WATER DELIVERY COMPONENTS AND ACCESSORIES Hose Type: Semi-rigid hardline hose, with a working pressure of 300 psi. Construction and materials: Lightweight woven fabric of spun polyester warp yarns with plastic helical reinforcement component and elastomer extruded tubing. Weight: Uncoupled w-inch (lb/100 feet) = 16; 1-inch (lb/100 feet) = 21. Available: Fire equipment suppliers (see appendix G). 50 foot 1 inch 10.5 lb/50 feet (uncoupled) Commercially available 100 foot 1 inch 21.0 lb/100 feet (uncoupled) Commercially available Written material: Hardline Hose Comparison Study, Tech Tip 0251 1307— SDTDC, is available from: USDA Forest Service Technology and Development Center 444 East Bonita Avenue San Dimas, CA 91773 Phone: 909–599–1267 h. Relay-supply large diameter hose A single-jacket relay-supply hose has seen increasing use in the United States by fire departments. The single-jacket, made of all-synthetic fibers, is coated inside and out with a thin protective coating. The hose is available in 32- , 4-, 42- , 5-, and 6-inch diameters, and is often coupled with a lightweight aluminum alloy quick-connect coupling. The hose is intended for supply line use only from a water source to the engine. It is not intended to move large volumes of water long distances, and never to a manifold or on the discharge side of an engine. Limited use has been made of this hose at airtanker bases for loading. Usually this hose performs poorly when subjected to a kink test. 131 i. Garden hose Garden hose (pencil hose) is not recommended for general fire use, even though it has been used in some areas. Constructed of rubber or collapsible synthetic materials, difficulty in maintaining standard working pressures, and the uncertainty of buying premium products make this use hazardous. When garden hose is pressurized, a “scissor-like” condition occurs that increases the diameter and shortens the hose significantly. This can cause coupling failures and—when on hose reels— damage in and around the reel hub attachment and failure of some reel hubs. Available from GSA: Synthetic garden hose NSN 4210-01-167-1061. j. Suction hose, heavy duty Hard-suction draft hose is used on all engines and with all portable pumps. Under Forest Service Specification 5100-184c, the hose is made of a natural or syntheticrubber tube; a jacket consisting of cotton warp yarns or other suitable yarns interwoven with a helix or helixes of round spring-temper wire and fillers of yarn; and a synthetic-rubber outer covering. The coupled hose is designed for a hydrostaticproof pressure test of 100 psi and a vacuum of 25 inches of mercury without internal blistering, undue distortion, or leakage. Suction hoses are usually furnished in 8- and 10-foot lengths. Soft suction is now widely accepted in fire department practice where engines connect directly to hydrants. The weight savings and flexibility of these 22- to 6-inch diameters are significant factors.

Suction hose, lightweight New technology presents a lighter construction with comparable performance, capable of holding a vacuum of 25 inches of mercury and a hydrostatic proof pressure higher than the rubber draft hose, at a proof of 600 psi. It has an encapsulation treatment for enhanced abrasion resistance and the manufacturer claims an increased resistance to acids, oils, chemicals, and salt water. Weight: 12 inch 45 lb/100 foot; 2 inch 50 lb/100 foot. Available: Fire equipment suppliers (see appendix G).

Cotton-synthetic self-protecting (weeping) hoses These hoses are used as replacement for linen (unlined) hose. Cotton-synthetic hoses are lightweight, treated to prevent mildew, and designed for uniform weeping, fast drying time, and high-heat resistance. Synthetic hoses are designed for high working pressures, high temperatures, and abrasion-resistance; they may be lined for antifriction and hose-weep control to protect the hose. Written material: Fire equipment suppliers (see appendix G). Note: Unlined (linen) hose is no longer available. Refer to USDA Forest Service Wildland Fire Hose <strong>Guide</strong>, February 1997, NFES 1308. Type: Woven fabric jacket suction hose Construction and materials: Woven fabric jacket and a plastic helical reinforcement component have an encapsulation treatment. The extruded tubing is an ozone resistant, and age resistant EPDM extruded elastomer. 132
