According to safety regulations, what should individuals avoid on federal property?

Individuals should avoid creating hazards or littering on federal property because these actions can pose significant risks to safety and well-being. Creating hazards might involve leaving items that could cause trips, falls, or other injuries, while littering can attract pests, create environmental issues, and degrade the cleanliness and orderliness of the area. Safety regulations are in place to maintain a secure and functional environment for everyone who visits or works on federal property. Keeping the area clear of hazards and litter ensures a safe space for all and promotes responsible stewardship of federal lands.

The other choices do not present inherent dangers or violations of safety regulations in the same manner. Exchanging contact information, using public restrooms, and taking photographs (in designated areas and under specific guidelines) are actions generally permissible and do not compromise the safety or security of federal property.
