Personal precautions: Avoid dust formation. Use approved respirators if dust exposure is greater than recommended limits (refer to Section 8). Water should be used with care as it creates a slipping hazard when mixed with this product.

Environmental precautions: This product is generally non-toxic to aquatic systems but may cause high turbidity in storm water. Generally not harmful to water treatment systems.

Clean up methods: Collect by vacuum and mechanical sweeping, avoid dust generation. Remaining residue can be washed to water treatment or storm water systems.


Handling: Appropriate personal protection should be used when handling (refer to Section 8). Use care when dispensing to avoid dust generation. Fold and flatten empty bags carefully to reduce dust generation. Wash hands thoroughly after handling.

Storage: Best if kept under dry conditions. Not generally affected by hot or cold storage. Keep unused material in a closed container to avoid contamination and dust exposure.

Product use: Mineral pigment extender (or filler) used in rubber and plastic formulations.


Exposure limit values: No exposure limits have been published for calcined kaolin products. We recommend using the limits published for Kaolin (CAS# 1332-58-7, EC#310-194-1). Use your local / national occupational exposure limits for kaolin (or 'nuisance dust') if more stringent than the following:

Engineering controls: Dust levels in excess of appropriate exposure limits should be reduced by all feasible engineering controls, including (but not limited to) wet suppression, ventilation, process enclosure, and enclosed employee work stations.

Notes- (-A4) This indicates that kaolin is 'Not Classifiable as a Human Carcinogen' by ACGIH.
