Freon is an odorless gas; it does not smell like anything. Freon is a popular refrigerant because it is non-toxic and non-flammable. Although it dates back to 1928, Freon and its related gases are still the safest refrigerants on the market. It is also an effective aerosol propellant, but is no longer used for this purpose.Know More
Freon is a halocarbon chemical, with both chlorine and fluorine-based chemicals, sold under the trade name Freon. While it is no longer used in aerosol products due to the detrimental effect it has on the ozone layer and as a greenhouse gas, Freon is still used as a refrigerant. This is because alternate refrigerants cannot duplicate Freon's non-toxic, non-corrosive and non-flammable qualities.
Although Freon is non-toxic, large quantities of Freon in an enclosed space can cause death by asphyxiation. This is true of any gas other than oxygen, regardless of toxicity. Alternate refrigerants include ammonia, sulfur dioxide and methyl chloride, all of which are toxic. Refrigeration systems utilizing these chemicals pose a serious hazard to the people around them. In the event of a leak, toxic gases seep into the room where the refrigerator or air conditioner is located. These gases are toxic at far lower quantities than the amount of Freon needed to suffocate a human.Learn more about Atoms & Molecules
Breathing air that is contaminated with Freon can cause respiratory difficulties, organ damage and, in some cases, death. Symptoms can vary depending on the extent of the Freon exposure, but even a small amount of exposure can cause serious symptoms in humans.Full Answer >
Adding Freon to a window air conditioner involves cleaning the air conditioner, attaching a new Freon container and allowing it to intake new Freon until the container is drained. While this task is usually performed by a refrigeration mechanic, a lay person can complete it by purchasing a Freon kit.Full Answer >
Hydrogen is a chemical element that is abundant in the universe and appears as a colorless and odorless gas. It was discovered in 1766 by an English scientist named Henry Cavendish, who observed that hydrogen burns and forms water.Full Answer >
Helium is a colorless and odorless gas in its natural state. It gives off a blue neon color when burned. When an electric current runs through it, helium is a pale peach to orange color.Full Answer >
