Introduction About Prevention Of Fire :
Fire is a chemical reaction that requires three elements to be present for the reaction to take place and continue. The three elements are: · Heat, or an ignition source · Fuel · Oxygen.To know more about Prevention of Fire,watch Prevention of Fire Video to learn more .
Prevention Of Fire :
Fire prevention requires segregating the three elements of the fire triangle. In practice, a method to achieve that goal is to post and enforce no smoking signs around flammable liquids and gases and have fire watches on all work involving torch applied materials of a minimum of two hours after the last torch is turned off. Flammable liquids that are extremely viscous, or difficult to pour, like singleply adhesive, can be left in their original shipping containers. Similarly, O.S.H.A allows the use of original containers of flammable liquids that are in quantities of one gallon or less. Liquefied petroleum gas (L.P gas) is used widely in the roofing industry to heat kettles and torches. Because L.P gas is a compressed gas, fairly large quantities can be stored in relatively small containers. As a point of reference, L.P gas expands at a ratio of 270-to-1. This means that one liquid drop of L.P gas would expand to a gas state 270 times greater in volume. L.P gas collects in low lying areas because its vapor density is heavier than air. Employees should be warned that if they suspect a leak in a cylinder, they must not use fire to attempt to find the hole. Instead, they are to use soapy water and look for bubbles. Employees should not attempt to extinguish fires involving L.P gas. If an L.P gas fire breaks out, employees should evacuate the area immediately and call the fire department. Fighting an L.P gas fire requires specialized training that only the fire department can provide. Employee attempts to extinguish the fire could create larger hazards.
