Servicing Your Vehicle Safely
It is virtually impossible to anticipate all of the hazards involved with automotive
maintenance and service, but care and common sense will prevent most accidents.
The rules of safety for mechanics range from "don't smoke around gasoline," to "use the
proper tool for the job." The trick to avoiding injuries is to develop safe work habits and
take every possible precaution.
DO'S
Do keep a fire extinguisher and first aid kit handy.
Do wear safety glasses or goggles when cutting, drilling, grinding or prying, even if you
have 20-20 vision. If you wear glasses for the sake of vision, wear safety goggles over
your regular glasses.
Do shield your eyes whenever you work around the battery. Batteries contain sulfuric
acid. In case of contact with the eyes or skin, flush the area with water or a mixture of
water and baking soda, then seek immediate medical attention.
Do use safety stands (jackstands) for any undervehicle service. Jacks are for raising
vehicles; jackstands are for making sure the vehicle stays raised until you want it to come
down. Whenever the vehicle is raised, block the wheels remaining on the ground and set
the parking brake.
Do use adequate ventilation when working with any chemicals or hazardous materials.
Like carbon monoxide, the asbestos dust resulting from some brake lining wear can be
hazardous in sufficient quantities.
Do disconnect the negative battery cable when working on the electrical system. The
secondary ignition system contains EXTREMELY HIGH VOLTAGE. In some cases it can
even exceed 50,000 volts.
Do follow manufacturer's directions whenever working with potentially hazardous
materials. Most chemicals and fluids are poisonous if taken internally.
Do properly maintain your tools. Loose hammerheads, mushroomed punches and
chisels, frayed or poorly grounded electrical cords, excessively worn screwdrivers, spread
wrenches (open end), cracked sockets, slipping ratchets, or faulty droplight sockets can
cause accidents.
Likewise, keep your tools clean; a greasy wrench can slip off a bolt head, ruining the bolt
and often harming your knuckles in the process.
Do use the proper size and type of tool for the job at hand. Do select a wrench or socket
that fits the nut or bolt. The wrench or socket should sit straight, not cocked.
