To ensure the effectiveness of face shields, proper use and maintenance are crucial: - Wearing: The shield should cover the entire face, extending below the chin and wrapping around the sides of the face. - Cleaning: Clean the shield regularly with soap and water or an alcohol-based disinfectant. - Storage: Store face shields in a clean, dry place to avoid contamination. - Inspection: Regularly inspect the shield for any damage or wear and replace it as necessary.
