Stratospheric Ozone Depletion During the last 100 years, refrigerants such as; CFCs,
HCFCs, HFCs, and HFOs have dramatically changed our lifestyles. Little did we know
that the use and release of these compounds into the atmosphere would have
devastating effects on the Earth's environment. One of these effects is far removed from
the Earth's surface, in the Stratosphere. Located between 7 and 30 miles above the
Earth's surface, the Stratosphere contains the Ozone layer. The Ozone layer is the
earth's security blanket. The Ozone layer serves two important functions. Ozone
protects us from harmful Ultra Violet Radiation and helps to maintain stable Earth
temperatures. Depletion of Ozone in the Stratosphere causes: Increased eye disease
Skin cancer Crop loss Deforestation Reduced marine life Increased ground level ozone
An Ozone molecule consists of three oxygen atoms (O3). When CFC's are released into
the atmosphere, t - ANSWER2nd page

Montreal Protocol The Montreal Protocol is an international agreement (treaty)
regulating the production and use of CFC's, HCFC's, halons, methyl chloroform, and
carbon tetrachloride entered into force in mid 1989. This landmark agreement initially
called for a production and consumption freeze. It currently calls for a stepwise
reduction and eventual production phase out of various ozone depleting substances.
The production phase-out of CFC's was completed on December 31, 1995. At present,
HFC-134a is used by most new car manufacturers as a replacement for CFC-12 and
older vehicles may be converted to use HFC-134a by following proper retrofit
procedures. Although HFC-134a is considered ozone friendly, it is not without
environmental impact. It has been found to be a greenhouse gas and contributes to the
problems of global warming. Effective November 15, 1995, HFC-134a must be
recovered. Penalty Section 609 of the Fe - ANSWERpage 3
