Orientation, Site Safety Audit, and Shop Protocols

Welcome to the Externship

Your externship placement is where classroom knowledge becomes real-world skill. Before you touch a single piece of equipment, you have one non-negotiable priority: understand and follow the host shop's safety systems. This lesson walks you through the three tasks that must be completed within your first two scheduled days on site—site hazard identification, safety-document acknowledgment and lockout/tagout (LOTO) demonstration, and shadowing a complete customer work order.

Why the First Day Is a Safety Day

Professional shops run on routine, but hazards do not announce themselves to newcomers. Layout, equipment age, chemical storage habits, and emergency exit locations vary from shop to shop. An EETC-credentialed technician is expected to assess any new work environment before beginning work—this is not just good practice, it is the professional standard that employers across the industry expect.

Arrive on time, in your full PPE kit: ANSI-rated safety glasses, steel-toed boots, hearing protection, and nitrile gloves. Do not wait to be told to put them on. Wearing your PPE from the moment you step onto the shop floor signals professionalism and removes any ambiguity about expectations.

The Site Hazard Walkthrough

Your program-supplied hazard checklist organizes the walk into four zones. Work through each one with your site supervisor.

Electrical panels. Locate every panel box. Note whether the area in front of each panel is clear of at least the minimum required clearance (check the panel label and any posted requirements). Confirm panel doors close and latch. If a breaker is labeled "do not operate" or tagged out, record it.

Compressed-air lines. Trace the supply line from the compressor to each outlet. Look for cracked hose, corroded fittings, and missing whip-checks or safety clips at connections. Note the working pressure rating posted on the compressor tank. Confirm a pressure-relief valve is present and accessible.

Flammable-fuel storage. Identify where gasoline, mixed two-stroke fuel, and any other flammable liquids are kept. Containers should be approved safety cans with self-closing lids. Storage should be away from ignition sources and in a ventilated area. Note the location of the nearest ABC or BC fire extinguisher and verify that the gauge needle is in the green zone.

Lift and hoist areas. If the shop uses an engine hoist, floor jack, or equipment lift, check that rated-capacity labels are visible, safety pins or lock collars are present, and the floor beneath is free of oil that could cause slipping. Never work under a raised load that is supported only by a hydraulic jack—safety stands must be in place.

Record every observation in your externship log. The site supervisor will countersign the completed checklist. If you identify a genuine hazard during the walk, tell the supervisor immediately rather than simply writing it down and moving on.

Safety Documents, the Emergency Action Plan, and LOTO

After the walkthrough, you will review and sign three categories of documents:

1. Host employer's safety policy — your acknowledgment that you have read and understand the rules of the shop.

2. Emergency action plan (EAP) — exit routes, muster point, fire-extinguisher locations, and who to call for medical emergencies. Walk the exit routes physically; reading a map is not enough.

3. Shop-specific SOPs — procedures for tasks such as fuel draining, battery charging, and chemical disposal.

Immediately after reviewing these documents, you will demonstrate the shop's lockout/tagout procedure on one piece of equipment while the supervisor observes. LOTO exists to prevent unexpected energization—electrical, pneumatic, hydraulic, gravitational, or stored-spring energy—while a machine is being serviced.

The standard sequence is: Notify – Shut Down – Isolate – Apply Lock – Release Stored Energy – Verify. In practice this means: tell any affected workers the equipment is going out of service, shut it off using its normal controls, open or close the energy-isolating device (such as a disconnect switch or valve), apply your personal lock and tag, release or restrain any residual stored energy (capacitors, pressurized lines, raised parts), and verify the equipment cannot start by attempting to operate its normal controls. You must be able to perform this sequence without prompting before the supervisor signs off.

Shadowing a Complete Work Order

Once safety orientation is complete, spend time alongside an experienced technician following one customer work order from start to finish. Pay attention to four things:

• Write-up: How does the advisor gather customer complaints? What information goes on the work order at intake?
• Diagnosis and repair: How does the technician document findings, parts used, and labor time?
• Parts lookup: Whether the shop uses printed manuals, manufacturer portals, or a shop management system, note the steps the technician takes to confirm the correct part number for the machine's model and serial number.
• Customer communication: How is the completed repair explained, and what documentation is handed to the customer?

At the end of the day, write a one-page log entry summarizing what you observed. Use the required fields in your externship log binder: date, supervisor name, work order number (or description), skills observed, and your reflection on how classroom training connects to what you saw.

Mindset for the Externship

You represent your program and yourself. Ask questions when you are unsure—experienced technicians universally respect a student who asks rather than guesses. If you are ever asked to perform a task that seems unsafe, stop and speak up. No repair is worth an injury.
