FIRE FIGHTING
FIRE Combustible under specific conditions. Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION Risk of fire and explosion on contact with powdered metals: see Chemical Dangers.


EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Burning sensation. Cough. Laboured breathing. Shortness of breath. Unconsciousness.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Pain. Redness. Blisters.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
    		• Pain. Redness. Severe deep burns.
    		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. Confusion. Diarrhoea. Headache (further see Inhalation).


    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Consult an expert! Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Separated from strong oxidants, strong bases, powdered metals, food and feedstuffs: see Chemical Dangers. Dry. Keep in the dark. Ventilation along the floor.
    		Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive fumes, hydrogen bromide (see ICSC # 0282) and bromine (see ICSC # 0107. The substance decomposes slowly under influence of light and moisture producing corrosive hydrogen bromide. Reacts vigorously with powdered aluminium or magnesium, metals such as sodium, potassium and calcium, strong bases and strong oxidants, causing fire and explosion hazard. Attacks fats, rubber, some plastics and coatings.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.
    OSHA PEL: TWA 20 ppm C 30 ppm 50 ppm 5-minute maximum peak
    NIOSH REL: Ca TWA 0.045 ppm C 0.13 ppm 15-minute See Appendix A
    NIOSH IDLH: Potential occupational carcinogen 100 ppm


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

    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. The substance may cause effects on the central nervous system , resulting in lowering of consciousness.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Lungs may be affected by repeated or prolonged exposure causing bronchitis. The substance may have effects on the liver and kidneys. This substance is probably carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
