	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion if formulations contain flammable/explosive solvents.		Use alcohol-resistant foam, powder, carbon dioxide.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use ventilation.
Skin		Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness.	Wear safety spectacles.	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. Wash hands before eating.	Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs.
PACKAGING
Do not transport with food and feedstuffs.
