NO open flames. AFFF, alcohol-resistant foam, dry powder, carbon dioxide. EXPLOSION Above 70°C explosive vapour/air mixtures may be formed. Above 70°C use a closed system, ventilation. EXPOSURE  •INHALATION Cough. Headache. Ventilation. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Safety spectacles. 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 sand or inert absorbent and remove to safe place. Ventilation along the floor.

International Chemical Safety Cards 4-METHYLCYCLOHEXANOL ICSC: 0296 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour and by ingestion. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is slightly irritating to the eyes and the skin . Exposure at high levels of the vapour may result in irritation of the eyes and upper respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. PHYSICAL PROPERTIES Boiling point: 173°C Melting point: see Notes Relative density (water = 1): 0.92 Solubility in water: poor Relative vapour density (air = 1): 3.9 Flash point: 70°C c.c. Auto-ignition temperature: 295°C Octanol/water partition coefficient as log Pow: 1.79 ENVIRONMENTAL DATA N O T E S This substance exists in two geometrical isomers (cis and trans).
