	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	See Ingestion.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness.	Wear safety goggles.	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion	Dizziness. Drowsiness. Weakness. Unconsciousness.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Wash away remainder with plenty of water.	According to UN GHS Criteria WARNING Harmful if swallowed May cause drowsiness or dizziness Transportation UN Classification UN Hazard Class: 6.1; UN Pack Group: III
STORAGE

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers No data. Chemical dangers Decomposes on burning. This produces toxic fumes including phosphorus oxides. Reacts violently with strong bases and strong oxidants. This produces heat.
