International Chemical Safety Cards 2-HEXANOL ICSC: 0488 sec-Hexyl alcohol Butylmethylcarbinol C6H14O / CH3(CH2)3CHOHCH3 Molecular mass: 102.2 ICSC #    0488 CAS #     626-93-7 RTECS # MO8470000 UN #        2282 April 08, 1997 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. NO open flames, NO sparks, and NO smoking. Foam, alcohol-resistant foam, powder, carbon dioxide. EXPLOSION Above 41°C explosive vapour/air mixtures may be formed. Above 41°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Ventilation. Fresh air, rest. Refer for medical attention.  •SKIN Dry skin. Redness. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in earth, sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: filter respirator for organic gases and vapours). Fireproof. Separated from strong oxidants.

International Chemical Safety Cards 2-HEXANOL ICSC: 0488 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts with strong oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the skin. The substance may cause effects on the central nervous system. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. The substance may have effects on the nervous system , resulting in peripheral neuropathy. PHYSICAL PROPERTIES Boiling point: 136°C Relative density (water = 1): 0.8 Solubility in water: poor Relative vapour density (air = 1): 3.5 Flash point: 41°C Explosive limits, vol% in air: see Notes Octanol/water partition coefficient as log Pow: 1.76 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to algae. N O T E S Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C. Health effects of exposure to the substance have not been investigated adequately. Environmental effects from the substance have not been investigated adequately.
