Process Equipment, Utilities and Facility Safety
What the exam tests
Utility quality, equipment design and maintenance, facility layout, and segregation that prevent contamination.
Core rules
- Potable water for food contact and handwashing; backflow prevention; no cross-connections.
- Culinary steam must be safe, filtered, and free of toxic boiler additives; test for carryover.
- Compressed air that contacts food must be oil-free, dry, filtered, and monitored.
- Facility zoning separates raw from ready-to-eat; airflow and drainage flow away from high-care; floors slope to drains; no ponding.
- Maintenance tools, lubricants, and spare parts are contamination sources; control them.
Worked example
Compressed air blows crumbs off a RTE line. An air test shows oil carryover. Corrective action: install a coalescing filter and dryer, relocate the blow-off, retest at the point of use, and add a preventive maintenance task. The hazard is chemical and microbiological (oil and condensate).
Traps
Using plant steam directly on food; dead legs in water lines; positive pressure from raw to RTE; neglecting drain odors and flies; unapproved lubricants.
