SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable. Heating will cause rise in pressure with risk of bursting.
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. Combat fire from a sheltered position.
EXPOSURE


  • INHALATION
    		• Confusion. Cough. Dizziness. Drowsiness. Dullness. Headache. Sore throat.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
    		• Redness. Pain.
    		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

    		• Do not eat, drink, or smoke during work.
    		Rinse mouth. Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! 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. Do NOT wash away into sewer. Do NOT let this chemical enter the environment (extra personal protection: self-contained breathing apparatus).
    		Fireproof. Separated from strong oxidants. Cool. Keep in a well-ventilated room.

    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.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.
    MAK not established.


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin, and the respiratory tract. Exposure to high concentrations may result in unconsciousness.


    PHYSICAL
    PROPERTIES
    Boiling point: 101░C
    Melting point: -93░C
    Relative density (water = 1): 0.7
    Solubility in water: none
    Vapour pressure, kPa at 38░C: 10
    Relative vapour density (air = 1): 3.9
    		 Relative density of the vapour/air-mixture at 20░C (air = 1): 1.3
    Flash point: -5░C
    Auto-ignition temperature: 391░C
    Explosive limits, vol% in air: 0.8-4.8
    Octanol/water partition coefficient as log Pow: 4.55
    ENVIRONMENTAL
    DATA
         		The substance is toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in fish. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
    N O T E S
    Health effects of exposure to the substance have not been investigated.
