Biological limit values
No biological exposure limits noted for the ingredient(s).
Appropriate engineering
controls
Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates
should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation,
or other engineering controls to maintain airborne levels below recommended exposure limits. If
exposure limits have not been established, maintain airborne levels to an acceptable level. Eye
wash facilities and emergency shower must be available when handling this product.
Individual protection measures, such as personal protective equipment
Eye/face protection
Wear safety glasses with side shields (or goggles).
Skin protection
Hand protection
Wear protective gloves such as: Nitrile. Neoprene.
Other
Wear appropriate chemical resistant clothing.
Respiratory protection
If engineering controls are not feasible or if exposure exceeds the applicable exposure limits, use a
NIOSH-approved cartridge respirator with an organic vapor cartridge. Use a self-contained
breathing apparatus in confined spaces and for emergencies. Air monitoring is needed to
determine actual employee exposure levels.
Thermal hazards
Wear appropriate thermal protective clothing, when necessary.
General hygiene
considerations
When using do not smoke. 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. Contaminated work clothing should not
be allowed out of the workplace.
