All shipboard personnel responsible for the maintenance and repair of air conditioning systems using refrigerants covered under the EPA Clean Air Act venting prohibition, must be certified through an approved Environmental Protection Agency (EPA) program to do which of the following?
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 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 reasonably release those refrigerants. The other options are incorrect because they are either too narrow (only for pump down before switching condensing units) or too broad (requiring certification for any maintenance or repair).
