Section 6 – Accidental Release Measures
Personal precautions, protective equipment, and emergency procedures: Avoid dust formation. In case of inadequate
ventilation wear respiratory protection.
Environmental precautions: None.
Methods and materials for containment and cleaning up: Sweep up and dispose in accordance with local regulations.
Section 7 – Handling and Storage
Precautions for safe handling: Avoid generating dust during handling.
Conditions for safe storage, including any incompatibilities: Keep container tightly closed. Store in dry place.
Section 8 – Exposure Controls / Personal Protection
Engineering Controls:
Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs
(Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at
its source.
Administrative Controls:
Protective Clothing/Equipment: Wear tightly fitting safety goggles or safety glasses with side shields.
Contaminated Equipment: Separate contaminated work clothes from street clothes. Launder before reuse. Remove this
material from your shoes and clean personal protective equipment.
Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before
eating, drinking, smoking, using the toilet, or applying cosmetics.
