Technician Safety Information


BLOCK DRIVE WHEELS
Block the drive wheels as a safety precaution, before beginning any service with the vehicle on the ground.

SUPPORT THE VEHICLE
Never work under a vehicle supported only by a jack. Use jackstands, on a flat and level hard surface, for safe support.

EYE PROTECTION
Always wear appropriate eye protection.

CATALYTIC CONVERTORS
Use caution when working near the catalytic convertor to prevent the possibility of burns. The temperatures within the convertor can exceed 650° C (1200° F).
The catalytic converter routinely reaches operating temperatures of 650° C (1200° F) and will stay hot for some time after the engine has been shut off. Do NOT park the vehicle over any object or material that could ignite (i.e. dry leaves, cardboard, puddles of oil, or other combustibles).

CARBON MONOXIDE
Exhaust gas contains toxic carbon monoxide. Do not run the engine in confined areas or breathe concentrated exhaust gases. Breathing exhaust gases may cause loss of consciousness or even death.

EXHAUST SYSTEM LEAKS
Repair any leaks in the exhaust system as soon as possible. Hot gases escaping from the leak can ignite flammable materials and may set the vehicle on fire.
Also, exhaust may circulate through the passenger compartment causing throat, sinus, and eye irritation, light headedness, headaches, and increased irritability, especially while driving with windows closed.

FUEL ODORS / EXCESSIVE EMISSIONS
Be alert for fuel odors and excessive tailpipe emissions (black smoke etc.). These are problem indicators.
