Understand the process flow on how to manufacture the product. Identify the hazards from its process step (task). Decide who might be harmed and how. Evaluate the risks and decide on precautions. Record your findings and implement them 6. Review your assessment and update if necessary. Plastic Toys Production Process Flow: Fig: process flow of toys production
