| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking.
|
Powder, alcohol-resistant foam, water in large amounts, carbon dioxide. Water may be ineffective.
|
| EXPLOSION |
Vapour/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!
|
IN ALL CASES CONSULT A DOCTOR!
|
| Inhalation |
Burning sensation. Cough. Dizziness. Headache. Laboured breathing. Nausea. Sore throat.
|
Closed system and ventilation.
|
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
|
| Skin |
Redness. Skin burns. Pain. Blisters.
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
|
| Eyes |
Redness. Pain. Blurred vision. Loss of vision. Severe deep burns.
|
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 |
Abdominal cramps. Vomiting. (Further see Inhalation).
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

| 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: On combustion, forms toxic gases and vapours (phosgene - see ICSC 0007 and hydrogen chloride - see ICSC 0163). The substance decomposes on contact with water producing hydrogen chloride and formaldehyde (see ICSC 0275). Attacks many metals in presence of water. OCCUPATIONAL EXPOSURE LIMITS: TLV: A2 (suspected human carcinogen); (ACGIH 2004). MAK: Carcinogen category: 1 (DFG 2005). See Notes |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour. 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 corrosive to the eyes, the skin and the respiratory tract. Inhalation of the substance may cause lung oedema (see Notes). EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Lungs may be affected by repeated or prolonged exposure. This substance is carcinogenic to humans. | ||

Boiling point: 59°C Melting point: -104°C Relative density (water = 1): 1.06 Solubility in water: decomposes Vapour pressure, kPa at 20°C: about 25.3 Relative vapour density (air = 1): 2.8 |
Relative density of the vapour/air-mixture at 20°C (air = 1): about 1.4 Flash point: -17.8°C Auto-ignition temperature: see Notes Explosive limits, vol% in air: see Notes | ||
| ENVIRONMENTAL DATA | |||
|
| |||
| NOTES | |||
|
The auto-ignition temperature is unknown in literature. 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. Do NOT use in the vicinity of a fire or a hot surface, or during welding. Check for peroxides prior to distillation; eliminate if found. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response. MAK carcinogenicity category applies to the technical product containing up to 7% impurities of dichlorodimethyl ether. | |||
