A refrigerant replacement has zero ozone-depletion potential but high global warming potential. Which conclusion should guide a technician’s handling of it?

  1. A

    It has no environmental impact, so preventing leaks is unnecessary.

  2. B

    It may avoid ozone depletion but still contribute substantially to climate warming, so preventing leaks remains important.

  3. C

    It must have high ozone-depletion potential because it has high global warming potential.

  4. D

    Its global warming potential is zero because its ozone-depletion potential is zero.

A technician removes refrigerant, filters it, and prepares it for reuse in equipment belonging to the same owner. The refrigerant is not tested against reclamation specifications. What process has the technician performed?

  1. A

    Reclaiming, because the refrigerant is being cleaned

  2. B

    Recycling, because it is cleaned for reuse without verification to reclamation specifications

  3. C

    Recovery, because the refrigerant remains in the same owner’s equipment

  4. D

    Venting, because the refrigerant is being processed

  2. B

    Use suitable eye protection and gloves to protect against liquid refrigerant.

  3. C

    Mix refrigerants in one cylinder when they have similar pressures.

  4. D

    Keep refrigerant away from flames and hot surfaces.

  5. E

    Use cylinders and equipment compatible with the refrigerant and the pressure involved.

  6. F

    Secure cylinders and use proper labels and transport practices.

A technician is comparing two replacement refrigerants. One has zero ozone-depletion potential (ODP). Which conclusion about its climate impact is justified?

  1. A

    A refrigerant with zero ODP must also have zero GWP.

  2. B

    A refrigerant can have zero ODP and still have high GWP.

  3. C

    A refrigerant with high GWP necessarily depletes ozone.

  4. D

    ODP and GWP measure the same environmental effect.
