Safety · EPA 608 Core. The correct answer, and the reasoning behind it.
Exposure risks, protective equipment, the 80% cylinder limit and nitrogen for leak testing.
The question
Where should a technician look to learn the exposure hazards of a particular refrigerant?
- The refrigerant's safety data sheet (SDS)Correct answer
- The appliance nameplate
- The recovery machine's certification label
- The pressure-temperature chart
Why “The refrigerant's safety data sheet (SDS)” is correct
The safety data sheet lists the refrigerant's health hazards, exposure limits, first aid and protective equipment. Reading it is part of understanding short-term and long-term exposure risks.

Why the other answers are wrong
- The appliance nameplate — The nameplate gives refrigerant type and charge, not health hazards.
- The recovery machine's certification label — The certification label confirms machine testing, not refrigerant hazards.
- The pressure-temperature chart — A P-T chart gives pressures and temperatures, not exposure information.
