CHA Preventive Maintenance Procedures 3

Question 1

What is the purpose of a Master Sanitation Schedule (MSS) in relation to preventive maintenance?

Accepted Answer

It coordinates deep-cleaning tasks that complement equipment PM activities

Answer

The MSS schedules periodic deep-cleaning tasks that work alongside the PM program to keep equipment in food-safe condition.

Question 2

A maintenance technician replaces a gasket on a pasteurizer. The replacement gasket is not listed as food-grade. What should happen next?

Accepted Answer

Stop production and replace with an approved food-grade gasket

Answer

Non-food-grade materials in product-contact areas must be replaced immediately to prevent chemical contamination.

Question 3

Which maintenance strategy relies on sensor data and real-time monitoring to predict equipment failure before it occurs?

Accepted Answer

Predictive maintenance

Answer

Predictive maintenance uses condition monitoring (vibration, temperature, oil analysis) to forecast failure and schedule repairs proactively.

Question 4

During a HACCP audit, the auditor reviews PM records for a metal detector. What would be a RED FLAG in those records?

Accepted Answer

Records are missing for three consecutive weeks

Answer

Gaps in metal detector maintenance and calibration records indicate the CCP control may not have been consistently verified, which is a serious finding.

Question 5

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:

Accepted Answer

A failure in the PM scheduling or work order generation system

Answer

The failure to generate a work order points to a systemic breakdown in the PM planning or CMMS (computerized maintenance management system) process.
