You can find them in fridges and in aerosols,
CFC's can go up into the ozone layer and damage it if these things are not properly disposed of
Many countries have phased out the use of chlorofluorocarbons (CFCs) due to their harmful effects on the ozone layer. Some developing countries may still use them in limited quantities for specific applications where alternatives are not readily available. Overall, the use of CFCs has decreased significantly worldwide in compliance with the Montreal Protocol.
No, CFCs are not used in tubeless tires. CFCs (Chlorofluorocarbons) are ozone-depleting substances that have been phased out due to environmental concerns. Tubeless tires rely on a sealing system that does not require CFCs for their operation.
Although the production and release of CFCs have significantly decreased due to the Montreal Protocol, a global agreement to protect the ozone layer, they can remain in the atmosphere for many years. The impact of CFCs on the ozone layer is still observed, but it is gradually decreasing. Efforts to phase out CFCs and switch to ozone-friendly alternatives have been successful in mitigating their effects.
Probably not. There may be some small companies in developing countries still using CFCs but all major countries have phased them out by the end of last century. Hairsprays have other chemicals which may not be good for the atmosphere either. We may have to wait and see.
After discovering the harmful effects of CFCs on the atmosphere, scientists developed substitutes such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) to replace CFCs in various applications like refrigeration and air conditioning. These alternatives have lower ozone-depleting potential and are less harmful to the environment than CFCs. Additionally, advancements in technology have led to the development of more environmentally friendly alternatives like natural refrigerants such as ammonia, carbon dioxide, and hydrocarbons.
no cfc's are not in use anymore because they damage the enviroment.

Chlorofluorocarbons (CFCs) were once used as propellants in aerosol cans, but since the Montreal Protocol was agreed to in 1989, they have been replaced in nearly every country. This is because of the negative effects CFCs have on Earth's ozone layer. Aerosols are now propelled by mixtures of volatile hydrocarbons, typically propane, n-butane and isobutane. Food sprays use nitrous oxide and carbon dioxide.

In order to save the ozone layer,we have to curb the use of CFCs. These CFcs are the ones that help in the destruction of ozone.
Yes. People developed chemicals such as CFCs (Chlorofluorocarbons) for use in refrigerators and as a propellant gas in aerosols. These CFCs rose high into the atmosphere and caused damage to the ozone layer. the use of CFCs has since been banned and the ozone layer is slowly recovering. Hopefully.

Refrigeration and air conditioning: CFCs are used as refrigerants in air conditioners and refrigerators, releasing them into the atmosphere when these appliances are serviced or disposed of improperly. Foam production: CFCs are used in the production of foam materials for insulation and packaging, which can release the gases when the foam degrades or is disposed of. Solvent use: CFCs have been used as solvents in various industries such as cleaning and degreasing, leading to their release into the atmosphere during use or disposal. Fire suppression systems: Some fire suppression systems still use CFCs as extinguishing agents, causing them to be released into the atmosphere during firefighting activities.
Yes, the dangers to which he his colleagues drew attention were recognised, the use of CFCs has been greatly reduced and there are still laws governing their use in various jurisdictions. Please see his article on wikipedia.
Countries agreed at the Montreal Conference to ban the use of chlorofluorocarbons (CFCs). It was clear to everyone that CFCs were damaging the ozone layer and this could lead to severe damage to humans. This ban has been the most successful international intervention ever. No CFCs are now being released and scientists hope the ozone level will have self-repaired by 2060 (CFCs hang about in the atmosphere for up to 75 years!).
Old fridges typically use chlorofluorocarbons (CFCs) as the refrigerant gas. These gases have been phased out due to their harmful effects on the ozone layer.
