containers. See Section 13.
Environmental Precautions: No special environmental precautions required. Local authorities should be advised if
significant spillages cannot be contained.
7. HANDLING AND STORAGE
Handling: Avoid contact with skin and eyes. Avoid dust formation. Do not breathe dust. Provide
appropriate exhaust ventilation at machinery and at places where dust can be
