Environmental Considerations The attempt to take the necessary actions to protect human health and the environment against adverse effects resulting or likely to result from human activities which can modify the ozone layer has led to:
The Montreal Protocol on Substances that Deplete the Ozone Layer as adjusted and/or amended in London 1990 - Copenhagen 1992 - Vienna 1995 - Montreal 1997 - Beijing 1999 web site: http://www.unep.org/ozone

Health problems associated with low concentrations of oxygen in the ambient air, can generally be summarised as: 16% can lead to impaired judgment and breathing 14% can lead to faulty judgement and rapid fatigue 6% can lead to breathing difficulties and be fatal in minutes It must however be understood that the above conditions are dependent on the length of exposure time.
