Class 2 gas only means it's compressed and includes flammable/combustible, poisonous and inert (non-flammable, non-toxic) gases.
You would only need a fire extinguisher for flammable gas, which is Class B.
Flammable oil and gas fires are class B fires, needing a class B extinguisher.
Foam, dry powder or CO2 gas- a Class B extinguisher
A Class B fire extinguisher. Below is an article about the different types of fire extinguishers.
Class B extinguishers are used for liquid fires such as cooking oils. motor oils, gas and so on. If you don't expect toever have such a fire you probably don't need a class b extinguisher.
Electrical fire is Class C as long as the electricity is on, so use a BC or ABC extinguisher, either dry chemical, carbon dioxide gas or halogenated gas.
A Class B extinguisher. Below is an article that lists each class. Also a class A:B OR B:C each extinguisher will have a numerical value beside the B. This number indicates how many square feet of burning fluid it will extinguish by an unexperienced operator.
Because nitrogen gas bigest quantity in air.
water - removes heatsodium bicarbonate - dry chemical, removes oxygenhalons - dense gas, removes oxygencarbon dioxide - removes heat and oxygenetc.
Co2 is the main gas used. Other things are water, foam, dry powder, class d powder etc.
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.
The gas becomes a liquid inside the extinguisher. When the extinguisher is operated, the liquid changes back to a gas when released.
There is equipment that connects from the gas tank to the fire extinguisher, and is deigned to keep from overpressurizing the extinguisher. Do NOT try this without the equipment.
