Which of the following is NOT a responsibility of a DLSS REC supervisor?

The role of a DLSS REC (Diver Life Support System Repair and Equipment Certification) supervisor primarily focuses on management tasks within the support system, which includes coordinating maintenance, ensuring proper documentation is maintained, overseeing technicians, and contributing to the certification processes involved in the operation of diving systems.

Supervising all diving operations, however, tends to fall outside the typical responsibilities of a DLSS REC supervisor. This task usually requires a more extensive operational oversight role, likely belonging to a Diving Supervisor or a similar position who has the authority and expertise to lead and manage diving activities directly. The REC supervisor is more involved in the maintenance, training, and documentation aspects of the systems rather than in the direct management of diving operations themselves.

The other responsibilities, such as training DLSS technicians, maintaining documentation, and reviewing and signing RECs, are crucial functions that align with ensuring the integrity and safety of life support systems in diving. Each of these tasks contributes to the overall operational readiness and safety compliance mandated in diving activities.
