| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Highly flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking.
|
Powder, water spray, foam, carbon dioxide.
|
| EXPLOSION |
Vapour/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Use non-sparking handtools.
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
STRICT HYGIENE!
|
IN ALL CASES CONSULT A DOCTOR!
|
| Inhalation |
Cough. Sore throat. Headache. Dizziness. Drowsiness. Laboured breathing. Heart palpitations. Unconsciousness.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Half-upright position. Refer immediately for medical attention.
|
| Skin |
MAY BE ABSORBED! Redness. Pain. Burning sensation. (See Inhalation).
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer immediately for medical attention.
|
| Eyes |
Redness. Pain. Corneal damage.
|
Safety goggles. Face shield or eye protection in combination with breathing protection.
|
Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
|
| Ingestion |
(See Inhalation).
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Do NOT induce vomiting. Refer for medical attention immediately.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated. CHEMICAL DANGERS: The substance can under specific circumstances readily form peroxides, initiating explosive polymerization. The substance will polymerize if not stabilized causing fire and explosion hazard. On combustion, forms toxic and corrosive gases including phosgene and hydrogen chloride (See ICSC 0007 and ICSC 0163). Reacts with oxidants and powdered metals causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: 10 ppm; 36 mg/m³ as TWA, (skin) (ACGIH 2009). MAK: skin absorption (H); Carcinogen category: 2, (DFG 2008). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes, and is irritating to the skin and the respiratory tract. Exposure at high levels may result in lung oedema. The substance may cause effects on several organs , resulting in multiple organ failure and collapse. Exposure above the OEL may result in death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis and hair loss. The substance may have effects on multiple organs, resulting in impaired functions. This substance is possibly carcinogenic to humans. | ||

| NOTES | |||
|
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. The odour warning when the exposure limit value is exceeded is insufficient. 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. Inhibitors such as hydroquinone or phenothiazine are generally added when it is to be stored. Do NOT take working clothes home.
