On Office Fire Prevention Strategies

Learn the location of fireescape routes and how to activate the fire alarm. Participate in practice firedrills on a regular basis. Become familiar with stairway exits - elevators maynot function during a fire, or may expose passengers to heat, gas and smoke.

Through a program of scheduled inspections, unsafe conditions can be recognizedand corrected before they lead to serious injuries. Take a few moments each dayto walk through your work area. Look for items previously pointed out, such asobjects protruding into walkways, file cabinets that are weighted toward thetop or frayed electrical cords. Advise personnel in the area of the hazards andset about correcting them.

Fire Understanding

The Phenomenon of Fire
Fire is the visible heat energy being released from rapid oxidation of afuel.  Something is
'on fire' when the exothermal release of heat from the oxidation reactionreaches visible light level.

Basically, combustion takes place within two modes-flaming andflameless. The flaming mode can be viewed as a tetrahedron, with each siderepresenting one of the four basic
components of flaming combusion: fuel, heat, oxygen and uninhibited chainreaction. Here the practical emphasis is on extinguishing an existingfire.

The classic fire triangle illustrates the flameless mode, the three legsrepresenting fuel, oxygen and heat. Air provides oxygen forcombustion. The heat required for ignition varies with the characteristicsof the fuel. Fuel is any substance that will sustain combusion after theinitial application of heat to start it. Here the practical emphasis is onpreventing a fire from starting by prohibiting the formation of thetriangle.
