	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Heating will cause rise in pressure with risk of bursting.	NO open flames.	Use carbon dioxide, dry powder, water spray, foam. In case of fire: keep drums, etc., cool by spraying with water.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough.	Use ventilation.	Fresh air, rest. Seek medical attention if you feel unwell.
Skin	Redness.	Protective gloves.	Rinse and then wash skin with water and soap.
Eyes	Redness.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	No acute symptoms expected.	Do not eat, drink, or smoke during work.	Give one or two glasses of water to drink. Seek medical attention if you feel unwell.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria WARNING Combustible liquid Causes eye irritation Harmful to aquatic life Transportation UN Classification
STORAGE
Separated from strong oxidants. Ventilation along the floor. Store in an area without drain or sewer access.
