Objective. Students will independently execute the full sterile processing cycle for an assigned instrument set in the program's simulated department, completing every required documentation form accurately and responding correctly to at least three instructor-injected workflow failures.
This lesson, its worked examples and its practice questions has not yet been verified by a licensed clinician in the field or by a certification or approval body. It is a study draft and may contain errors. Do not use it to make decisions about any patient or medication. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
This lab brings together every skill you have practiced in this program. You will move a soiled instrument set through the complete sterile processing cycle from start to finish—cleaning, inspection, packaging, sterilization, and storage—while documenting each action in real time and responding to unexpected failures along the way. Strong performance here demonstrates you are ready to work safely and independently in an actual sterile processing department (SPD).
Your first action every time you enter the decontamination area is to don full personal protective equipment (PPE): fluid-resistant gown, surgical-grade mask, face shield, and gloves rated for the chemicals and biological hazards present. PPE must be in place before you touch any soiled item—no exceptions. This is a critical safety step on your competency checklist, meaning a single failure to don PPE correctly before handling soiled instruments requires you to repeat the entire decontamination phase. Contaminated instruments carry bloodborne pathogens, and your personal safety and the safety of your coworkers depend on this discipline every shift.
When you move from the decontamination area to the clean/prep-and-pack area, remove and dispose of decontamination PPE, perform hand hygiene, and don fresh gloves before handling any clean items. Cross-contamination between zones undermines the entire sterile processing chain.
Pre-cleaning and mechanical washing. Begin with manual pre-cleaning: rinse gross soil under cold water, scrub lumens and joints with appropriately sized brushes, and follow your facility's enzymatic detergent concentration and soak time. Load the washer-disinfector according to the manufacturer's instructions—hinged instruments open, heavy items on the lower rack, and nothing blocking spray arms. Unload when the cycle is complete and inspect each tray before moving it forward.
Inspection. Every instrument must be inspected under a light source with magnification loupes. Check for residual soil, corrosion, pitting, cracks, and proper function (box locks move freely, scissors cut cleanly, tips align). Record failures on the inspection log. A wet pack discovered at this stage—visible moisture inside a wrapped tray—is a contamination event: the item must be reprocessed. Never pass a wet pack to sterile storage.
Assembly and packaging. Reassemble instrument sets per the count sheet, apply tip protectors to sharps, and select the correct packaging material for the sterilization method. Place a Class 4 chemical indicator inside each package and, where required by your department, a Class 5 integrator. Seal pouches so the seal is complete with no channels or wrinkles; wrap trays using the square-fold or envelope-fold technique, ensuring all folds are secure. Record lot number, date, sterilizer number, and cycle on each package label.
Sterilizer loading and indicators. Load the sterilizer with packages positioned to allow steam or sterilant contact on all surfaces—do not overcrowd, do not place pouches flat on top of wrapped packs. Place a biological indicator (BI) in the most challenging location within the load (typically the front, bottom, near the drain). A control BI from the same lot must be incubated simultaneously but not processed, to confirm the test system is working. Initiate the cycle only after verifying that cycle parameters (temperature, time, pressure or concentration) match the load type.
BI incubation and load release. Incubate the processed BI and the control BI together in the incubator at the manufacturer's specified time and temperature. A negative (no growth) processed BI combined with a positive (growth) control BI confirms sterilization process performance and permits load release—provided all chemical indicators also show a satisfactory result and the physical printout confirms correct parameters were reached. Document results on the load record immediately.
Sterile storage and inventory. Transfer released items to sterile storage on clean, dry, covered shelving. During your inventory count, check every package for expiration date or event-related integrity issues: torn wrap, broken seals, moisture, or soil. Any suspect package must be removed and flagged. Reconcile counts against the par-level sheet and complete a requisition for items below par. Report findings verbally to the instructor as a brief summary, as you would to a charge technician.
At three unannounced points the instructor will introduce a deliberate failure. Your job is to recognize it, stop the affected work, and act correctly:
In every case, complete an incident report form fully before you continue. Thorough documentation protects patients, supports root-cause analysis, and is a professional and regulatory expectation.
Every action you take must be recorded in real time on the appropriate form—load record, inspection log, or incident report. Fields left blank, illegible entries, or corrective fluid are not acceptable. If you make an error on a paper form, draw a single line through it, initial, and date the correction. Accurate, complete records are the legal evidence that safe sterile processing occurred.
Answer each question, then check it. Nothing is recorded; this is your own practice.
