What should be done after maintenance activities on equipment?

• A. Left as is
• B. Affected equipment and surroundings must be cleaned and sanitized
• C. Only the equipment needs cleaning
• D. Only the surroundings need cleaning

Answer: (B)

After maintenance, both the equipment and the surrounding area must be cleaned and sanitized. Maintenance work can leave residues, lubricants, dust, metal shavings, or tool marks that could contaminate product or harbor microorganisms. Cleaning removes soils and debris, while sanitizing reduces microbial load to safe levels, ensuring the equipment can be used without risk. Cleaning only the equipment misses possible contamination on floors, drains, and nearby surfaces, and cleaning only the surroundings might leave residues on the equipment itself. Leaving it as is would leave contaminants that could compromise product safety.
