Which are two major efforts to save Ozone layer?
Two major efforts to save the Ozone layer are the Montreal Protocol, an international treaty aimed at phasing out the production and consumption of ozone-depleting substances, and public awareness campaigns to encourage individuals and businesses to use ozone-friendly products and practices.
What are some items that equals at destroy the ozone?
Some items that can harm the ozone layer include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl chloroform, and carbon tetrachloride. These substances are often found in refrigerants, solvents, foam-blowing agents, and fire extinguishers, and can lead to ozone depletion when released into the atmosphere.
What chemicals are believed to have caused destruction in the ozone layer of the stratosphere?
Chlorofluorocarbons (CFCs) and halons are the main chemicals responsible for destroying the ozone layer in the stratosphere. These chemicals were commonly used in refrigerants, propellants, and fire extinguishers before their harmful effects on the ozone layer were discovered. efforts have been made to limit their production and use through international agreements like the Montreal Protocol.
What are some hazards to the ozone layer?
The man-made gases of CFCs (chlorofluorocarbons). Chlorines and bromines from these gases stay in the atmosphere for years, destroying ozone molecules. This allows the sun's dangerous ultra violet (UV) radiation to reach earth, causing human cancers and damage to crops.
What human made chemical in particular destroys the ozone layer?
Chlorofluorocarbons (CFCs) are human-made chemicals that are known to destroy the ozone layer. When released into the atmosphere, they break down ozone molecules, depleting the ozone layer that protects Earth from harmful UV radiation. CFCs are commonly found in refrigerants, aerosol propellants, and foam-blowing agents.
What chemical in fire extinguishers destroys ozone?
See "What is causing the depletion of the ozone layer?" in the "Related questions" section below.
What is halon fire extinguisher used for?
Class A fire extinguishers - used for fires caused by "ordinary combustibles" aka paper, wood, plastic, cardboard, etc.Class B fire extinguishers - used for fires caused by flammable liquids such as gasoline and oil.Class C fire extinguishers - used for electrical firesClass D fire extinguishers - used for fires caused by explosive or flammable metals (most commonly found in laboratoriesClass K fire extinguishers - used for fires found in commercial kitchens

Ozone layer depletion cfc's in global warmng?
Global Warming has nothing to do with the Ozone layer. Ozone is a chemical, O3 ,that stops most of the UV radiation from the sum from getting to the earth's surface. Chloro-fluoro carbons- CFC's are chemicals that were used in cooling systems and complex fire extinguishers, as well as aerosols. When scientists did research in the 1970's etc, they worked out that CFC's, such as Freon, chlorotrifluoromethane, CClF3, break ozone into oxygen and "oxygen radicals", that react with the CFC. This creates a hole in the ozone layer. A lack of ozone doesn't affect global warming. Instead, the CFC's themselves are potent greenhouse gases that contribute to the greenhouse effect and global warming.

What are dry chemical fire extinguishers to do?
They form a barrier on the surface of the burning substance - which melts to form an airtight layer - starving the fire of oxygen. Smother the fire
Is nitrogen in fire extinguishers?
Nitrogen can be used in fire extinguishers as gas propellant.
What are fire extinguishers be used for?
FIRE extinguishers are used to put out fire.
Where can you get fire extinguishers recharged?
You can get fire extinguishers recharged at fire equipment companies, some hardware stores, and fire departments.
Do all boats need fire extinguishers?
No, there are boats that do not need any fire extinguishers.
