Definition: Fire hose is a flexible, portable tube made from watertight materials, designed to transport water from a source or pump to a discharge point for extinguishing fires.
Types of Fire Hose:
- Supply Hose: Designed for moving water from a source to a pump supplying attack hoses or fire suppression systems.
- Attack Hose: Used by firefighters trained to combat fires.
- Fire Department Connection (FDC): Connecting point for the fire department to connect to sprinkler or standpipe systems.

Reliability: Fire hose must be constructed of high-quality materials, maintained per manufacturer recommendations, and designed for flexibility and watertightness.
Construction Types include:
- Single-Jacket Hose
- Double-Jacket Hose
- Rubber Single-Jacket Hose
- Hard-Rubber or Plastic Noncollapsible Types

Hose lengths: Manufactured typically in 50 or 100 feet (15 or 30 m).
Standard diameters: Common sizes include:
- 1½ to 3 inches for attack hose
- 2½ to 6 inches for supply hose
Minimum requirements are per NFPA 1961.

Fire hose couplings serve to connect hose sections and to connect hoses to nozzles, hydrants, and pumpers.
Coupling Types:
- Cast Couplings: Weak, generally found on occupant-use um
- Extruded Couplings: Generally the strongest and made from aluminum.
- Drop Forged Couplings: Made of brass or malleable metal, strongest.
Threaded Couplings: Include male and female components, must align and tighten hand tight to avoid damage.

Basic Hose Load Types:
- Flat Load: Easy to load, suitable for all sizes of supply hoses, lays flat.
- Accordion Load: Hose laid on edge in folds, allows for shoulder carry.
- Horseshoe Load: U-shaped configuration, reduces sharp bends.
- Combination Load: Allows for dual supply and attack lines simultaneously.
Finishes: Techniques for closing a hose load for quick access include straight and reverse horseshoe finishes.

Types of Damage:
- Mechanical Damage: Abrasions, cuts, and tears from sharp objects.
- Thermal Damage: Caused by exposure to heat or flames.
- Organic Damage: Caused by mildew or mold on natural fibers.
- Chemical Damage: Resulting from contact with harmful substances like acids.
- Corrosion: Occurs in metal fittings exposed to moisture.
- Age Deterioration: Damage due to age, folding, stress.

Regular inspection, washing, drying, and proper storage can extend the lifespan of fire hoses.
Inspection Procedure: Minimum frequency defined by NFPA 1962, involves checking conditions at couplings and hose jacket.
Washing: Best methods include rinsing and mechanical cleaning for woven-jacket hoses.
Drying Techniques: Must be ensured that hoses are completely dry before storage.
Storage Recommendations: Store away from direct sunlight and harsh chemicals.

Two-person method for operating attack hoselines is preferred: one holds nozzle, the other stabilizes the line.
Important to work with situational awareness; recognize potential hazards.

Hose Advancements: Techniques for advancing hoses up ladders, through buildings, and lengthy stretches are all crucial to effective firefighting.
Replacement and Repair: Specific procedures for replacing burst sections involving two new sections.

Annual service tests to maintain readiness, following NFPA 1962 guidelines for procedures and site preparation.
