EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Above 74°C explosive vapour/air mixtures may be formed.
Above 74°C use a closed system, ventilation.
In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water. Combat fire from a sheltered position.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Convulsions. Cough. Dizziness. Headache. Laboured breathing. Nausea. Shortness of breath. Unconsciousness. Vomiting. Irregular heartbeat, tightness in the chest.
    		Closed system and ventilation.
    		Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Redness. Pain (See Inhalation).
    		Protective gloves. Protective clothing.
    		Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
    		• Redness. Pain.
    		Face shield, 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 cramps. Burning sensation. Convulsions. Unconsciousness. See Notes (see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Provision to contain effluent from fire extinguishing. Separated from strong bases, acids, water, food and feedstuffs. Well closed. Keep in a well-ventilated room.
    		Airtight. Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:
     The vapour is heavier than air.

    CHEMICAL DANGERS:
     The substance decomposes rapidly on heating or on contact with bases or water, producing highly toxic and flammable hydrogen cyanide (see ICSC # 0492), and acetone (see ICSC # 0087). Reacts violently with acids and oxidants causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 4.7 ppm; 5 mg/m3 (ceiling values) as CN (skin) (ACGIH 1997).
    OSHA PEL: none
    NIOSH REL: C 1 ppm (4 mg/m3) 15-minute
    NIOSH IDLH: No data


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation, 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 cardiovascular system and central nervous system , resulting in asphyxia, cardiac disorders, convulsions, cyanosis and respiratory failure. Exposure may result in death. Medical observation is indicated. See Notes.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the central nervous system and thyroid , resulting in impaired functions.
    PHYSICAL
    PROPERTIES
    Boiling point: 95°C
    Melting point: -19°C
    Relative density (water = 1): 0.93
    Solubility in water: freely soluble, but decomposes in water
    		 Vapour pressure, kPa at 20°C: 3.0
    Relative vapour density (air = 1): 2.93
    Flash point: 74°C c.c.
    Explosive limits, vol% in air: 2.2-12
    ENVIRONMENTAL
    DATA
         		The substance is very toxic to aquatic organisms. Avoid release to the environment in circumstances different to normal use.
    N O T E S
    Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Hazard and toxicity of this substance is due to its major metabolite - hydrogen cyanide (see ISCS # 0492).
