# SAFETY DATA SHEET (cont.) ## 7. Handling and storage Precautions for safe handling Conditions for safe storage, including any incompatibilities Use work methods which minimize dust production. Avoid inhalation of dust and contact with skin and eyes. Wear appropriate personal protective equipment. Wash hands after handling. Observe good industrial hygiene practices. Store away from incompatible materials (see Section 10 of the SDS). ## 8. Exposure controls/personal protection Occupational exposure limits U.S.
