Toxic Hazard ..but it's ozone friendly!

Gina McCarthy, President Barack Obama's nominee to lead the Environmental Protection Agency, will have tough questions to answer about the approval of a potentially deadly vehicle air-conditioning refrigerant. It's highly inflammable giving off a gas, hydrogen fluoride, with a toxicity is comparable to hydrogen cyanide.

An EPA sub-department, the Office of Air and Radiation, approved HOF-1234yf.

McCarthy said that the chemical 'helps fight climate change and ozone depletion.'

It is highly poisonous, disfiguring and extremely hazardous to humans. But that's OK, because it's harmless to Ozone!

Kirk Hogan comments

Those of you unfamiliar with hydrogen fluoride may know it as hydrofluoric acid: It is so dangerous that when it is used in industrial applications, such as etched glass, the work must be done under a hood with a fan and filters to trap the vapors. It must be stored in wax-lined containers; it 'eats' glass. Fluorine is the most chemically active of ALL the elements and it rapidly reacts with many other elements...and is worse for your health than the chlorine gas the Germans released in WW I at Ypres...'

All this begs the question, of course, of whether the ozone hole is "caused by" the use of synthetic chlorfluorocarbons previously used in vehicle aircon systems and fridges, etc.

Here is the conventional environmentalist wisdom.

chlorofluorocarbon

A class of synthetic chemicals that are odourless, non-toxic, non-flammable, and chemically inert. The first CFC was synthesized in 1892, but no use was found for it until the 1920s. Their stability and apparently harmless properties made CFCs popular as propellants in aerosol cans, as refrigerants in refrigerators and air conditioners, as degreasing agents, and in the manufacture of foam packaging. They are now known to be partly responsible for the destruction of the ozone layer. In 1987, an international agreement called the Montréal Protocol was established; it was one of the first global environmental treaties and it banned the use of chemicals responsible for ozone damage, such as CFCs in aerosols and refrigerants.

When CFCs are released into the atmosphere, they drift up slowly into the stratosphere, where, under the influence of ultraviolet radiation from the Sun, they react with ozone (O3) to form free chlorine (Cl) atoms and molecular oxygen (O2), thereby destroying the ozone layer which protects the Earth's surface from the Sun's harmful ultraviolet rays. The chlorine liberated during ozone breakdown can react with still more ozone, making the CFCs particularly dangerous to the environment. CFCs can remain in the atmosphere for more than a hundred years. Replacements for CFCs are being developed, and research into safe methods for destroying existing CFCs is being carried out.

Since the ozone hole is still there maybe blaming the manmade CFCs for it was wrong?
