Tech service bulletins, Shop manuals, and any other information applicable to the specific vehicle or components
you are working on.
Some safety issues to consider:
•
•
•
•
Be cautious around electricity. High voltage (enough to injure or kill you) is present on many vehicles. Ignition
systems, hybrid vehicles, and 42 volt electrical systems are just a few to be careful of.
Accidental deployment of the airbag system could happen if you inadvertently probe the wrong wire. Most
manufacturers use yellow colored wiring to denote wiring for the airbag system. Always be aware of the system/
circuit you are working on.
Always wear correct protective eyewear and clothing and use the appropriate safety equipment, as well as
fender covers, seat protectors, and floor mat protectors.
Make sure that you understand and observe all legislative and personal safety procedures when carrying out
practical assignments. If you are unsure of what these are, ask your supervisor/instructor.
