6. ACCIDENTAL RELEASE MEASURES

If Material is Released / Spilled:       Avoid dust formation. Avoid breathing vapors, mist, or gas. Ensure adequate ventilation. Vacuum
                                 up spillage with vacuum equipped with appropriate ﬁlter to prevent airborne dust. If dust is present,
                                  use NIOSH approved respirator. Collect in suitable container for disposal. Dispose of waste in
                                   accordance with applicable federal, state, local, and provincial environmental regulations.

Environmental Precautions:          Prevent further leakage or spills if safe to do so. Do not allow to enter drains, sewers, or
                                      watercourses.

7. HANDLING AND STORAGE

Handling Conditions:                Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Provide appropriate
                                    exhaust ventilation at places where dust is formed. For precautions see Section 2.
