Is Freon toxic to breathe?
Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it can cut off vital oxygen to your cells and lungs. Limited exposure — for example, a spill on your skin or breathing near an open container — is only mildly harmful . However, you should try to avoid all contact with these types of chemicals.
Are CFCs safe?
Whereas CFCs are safe to use in most applications and are inert in the lower atmosphere, they do undergo significant reaction in the upper atmosphere or stratosphere. ... Chlorine released from CFCs destroys ozone in catalytic reactions where 100,000 molecules of ozone can be destroyed per chlorine atom.

Does China still use CFCs?
China, which joined the Montreal Protocol in 1991 and said it successfully ended the industrial use of CFCs in 2007, questioned the conclusions of the EIA study. Nevertheless, the government said in mid-2019 it would boost monitoring efforts and impose penalties on companies caught illegally producing the chemical.
What gas is destroying the ozone layer?
Ozone depleting substances are chemicals that destroy the earth’s protective ozone layer. They include: chlorofluorocarbons (CFCs) halons .
Is CFC 11 a greenhouse gas?
According to the NOAA Annual Greenhouse Gas Index (AGGI), the total radiative forcing by all long-lived greenhouse gases (carbon dioxide (CO2), methane (CO4), nitrous oxide (N2O), CFC-12, CFC-11, and various lesser gases) has increased by 26% since 1990.
Are CFCs still used in India?
Under the Montreal Protocol, to which India became a signatory in 1992, CFCs have to phased out in India and the developing world by 2010 and there are indications this deadline will be advanced by 4 years.
