INDUSTRIAL FIRE PROTECTION
No industry needs to be reminded of
the catastrophic consequences resulting from in-workplace fires. However,
such fires are in many cases avoidable. Hindsight too often has revealed
flaws in what was other wise considered to be an effective fire protection
system.
Fire results from the ignition of a
substance in a supply of oxygen The substance involved vaporizes when ignited.
If a sufficient degree of vaporization results, such that the ratio of
oxygen to vapor reaches a certain level, burning will continue even after
the ignition source is removed. Each material has a minimum temperature
at which it will burn of its own accord. This is called its "ignition temperature.
This temperature is affected by variables such as the size and shape of
the place where it occurs; the amount of oxygen present, the type of ignition
source, etc. Different materials vaporize at different temperatures - some
require the addition of heat to vaporize, while others will vaporize at
room temperature. These latter substances are referred to as flammable
materials (i.e. gasoline) and require special handling.
The three requirements for fire are:
Oxygen Fuel and an Ignition Source. The elimination of any one of
the three will control or prevent fire. Oxygen is the most difficult of
the three to eliminate, since it is part of the surrounding air. It is,
however, possible to limit the amount of oxygen, for example by storing
oil rags in closed metal cans. The heat and rate of vaporization may cause
the spontaneous ignition of the clothes but a closed container prevents
replenishment of the oxygen and so the flames will be smothered. There
are many ways of limiting the potential fuel for fires...
1. GOOD
HOUSEKEEPING
is among the most important. Trash
should never be allowed to accumulate in the workplace since it can provide
a ready fuel source for welding sparks, cigarettes etc.
Dispose of all flammable wastes quickly and efficiently. Flammable scrap wiping rags or rubbish go in metal containers provided. Gasoline, kerosene, oil, or other flammable liquids go in special containers provided - never pour down drains or sewers.
2.
ALWAYS OBEY
SMOKING REGULATIONS.
These are made for the protection of you and of others. Usually
the "no smoking" sign indicates that there are flammable materials or conditions
in the area. You cannot see the vapors but lighting a match could involve
you in a fire.
3.
KNOW WHERE AND HOW TO TURN IN A FIRE ALARM.
Know where the fire extinguishers
are kept in your area and know what type fire they are meant for. Know
the fire exit you should use in an emergency. Help emergency fire brigades,
but do not get in their way.
4. CHANGE YOUR CLOTHES RIGHT AWAY IF THEY GET SOAKED WITH 0IL, KEROSENE; NAPHTHA OR OTHER FLAMMABLE LIQUIDS. Not only will changing prevent skin troubles, but it will prevent a bad burn if the retained vapor catches on fire.
