Jan 17, 2025
What is Fire Hose? Types & Methods of Rolling Fire Hose
Introduction
Firefighting is a challenging field that relies on proper tools and equipment.
The fire hose is a crucial, complex, and versatile tool in firefighting.
What is a Fire Hose?
Specialized high-pressure tube that transports water or fire suppressants.
Can be connected to a fire truck, water pump, or indoor plumbing systems.
Operational pressure: 8-20 bar (800-2000 kPa or 116-290 psi).
Burst pressure capacity: up to 72 bar (7200 kPa or 1036 psi).
Construction
Made with woven fabric coated with rubber or PVC.
Outer layer: abrasion-resistant, tolerates UV light.
Inner layer: compatible with transported substances (water, foam, etc.).
Sizes
Diameters include: 25mm, 38mm, 50mm, 65mm, 80mm, 100mm.
Typical length: 30-50 meters.
How does a Fire Hose Work?
Uses water pressure to extinguish fires.
Connected to a water source such as a fire hydrant or pump.
The nozzle releases water under high pressure to disrupt and extinguish fires.
Different Types of Fire Hoses
Attack Hose:
Used directly on fires, light, flexible, 1.5 to 3 inches in diameter.
Supply Hose:
Larger diameter (3.5 to 5 inches), moves water from hydrants to fire engines.
Forestry Hose:
Lightweight for wildfires, handles outdoor conditions.
Booster Hose:
Rubber-covered, for small fires, diameters of 0.75 and 1 inch.
Suction Hoses:
Connects engines to water sources, handles vacuum pressures.
Relay and Supply Hoses:
Large-diameter (3.5 or 5 inches), for long distances.
Occupant Use Hoses:
For building occupants, typically 1.5 inches in diameter, 100 feet long.
Advantages and Disadvantages of Fire Hose
Advantages
Effectiveness:
Delivers high-pressure agents effectively.
Versatility:
Useful in various situations and fire types.
Ease of Use:
Straightforward with training.
Portability:
Lightweight and can be easily transported.
Disadvantages
Water Supply:
Requires significant water availability.
High Winds:
May affect trajectory of water/foam.
Potential Damage:
Susceptible to sharp objects, heat, chemicals.
Manual Labor:
Handling can be physically demanding.
Different Methods of Rolling Fire Hose
Straight Roll:
Simple, flat roll from male end.
Donut Roll:
Folded in half, rolled towards open ends.
Twin Donut Roll:
Similar to donut roll for larger hoses, compact.
Self-Locking Donut Roll:
Includes carrying loop.
Horse Shoe Roll:
Folded ends rolled towards the middle.
Conclusion
Comprehensive understanding of fire hoses is crucial for effective firefighting.
Knowledge of structure, types, and rolling methods improves emergency response and equipment maintenance.
Essential for firefighters, safety officers, and building managers.
