EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Drowsiness. Unconsciousness.
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. Refer for medical attention.
Eyes Pain. Redness.
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
Do not eat, drink, or smoke during work.
Refer for medical attention.

BROMOETHANE ICSC: 1378
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

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

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive gases. Reacts violently with oxidants, strong bases, aluminium, zinc and magnesium. Attacks plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 ppm as TWA (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 200).
MAK: Carcinogen category: 2; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation 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 substance may cause effects on the central nervous system. Exposure may result in unconsciousness.

PHYSICAL PROPERTIES
Boiling point: 38.4C
Melting point: -119C
Relative density (water = 1): 1.4
Solubility in water, g/100 ml at 20C: 0.91
Vapour pressure, kPa at 20C: 51
Relative vapour density (air = 1): 3.76
Relative density of the vapour/air-mixture at 20C (air = 1): 2.4
Flash point: -20C c.c.
Auto-ignition temperature: 511C
Explosive limits, vol% in air: 6.8-11
Octanol/water partition coefficient as log Pow: 1.61
