9 Points Total (3 pts each)
Commercial Meat Slicer
Mandatory primary step:
Unplug electrical cord from wall and turn blade thickness dial to "0" before touching or disassembling parts.
Non-Stick Cookware
Tool restriction & alternative:
Steel wool destroys PTFE coating, creating toxic flakes (physical hazard). Use soft nylon pads or sponges.
Chemical Storage & PPE

9 Points (3 pts each: 1 pt hazard, 2 pts SOP)
Model Audit Findings (Accept any 3 of the following 4 major violations):
1 Hazard Identified: Used noon rag without disassembling slicer blade guard.
Corrective SOP:
Fully disassemble blade carriage; wash, rinse, and sanitize each part separately. Use a fresh, single-use sanitizing cloth from a newly mixed sanitizer bucket tested at proper PPM.
2 Hazard Identified: Oven cleaner applied without safety gloves; used dish sponge.
Corrective SOP:
Mandatory PPE (chemical-resistant rubber gloves & eye protection) required for caustic oven cleaners. Discard sponges (bacterial harborage/chemical erosion); use commercial scrubbing pads.
3 Hazard Identified: Wet-nesting sheet pans & storing degreaser above burger buns.
Corrective SOP:
Invert sheet pans individually on drying racks to air dry (prevent mold/bacteria). Relocate all cleaning chemicals to a designated chemical locker or bottom shelf below and away from food.
6 Points (3 pts each scenario)
The 4-Hour Rule Key
Mandatory 4-hour re-sanitizing:
Pathogen Bloom: Bacteria reproduce to dangerous thresholds within 4 hours at room temp (TDZ 41°F–135°F). Even if visually clean, microscopic bacterial biofilms form; FDA Food Code mandates full wash/rinse/sanitize every 4 hours of continuous use.
Unlabeled Bottle Key
OSHA protocol execution:
Immediate Quarantine: Remove bottle immediately from food zone. Never guess or smell contents. Notify chef/manager to verify and dispose of or label with chemical name, dilution, and hazard warnings per OSHA HazCom standard.
8 Points (Rubric Breakdown Below)
Master Exemplar Response:
Cleaning vs. Sanitizing: Cleaning removes physical soil and food films where microbes thrive. Sanitizing destroys biological pathogens (Salmonella, Norovirus, Listeria) that soap alone cannot kill.
Hazard Distinction: Physical hazards (loose steel wool fibers, glass) cause bodily injury; chemical hazards (unlabeled cleaners, toxic residue) induce poisoning; biological hazards (bacteria/viruses) cause foodborne illness.
Impact & Consequences: Contamination triggers illness outbreaks, hospitalization of vulnerable guests, mandatory health department closure, loss of food license, severe civil lawsuits, and business bankruptcy.
Scoring: Clear distinction (3 pts) • Hazard classification (3 pts) • Public health & legal impacts (2 pts)
