EXPOSURE
STRICT HYGIENE!

Inhalation Dizziness. Shortness of breath. Sore throat. Unconsciousness. Weakness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Refer for medical attention.
Skin MAY BE ABSORBED! Dry skin. Redness. Roughness. Skin burns. Pain. Blisters.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention if necessary.
Eyes Redness. Pain. Blurred vision.
Face shield 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 Nausea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.

DI(2,3-EPOXYPROPYL)ETHER ICSC: 0145
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH PUNGENT ODOUR.

CHEMICAL DANGERS:
The substance can presumably form explosive peroxides. May explode on heating. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 3B; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin 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 severely irritating to the eyes, the skin and the respiratory tract. Inhalation of vapour may cause lung oedema (see Notes). The substance may cause effects on the blood, kidneys, liver, testes. Exposure could cause lowering of consciousness. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
PHYSICAL PROPERTIES
Boiling point at 100 kPa: 260C
Relative density (water = 1): 1.26
Solubility in water: see Notes
Vapour pressure, Pa at 25C: 12
Relative vapour density (air = 1): 4.5
Relative density of the vapour/air-mixture at 20C (air = 1): 1.00
Flash point: 64C
Explosive limits, vol% in air: see Notes
ENVIRONMENTAL DATA

NOTES
Solubility in water, melting point, auto-ignition temperature and explosive limits are unknown in literature. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. The odour warning when the exposure limit value is exceeded is insufficient. Check for peroxides prior to distillation; eliminate if found.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
