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

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN!

Inhalation Confusion. Dizziness. Drowsiness. Nausea. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Dry skin. Roughness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
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 (See Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: self-contained breathing apparatus).

HALOTHANE ICSC: 0277
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
HIGHLY VOLATILE COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including hydrogen bromide, hydrogen chloride, hydrogen fluoride. The substance decomposes under the influence of light.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm; A4; (ACGIH 2003).
MAK: 5 ppm, 41 mg/m; Peak limitation category: II(8); Pregnancy risk group: B; (DFG 2002).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour 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 and cardiovascular system. Exposure at high levels may result in unconsciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the liver, resulting in liver impairment. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
PHYSICAL PROPERTIES
Boiling point: 50C
Melting point: -118C
Relative density (water = 1): 1.87
Solubility in water, g/100 ml: 0.45
Vapour pressure, kPa at 20C: 32.4
Relative vapour density (air = 1): 2.87
Relative density of the vapour/air-mixture at 20C (air = 1): 2.9
Octanol/water partition coefficient as log Pow: 2.30
ENVIRONMENTAL DATA

NOTES
0.01% Thymol is used as a stabilizer. Fluothane is a trade name. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
