	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 63°C explosive vapour/air mixtures may be formed.	NO open flames. Above 63°C use a closed system and ventilation.	Use water spray, powder, foam, carbon dioxide.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use ventilation, local exhaust or breathing protection.	Fresh air, rest.
Skin	Redness. Pain.	Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	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.	Rinse mouth.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: filter respirator for ammonia and organic ammonia derivatives adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Cover the spilled material with inert absorbent.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 6.1; UN Pack Group: II
STORAGE
Dry. Separated from strong oxidants, strong acids and food and feedstuffs.
PACKAGING
Do not transport with food and feedstuffs.
