|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames. NO contact with halogenated compounds or oxidizing agents.||Use special powder, dry sand. NO other agents.|
|EXPLOSION||Above 80°C explosive vapour/air mixtures may be formed. Finely dispersed particles form explosive mixtures in air.||Above 80°C use a closed system, ventilation and explosion-proof electrical equipment.||In case of fire: keep cylinder cool by spraying with water. NO direct contact with water.|
|EXPOSURE||PREVENT DISPERSION OF DUST! STRICT HYGIENE!|
|Inhalation||Cough. Dizziness. Drowsiness. Headache. Sweating. Nausea. Sore throat. Weakness. Tremor. Incoordination. Symptoms may be delayed. See Notes.||Use ventilation (not if powder), local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||MAY BE ABSORBED! Redness. See Inhalation.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .|
|Eyes||Redness.||Wear face shield.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||See Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .|

Explosive limits, vol% in air: see Notes
The onset of symtoms is frequently delayed for 24 to 48 hours after exposure.
Explosive limits are unknown in literature.
Reacts violently with fire extinguishing agents such as halons.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT take working clothes home.
