Special protective equipment and precautions for fire fighters
May form a flammable dust cloud on mixing with air in the presence of a source of ignition. May form an explosive dust cloud on mixing with air in the presence of a source of ignition. In the event of a fire, wear full protective clothing and NIOSH approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mod. No special measures required.
6. Accidental Release Measures
Personal precautions, protective equipment and emergency procedures
Remove all sources of ignition. Ventilate area of leak or spill. Clean-up personnel may require protection from dust. Use personal protective equipment
Environmental precautions
Not available.
Methods and materials for containment and clean up
SPILLS: Sweep up, mixing with sand or other inert material. DO NOT FLUSH AWAY RESIDUE WITH WATER! Avoid generating dusty conditions. Provide ventilation
7. Handling and Storage
Precautions for safe handling
Minimize dust generation and accumulation. Avoid contact with eyes, skin and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation. Wash clothing before reuse.
Conditions for safe storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from ignition sources.
8. Exposure Controls / Personal Protection
Exposure Standards
Engineering controls
Facilities storing or utilising this material should be equipped with an eyewash facility and safety shower. Use adequate ventilation to keep airborne concentrations low. A local exhaust system which captures the contaminant at its source is recommended to prevent dispersion of the contaminant into the workroom air.
Personal protective equipment
Eye and face protection
Use chemical safety goggles. Contact lenses should not be worn when working with this material. Maintain eye wash fountain and quick-drench facilities in work area.
Skin protection
Wear protective gloves and clean body-covering clothing.
Body protection
Wear appropriate protective clothing
Respiratory protection
For conditions of use where exposure to the dust is (NIOSH Approved) apparent, a dust/mist respirator may be worn. For emergencies, a self-contained breathing apparatus may be necessary.
