International Chemical Safety Cards 2-METHYLHEPTANE ICSC: 0731 C8H18 / CH3CH(CH3)CH2(CH2)3CH3 Molecular mass: 114.2 ICSC #    0731 CAS #     592-27-8 RTECS # UN #        1262 (Octanes) April 07, 1997 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Extremely flammable. NO open flames, NO sparks, and NO smoking. Powder, AFFF, foam, carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS!  •INHALATION Ventilation. Fresh air, rest.  •SKIN Dry skin. Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES 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. Do NOT induce vomiting. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Ventilation. 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. (Extra personal protection: filter respirator for organic gases and vapours). Separated from oxidants. Cool. Well closed.

International Chemical Safety Cards 2-METHYLHEPTANE ICSC: 0731 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: Upon heating, toxic fumes are formed. Reacts with oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. 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. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. PHYSICAL PROPERTIES Boiling point: 116°C Melting point: -109°C Relative density (water = 1): 0.698 Solubility in water: none Vapour pressure, kPa at 38°C: 5.3 Relative vapour density (air = 1): 3.9 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.15 Flash point: 4.4°C Explosive limits, vol% in air: 1.0-? ENVIRONMENTAL DATA N O T E S Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
