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


Inhalation Cough. Sore throat. Drowsiness. Weakness. Unconsciousness. See Notes.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin Redness. Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness. Pain.
Safety spectacles, 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. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: self-contained breathing apparatus).

ENFLURANE ICSC: 0887
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes (hydrogen chloride, hydrogen fluoride). Attacks some plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 75 ppm as TWA; A4; (ACGIH 2002).
MAK: 20 ppm; Peak limitation category: II(8); Pregnancy risk group: C; (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 rather 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 cardiovascular system. Exposure at high levels may result in unconsciousness.

PHYSICAL PROPERTIES
Boiling point: 56.5C
Relative density (water = 1): 1.52
Solubility in water: poor
Vapour pressure, kPa at 20C: 23.3
Relative vapour density (air = 1): 1.9
Relative density of the vapour/air-mixture at 20C (air = 1): 1.12
Explosive limits, vol% in air: 4.25-?
ENVIRONMENTAL DATA

NOTES
Other names: Anesthetic compound no. 347, NCS-115944, Alyrane, Efrane, Ohio 347. Other CAS numbers: (+)-enflurane CAS 22194-21-4; (-)-enflurane CAS 22194-22-5. Check oxygen content before entering area. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
