"Freon" is a trademark name of DuPont for a series of HFC and CFC refrigerants which they manufactured - other companies manufactured and continue to manufacture the same refrigerants, but cannot use the name Freon for their product. Some of the refrigerants marketed under the name Freon are flammable, and some are not. The CFC refrigerants will almost certainly be flammable - the HFC refrigerants may or may not be.
Freon is a gas at room temperature and a liquid when cooled or compressed. Freon gas is colorless, non-flammable and relatively odorless. Some Freons have an ether-like odor.
Freon is not one specific type of refrigerant - the name is actually a trademark of DuPont, and is applied to a whole line of CFC and HFC refrigerants manufactured by them. Most of these refrigerants are not flammable.
No.
One non-flammable gas used as a refrigerant is carbon dioxide (CO2). It is commonly used in commercial and industrial refrigeration systems as an environmentally-friendly alternative to synthetic refrigerants that contribute to global warming.
The simplest colourless, flammable gas beginning with 'e', is 'ethane'.
Nitrogen gas is not in itself flammable, and does not have an auto ignition temperature.
R 134 is freon gas. In small amounts, the exposure to freon gas is not dangerous. In larger amounts, freon can cause respiratory issues.
Hydrogen gas is the lightest gas and extremely 'flammable', rather called explosive.
A label for a flammable liquid typically depicts a flame over a liquid, while a label for a flammable gas usually includes a flame or gas cylinder symbol. The label for a flammable liquid may also indicate the specific type of liquid, while the label for a flammable gas may specify the type of gas.
Flammable gas refers to any gas that can ignite and burn easily under normal conditions, while combustible gas is a subset of flammable gas and refers specifically to gases that can ignite and burn in the presence of oxygen. In other words, all combustible gases are flammable, but not all flammable gases are necessarily combustible.
Flammable gas refers to gases that can ignite and burn when exposed to a flame or spark. Toxic gas, on the other hand, refers to gases that can be harmful or even lethal if inhaled or absorbed into the body. Essentially, flammable gases pose a fire hazard, while toxic gases pose a health hazard.
Oxygen is a byproduct of photosynthesis and is also a flammable gas.
