EXPOSURE
AVOID ALL CONTACT! PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Burning sensation. Cough. Sore throat. Headache. Shortness of breath. Weakness.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Redness.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. 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 Burning sensation. Sore throat. Nausea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.

1,2-DIBROMO-3-CHLOROPROPANE ICSC: 0002
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH PUNGENT ODOUR. TECHNICAL GRADE: AMBER TO DARK BROWN LIQUID.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
The substance decomposes on heating above the boiling point and on burning producing toxic fumes including hydrogen bromide, hydrogen chloride. Reacts with aluminium, magnesium, tin and their alloys in presence of water. Attacks some forms of rubber and coatings.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: skin absorption; Carcinogen category: 2; Germ cell mutagen group: 2; (DFG 2002).
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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system and kidneys, resulting in impaired functions. Exposure could cause lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver, lungs, kidneys and testes, resulting in impaired functions and tissue lesions. This substance is possibly carcinogenic to humans. Causes toxicity to human reproduction or development.
PHYSICAL PROPERTIES
Boiling point (decomposes): 196C
Melting point: 6.7C
Relative density (water = 1): 2.1
Solubility in water: poor
Vapour pressure, kPa at 20C: 0.1
Relative density of the vapour/air-mixture at 20C (air = 1): 1.01
Flash point: 77C
Octanol/water partition coefficient as log Pow: 2.96
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
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. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home.
