Worksite Orientation and Expectations

Objective. The student will complete the employer's onboarding process, identify shop safety hazards and emergency procedures, and correctly execute the first supervised work order from intake to close-out.

⚠ Pending professional review

This lesson, its worked examples and its practice questions has not yet been verified by a credentialed professional in the field or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. 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.

Welcome to the Worksite

Your externship placement is where classroom knowledge becomes hands-on skill. On your first day, your primary job is not to fix appliances — it is to learn how this specific shop operates, where the hazards are, and how to move through a work order correctly. Every shop has its own rhythm, but the professional habits you build on day one set the tone for the entire placement.

Shop Safety: Know Before You Touch Anything

Before you handle a single tool, walk the shop with your supervising technician and locate the following:

Record every location in your placement journal the moment you find it. This is not busywork — in an emergency, memory fails and written notes do not.

Lockout/Tagout on the Shop Floor

Appliances on a repair bench can store energy even when unplugged: charged capacitors in microwave ovens can hold lethal voltage for minutes after the cord is pulled. The shop's energy-control procedure — commonly called lockout/tagout (LOTO) — tells you how to verify that stored energy is released before you open a unit. Follow the employer's written procedure exactly. If you are unsure whether a unit has been de-energized, ask your supervisor. There is no repair worth a shock.

Personal Protective Equipment

Wear the PPE the task requires:

The employer's onboarding packet and SDS binder will specify any additional requirements. Read the SDS for every chemical you use before first contact — the SDS is your primary reference for exposure limits, first-aid measures, and proper disposal.

Understanding the Work-Order System

A work order is the paper trail of every job. It begins the moment a customer brings in or calls about an appliance and ends when the job is closed out in the system. A properly completed work order typically includes:

1. Customer intake information — name, contact, appliance make/model/serial number, and the reported symptom in the customer's own words.

2. Diagnosis notes — what you found, the test results that confirm it, and the root cause.

3. Parts and labor — part numbers, quantities, labor time, and any warranty information.

4. Repair performed — a factual description of what was done.

5. Quality check — confirmation that the appliance was tested under normal operating conditions before release.

6. Close-out — technician signature, date, and any follow-up notes for the customer.

On your shadow shift, write your own notes alongside the supervisor's entries so you can compare. Ask questions between customers, not during them.

Your First Solo Work Order

Your first solo task will be low-complexity — something like replacing a worn door gasket or a burned-out oven igniter. Low-complexity does not mean low-stakes. The supervisor is watching your process, not just your result. Here is what a clean solo work order looks like in practice:

1. Read the intake notes carefully before touching the appliance.

2. Verify the reported symptom yourself — do not assume the intake description is complete.

3. Identify and control the energy source (unplug, discharge if needed, confirm).

4. Perform the repair using the correct tool for each step.

5. Test the appliance under normal operating conditions.

6. Complete every field in the work order form — no blank lines.

7. Hand the completed work order to the supervisor for review and signature.

If you discover a secondary problem during the repair, stop and notify the supervisor before proceeding. Unauthorized scope creep on a customer's appliance is a liability issue.

Professionalism Every Day

Professionalism during your externship is evaluated informally but continuously. Show up on time, wear your PPE without being reminded, keep your work area clean, and treat every customer's property with care. The PSA Certified Appliance Professional credential you are working toward is built on exactly these standards — competence, ethics, and accountability. Your supervising technician's signature on the orientation checklist is the first formal evidence that you are meeting them.

Key terms8

Lockout/Tagout (LOTO)An energy-control procedure that uses physical locks and warning tags to ensure equipment is de-energized and cannot be accidentally re-energized while a technician is working on it.
Work OrderA shop document that records all information for a single repair job, from customer intake through diagnosis, parts, labor, quality check, and final close-out.
Safety Data Sheet (SDS)A standardized document required by OSHA that provides hazard information, exposure limits, first-aid procedures, and safe handling instructions for a chemical product.
Customer IntakeThe first step of a work order in which the customer's contact information, appliance identification, and reported symptom are recorded before any diagnosis begins.
Quality CheckA final test performed under normal operating conditions after a repair is complete, confirming the appliance functions correctly before it is returned to the customer.
Refrigerant Recovery CylinderA DOT-approved pressure vessel used to capture refrigerant removed from a system during service; it must never be refilled beyond its marked safe fill weight.
Placement JournalA student-maintained daily log of observations, tasks completed, questions asked, and safety information gathered throughout the externship.
Close-OutThe final step of a work order in which the technician signs, dates, and submits the completed record, confirming all repair and quality-check steps are documented.
In class: Tour the shop with the supervising technician: locate fire extinguishers, eyewash station, first-aid kit, electrical panel, and refrigerant storage; record locations in the placement journal. · Review the employer's work-order software or paper system; shadow the supervisor on one complete job from customer intake and diagnosis through parts lookup, repair, and final quality check, taking written notes. · Complete the first solo work order under direct observation for a low-complexity task (e.g., replacing a worn door gasket or a burned-out oven igniter) and have the supervisor review and sign it.
Materials: Employer onboarding packet, shop safety data sheets, work-order system (software or paper), standard hand tools and multimeter, PPE kit, placement journal (student-maintained log), program externship handbook
Check: Supervisor signs the Orientation Checklist confirming the student located all safety equipment, completed site-specific safety acknowledgment, and closed out the first work order without errors; all boxes must be checked to pass.

Practice check8

Answer each question, then check it. Nothing is recorded; this is your own practice.
