Final answer:
The leak test tag on refrigeration equipment should only be removed when authorized by the owner, as it signifies compliance with safety standards.
Step-by-step explanation:
No person shall remove a leak test tag or notice from any refrigeration equipment unless they are authorized by the owner. The presence of a leak test tag implies that the equipment has undergone a specific inspection to detect any leaks that may present a risk to safety or the environment. Removing a test tag or notice without proper authorization could lead to serious safety violations, disregard for industry standards, or breach of laws and regulations governing the handling of refrigeration equipment.
Therefore, the correct answer to the question is (c) Authorized by the owner. Answers (a) It is torn, (b) It is illegible, and (d) It is Friday are not valid reasons for removing a leak test tag. The tag should only be removed by those with the proper authority to ensure that the equipment remains in compliance with safety standards until it is deemed appropriate to remove such notifications.
