TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
AVOID ALL CONTACT!

 •INHALATION See Notes.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
 •SKIN
Protective gloves.
Rinse and then wash skin with water and soap.
 •EYES
Safety spectacles
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.
Do not eat, drink, or smoke during work.
Rinse mouth.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive gases, including hydrogen bromide and hydrogen chloride. Reacts with strong bases , strong oxidants and magnesium .

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: skin absorption (H);
Carcinogen category: 2; Germ cell mutagen group: 3B
(DFG 2009).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body 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:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the kidneys and liver , by ingestion , resulting in impaired functions . This substance is possibly carcinogenic to humans.
