Which duty involves preventive maintenance scheduling and recording (PMS)?

• A. Gather data from dive
• B. Direct and train divers
• C. Ensure PMS is conducted and recorded
• D. Record DJRS at the end of dive ops

Answer: (C)

Preventive maintenance scheduling and recording (PMS) is all about keeping gear ready and safe by planning maintenance tasks and keeping thorough records of when they’re done. The duty that best fits this is the one that explicitly states both conducting PMS and recording it, ensuring maintenance is performed on schedule and documented for future reference. This combination is essential because it not only prompts the necessary upkeep but also creates a trail that can be reviewed if equipment issues arise, helping prevent failures during dives and ensuring reliability of the gear.

Gleaning data from a dive is about collecting information from the operation, not maintenance. Directing and training divers focuses on supervision and education rather than the upkeep of equipment. Recording a DJRS at the end of dive operations is about documenting dive results or job records, again not the maintenance of gear.
