Final answer:
Dirty water from mop buckets should be disposed of properly to prevent contamination and the spread of harmful pathogens.
Step-by-step explanation:
Dirty water from mop buckets should be disposed of properly to prevent contamination and the spread of harmful pathogens. The water in mop buckets can accumulate dirt, bacteria, and other contaminants, making it unsafe for reuse or drainage into the regular sewage system. Instead, it should be poured into a designated area or drain that is separate from the regular plumbing system or treated with disinfectants.
