Common Fire Hazards

Fire safety is the arrangement of practices planned to diminish the obliteration created by flame. Fire safety measures incorporate those that are expected to avoid ignition of an uncontrolled fire, and those that are utilized to restrain the improvement and impacts of a fire after it begins.

Some common fire hazards are:

• Kitchen fires from unattended cooking, such as frying, broiling, and simmering
• Electrical systems that are overloaded, resulting in hot wiring or connections, or failed components
• Combustible storage areas with insufficient protection
• Combustibles near equipment that generates heat, flame, or sparks
• Candles and other open flames
• Smoking (Cigarettes, cigars, pipes, lighters, etc.)
• Equipment that generates heat and utilizes combustible materials
• Flammable liquids and aerosols
• Flammable solvents (and rags soaked with solvent) placed in enclosed trash cans
• Fireplace chimneys not properly or regularly cleaned
• Cooking appliances - stoves, ovens
• Heating appliances - fireplaces, wood burning stoves, furnaces, boilers, portable heaters
• Household appliances - clothes dryers, curling irons, hair dryers, refrigerators, freezers
• Chimneys that concentrate creosote
• Electrical wiring in poor condition
• Leaking Batteries
• Personal ignition sources - matches, lighters
• Electronic and electrical equipment
• Exterior cooking equipment - barbecue

Types of Fire Extinguishers

It is important to know what type of extinguisher you are using. Using the wrong type of extinguisher for the wrong type of fire can be life-threatening.

Most common Types of Fire Extinguishers:

Water extinguishers or APW extinguishers (air-pressurized water) are suitable for class A fires only. Never use a water extinguisher on grease fires, electrical fires or class D fires - the flames will spread and make the fire bigger! Water extinguishers are filled with water and are typically pressurized with air. Again - water extinguishers can be very dangerous in the wrong type of situation. Only fight the fire if you're certain it contains ordinary combustible materials only.

Dry chemical extinguishers come in a variety of types and are suitable for a combination of class A, B and C fires. These are filled with foam or powder and pressurized with nitrogen. o BC - This is the regular type of dry chemical extinguisher. It is filled with sodium bicarbonate or potassium bicarbonate. The BC variety leaves a mildly corrosive residue which must be cleaned immediately to prevent any damage to materials. o ABC - This is the multipurpose dry chemical extinguisher. The ABC type is filled with monoammonium phosphate, a yellow powder that leaves a sticky residue that may be damaging to electrical appliances such as a computer.

Dry chemical extinguishers have an advantage over CO2 extinguishers since they leave a nonflammable substance on the extinguished material, reducing the likelihood of re-ignition.

Carbon Dioxide (CO2) extinguishers are used for class B and C fires. CO2 extinguishers contain carbon dioxide, a non-flammable gas, and are highly pressurized. The pressure is so great that it is not uncommon for bits of dry ice to shoot out the nozzle. They don't work very well on class A fires because they may not be able to displace enough oxygen to put the fire out, causing it to re-ignite. 

CO2 extinguishers have an advantage over dry chemical extinguishers since they don't leave a harmful residue - a good choice for an electrical fire on a computer or other favorite electronic device such as a stereo or TV.

USING A FIRE EXTINGUISHER

USING A FIRE EXTINGUISHER

P - Pull the Pin at the top of the extinguisher. The pin releases a locking mechanism
and will allow you to discharge the extinguisher.

A - Aim at the base of the fire, not the flames. This is important - in order to put out
the fire, you must extinguish the fuel.

S - Squeeze the lever slowly. This will release the extinguishing agent in the
extinguisher. If the handle is released, the discharge will stop.

S - Sweep from side to side. Using a sweeping motion, move the fire extinguisher
back and forth until the fire is completely out. Operate the extinguisher from a safe
distance, several feet away, and then move towards the fire once it starts to
diminish. Be sure to read the instructions on your fire extinguisher - different fire
extinguishers recommend operating them from different distances.

Remember: Aim at the base of the fire, not at the flames !

Learn About Fire Safety - FIRE PREVENTION

• Try not to leave electrical machines unattended
• Switch off electric machines after use and remove the socket. It is fire safe practice. 
• Try not to over-burden electrical circuit; it may cause short circuit and a fire
• Don't keep electric wiring hanging, secure appropriately. 
• Try not to utilize light the in the event of force disappointment. Client battery worked tourches. 
• Smoke just in the Smoking Zone, use non-flammable ashtrays for storing lit smoking material 
• Use ashtray while Smoking 
• Keep matches, saltines, lighters far from the kids. 
• Try not to permit kids to play with fireworks. 

• Do not light fire works near the structures . 
• Close the windows and openings appropriately to counteract entrance of lit flying saltines. 
• Try not to leave lit oil lights, agarbattis or candles on the floor or close ignitable material. Put them off before resigning to bed. 
• Do not store scrap/combustible material in and around the building; dispose it regularly.
• Keep L.P.G. Stove/Segree/Burner on raised non-ignitable stage. 
• Turn off both the L.P.G. gas barrel valve and burner handle of the gas segree/cooking extent and so on when not being used in the wake of cooking. 
• Ventilate the whole room if L.P.G. chamber is spilling and don't switch on/off any of the electric switches the room in . Supplant L.P.G. supply tube intermittently or as and when prompted by Mechanic. 
• In the event that L.P.G. barrel is spilling 

                - Close the principle barrel valve.
                - Ventilate the whole room.
                - Do not work electric switch.

Classification of fires

Classification of fires as per ISI 2190/1979

Class 'A' Fires

Fire including ignitable material, for example, wood, paper, fabric, elastic, plastic requiring the warmth retaining impacts of water, water arrangements.

Class 'B' Fires

This sort of fire includes combustible or ignitable fluids oils, petroleum items and comparable materials for annihilation, a covering impact is vital.

Class 'C' Fires

Which includes flammable gasses, substance under weight including liquified gasses. Here it is important to weaken the smoldering gasses at quick rate with an idle gas , Dry compound powder or co 2.

Class 'D' Fires

Fire including ignitable metals, for example, Sodium, magnesium, zinc, potassium. These blazing metal respond with water and water containing operators. These fire requires exceptional media to quench, for example, carbon-di-oxide unique dry chemical powder.
