OSHA Regulatory Status: this material is classified as hazardous under OSHA regulations.
Emergency Overview:
n-Hexane is a simple hydrocarbon and can cause irritation and central nervous system depression at high concentrations. n-Hexane
vapors are irritating to the eyes and respiratory system. Use only with adequate ventilation. Contents under pressure. Avoid heat and
flames. Cylinder temperature should not exceed 125OF (52OC). Protect containers from physical damage. This mixture is nonÂflammable.

Synergistic Effects
None Reported
Health Effects:
Carcinogenicity: NTP: No IARC: No OSHA: No
Eye Effects:
Irritation may occur. Contact with rapidly expanding gas near the point of release may cause frostbite.
Skin Effects:
Contact with rapidly expanding gas near the point of release may cause frostbite with redness, skin color change to gray or white, and
blistering. Liquid hexane is an irritant to the skin and can be absorbed through the skin.
Ingestion Effects:
Ingestion is unlikely.
Inhalation Effects:
Gas mixture contains sufficient oxygen to support life (at least 99.4% of mix is air). Inhalation of high concentrations of hexane
vapors may depress the central nervous system causing dizziness, difficulty in walking, respiratory tract irritation, numbness of the
extremities and may result in eventual respiratory paralysis at very high concentrations. Symptoms may include headaches, weakness
in the fingers and toes, blurred vision, appetite and weight loss, nausea, and throat irritation.
Chronic Effects:
Repeated exposure to n-hexane may damage the nervous system causing peripheral neuropathy often characterized by weakness and
numbness in the arms and legs. Symptoms generally disappear within a few months after exposure stops.
Medical Conditions Aggravated by Exposure:
Any type of paresthesia may be aggravated by hexane exposure.
Potential Environmental Effects:
Administration of hexane up to 100 ppm for 96 hours in artificial seawater (@ 8 0C) caused no mortalities in young Coho salmon.

4 = Severe Hazard
Ratings were assigned in accordance with Compressed Gas Association (CGA) guidelines as published in CGA Pamphlet P-19-2004,
CGA recommended Hazard Ratings for Compressed Gases, 2nd Edition.
Eyes:
None required for gas. If frostbite is suspected, flush eyes with cool water for 15 minutes and obtain immediate medical attention.
Skin:
None required for gas. For frostbite, immerse skin in lukewarm water. DO NOT USE HOT WATER. Obtain medical attention.
