Biological limit values
No biological exposure limits noted for the ingredient(s).
Appropriate engineering
controls
Provide sufficient ventilation for operations causing dust formation. Observe occupational
exposure limits and minimize the risk of exposure.
Individual protection measures, such as personal protective equipment
Eye/face protection
Wear approved safety goggles.
Skin protection
Hand protection
It is a good industrial hygiene practice to minimize skin contact. For prolonged or repeated skin
contact use suitable protective gloves.
Other
Normal work clothing (long sleeved shirts and long pants) is recommended.
Respiratory protection
If engineering controls do not maintain airborne concentrations below recommended exposure
limits (where applicable) or to an acceptable level (in countries where exposure limits have not
been established), an approved respirator must be worn. Use a NIOSH/MSHA approved air
purifying respirator as needed to control exposure. Consult with respirator manufacturer to
determine respirator selection, use, and limitations. Use positive pressure, air-supplied respirator
for uncontrolled releases or when air purifying respirator limitations may be exceeded. Follow
respirator protection program requirements (OSHA 1910.134 and ANSI Z88.2) for all respirator
use. Observe any medical surveillance requirements.
Thermal hazards
None.
General hygiene
considerations
Always observe good personal hygiene measures, such as washing after handling the material
and before eating, drinking, and/or smoking. Routinely wash work clothing and protective
equipment to remove contaminants. Observe any medical surveillance requirements.
