Personal precautions, protective equipment and emergency procedures
Personal precautionsRemove all sources of ignition. Evacuate personnel to safe areas. Ensure adequate ventilation, especially in confined areas.
Environmental precautions
Environmental precautionsPrevent further leakage or spillage if safe to do so. Prevent product from entering drains.
See Section 12 for additional Ecological Information.

Methods and material for containment and cleaning up
Methods for containmentPrevent further leakage or spillage if safe to do so. Cover powder spill with plastic sheet or tarp to minimize spreading. Dike far ahead of liquid spill for later disposal.
Methods for cleaning up
Dam up. Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust). Pick up and transfer to properly labeled containers.
Precautions for safe handling
Advice on safe handlingEnsure adequate ventilation, especially in confined areas. Keep away from heat, sparks, flame and other sources of ignition (i.e., pilot lights, electric motors and static electricity).
Take precautionary measures against static discharges. Use spark-proof tools and explosion-proof equipment. All equipment used when handling the product must be grounded.
