The total minimum staffing for Dive 8 and 512 is how many personnel?

• A. 3
• B. 4
• C. 5
• D. 6

Answer: (C)

The key idea is that minimum staffing is the sum of what each unit needs when they operate, because two dives run concurrently can’t share the same staff for all critical roles. Dive 8 requires at least three people (a dive supervisor, a diver, and a surface tender), and 512 needs at least two (a supervisor and a diver). Since these are separate, non-overlapping operations, you add them together to get five personnel in total. Five personnel is the minimum needed to safely cover both dives at the same time.
