TB 43-0135
CHAPTER 1
INTRODUCTION
Section I. General Information
1-1.
SCOPE
The stratospheric ozone layer protects the earth from dangerous ultraviolet-B (UV-B) radiation. Depletion of stratospheric
ozone allows more UV-B radiation to penetrate to the earth's surface. Increased radiation, in turn, has been linked to
higher incidence of certain skin cancers and cataracts, suppression of the human immune system, damage to crops and
aquatic organisms, and increased formation of ground-level ozone. In order to encourage movement away from ozone-
depleting substances (ODSs), substitutes that offer lower overall risks to human health and the environment have been
identified by the Environmental Protection Agency (EPA).
This technical bulletin lists the currently identified substitutes for ODSs used with Communications-Electronics equipment.
In addition, the TB provides generalized instructions for the use of the approved substitutes in maintenance procedures. It
also lists Class I ODSs, which will no longer be procured after 1995, and Class II ODSs, some of which will no longer be
manufactured after 1999. Provided for information are various obsolete WARNINGS, CAUTIONS and NOTES and their
substitutes.
