One should not attempt to do what during an inadvertent oxygen mask drop?

During an inadvertent oxygen mask drop, it is essential not to repack the masks. This is primarily due to safety protocols and the importance of ensuring that the masks are available for immediate use in an emergency situation. Repacking the masks could lead to delays in accessing them, especially when quick response times are crucial for passenger safety. The masks are designed to be deployed quickly and efficiently, and tampering with them could jeopardize their functionality or create additional confusion among the crew and passengers.

In contrast, touching the mask, closing the compartment, or wearing the mask may be appropriate actions in specific contexts depending on the situation. However, the key concern during an inadvertent drop is to maintain the integrity and readiness of the oxygen systems, which is why repacking is strictly discouraged.
