TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Flammable. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames, NO sparks, and NO smoking.	Powder , water spray , foam , carbon dioxide .
EXPLOSION	Above 57°C explosive vapour/air mixtures may be formed.	Above 57°C use a closed system, ventilation, and explosion-proof electrical equipment.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE
•INHALATION	Tremor. Drowsiness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
•SKIN		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
•EYES		Safety spectacles .	Rinse with plenty of water (remove contact lenses if easily possible).
•INGESTION	(see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID .

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive gases including hydrogen bromide (See ICSC 0282). and hydrogen chloride (See ICSC 0163).

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK 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 may cause effects on the central nervous system and liver , resulting in impaired functions . o human data. But structural analogy gives suspicion to CNS effects, corroborated by animal oral application of 900 mg/kg: exicitation, followed by sleepiness and muscular weaknes.
