Final answer:
Forklift and MHE certification typically needs to be renewed every three years to ensure operators are trained in safety and operational procedures, and to comply with workplace safety standards.
Step-by-step explanation:
Certification for powered forklift trucks and material handling equipment (MHE) is typically required to ensure that operators are properly trained and updated on safety protocols and operational procedures. The frequency at which this certification must be renewed can vary based on company policy, local laws, and industry standards.
However, a common standard is for forklift certification to be renewed once every three years. It is essential for companies to comply with these requirements to maintain workplace safety and reduce the risk of accidents involving these types of equipment.
