What safety measures should a mail clerk observe when handling mail?

Using gloves when necessary and avoiding the opening of damaged packages is a crucial safety measure for a mail clerk because these practices help prevent physical harm and exposure to potentially hazardous materials. Gloves provide a barrier between the skin and any substances that may be present on the mail, such as chemicals, sharp edges, or infectious agents. This minimizes the risk of cuts, infections, or contamination.

Additionally, avoiding damaged packages is essential because they may contain dangerous items or substances that could have leaked or spilled. By not opening these packages, mail clerks protect themselves from possible injuries or exposure to harmful materials. This precaution aligns with safety protocols designed to ensure the well-being of employees in environments where handling various items is routine.

The other options are not suitable as safety measures in this context. For example, wearing sunglasses and ear protection might not be relevant to the typical duties of a mail clerk, and stacking packages excessively high can create hazards rather than mitigate them. Handling parcels without any protective gear contradicts the fundamental safety practices necessary in the handling of mail.
