TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking. NO contact with oxidants.
Powder, alcohol-resistant foam, water in large amounts, 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. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

  • INHALATION
    		• Cough. Dizziness. Headache. Nausea.
    		Ventilation. Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Dry skin. Redness.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
    		• Redness. Pain.
    		Safety goggles 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. Shortness of breath. Unconsciousness. Vomiting (further see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Collect leaking liquid in sealable containers. Wash away spilled liquid with plenty of water. Remove vapour with fine water spray (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Fireproof. Separated from strong oxidants, food and feedstuffs. Cool.
    		Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:
     The vapour mixes well with air, explosive mixtures are easily formed.

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

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 200 ppm; 262 mg/m3 as TWA (skin) (ACGIH 1991-1992).
    TLV (as STEL): 250 ppm; 328 mg/m3 (skin) (ACGIH 1992-1993).
    OSHA PEL: TWA 200 ppm (260 mg/m3)
    NIOSH REL: TWA 200 ppm (260 mg/m3) ST 250 ppm (325 mg/m3) skin
    NIOSH IDLH: 6000 ppm


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation and through the skin, and by ingestion.

    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:
     The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system , resulting in loss of consciousness. Exposure by ingestion may result in blindness and death. The effects may be delayed. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the central nervous system , resulting in persistant or recurring headaches and impaired vision.
