Buffalo Fire Department Hose

Objective of this Lesson: To understand the various classification and types of hoses used by Buffalo Fire Department (BFD) and their specific applications.
Hose Classification:
- Supply Hose: Delivers water to the fire scene.
- Attack Hose: Used to apply water directly onto the fire.
Specific Classifications:
- Supply Hose:
  - Hard Suction Hose: Used to draw water from a draft source; comes in 4-1/2", 5", and 6" diameters.
  - Soft Suction Hose: Used to draw water from hydrants; comes in 5" and 6" diameters.
- Large Diameter Hose (LDH): Used to deliver a large volume of water with minimal friction loss; comes in diameters of 3-1/2", 4", and 5".
- Attack Lines: Used to apply water directly on fire; comes in 1-3/4" and 2-1/2" diameters.
Hose Construction:
- 1-3/4" and 2-1/2" Hose: Constructed with a rubber inner liner for leak prevention and reducing friction. The outer jacket can be made of cotton and synthetic or all synthetic materials.
- 5" Hose (BFD Usage): 3-ply construction with
  - Outer cover: Ribbed synthetic nitrile rubber.
  - Reinforcement: 100% circular woven polyester twill weave.
  - Inner liner: Ultra smooth, synthetic nitrile rubber.
Primary Causes of Hose Damage:
- Mechanical damage: Cuts, abrasions, and chafing.
- Chemical damage: Contact with acids, bases, gasoline, oil, paints, or other chemicals.
- Heat damage: Embers, flames, and indirect heat can damage the hose jacket and/or liner.
Special Procedures:
- Hose exposed to acids or bases should be thoroughly flushed at the fire scene.
- Prevent the runoff water from entering sewers or ground water supply.
