What is the purpose of a Master Sanitation Schedule (MSS) in relation to preventive maintenance?
Answer: It coordinates deep-cleaning tasks that complement equipment PM activities
The MSS schedules periodic deep-cleaning tasks that work alongside the PM program to keep equipment in food-safe condition.
A maintenance technician replaces a gasket on a pasteurizer. The replacement gasket is not listed as food-grade. What should happen next?
Answer: Stop production and replace with an approved food-grade gasket
Non-food-grade materials in product-contact areas must be replaced immediately to prevent chemical contamination.
Which maintenance strategy relies on sensor data and real-time monitoring to predict equipment failure before it occurs?
Answer: Predictive maintenance
Predictive maintenance uses condition monitoring (vibration, temperature, oil analysis) to forecast failure and schedule repairs proactively.
During a HACCP audit, the auditor reviews PM records for a metal detector. What would be a RED FLAG in those records?
Answer: Records are missing for three consecutive weeks
Gaps in metal detector maintenance and calibration records indicate the CCP control may not have been consistently verified, which is a serious finding.
A facility discovers that a chiller compressor has not been serviced per schedule because the work order was never generated. The ROOT CAUSE most likely relates to:
Answer: A failure in the PM scheduling or work order generation system
The failure to generate a work order points to a systemic breakdown in the PM planning or CMMS (computerized maintenance management system) process.
In food safety management, what does the term 'maintenance-induced contamination' refer to?
Answer: Contamination introduced during or after maintenance activities
Maintenance-induced contamination occurs when maintenance activities introduce physical, chemical, or biological hazards into food or food-contact surfaces.
Which of the following BEST describes the relationship between prerequisite programs (PRPs) and HACCP with respect to preventive maintenance?
Answer: PM is a PRP that supports HACCP by controlling general equipment-related hazards
Preventive maintenance is a core prerequisite program that manages hazards broadly, allowing the HACCP plan to focus on specific critical control points.
