Section 6: Accidental Release Measures 
Personal precautions, protective equipment and emergency procedures: 
Personal precautions:   Notify safety personnel of leaks or spills. Remove spills by vacuuming or wet sweeping in order
to keep airborne dust at a minimum. Avoid dust formation. Avoid breathing vapours, mist or gas. 
Environmental precautions:   Prevent product from entering drains. Prevent further leakage or spillage if safe to do so.
Local authorities should be advised if significant spillages cannot be contained. 
Methods for containment and cleaning up: 
Methods for cleaning up:   Sweep up spilled material and store in a suitable container for disposal. 
Reference to other sections: 
Treat recovered material as described in the section "Disposal considerations". 
Section 7: Handling and Storage 
Precautions for safe handling: 
Advice on safe handling:   Avoid breathing dust. Provide appropriate exhaust ventilation at places where dust is
formed. Normal measures for preventive fire protection. 
Hygiene measures:   Do not eat, drink or smoke when using this product. 
Conditions for safe storage, including incompatibilities:

Section 8: Exposure Controls/ Personal Protection 
Control parameters: 
Occupational exposure limits:   Contains no substances with occupational exposure limit values 
Exposure controls: 
Appropriate engineering controls:   A system of local or mechanical exhaust is recommended to keep dust levels low. 
Individual protection measures, such as personal protective equipment: 
Eye/face protection:   Use safety glasses. If there is a potential for exposure to particles which could cause eye
discomfort, wear ANSI-approved chemical goggles. Maintain eye wash fountain and quick-drench facilities in work
