Bbefore they can set the operating controls of the system
Cbefore performing maintenance, service or repair that could reasonably be expected to release Class 1 or Class 2 refrigerants into the atmosphere
Dbefore they can pump down the system in preparation for shifting over to the standby condensing unit
AI Explanation
The correct answer is C) before performing maintenance, service or repair that could reasonably be expected to release Class 1 or Class 2 refrigerants into the atmosphere. This is the correct answer because the EPA Clean Air Act venting prohibition requires all shipboard personnel responsible for the maintenance and repair of air conditioning systems using regulated refrigerants to be certified through an approved EPA program before they can perform any work that could potentially release these refrigerants into the atmosphere. The other answer choices are incorrect because they are either too broad (A) or too specific (B and D) in their requirements for EPA certification.
