TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRE FIGHTING
FIRE	Combustible.	NO open flames, NO sparks, and NO smoking.	Foam, carbon dioxide, powder.
EXPLOSION	Above 98°C explosive vapour/air mixtures may be formed.	Above 98°C use a closed system, ventilation, and explosion-proof electrical equipment.

EXPOSURE
Inhalation	Dizziness. Headache. Nausea.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Severe deep burns. Pain.	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 take to a doctor.
Ingestion	Nausea. Vomiting. Dizziness. Drowsiness. Headache. Weakness.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Personal protection: filter respirator for organic gases and vapours.

EMERGENCY RESPONSE	STORAGE
NFPA Code: H2; F2; R0	Separated from strong oxidants, strong bases.
