TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly 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. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


  • INHALATION

    		• Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest.
  • SKIN

    		• 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.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer.
    		Fireproof. Separated from strong oxidants.

    UN Hazard Class: 3
    UN Packing Group: II

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:
     The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.

    CHEMICAL DANGERS:
     Reacts violently with oxidants causing fire and explosion hazard. Attacks plastic.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as hexane isomers): 500 ppm; 1760 mg/m3 (ACGIH 1993-1994).


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its vapour.

    INHALATION RISK:
     A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20░C.

    EFFECTS OF SHORT-TERM EXPOSURE:

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point: 63.3░C
    Melting point: -118░C
    Relative density (water = 1): 0.66
    Solubility in water: none
    Vapour pressure, kPa at 20░C: 20.5
    		 Relative vapour density (air = 1): 2.97
    Flash point: <20░C
    Auto-ignition temperature: 278░C
    Explosive limits, vol% in air: 1.2-7.0
