Fire extinguishers are to be kept in areas easily accessible to employees. Only approved fire extinguishers <br />are to be used. They must have an inspection tag attached. Extinguishers are to be maintained in a fully <br />charged, ready to operate state. Extinguishers are to be inspected before each use and documented annually. <br />Training is provided to all employees who use or may use fire extinguishers. <br />■ NEVER put yourself or others a risk while attempting to extinguish an incipient fire. <br />■ DO NOT USE any fire hoses larger than 1-3/4", unless fully trained as an industrial firefighter. <br />■ NEVER attempt to extinguish a pressurized -fuel fed fire. <br />■ DO NOT direct a fire nozzle with a straight stream at any type of LPG fire. This action could extinguish the fire, <br />producing an LPG vapor cloud capable of detonation. <br />■ DO NOT USE fire monitors as the force can damage small equipment and certain high chrome alloy <br />equipment cannot have water applied as cracking could occur. <br />■ DO NOT APPLY water to any acid or caustic release as it can cause a violent reaction. Additionally, low <br />concentration acids or caustics become extremely corrosive, causing an increasing leak condition. <br />In the Event of a Fire: <br />• Remain calm <br />• Only extinguish a fire when it is clearly within your abilities and the equipment available <br />■ Know the location of the nearest alarm and how to activate the emergency system <br />Know the evacuation routes and collection points <br />If the fire cannot be extinguished, leave the area immediately and report to your evacuation area <br />■ Await further instructions from the Incident Commander, or designated responsible personnel <br />Basic Fire Science: <br />• The combination of fuel, heat, oxygen equals the well-known fire triangle. To understand fire better, <br />a fourth factor is added, a molecular chain reaction. This is due to the fact that fire results from a series <br />of reactions in which complicated molecules "crack" into easily oxidized fragments. Disruption of this <br />chain, along with the removal of fuel, heat or oxygen, is recognized as a method of fire extinguishment <br />through the use of dry chemical extinguishers. <br />Fuel <br />Fuel Heat Molecular Chain Reaction <br />Oxygen <br />Oxygen <br />37 <br />Heat <br />
