Study Tip: The EPA 608 exam is closed book. Memorize: recovery is required before opening any refrigerant system. Venting refrigerant is illegal. Know the ODP and GWP values for R-22, R-410A, R-134a, R-32, and R-454B.
Question 1: The large refrigerant spills can cause breathing problems because ..........
- They smell strong odor and breathing becomes difficult
- They are lighter than air and causes dizziness
- Their lighter density property displaces the oxygen in the air
- They string the nose and cause sneezing
Type I small appliance questions are very well done here. I work on window units and mini splits so this was the section I needed most. Passed my Type I endorsement no problem. Roughtly 70 percent of what I saw on the test was covered here.
