Abefore they can pump down the system in preparation for shifting over to the standby condensing unit

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 performing any maintenance or repair regardless of the actual procedure

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).
