Verify Zero: Try start (test) controls, meter/test for zero energy, check pressure/temperature gauges.
Communicate: Tell affected workers. Post status. Hand off only after group review and removal of personal locks by their owners.
Notes:
Use the written energy control procedure if one exists for this machine.
If energy cannot be fully isolated, use alternative controls approved by EHS.

Quick Reminders
Stay low if there’s smoke. Close doors behind you.
Don’t guess on chemicals—check the SDS.
If you feel unsafe: stop, step back, and call for help.
Stay ready. Fill this card, post it, and review it at the start of each shift.

About this course
This beginner-to-lower-intermediate course builds working knowledge of how modern vehicles operate across powertrain, chassis, braking, electrical, and electronic control systems. Emphasis on shop safety and HV awareness, proper tooling, torques, and use of service information. Cover engine fundamentals, fuel/ignition, engine management and closed-loop control; transmissions and drivelines; suspension, steering, tires, and basic dynamics; hydraulic brakes, ABS/ESC; 12V electrical, schematics, voltage-drop testing; OBD-II, CAN, data parameters; HVAC and cooling; emissions and aftertreatment. Develop practical skills in inspection, routine maintenance, and structured diagnostics: symptom mapping, test plans, and common fault patterns, plus ADAS and hybrid/EV awareness.
