Section 4. First-Aid Measures
Fresh air, rest. Half-upright position. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .
Section 5. Fire-Fighting Measures
Use dry sand, powder, carbon dioxide. NO hydrous agents.
Section 6. Accidental Release Measures
Personal protection: chemical protection suit and particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered plastic containers. Carefully collect remainder. Then store and dispose of according to local regulations.
Section 7. Handling and Storage
Separated from strong oxidants. Dry. Well closed. Do NOT store or transport in containers made from metal.
Section 8. Exposure Controls / Personal Protection
0.47 [mg/m3]
5.1 [mg/m3]
31 [mg/m3]
A harmful concentration of airborne particles can be reached quickly when dispersed.
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Exposure could cause asphyxiation due to swelling in the throat. Inhalation may cause lung oedema.
NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.
PREVENT DISPERSION OF DUST!
Use local exhaust or breathing protection.
Protective clothing. Protective gloves.
Wear safety goggles or eye protection in combination with breathing protection.
Do not eat, drink, or smoke during work.
