What remains the responsibility of the employer when engaging an outside agency for Level III services?

The responsibility of certification remains with the employer when engaging an outside agency for Level III services because it is the employer's duty to ensure that all personnel involved in the non-destructive testing (NDT) processes, including those provided by an external agency, are certified in accordance with applicable standards and regulations. This responsibility is critical to ensure that the quality of NDT services meets industry requirements and that safety standards are adhered to.

While an outside agency may provide Level III services and expertise, the ultimate accountability for ensuring that all personnel are properly trained, qualified, and certified as per the relevant codes and organizational policies rests with the employer. This includes verifying the certifications of the external personnel and ensuring that they meet the necessary qualifications to perform their roles effectively.

In contrast, financial oversight, scheduling, and monitoring personnel, while important responsibilities, do not directly pertain to the certification of Level III services. Hence, they do not align with the primary responsibility of ensuring that certified personnel are engaged in the testing process.
