Choosing a gouging method - The Fabricator
Gouging with air on carbon steel can leave a thin, dissolved, nitrogen-rich layer on the gouged surface. In certain welding situations, this can cause microporosity. Normally, this is a problem only in very high-quality welding situations and can be removed with light grinding on the surface or by using inert gas as the plasma gouging gas.

Ozone: Ozone is an important component of the stratosphere where it absorbs harmful UV radiation before it reaches the ground. This ozone layer may be in danger because of the slow diffusion of chlorofluorocarbons (freons) into the stratosphere. The reactions that are thought to occur there are shown below. CF 3 Cl h CF 3 + Cl Cl + O 3
Ozone Generator Hazards - InterNACHI®
Ozone is the principal element of the ozone layer, which traps the sun's heat and is essential to life on Earth. Unlike breathable, stable oxygen molecules, which are composed of two oxygen atoms, ozone is composed of three. The third oxygen atom in ozone can easily detach from the ozone molecule and reattach to other substances, altering ...

Ozone - Canada.ca
Ozone (O 3) is a gas that exists in the upper atmosphere and at ground level. It can be good or bad for your health depending on its location. Ozone is a naturally occurring gas that is present in the upper atmosphere. It is necessary for life on earth. The ozone layer keeps the planet warm and protects us from the sun's ultraviolet rays.

pheric ozone may delay recovery of the ozone layer by 15–20 years (5). Third, depletion of stratospheric ozone and global warming due to the build-up of greenhouse gases interact to alter UVR related effects on health. In a warmer world, patterns of personal exposure to solar radiation (e.g. sun-bathing
R32 vs R410A vs R22 vs R290 (Air Conditioner Refrigerants)
The Making of CFCs including R12 is discontinued in 1994 as the CFCs are one of the main reasons for greenhouse gas effect and depletion of ozone layer. Hydrochlorofluorocarbons (HCFCs) R-22 is the most common refrigerant that is used in the air conditioners. In the late 1990s, the CFCs were replaced by Hydrochlorofluorocarbons.
