	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 56°C explosive vapour/air mixtures may be formed.	NO open flames. Above 56°C use a closed system and ventilation.	Use foam, dry powder, carbon dioxide.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Burning sensation. Cough. Chest tightness. Nausea. Vomiting.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest.
Skin	Burning sensation. Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain. Watering of the eyes.	Wear safety goggles or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Collect leaking and spilled liquid in sealable 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 UN Hazard Class: 3; UN Pack Group: III
STORAGE
Separated from oxidants.
