Tackling a Fire at HomeIf you do not have a fire extinguisher at home, here are some tips to tackle fires:
Kitchen Fire: If a vessel with oil or any cooking item catches fire• DO NOT POUR WATER. • SWITCH OFF the stove• COVER THE TUMBLER/PAN WITH A LID so oxygen is cut off.
When you pour water, oil will float on it aggravating the fire and hot liquid/flames might splash on you.
If you cannot cover the tumbler with a lid• Take all the BAKING SODA you can and splash it on the fire.
IF IN DOUBT – GET OUT! Dial 101
Tackling a Fire at HomeElectrical Fire: When any electrical equipment starts to give out sparks /smoke, immediately SWITCH OFF THE MAINS /SWITCH. DO NOT POUR WATER ON ELECTRICAL EQUIPMENT.
If the mains/ switch itself is on fire, wear rubber slippers/boots, wrap a newspaper in the form of a tube, and BEAT THE AREA OF MAINS/SWITCH ON FIRE. This is called “beating the fire”. Imagine you holding a newspaper and hitting someone. Same thing.
Do not mess around with electricity. Its deadly.
Once any switch/wiring is on fire & is extinguished, call an electrician to check the integrity of the remaining circuit.
IF IN DOUBT – GET OUT! Dial 101
Fire Safety at HomeIf you smell LPG in your house• Turn off the gas and open all the windows. • DO NOT turn off/turn on any electrical appliances/switch.• If possible, take the cylinder out of the house. Carefully.• Call your gas supplier for further assistance.
If you are cooking something in the kitchen• Do not leave it unattended.• Have proper ventilation• Ensure Kitchen Exhaust fans/chimneys are cleaned regularly to remove any residual grease. This can easily catch fire.• Use protective clothing /tools to handle hot utensils.
Do not overload electrical sockets. One socket = one equipment
Response in a Fire Emergency
ABSENCE OF BODY IS BETTER
PRESENCE OF MIND IS GOOD
Response in a Fire Emergency• FIRST: GET OUT OF THE BUILDING. THEN CALL FIRE BRIGADE. Gases in smoke can disorient an adult in under a minute.
• Do not assume anyone else has already called the fire department. If you get a chance to call, do so.
• Calling your friends & family may not be of immediate help. It can wait. Call them once you are safe.
• Stay calm when you call fire brigade. Give the information they request like precise floor no, street, landmarks, intensity of fire.
• Your safety & well being is more important than posting on twitter /facebook. No, seriously. Be alert, save your phone battery. Tweet when you are out of the crisis safely.
Response in a Fire EmergencyIn Your OfficeEvery office has to comply with the legal requirement to have an emergency response protocol. Get in touch with your office management & ask for company policy on emergencies.
After you read this, walk around your office premises and make note of the emergency exit paths and doors. They should NEVER be blocked or locked. Your mind will not work normally during crisis. Presence of mind & Knowledge helps.
Actively participate in any safety training arranged by your office. NEVER HESTITATE to ask questions or demand for an emergency plan. After all, its is a matter of your safety & life.
Response in a Fire Emergency
• Sound the fire alarm. SHOUT “FIRE FIRE FIRE FIRE”• Fight the fire if you are competent and if safe to do so• Evacuate as per normal fire procedure• Leave the building immediately. Use the nearest exit• DO NOT use elevators/lifts. Always use emergency stairs.• Walk quickly but don’t run. STAY CALM. • Close doors behind you (if no one else is evacuating)• Do not delay your exit trying to collect your belongings• Assemble at the fire assembly point. Report to fire officers• Do not go home. Rescuers need to ensure that all occupants are safely out of the building & are accounted for.• Do not return inside the building until told to do so
When You notice a fire:
In Your Office
Response in a Fire Emergency
Feel the door with the back of your hand (more nerve endings, more sensitive to touch). If the door feels warm to the touch, DO NOT attempt to open it. Stay in the room.
If you are stuck in a room & there is a fire outside the door
• Stuff the cracks around the door with wet towels, rags, bedding and cover vents to keep smoke out. Fire is attracted to oxygen & a room not on fire has more oxygen than a room on fire.• Call fire brigade & tell them exactly where you are located. Do this even if you can see fire brigade on the street below.• Wait at a window and signal for help with a flashlight or by waving a bright cloth.• If possible, open the window at the top and bottom, but do not break it, you may need to close the window if smoke rushes in.• Be patient. Rescuing all the occupants of a high-rise building can take several hours.
Response in a Fire EmergencyIf you are stuck in a room & there is a fire outside the door
• If the door is not warm to the touch, attempt to open the door, brace your body against the door while staying low to the floor and slowly open it a crack. What you are doing is checking for the presence of smoke or fire in the hallway.• If there is no smoke in the hallway or stairwells, follow your building’s evacuation plan.• Cover your nose & mouth with a wet cloth.• Always crawl or keep your head as low as possible, since smoke is lighter and will be high above the ground. Inhaling smoke is as dangerous as getting stuck in a fire.• If you don’t hear the building’s fire alarm, pull the nearest fire alarm “pull station” while exiting the floor.• If you encounter heavy smoke or flames on your way out, immediately return to your office.
Response in a Fire EmergencyIf Your clothes catch on fire use STOP DROP & ROLL TECHNIQUE
• DO NOT run. It will spread the fire across your body.• Stop where you are, drop to the ground & roll back & forth• Spread across flat on the ground. DO NOT curl up.• Roll from your back to your front repeatedly till fire is squashed.• After the flames are extinguished, get up & remove the clothing.• Burnt clothing can burn you. This is no time to be shy. If you have to remove all clothes, just get naked.
