Which document is most critical for establishing a preventive maintenance (PM) schedule in a HACCP-regulated food facility?
Answer: Equipment manufacturer's maintenance manual
The manufacturer's maintenance manual specifies recommended service intervals and procedures that form the foundation of a PM schedule.
A food plant uses food-grade lubricants on equipment that contacts product. What is the PRIMARY reason for this requirement?
Answer: Incidental contact with food will not create a safety hazard
Food-grade lubricants (e.g., H1 classification) are formulated so that incidental food contact does not pose a health risk.
After completing a maintenance task on a filler machine, which step is MOST important before resuming production?
Answer: Perform a pre-operational sanitation inspection
A pre-operational sanitation inspection ensures that tools, debris, and non-food-grade materials are removed before food production resumes.
In HACCP terminology, a piece of equipment malfunction that could allow metal fragments into product would be classified as a:
Answer: Potential physical hazard at a CCP
Metal fragments from faulty equipment constitute a physical hazard that must be controlled, often at a designated CCP such as a metal detector.
A facility's PM program requires monthly belt inspection on a conveyor. An auditor finds the last inspection was performed 47 days ago. This is BEST described as:
Answer: A deviation requiring corrective action documentation
Missing a scheduled PM interval is a deviation from the program that must be documented and corrected per the facility's procedures.
Which element should be included in a PM work order to support HACCP traceability?
Answer: Date, equipment ID, parts used, and technician signature
Traceability in PM records requires identifying when work was done, on which equipment, what materials were used, and who performed the work.
When scheduling preventive maintenance during production hours is unavoidable, what control is MOST important to implement?
Answer: Isolate or segregate the maintenance area to prevent product contamination
Physical isolation of the maintenance zone prevents tools, lubricants, and debris from contaminating product moving through adjacent areas.
