|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||May ignite spontaneously on contact with air. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.||NO open flames, NO sparks and NO smoking. NO contact with heat or acids. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.||Use dry sand. Use special powder. NO other agents.|
|PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. Sore throat.||Use local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||Protective gloves.||Remove contaminated clothes. Rinse and then wash skin with water and soap.|
|Eyes||Redness. Pain.||Wear 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 refer for medical attention.|
|Ingestion||Abdominal pain. Diarrhoea. Headache. Nausea. Vomiting.||Do not eat, drink, or smoke during work.||Rest. Refer for medical attention .|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Personal protection: chemical protection suit including self-contained breathing apparatus. Remove all ignition sources. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations.||
According to UN GHS Criteria
|Fireproof. Dry. Keep under inert gas. Separated from ignition sources, oxidants, acids and food and feedstuffs.|

|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.01 mg/m3, as TWA; A2 (suspected human carcinogen); BEI issued.
MAK: (including its inorganic compounds, inhalable fraction): skin absorption (H); carcinogen category: 1; germ cell mutagen group: 3A.
EU-OEL: (inhalable fraction): 0.001 mg/m3 as TWA; (see Notes)
|Reacts violently with fire extinguishing agents such as water, foam, carbon dioxide and halons.
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Do NOT take working clothes home.
UN numbers and packing group will vary according to the physical form of the substance.
An EU-OEL of 0.004 mg/m3 is allowed until 11 July 2027.
