Fire Extinguishers
Fire extinguishers are used in homes, schools, businesses and boats as a way to put out a small fire. Fire extinguishers come in many types for different purposes, including portable or fixed systems. This category relates to the science, origins, operation, selection and standards for fire extinguishers.

What type of fire extinguishers used for gas fire?
An "ABC" extinguisher will put out a gasoline fire but I recommend an extinguisher that uses Halon. Halon will not corrode an engines internals like the ABC type will. Halon deprives the fire of oxygen to extinguish the fire. A lot of race car drivers use the same type systems on their cars in case of fires. Addendum: Halon has been out of production since the early 1990's and availability is very limited. There are various other "clean" agents on the market that have been developed as halon replacements, but they can be quite expensive. An alternative to these expensive products, although a powder and quite messy, is regular "BC" chemical. Unlike the "ABC" product "BC" does not melt a stick to metal, instead it simply smothers the fire and is easier to clean off than ABC - although it too is corrosive.
In what year did T Marshall invent the fire extinguisher?
Actually it was a type of fire standpipe and sprinkler in which water pressure from a reservoir and pump pushes water up pipes and into a building to a valve that can be opened to make the water spray out of nozzles.
US Patent 125,063, issued March 26, 1872 to Thomas J. Martin [sic], of Dowagiac, Cass County, Michigan.
There were no US patents at ALL issued on October 26, 1872. They were only issued on Tuesdays and the 26th was a Saturday.
What fire extinguisher would you use on a Chip pan?
A tight-fitting lid, a fire blanket, a box of sodium bicarbonate or salt may work, but a type ABC fire extinguisher would be best. Turn off the electric source as well.
Under NO circumstances use a water-type (often class A) on a hot oil fire or on an energized electrical device.
Class C fires are fires that involve energized electrical equipment?
Class C fires involve energized electrical equipment, such as appliances, wiring, and power tools. These fires pose unique hazards because using water or foam extinguishers can conduct electricity, increasing the risk of shock. Instead, Class C fires should be extinguished with non-conductive agents like dry chemical or carbon dioxide extinguishers. Once the electrical source is de-energized, the fire can then be classified as a different type (like Class A or B) if it continues to burn.
As a general rule you should not attempt to fight a fire if it is spreading rapidly?
As a general rule, no. Leave that to the firefighters. If you are in a house that is on fire, try get out as fast as possible and leave your belonging behind!
That depends on what the fire is burning. You need to be more specific in order to get a viable answer.
What is the foam inside a fire extinguisher made of?
They can use one of three gases. In a foam extinguisher, it's usually compressed air which is very cheap--the price is just the electricity required to make it--and works well. They can also use carbon dioxide or nitrogen.
What are the consequences of fire blanket extinguisher?
The fire isn't put out properly, although incorrect use of a fire blanket would be quite challenging as one only has to cover a pan fire or wrap someone in one.
How can you remove fire extinguisher residue?
Get you a can of engine degreaser from any auto parts store or even walmart in the automotive dept... this works really good just spray the stuff on and let it set for a couple mins and just spray off with a garden hose...
How do you put out a grease pan fire?
To put out a grease pan fire carefully shake baking soda on it. Not baking powder, baking soda. Bicarbonate of soda, the same stuff used to keep refrigerators smelling fresh.
Another suggestion...
If you have a lid that fits onto the frying pan, or whatever the pot or pan is that contains the grease, place the lid as tightly/closely as possible over the top. A grease fire should be suffocated that way. If you don't have a lid, try using another pan a little larger than the one that's on fire.
Never ever pour water onto a grease fire.
If you can't do any of the above, leave the room immediately, alert any other people in the house and call the fire brigade.
Another answer:
One of the most important pieces of kitchen equipment is a good, thick, pure-cotton, large (around 140cm x 70cm - 55in x 30in) bath towel, kept on a rack in a central area.
In the case of a pan fire, a grill (broiler) fire, or similar emergencies the towel can easily be thrown over the fire source at arms' length. It's highly dangerous to attempt placing a lid over a burning pan or other fire source once flames are beginning to rise; apart from time lost in finding an appropriate lid, even if you do find one the fire can flare up in a micro-second and you won't be able to control it, call emergency, or even warn the household, if you've just had your face and hands severely burned because you're standing over a fiery pan trying to put a lid on it.
Remember, firefighters wear protective gear and observe strict safety rules to prevent this kind of thing happening: emergency service personnel are no good to anybody if they injure themselves in the first moments of response. Amateur firefighters facing a domestic fire need to understand why this is so, and avoid placing themselves in danger.
The versatile thick towel shouldn't ever be used to wipe surfaces or greasy utensils; it should be kept clean.
It might seem to some an extravagance to put a good bath towel in the kitchen. It isn't. Once you've had it there for a week you'll wonder how you ever managed without it. I have two on rails fixed to work areas, near the ovens and sink, and near the fridge and stovetop; one of their great uses is they can be quickly flipped up onto the bench to take hot or wet dishes, or to drain washed fruit and vegetables, glassware, and so on. I clip mine to the rails so they stay in place, but a quick tug releases them. They're great for drying hands after washing up, and always to hand in case of a large water spill; you just throw a towel over the liquid so nobody's going to slip before you can mop it up. And we've all had those kitchen moments when we need to quickly move a pan that's hotter than expected and the oven gloves or trivet aren't immediately to hand: this is where the kitchen towel is a great friend.
How does fire impact on water?
water is a liquid and fire is a smoke/solid water stops it i really dont know how to answer that
Turn the extiguisher upside down, and give it a shake.
What category is suitable for a fire extinguisher?
There are several categories of fire extinguishers. It depends on where the extinguisher is likely to be used and on what type of fire is to be expected. For example: a soda and water extinguisher is commonly used for general type fires. But, due to the risk of being electrocuted, a soda and water extinguisher would be dangerous to use round high voltage electrical equipment - so a carbon dioxide extinguisher would be used instead. On oil fires, a foam extinguisher would be best, as a soda water extinguisher would simply spread the area of the oil fire, and even increase the intensity of the flames, while the foam would smother the flames, cutting off the oxygen to feed the fire.
What chemical in fire extinguishers destroys ozone?
See "What is causing the depletion of the ozone layer?" in the "Related questions" section below.
In general what are dry chemical fire works with extinguishers designed to do?
Fire needs three things to burn: fuel, oxygen, and heat. Take away one or more of those three things in sufficient quantities, and the fire can no longer burn.
.
A dry chemical fire extinguisher sprays a noncombustible, air resistant layer of foam designed to cover the fire's fuel source. When the fuel source (wood, oil, cloth, etc.) is completely and properly smothered, the expelled dry chemical foam isolates the fuel from the surrounding air, and thereby starves the fire of the oxygen it needs to burn.
What is the stored psi of a Fire extinguisher?
A 15 pound portable CO2 fire extinguisher is pressurized to 850psia at 700F. The cylinders are designed to withstand pressures up to to 3000psi. The safety release disk ruptures at a pressure between 2,650 and 3,000 psi.
Why nitrogen gas is not used as fire extinguisher agent?
While nitrogen is an inert gas and capable of putting fire out it is very impractical to use as a fire suppression agent. All products used in portable fire extinguishers can be seen when discharged either as a liquid or a powder so you can see where it is going. All of these products are also heavier than air so they will always tend to sink downward towards the base of the flames (at least for a short while). Nitrogen cannot be seen and is not heavier than air making it a very poor choice.
please answer that can nitrogen is used as a fire extinguishing element, or tell me another elements for this purpose please answer that can nitrogen is used as a fire extinguishing element, or tell me another elements for this purpose
What are the reasons why fire extinguisher explode?
apparently, the answer is somehow yes. the fire extinguisher in the basement somehow exploded and the top of it where the trigger thing is went straight through the sheetrock of the ceiling!that had to be one strong strong explosion if it broke through the sheetrock.
the question is: what made it explode? the thing probably was last serviced over 10-15 years ago!
Do fire extinguishers use oxygen?
No. Fire is a chemical reaction between oxygen and a flammable material. Adding extra oxygen speeds up the reaction, making the fire burn even hotter and making it easier for the fire to spread.
