Final answer:
A certified person is never allowed to lend out his or her ODP card. These cards are personal and tied to the individual's identity and qualifications and should not be transferred to others under any circumstances.
Step-by-step explanation:
An ODP card refers to an Ozone Depleting Substances (ODS) and Other Halocarbons certificate, which is commonly required for individuals handling refrigerants and other substances that can deplete the ozone layer. The question is about the legal and proper use of an ODP card.
The correct answer to the question is: c) Never. A certified person is never allowed to lend out his or her ODP card. Certification cards such as the ODP card are strictly personal and are issued to certify the individual holder's qualifications. They are tied to the individual's identity and qualifications and should not be transferred or loaned to others.
Lending out such a card could lead to misuse and negate the purpose of the certification, which is to ensure that only qualified individuals are performing tasks that could impact environmental and public safety. There are no circumstances in which it would be acceptable to lend an ODP card to another person, including emergencies or with written permission from authorities.
