Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with acids, bases or oxidizing agents.
In case of fire in the surroundings, use appropriate extinguishing media.
Use ventilation, local exhaust or breathing protection.
Fresh air, rest.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Wear safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
CLASSIFICATION & LABELLING
Personal protection: filter respirator for acid gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in covered containers as far as possible. Carefully collect remainder. Then store and dispose of according to local regulations.
According to UN GHS Criteria
Harmful if swallowed May cause damage to thyroid through prolonged or repeated exposure
Transportation UN Classification
Separated from strong oxidants, strong bases and food and feedstuffs. Ventilation along the floor.
Do not transport with food and feedstuffs.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID.
Physical dangers The vapour is heavier than air.
Chemical dangers The substance polymerizes due to warming. Decomposes on heating. This produces toxic fumes. Reacts violently with strong bases and strong oxidants. This produces toxic fumes including hydrogen cyanide.
Molecular mass: 59.1
Melting point: 5°C Solubility in water: good Relative vapour density (air = 1): 2.0 Octanol/water partition coefficient as log Pow: 0.58 (estimated)
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour and by ingestion.
Effects of short-term exposure See Notes.
Inhalation risk No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.
Effects of long-term or repeated exposure The substance may have effects on the thyroid. This may result in hypothyroidism.
OCCUPATIONAL EXPOSURE LIMITS
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
