions on advancing down tight staircases should be made by the officer based on fire conditions and stairway type.
Stairway Temperature and Safety
- The hottest area during descent is often 2-3 steps above the cellar ceiling; passing this point can result in easier access to cooler conditions.
- Use thermal imaging cameras (TIC) to monitor overhead dangers as firefighters advance.
- Maintain a lookout and clear paths for quick retreats based on changing fire conditions.
Air Supply and Exit Strategy
- Monitor air supplies closely, planning for timely relief to avoid hazardous situations.
- Relief teams must be ready to assist if conditions worsen, ensuring the stairway remains clear for quick exits.
Alternate Fire Attack Strategies
- Avoid fog patterns in enclosed spaces to prevent pressurizing fire areas; instead, use solid streams where conditions allow.
- Ventilation on the downwind side benefits the hoseline advancement, ensuring fire suppression without exacerbating conditions.
- Choose external entry points when available, facilitating direct access to fire zones and minimizing risk during the attack.
