WARNINGS AND CAUTIONS
Section I. Current Notices
B-1.
OBSOLETE WARNINGS
The following WARNINGS, which have traditionally appeared in TMs 11, are obsolete.
WARNING
Compressed air is dangerous and can cause serious bodily harm if protective means or
methods are not observed to prevent a chip or particle (of whatever size) from being
blown into the eyes or unbroken skin of the operator or other personnel. Compressed
air shall not be used for cleaning purposes except where reduced to less than 30
pounds per square inch gauge (30 psig) and then only with effective chip guarding and
personnel protective equipment (industrial safety glasses and full faceshield). DO NOT
use compressed air to dry parts when TRICHLOROTRIFLUOROETHANE has been
used.
WARNING
Adequate ventilation should be provided while using TRICHLOROTRIFLUOROETHANE.
Avoid prolonged breathing of vapor The solvent should not be used near heat or flame;
the
products
of
decomposition
are
toxic
and
irritating.
Since
TRICHLOROTRIFLUOROETHANE dissolves natural oils, avoid prolonged contact with
skin. The use of chemical gloves (solvent resistant), chemical splash goggles and full
faceshield are required when using TRICHLOROTRIFLUOROETHANE. DO NOT use
compressed air to dry parts when TRICHLOROTRIFLUOROETHANE has been used.
TRICHLOROTRIFLUOROETHANE is an ozone-depleting substance.
B-2.
REPLACEMENT WARNING
The following WARNING replace the two WARNINGS listed above.
WARNING
Compressed air is dangerous and can cause serious bodily harm if protective means or
methods are not observed to prevent a chip or particle (of whatever size) from being
blown into the eyes or unbroken skin of the operator or other personnel. Compressed air
shall not be used for cleaning purposes except where reduced to less than 30 pounds per
square inch gauge (30 psig) and then only with effective chip guarding and personnel
protective equipment (industrial safety glasses and full faceshield).  DO NOT use
compressed air to dry parts when solvent cleaners have been used.
WARNING
TRICHLOROTRIFLUOROETHANE, TRICHLOROETHANE and similar chemical solvents
will no longer be used for ordinary cleaning of equipment. These substances threaten
public health and the environment by destroying ozone in the earth's upper atmosphere.
Suitable non-hazardous cleaning materials will be used instead, such as a clean cloth,
water and mild detergent or an approved substitute solvent, such as isopropyl alcohol.
