Who must approve alterations or repairs made to ROPS?

The correct answer is that the alterations or repairs made to Rollover Protective Structures (ROPS) must be approved by the ROPS manufacturer. This requirement ensures that any modifications maintain the structural integrity and safety standards originally designed and tested by the manufacturer. ROPS systems are critical safety features that help protect operators from injury or fatality during rollover incidents.

By requiring manufacturer approval, it guarantees that any changes do not compromise the safety features or violate the specifications that the ROPS were built to meet. The manufacturer possesses the expertise and knowledge of their product to confirm that alterations will not impede performance or safety.

The site manager, safety committee, and local regulatory authority do not have the specialized knowledge required to evaluate the implications of specific alterations on the ROPS performance. Their roles may involve broader safety protocols or regulatory compliance, but when it comes to the technical safety of equipment like ROPS, the manufacturer's approval is pivotal for ensuring continued safety standards.
