In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Reddening of the face. Salivation. Disturbance of movements. Convulsions. Cough. Dizziness. Headache. Laboured breathing. Unconsciousness. Loss of memory. Shock.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Redness (Further see Inhalation).
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap. 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
    		• Burning sensation (further see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Consult an expert! 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. Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Separated from strong bases, food and feedstuffs, oxidants and metals. Keep in the dark. Ventilation along the floor. Store only if stabilized.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. TURNS YELLOW ON EXPOSURE TO LIGHT AND AIR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic and corrosive fumes including hydrogen bromide and bromine. The substance is a weak acid. Reacts violently with oxidants, bases in powdered form and is corrosive to most metals. Reacts with alkaline metals, powdered aluminium, zinc and magnesium and acetone under basic conditions, causing fire and explosion hazard. Attacks some forms of plastic, rubber and coating.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 0.5 ppm; 5.2 mg/m3 (skin) (ACGIH 1993-1993).
    OSHA PEL: TWA 0.5 ppm (5 mg/m3) skin
    NIOSH REL: TWA 0.5 ppm (5 mg/m3) skin
    NIOSH IDLH: 850 ppm


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

    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:
     Tear drawing. The substance irritates the respiratory tract, the eyes and the skin. The substance may cause effects on the central nervous system and liver , resulting in impaired functions.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the central nervous system and liver , resulting in tissue lesions.

    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to water organisms. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
    N O T E S
    Depending on the degree of exposure, periodic medical examination is indicated. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Do NOT take working clothes home.
