Relay operations is a pumping technique used to tackle insufficient fire ground water supply. Factors influencing the implementation of relay operations are grouped in phases like design, setup and shutdown of relay operations.
Use the dump line to allow water flow from source engine till the discharge of all the air from supply line and engage pump by adjusting throttle…
Attacks pumpers are hydraulic devices designed specifically to solve complex problems in hydraulics during firefighting and are constructed to apply water to control fire. Attack pumpers are also used earlier as mini pumpers and required limited staffing to handle fire fighting .It is ideal for attack pumpers to possess fire hose and desired pre-connected lines in order to support the attacks at the fire scene at a faster pace and maneuver the fire.
This has led to the application of technology in the fire service so as to effectively deal with the disasters (Edwards, 2004). In spite of the increased demand for technology in the fire service, it is still considered important for a firefighter to understand basic mathematics.
The identified areas which are protected through a manual fire protection are ideally accessible with respect to smoke, toxic combustion products, heat, and also with radiation.
voltage. During operational rounds, hired technicians of companies check the ammeters for current flow to the electrical systems.
Concrete is one of the most significant ingredients in construction to improve the strength of the building and to support the structure. It is composed of cement, slag cement, fly ash, aggregate (limestone, gravel, sand, granite, etc.) water and certain chemical additives.
For all intents and purposes hydraulics (Greek: Hydro meaning water; Aulos meaning pipe), as it relates to the fire service is the study of the behaviour of water in motion or at rest.
Water is the main fire-extinguishing medium used by the fire service because it is relatively cheap and readily available.
(Couvillon, 2006, p33)
If a length of hose is of a diameter of less than 2 1/ 2 inch. We can determine its equivalent length in 2 ½ inch hose by dividing the length of the hose by a conversion factor. (Sylvia and Casey, 2002, p
