Final answer:
Waste disposal containers for solid or liquid waste should be emptied weekly, whereas those for food waste need to be emptied daily. This helps maintain a sanitary workplace and prevents health hazards.
Step-by-step explanation:
In the context of maintaining a sanitary workplace, particularly in areas where food is handled, waste disposal protocols are crucial for health and safety. Waste disposal containers used for solid or liquid waste must be emptied weekly, but receptacles used for waste food must be emptied at least daily to prevent odors, pests, and the potential for illness that may arise from decaying organic material. It is important to ensure that the disposed materials are handled in accordance with public health guidelines; solids in the form of sludge may be processed in digesters, where they are kept for 20-30 days to reduce volume, odors, and destroy any harmful organisms. These solid wastes could then be utilized as fertilizers or sent to a landfill, depending on their composition and any potential dangerous contamination.
