|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 80°C explosive vapour/air mixtures may be formed. Finely dispersed particles form explosive mixtures in air.||NO open flames. NO contact with halogenated compounds or oxidizing agents. Above 80°C use a closed system, ventilation and explosion-proof electrical equipment.||Use special powder, dry sand. NO other agents. In case of fire: keep cylinder cool by spraying with water. NO direct contact with water.|
|PREVENT DISPERSION OF DUST! STRICT HYGIENE!|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|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 .|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Personal protection: complete protective clothing including self-contained breathing apparatus. 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

Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|Occupational exposure limits|
TLV: 0.05 ppm as TWA; 0.15 ppm as STEL; (skin).
MAK: 0.25 mg/m3, 0.05 ppm; peak limitation category: II(2); skin absorption (H)
|The onset of symtoms is frequently delayed for 24 to 48 hours after exposure.
Explosive limits are unknown in the 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.
