What are fire extinguishers be used for?
FIRE extinguishers are used to put out fire.
What is in fire extinguishers that puts out fire?
Fire extinguishers commonly contain water under pressure, compressed carbon dioxide, foam, or specialized dry chemicals, depending on the type of fire they are designed to put out.
Can lung cancer be caused by inhalation of dry powder fire extinguishers?
no they do not. they contain carbon dioxide, potassium bromide, and chalk. nothing in that is harmful.
Is Metal Gear Solid portable ops plus an expansion pack?
Yes and no. It does not contain the original MGS portable ops, and you can take soldiers from the original and add them to it, but you can play it without the original game.
Does a car battery have any gas in it?
An auto battery does emit hydrogen gas when it is being charged or discharged but it does not contain gas per se.
What chemicals can be found inside a fire extinguisher?
The content inside fire extinguisher, besides a pick-up tube and a valve, is made up of several commercially recognized and approved suppressant materials such as: water, water with additives (such as foams like AFFF, FFFP, etc.) Dry Chemicals such as sodium bicarbonate (baking soda) or potassium bicarbonate and other salts in combination, gasses like CO2 and streaming gasses like Halon, FM 200, FE 36, etc. For specific fire class usage such as class D (metals) and class K (cooking media, i.e., vegetable oils and fats) extinguishers may contain wet chemical compounds of potassium salt for K ratings and Dry Chemical formulations that contain mica and other salts that may suppress or control flammable metals (class D).
Is a fire extinguisher round?
Most fire extinguishers contain a powder with a pressurized propellant, or sometimes just a pressurized gas, and occasionally a liquid under pressure.Round containers are best for pressurized containers because they retain their shape under pressure. Most fire extinguishers are cylindrical shaped with either concave or convex ends.
What gas is insise a fire extinguisher?
Many different types of fire extinguishers exist and many different gases are used. A water extinguisher may contain pressurized air. Other types use carbon dioxide or compressed nitrogen. There are also halogenated extinguishers containing proprietary mixtures of fire-suppression gases.
Do most portable radios contain a headphone jack?
Almost all portable radios have a headphone jack. Even radios that are ten years old or more have a headphone jack so its pretty much standard.
What state of matter is inside a fire extinguisher?
There are many different types of extinguishers, but many of them contain solid (dry chemical), liquid (water or foam), or compressed gas (CO2 or nitrogen).
Does fire extinguisher contain hydrogen?
Not elemental hydrogen, no. That would not work in a fire extinguisher as hydrogen is highly flammable. Some fire extinguishers do use water, however, which is a hydrogen compound.
What is in antique fire extinguishers?
Much like modern ones, antique fire extinguishers used a range of extinguishing agents. Carbon tetrachloride, water, and carbon dioxide were most common. Carbon tetrachloride is a liquid that was used in glass grenade-type extinguishers or pumped metal extinguishers. While it is quite effective at putting out fires, it is extremely poisonous, and should be disposed of by professionals. This material fights fires by disrupting the chemical chain reaction. When exposed to high temperatures, it can produce phosgene, an insidious poison gas used during both world wars. Halon extinguishers replaced this type, and have, in turn, been replaced by newer clean agents less harmful to the ozone layer. Water extinguishers were either operated by a hand pump or propelled using a soda-acid system. In the latter, a glass vial containing sulfuric acid was suspended over baking soda. The vial was shattered, spilled, or unplugged by a plunger or other mechanism when the extinguisher was needed. Instructions on this type typically started by telling you to turn the extinguisher upside-down and strike the top against the floor. The sulfuric acid reacted with the baking soda much as vinegar would, only faster and more violently. The resulting carbon-dioxide gas would propel the water, typically 2.5 gallons, out through the hose. This type was removed from service by 1982 because the reaction would often not last long enough to expel all the water and the containers had an unfortunate tendency to explode when used. The similar air pressurized water extinguishers have replaced this type. Carbon dioxide extinguishers remain in use and are easily identified by the horn used to direct the extinguishing agent and the lack of a pressure gauge. These extinguishers contain liquefied carbon dioxide. While carbon dioxide gas mixed with dry ice is what comes out when you use the extinguisher, internally, the agent is a liquid under those pressures. Because carbon dioxide extinguishers in service, it is possible to have tested and refilled an extinguisher of this type. While an extinguisher has an expected service life of 25 years, they are often overbuilt and underused. I recently had serviced two carbon dioxide extinguishers that were manufactured in 1960, and used from then until 1992. Interestingly, even though they were not entirely full, they retained significant pressure even after having been stored for 18 years. Some fire extinguishers are simply filled with compressed Nitrogen, which choke out combustion because it cannot survive in a pure Nitrogen atmosphere. The Simplex-Grinnell UN 1066 is such an extinguisher.
