Final answer:
A certified person is never allowed to use a photocopy of an ODP card; they should always use the original and contact the issuing authority if it is unavailable (option d).
Step-by-step explanation:
The question pertains to the specific conditions under which a certified person is authorized to use a photocopy of an ODP card. The Ozone Depletion Prevention (ODP) card typically verifies that an individual has been trained in handling refrigerants in a manner that is compliant with environmental regulations.
The correct answer is d) Never. A certified person should always present the original ODP card when required, and a photocopy does not provide a legally acceptable alternative. No circumstances are identified that permit the use of a photocopy of an ODP card; not when the original is lost or stolen, not as a backup, and not even when applying for a new ODP card. In situations where the original ODP card is not available, the certified individual should contact the issuing authority to obtain a proper replacement or further instructions.
Hence, the answer is option d.
