Personal
Protection:
Eye/Face:
Safety glasses. Chemical goggles. Face shield.
Respirator:
If strong
vapor or mist is present, use organic vapor chemical cartridge respirator,
self-contained or supplied air
respirator. For vessel entry use self-contained or supplied air respirator
with full facepiece.
Protective
Clothing:
Where
splash or mist potential exists, wear chemical worker's goggles and butyl
or nitrile rubber gloves. Other
protective equipment such as aprons, rubber boots, face shield, or rubber
suit may be needed. Eye wash stations
and safety showers should be readily accessible near use areas.
Other:
Do not
smoke in areas of storage or use. Employees who handle dimethyl sulfide should
wash their hands
