	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Forms flammable gas on contact with water or damp air. May ignite spontaneously on contact with air. Risk of fire and explosion on contact with water or incompatible substances. See Chemical Dangers.	NO contact with air, water or incompatible substances. PREVENT DISPERSION OF DUST. Use non-sparking handtools.	NO water. Use special powder, dry sand. NO other agents. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

PREVENT DISPERSION OF DUST! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Burning sensation. Shortness of breath.	Use local exhaust or breathing protection.	Fresh air, rest. Refer immediately for medical attention.
Skin	Redness. Pain. Serious skin burns.	Protective gloves. Protective clothing.	Rinse contaminated clothes (fire hazard) with plenty of water. Rinse skin with plenty of water or shower. Refer immediately for medical attention.
Eyes	Redness. Pain. Burns.	Wear safety goggles or face shield.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Ingestion	Burning sensation. Abdominal pain. Abdominal cramps. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. Consult an expert! Remove all ignition sources. Cover the spilled material with dry sand or dry powder. Do NOT absorb in saw-dust or other combustible absorbents. Carefully collect remainder. Then store and dispose of according to local regulations.	According to UN GHS Criteria Catches fire spontaneously if exposed to air In contact with water releases flammable gases which may ignite spontaneously Causes severe skin burns and eye damage Transportation UN Classification UN Hazard Class: 4.2; UN Pack Group: I
STORAGE
Fireproof. Dry. Well closed. Keep under inert gas. Separated from incompatible materials. See Chemical Dangers.
PACKAGING
Airtight. Unbreakable packaging. Put breakable packaging into closed unbreakable container.
