SAFETY

Appropriate service methods and proper repair procedures are essential for the safe, reliable operation of all motor vehicles as well as the personal safety of the individual doing the repair. There are numerous variations in procedures, techniques, tools, and parts for servicing vehicles, as well as in the skill of the individual doing the work. This module cannot possibly anticipate all such variations and provide advice or caution to each. Accordingly, anyone who departs from the instruction provided in this module must first establish that he compromises neither his personal safety nor the vehicle integrity by his choice of methods, tools, or parts. The following list contains general warnings that should always be followed while working on a vehicle.

Always wear safety glasses for eye protection.
Use safety stands whenever a procedure requires underbody work.
Be sure the ignition switch is always off unless otherwise specified by a procedure.
Set the parking brake when working on the vehicle.
Operate the engine only in a well-ventilated area. Keep clear of moving parts when engine is running.
To prevent serious burns, avoid contact with hot metal parts such as the radiator, exhaust
manifold, tail pipe, catalytic converter and muffler.
Do not smoke while working on a vehicle.
