The Phaseout of Ozone Depleting Chemicals for the Precision Cleaning of Spaceflight Hardware at Hamilton Standard Space systems International
Over the past two years, Hamilton Standard Space Systems International (HSSSI) has had an active program underway to identify, evaluate and design a non-ozone depleting chemical (ODC) based precision cleaning process for spaceflight hardware. This paper outlines the various elements and findings of this program which has culminated in the design of a non-ODC based precision cleaning process. Th...
متن کاملOzone-Depleting Substances: Alternatives
Surrounding the earth at a height of about 25 kilometers is the stratosphere, rich in ozone, which prevents the sun’s harmful ultraviolet (UV-B) rays from reaching the earth. UV-B rays have an adverse effect on all living organisms, including marine life, crops, animals and birds, and humans. In humans, UV-B is known to affect the immune system; to cause skin cancer, eye damage, and cataracts; ...
متن کاملThe increasing threat to stratospheric ozone from dichloromethane
It is well established that anthropogenic chlorine-containing chemicals contribute to ozone layer depletion. The successful implementation of the Montreal Protocol has led to reductions in the atmospheric concentration of many ozone-depleting gases, such as chlorofluorocarbons. As a consequence, stratospheric chlorine levels are declining and ozone is projected to return to levels observed pre-...
متن کامل1 3 . Stratospheric ozone depletion
The ozone layer in the stratosphere absorbs a large part of the harmful UV-radiation coming from the sun. In the natural situation ozone is continuously being formed and destroyed. However, a number of man-made chemicals that contain fluorine, bromine and chlorine groups, called Ozone Depleting Substances (ODS), can greatly increase the rate of destruction, leading to a reduction in the thickne...

Key findings !" Atmospheric concentrations of ozone depleting substances have decreased as a result of the effectiveness of the Montreal Protocol. !" The global (60°S–60°N) ozone concentration is projected to return to pre-1980 levels by around the middle of the 21st century. !" Antarctic ozone levels are projected to return to pre-1980 levels around 2060–75, which is 10–25 years later than pre...
