These gases can include butane, methane and propane. Extra care must be taken with this fire type as there is more potential for an explosion, and therefore gases like this must be stored properly in sealed containers.
As mentioned, you must take very special care with class C fires due to the explosion risk. The gas supply should be switched off, if possible, and then only dry powder fire extinguishers have efficacy against gas fires. If combustible metals build up in one area, they can ignite to form a class D or metal fire. Culprits are usually metal shavings or powdered metals, as opposed to solid blocks of metal.
As such, class D fires are only likely to break out in laboratories or industrial settings which handle these materials. Common in both domestic and commercial kitchens, class F fires are caused primarily by cooking oil catching alight. They are also known as chip-pan fires.
Never use water on a class F fire as this could strengthen the spread. Instead, use wet chemical fire extinguishers, created specifically to tackle cooking oil fires. Faulty, malfunctioning or overloaded electrical components, such as circuits or wiring, have the potential to cause an electrical fire.
This can occur in homes and commercial settings alike. Make sure everything is cold before leaving it. The embers ash and logs should be cold enough to touch before you abandon it entirely. No smoke should be coming from the fire and you should be able to detect no heat. Let it sit and check it after a few minutes to be sure.
Method 3. Look at what resources are available to contain the fire. If you are near a source of water from a pressurized system, and have sufficient hoses available, use them to extinguish minor fires, and wet the potential fuel in the immediate area. Use a tool to create a "fire break" if no water is available. Dig a shallow trench around the perimeter of the blaze, or scrape potential fuel away, exposing as much bare earth as possible. Concentrate on the area "downwind" of the flames, since the wind will push the blaze in that direction.
A farm tractor with a disk, a bulldozer, or other equipment can quickly establish a sizable fire break. Try to extinguish the fire with water. Use buckets, pots, or other containers to carry water to the blaze if no other fire fighting equipment is available, and a stream or pond, or other source of water is nearby. If you're close enough to the brush to use a hose, take advantage of the water as soon as possible.
Try to control the burn by wetting the ground in front of the direction the fire might be traveling. If it's blowing in a particular direction, watch the wind to anticipate it's motion and cut it off at the pass.
Be prepared to evacuate the area if danger reaches an unacceptable level. If you must flee a fire, choose a path which can be traversed quickly and easily, away from the path of the fire. If smoke and heat becomes intense, cover your mouth with your shirt, preferably wetting it first. Call the fire department. If your leaf pile has gotten slightly out of control, that's one thing, but a serious brush fire needs to be handled immediately by professionals.
Use your judgment and call the fire department as soon as a brush fire escapes a manageable area or size. Method 4. Always keep a good quality fire extinguisher in your house.
Consider having a few in easy to reach locations and make sure everyone in your household knows how to use them. Keep one in the basement, one in the kitchen, and one elsewhere in the house, like near the sleeping quarters. They're good for several years, but get them tested out regularly and recharged to make sure they'll be ready when you need them. Keep your fire alarms in good working order. Check your fire alarms every month to make sure the batteries are in good condition and change them out regularly.
Having the right warning system in place can give important extra minutes that can be the difference between an inconvenience and a disaster. Maintain your electrical appliances regularly. Never overload outlets or power strips with chords. Avoid plugging in more chords than an outlet can handle to eliminate the possibility of dangerous electrical fires. Regularly unplug unused appliances to avoid needless circuits. Go to source Use space heaters wisely.
Keep flammable clothing and other substances clear of space heaters and other devices that might catch things on fire. Be careful with candles. More than one-third of home fires begin with candles. Please remember not to leave candles unattended and make sure they're far enough from drapes and other cloth that could start a fire. Always put them out safely and make sure candles are entirely out before you leave them unattended.
Consider using battery or electric-operated heaters in lieu of open flame candles. You can get all the aromatic benefits of burning candles without the risk of fire. Electrical fires are especially dangerous because your first instinct - to reach for a bucket of water to douse the flames - will actually cause the flames to spread, since water conducts electricity.
To put out an electrical fire, you should:. The natural gas that powers many stovetops, fireplaces and heating sources can overheat the surrounding structures like a fireplace mantel and set them on fire.
If you smell a gas leak, you should call the gas company immediately and turn off the gas at its source. Liquid gas fires like gasoline can be put out by smothering with a blanket. If that doesn't work, or if there's no blanket nearby, use a fire extinguisher. Water is ineffective in putting out a gas fire and can increase the chance of injury, as the heat from the fire will boil the water almost immediately, putting you at risk for steam burns. Deep fried turkeys, counter top fryers, even a griddle of sizzling bacon can all set the stage for a kitchen grease fire.
Grease fires occur when oil or grease collect in the cooking container and get hot enough to ignite. Like electrical fires, grease fires are extremely dangerous - not only do they burn very hot, but because grease is liquid it can easily splash on to other flammable surfaces or yourself.
Throwing water on a grease fire only increases the danger. The water will sink to the bottom of the pot, where it will become super-heated and eventually explode, sending scalding grease and water everywhere. Warm, cozy and inviting, wood burning fireplaces are the focal point of any room they are in.
But if maintained or extinguished improperly or left unattended, the fire can quickly rage out of control. If you are faced with a fireplace fire, don't treat it like a campfire and douse it with water.
Not only will this create a mess and send ash flying throughout the room, it can also damage the fireplace. Instead, follow these steps:. You shouldn't see any flames or feel any heat coming from a the fireplace if the fire was properly extinguished. Vehicle fires occur every seconds and cause more than deaths and 1, injuries per year.
If you're faced with a vehicle fire, stay calm and get off the road as quickly and safely as possible - you don't want to risk causing an accident. If you can't get off the road, put on your hazard lights, stop the car and get out. Then, take these steps :. If your summer plans include a wilderness campout, take Smokey the Bear's advice and learn how to prevent forest fires.
The secret? Keep the flames to a manageable size, never leave it unattended and, when you've gotten your fill of roasted marshmallows and hot dogs on a stick, follow these steps to extinguish your campfire properly:. Fuel can be anything that is combustible, such as wood, petroleum and spirits, and a number of gases.
Solid fuels must reach a critical temperature in order to ignite, while many liquids release flammable vapours even when cold.
Gases are the most hazardous and temperamental state, and can combust instantaneously. The principles of fire extinction state that a fire will be put out if one of the three elements are removed, and this can be done using three different approaches, as detailed below….
Removing the heat is one of the most effective methods of fire extinction available, which is why water is a popular extinguishing material. The fire will go out so long as the heat generated by the fire is less than that which is absorbed by the water.
