Is chlorodifluoromethane flammable?

Chlorodifluoromethane itself does not burn. Use water spray to reduce vapors. POISONOUS GASES ARE PRODUCED IN FIRE, including Hydrogen Chloride, Hydrogen Fluoride, Phosgene, and Carbonyl Chloride. CONTAINERS MAY EXPLODE IN FIRE.

What is chlorodifluoromethane used for?

Chlorodifluoromethane (ClCF2H), also known as Freon 22, is a highly halogenated gas that can be used as a refrigerant or propellant. But it is a threat to the ozone layer, and under the Montreal Protocol it has been nearly phased out in the United States and other developed countries.

Where does R22 come from?

In 1928, three scientists created the chlorofluorocarbon (CFC) refrigerants. These produced the world’s first non-flammable refrigerating fluids, providing safety for the air conditioners used back then. One of the compounds produced from this elemental alliance was R22, which is a hydrochlorofluorocarbon (HCFC).

Is HCFC-22 the same as R22?

HCFC-22, commonly referred to as R-22, is used as a refrigerant in many applications, including residential air conditioning (AC) systems. Starting on January 1, 2020, U.S. production and import of HCFC-22 will end, but you may continue to use HCFC-22 in your existing system for as long as necessary.

Is R22 a HCFC?

Hydrochlorofluorocarbons, or HCFCs, are chemicals that are mainly used as refrigerants. Unfortunately, releases of HCFCs deplete the Earth’s protective ozone layer and contribute to climate change. R-22 is an HCFC refrigerant that is often used in air-conditioning equipment.

Is HCFC-22 the same as R-22?

Is R-22 a CFC or HCFC?

Is R22 a CFC or HCFC?

Is HCFC-22 still used?

HCFC-22, commonly referred to as R-22, is used as a refrigerant in many applications, including residential air-conditioning (AC) systems. U.S. production and import of HCFC-22 ended on January 1, 2020, but you may continue to use HCFC-22 in your existing system for as long as necessary.

What replaces HCFC-22?

R-410A
The most common alternative to R-22 is R-410A, a non-ozone-depleting HFC refrigerant blend. R-410A is manufactured and sold under various trade names, including GENTRON AZ-20®, SUVA® 410A, and PURON®.

What color is HCFC-22 cylinder?

light green
Most are familiar with the AHRI colours, for example, of white for CFC-12, the light green of HCFC-22, the light sky blue of HFC-134a, the bright orange of the HFC blend R-404A or the rose coloured R-410A (see overleaf) as well as many others.

Is R22 CFC free?

Freon is DuPont’s commercial name for R22, a member of the chlorofluorocarbon (CFC) organic compounds that contains carbon, chlorine, hydrogen and fluorine.

Are HCFCs banned?

The use of HCFCs in new equipment was banned in 2001. From 1 January 2015 the use of ‘recycled’ and ‘reclaimed’ HCFCs to top up or service existing equipment is also banned. You can still use your old equipment, but your technician can’t do any work that involves breaking into the refrigerant circuits.

Are HCFCs still used?

New production and import of most HCFCs were phased out as of 2020. The most common HCFC in use today is HCFC-22 or R-22, a refrigerant still used in existing air conditioners and refrigeration equipment.

Are HCFCs banned in the US?

The production or import of HCFC-22 and HCFC-142b for use in new units or applications was banned in the U.S. as of January 1, 2010, although production and import for use in existing equipment is allowed through 2019.

What is the formula for HCFC-22?

SAFETY DATA SHEET HCFC-22 SAFETY DATA SHEET (93/112/EC) HCFC-22 1. IDENTIFICATION OF THE SUBSTANCE/PREPARATION AND THE COMPANY/UNDERTAKING 1.1 Identification of the preparation: HCFC-22 Synonyms : chlorodifluoromethane Formula : CHClF 2

What is CFC 22?

Growth of R-22 (CFC-22) abundance in earth’s atmosphere since year 1992. R-22 is often used as an alternative to the highly ozone-depleting CFC-11 and CFC-12, because of its relatively low ozone depletion potential of 0.055, among the lowest for chlorine -containing haloalkanes.

What is the correct shipping name for chlorodifluoromethane (R 22)?

IMDG Proper shipping name : chlorodifluoromethane (R 22) IMDG Page : 2118 UN No : 1018 Class : 2.2 EmS : 2-09 MFAG : 350 15. REGULATORY INFORMATION

Can HCFCs be used to service refrigeration and air conditioning equipment?

Since January 1, 2010, it has been illegal to use newly manufactured HCFCs to service refrigeration and air-conditioning equipment – only reclaimed and recycled HCFCs may be used. In practice this means that the gas has to be removed from the equipment before servicing and replaced afterwards, rather than refilling with new gas.
