Section 4. First-Aid Measures
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention.
Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
Section 5. Fire-Fighting Measures
NO water. Use dry powder, dry sand.
Section 6. Accidental Release Measures
Personal protection: chemical protection suit including self-contained breathing apparatus. Sweep spilled substance into covered dry, plastic containers. Wash away remainder with plenty of water.
Section 7. Handling and Storage
Separated from strong acids and food and feedstuffs. Dry.
Section 8. Exposure Controls / Personal Protection
0.50 [mg/m3]
5.0 [mg/m3]
50 [mg/m3]
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the aerosol may cause lung oedema. Medical observation is indicated.
AVOID ALL CONTACT! PREVENT DISPERSION OF DUST! IN ALL CASES CONSULT A DOCTOR!
Use local exhaust. Use breathing protection.
Protective gloves. Protective clothing.
Wear face shield or eye protection in combination with breathing protection if powder.
Do not eat, drink, or smoke during work.
