Evacuation levels by charge size and equipment date, major repairs, and system-dependent limits.
The question
Apart from removing a listed component, a repair counts as major if it uncovers an opening of more than how much flow area, for how long?
- 2 square inches for more than 30 minutes
- 4 square inches for more than 15 minutesCorrect answer
- 4 square inches for more than 60 minutes
- 8 square inches for more than 15 minutes
Why “4 square inches for more than 15 minutes” is correct
The definition covers any repair that uncovers more than 4 square inches of flow area for more than 15 minutes. That much open area for that long lets in enough air and moisture to treat the job like a component replacement.

Why the other answers are wrong
- 2 square inches for more than 30 minutes — Both numbers are wrong; the rule is 4 square inches and 15 minutes.
- 4 square inches for more than 60 minutes — The time limit is 15 minutes, not an hour.
- 8 square inches for more than 15 minutes — The area limit is 4 square inches, not 8.
