Fire Extinguishers

It is just the nomenclature used in the models of fire extinguishers of certain Chinese company. MT is used to denote their CO2 fire extiguishers.

Anything with a class "C" rating

Get another one, or use a hose reel, or get out and let the professionals take over.

put the fire extiguisher in to the fire !!

What type of fire extinguishers are commercial vehicles transporting ammunition

As long as your fire extinguisher has class k[cooking fire]labeled on the front.

To remove flammable gases

In the US, most state laws and the NFPA (national fire protection agency) require annual testing. Another view: Actually, TESTING is not required by any rules, annually, for portable fire extinguishers. TESTING is required generally at 12 years from date of manufacture. Monthly inspections and Annual INSPECTIONS are requred as well. Barry Cole Preferred Safety 303-477-8414

In the United States they can last for several years, but must be inspected annually.

Laboratory fire extinguishers shoud be located just inside each exterior door. To be as safe as possible they should probably be of the type AR-AFFF, that is Alcohol Resistant Aqueous Film Forming Foam. While these foam extinguishers are messy they extinguish the fire AND THEN they provide reflash protection. Other extinguishing agents will extinguish the fire but if all the elements of a fire are still there, oxygen fuel and temperature, then the fire can reignite. AR-AFFF prevents that and prevents the foam from degrading due to solvents which tend to be present in Laboratories.

A class D fire extinguisher is used for fighting class D fires. Class D fires are metal fires involving magnesium, potassium, sodium and sodium-potassium alloys. The class D extinguishers are mostly used in the aircraft industry, auto body shops and factories working with metal.

A water fire extinguisher with an anti-freeze charge added to it.

you should shake them to make sure that the dry powder doesn´t settle to much after awile, the powder could getting hard after years, so shake them regularly, every 1-3 months... you can al so turn them upside down and back a few times, will work better...

Aircraft fuel is often composed mainly of kerosene, making it a class B fire. Because of the volume and spread of such fires, a compressed-air foam system is often used to create a layer of foam that smothers the fire.

In the US, fire extinguishers are listed under NFPA 10, which specifies annual maintenance.

Yes?

Multi-purpose fire extinguishers, like ABC, are typically dry chemical.

Thomas J Martin had an 1872 patent for a "Fire Extinguisher." He didn't invent the portable fire extinguisher; it had been around for over 100 years before he made his contribution to fire sprinklers. His motivation is not known.

There are trade-offs with hose reels and portable extinguishers.

One advantage of a hose reel is that it has a bigger supply of water than any portable extinguisher, assuming it has been properly maintained.

More water means a person can extinguish a larger amount of fire, all things being equal (type of fire, amount of fuel, location, etc).

However, hose reels require more training than an extinguisher, cannot be moved beyond a limited space, cannot be used on all types of fires, and can cause massive amounts of damage if used improperly (flooding, water damage, broken windows, etc).

There are six classes of fires to define the type of fire, and most importantly, the type of fire extinguisher to use to put out the fire. Here are the fire classes and the types of extinguishers you should use:

Class A - Solids (wood, paper, plastic) require water, foam, dry powder, and wet chemical extinguishers.

Class B - Flammable liquids (fuel, oil, paraffin) require foam, dry powder, and CO2 gas extinguishers.

Class C - Flammable gasses (propane, methane, butane) require dry powder extinguishers.

Class D - Burning metals (aluminum, magnesium, titanium) require dry powder (M28/L2) extinguishers.

Class E - Electrical items require dry powder or CO2 gas extinguishers.

Class F - Cooking oils and fats require wet chemical extinguishers.

Class D

There are two kinds of fire extinguisher powders.

The first is monoammonium phosphate, which you find in A-B-C dry chemical extinguishers. To make it, add phosphoric acid to ammonia water until the mixture turns acidic, and the monoammonium phosphate will crystallize out of solution.

In B-C fire extinguishers you will find sodium bicarbonate. This is baking soda, and you can get that at any grocery store.
