SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames. NO contact with water.
Foam, powder, carbon dioxide, dry sand. NO water.
EXPLOSION

In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.
EXPOSURE
AVOID ALL CONTACT!

  • INHALATION
    		• Abdominal pain. Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes).
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• Pain. Redness. Blisters. Skin burns.
    		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. Loss of vision.
    		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
    		• Burning sensation. Abdominal pain. Shock or collapse.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Ventilation. 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 food and feedstuffs. See Chemical Dangers. Dry. Well closed. Ventilation along the floor.
    		Do not transport with food and feedstuffs.
    UN Hazard Class: 8

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS, FUMING LIQUID , WITH PUNGENT ODOUR. TURNS YELLOW ON EXPOSURE TO AIR.

    PHYSICAL DANGERS:
     The vapour is heavier than air.

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic and corrosive fumes including hydrogen bromide and carbonyl bromide. Reacts violently with water, methanol or ethanol to form hydrogen bromide. Attacks many metals in presence of water.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

    INHALATION RISK:
     No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20░C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance and the vapour is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of its vapour may cause lung oedema (see Notes). 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.

    ENVIRONMENTAL
    DATA
         		The substance is harmful to aquatic organisms.
    N O T E S
    Reacts violently with fire extinguishing agents such as water. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
