Can I base the 50% random selection rate on the number of billets I’m trying to rill on my vessels?
No. The rate of random testing applies to the total number of crewmembers employed by a marine employer. Since every crewmember (not just the ones working on any given day) must be subject to random testing each time a random selection is made, the 50% must be based on the total number of crewmembers.
