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

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.

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.
