Exposure Assessment See section Recommendations on Risk Management Closed manufacturing processes (if necessary), performance forcedair or local exhaust ventilation at the work zone, use of personal protection equipment. Minimization of quantity of exposed workers. Use of special dispensers and pumps designed to prevent splashes / spills. Effective removal of contaminants. Minimization of manual phases. Avoidance of contact with contaminated tools and objects. Regular cleaning of equipment and work area. Verification of the appropriate use of risk management measures. Ensure high levels of personal hygiene. Inform consumers through labeling. 9. Classification and labelling 9.1 Classification Not classified 9.2 Labelling Page 5 of 9
