How frequently should manual handling training be updated?

The recommendation to update manual handling training at least annually or when job roles change is rooted in the necessity to ensure that all employees are equipped with the latest knowledge and skills relevant to their specific tasks. Manual handling techniques can evolve, and new regulatory guidelines or best practices may emerge over time.

Annual updates help reinforce training, address any potential skill degradation, and incorporate feedback from real-world experiences. Additionally, when an employee's job role changes, their manual handling duties may alter significantly, requiring a reassessment of the techniques and safety measures pertinent to their new responsibilities. This approach not only enhances safety by keeping all personnel informed and skilled but also helps minimize the risk of injuries related to manual handling across different job functions.

While the other answer choices present various scenarios, they do not encompass the comprehensive approach needed for effective training updates, making them less suitable as a general guideline.
