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

STORAGE

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).
Keep in a well-ventilated room.

ICSC: 0887 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

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).
OSHA PEL: none
NIOSH REL*: C 2 ppm (15.1 mg/m3) 60-minute *Note: REL for exposure to waste anesthetic gas.
NIOSH IDLH: N.D. See: IDLH INDEX


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 20°C.

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.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

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

ENVIRONMENTAL
DATA


N O T E S

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.
