3-PENTANOL ICSC: 0536 Diethyl carbinol sec-n-Amyl alcohol C5H12O / CH3CH2CHOHCH2CH3 Molecular mass: 88.2 ICSC #    0536 CAS #     584-02-1 RTECS # SA5075000 UN #        1105 EC #         603-006-00-7 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 34°C explosive vapour/air mixtures may be formed. Above 34°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. Exposure PREVENT GENERATION OF MISTS!  •Inhalation Cough. Dizziness. Drowsiness. Headache. Nausea. Sore throat. Vomiting. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •Skin Dry skin. Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •Eyes Redness. Pain. Blurred vision. Safety spectacles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •Ingestion Abdominal pain. Diarrhoea. (Further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. 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 sand or inert absorbent and remove to safe place. Personal protection: filter respirator for organic gases and vapours. Fireproof. Separated from strong oxidants.

Physical Dangers: Chemical Dangers: Reacts violently with oxidants causing fire and explosion hazard. Occupational Exposure Limits: TLV not established. Routes of Exposure: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. 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 is irritating to the eyes the skin and the respiratory tract . Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. The substance may cause effects on the central nervous system. Exposure may result in unconsciousness. Effects of Long-Term or Repeated Exposure: Repeated or prolonged contact with skin may cause dermatitis.
