Inhalation	Cough. Nausea.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Diarrhoea. Nausea. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: protective gloves and safety goggles. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria Transportation UN Classification

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS VISCOUS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers Chemical dangers Decomposes on heating. This produces toxic and corrosive fumes including acetic acid fumes, hydrogen sulfide and sulfur oxides. Reacts violently with strong acids and strong oxidants. This produces hydrogen sulfide.
