It is fitted with 1½” couplings to make it easily interchangeable with standard 1½” hoses. 1½” lined hose creates the least friction, and is the best at withstanding pressure. For these reasons, it is the most commonly used hose on the fireline. Lined hose is manufactured with a polyurethane inner lining. It does not sweat or weep and is therefore susceptible to heat on the fireline. It is not recommended for use inside the fire. Burning embers, sparks, or simply dragging the hose through ash will damage it. A portable water container equipped with a hand pump and back-pack straps carried on the back of fire fighters; used for applying water in suppression and mop-up operations. The duff layer is the organic material layer between the A-horizon (or uppermost soil mineral horizon) and the litter layer. The duff layer is decomposing organic material, decomposed to the point at which there is no identifiable organic materials (pine straw, leaves, twigs, etc). Econoflo is the smallest hose used by the Forest Service. It can be used with small Shindaiwa pumps or in conjunction with water thieves off 1½” mainline. It is light weight, easy to maneuver, and can withstand high levels of pressure. Econoflo is conservative on water, making it the best choice for mop-up. Unlike all the other hose, econoflo comes in 50 ft lengths and has threaded garden hose-style couplings. An engine driven pump specifically designed for use in fire suppression. A kit containing a portable forestry pump, pump tool box containing hoseline accessories, suction hose with foot valve, and gasoline container with fuel line. Foam intended for use on woody fuels. Made from hydrocarbon-based surfactants possessing excellent wetting properties and is biodegradable. Foam designed for use on flammable liquid fires. Used for applying water, wet water, or foam solution as either a solid stream or a fixed spray pattern. Medium Pressure/Medium Vol. Will replace Mark 26 as IA truck pump. Low Pressure / High Volume. Good for loading water tenders or skidder tanks. Applications: Used on IA targets or small spot fires. It is a useful pump when suppressing small excursions with small water sources. It is the primary IA pump. Performance: 1.3 hp, 4-stroke engine, Fuel consumption: 1 L/hr, Fuel capacity: .55 L integral, 40 psi, 37 gpm, Weight: 13.4 lbs. Conveys water under positive and sometimes negative pressure from the fire pumping unit to the outlet normally affixed with standardized couplings or connectors. Reduction in efficiency of a fire hose (the amount of water pressure lost) due to the resistance between the inside wall of the hose and the water flowing through the hose. The factors affecting friction loss are the velocity of the water through the hose, the roughness of the inner lining of the hose, and the diameter of the hose. The arrangement of connected lengths of fire hose and accessories on the ground beginning at the first pumping unit and ending at the point(s) of water delivery. Include a variety of pumping equipment such as couplings, valves (back check, 3 - way), nozzles, strainers, adapters, and fittings. These are the key accessories necessary on the fireline, and are stored in Provincial, Fire Centre, and Zone warehouses. High pressure/Medium volume. Completely interchangeable with Mk III and its applications. 10 hp – 2 cycle engine. Fuel consumption: 1 gal/hour. Fuel capacity: external tank. 360 psi @ shut-off. 90 gpm @ free flow. Weight: 53.5 lbs The act of extinguishing a fire after it has been brought under control. A procedure whereby the flow from two fire pumps is combined into one hose line. A self-protecting fire hose with wetting or soaking characteristics which allow the hose material to become saturated with the water when conveying water to help prevent it from burning. Unit of measure for pressure meaning Pound per Square Inch. A tank, usually collapsible, used as a reservoir in the relay of water from one fire pump to another. Low Pressure / Low Volume. Used by IA crews when flying to fires due to weight restrictions. Best used for pumping out of small water sources / stilwells. Only used when water is needed for a short duration as pressure is extremely limited. In hydraulics, the term used for the vertical distance between a fire pump and the nozzle outlet. A hose, reinforced to prevent collapse due to pressure, used to draft water into a fire pump. A term to designate the use of two or more units of the same type (e.g. fire pumps, bulldozers, crews of fire fighters) working one in front of the other to accomplish a specific fire suppression job. A type of bleeder valve designed for installation at convenient points in hose lines to permit drawing off water for filling back-pack pumps or other use without interfering with pump or nozzle operation. Water with added chemicals, called wetting agents, that increase spreading and penetrating prop A chemical that reduces the surface tension of water causing it to spread and penetrate more effectively. Very heavy (165lbs), with only marginal improvement in pressure (450 psi) over the Mk III. Can be used on the road side but not in the bush. Medium pressure/volume pump. A scaled down" version of the Mark III. More conservative with water in exchange for less pressure. Commonly used on Initial Attack pump trucks, but being phased out of wildlfire. High Pressure / Medium Volume. Used primarily by Unit Crews in expanded attack and extensive mop-up operations. Ideal for multi pump water delivery systems. The most common fire pump on the fireline. 10 hp - 2 cycle engine. Fuel consumption:1 gal/hour. Fuel capacity: External tank. 380 psi @ shut-off. 95 gpm @ free flow. Weight: 55 lbs.
