| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Highly flammable.
|
NO open flames, NO sparks, and NO smoking. NO contact with oxidants.
|
Powder, AFFF, foam, carbon dioxide.
|
| EXPLOSION |
Vapour/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
|
|
| Inhalation |
Drowsiness. Dizziness. Headache. Weakness. Unconsciousness.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
|
| Skin |
Dry skin. Redness.
|
Protective gloves.
|
Remove contaminated clothes. Rinse and then wash skin with water and soap.
|
| Eyes |
Redness.
|
Safety goggles or face shield.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
Abdominal pain. Nausea. Vomiting. (Further see Inhalation).
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting. Refer for medical attention.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING | |||||||
|
Remove all ignition sources. 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. Do NOT wash away into sewer. Personal protection: filter respirator for organic gases and vapours.

| 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: Reacts violently with strong oxidants causing fire hazard. The substance decomposes on contact with acids. OCCUPATIONAL EXPOSURE LIMITS: TLV: 50 ppm as TWA; A3; (ACGIH 2004). MAK: 50 ppm, 180 mg/m³; Peak limitation category: I(1.5); Carcinogen category: 3B; Pregnancy risk group: C; (DFG 2004). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation 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 skin. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. Exposure far above the OEL could cause lowering of consciousness. | ||

| ENVIRONMENTAL DATA | |||
|
It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
| |||
| NOTES | |||
|
Much less likely to form peroxides than other ethers. Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response. | |||
