Exposure guidelines
US - California OELs: Skin designation
n-hexane (CAS 110-54-3) Can be absorbed through the skin.
US ACGIH Threshold Limit Values: Skin designation
n-hexane (CAS 110-54-3) Can be absorbed through the skin.
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 should be available when handling this product.
Appropriate engineering
controls
Individual protection measures, such as personal protective equipment
Wear safety glasses with side shields (or goggles).
Eye/face protection
Skin protection
Wear protective gloves such as: Nitrile. Polyvinyl chloride (PVC). Viton/butyl.
Hand protection
Wear appropriate chemical resistant clothing.
Other
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.
Respiratory protection
Wear appropriate thermal protective clothing, when necessary.
Thermal hazards
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.
