2.1.0 Safety Precautions
2.1.1 General Shop Safety
•
Keep workbenches and work areas clean. A clean workbench reduces the
chance of tool and parts falling from the bench onto the floor, where they could
be lost or damaged. A falling tool or part can land on your foot, causing injury. A
clean area reduces the possibility that critical parts will be lost.
•
Clean up spills before they are tracked around the shop. People are often injured
when they slip on floors coated with oil, antifreeze, or water. Gasoline spills can
be extremely dangerous because even the smallest spark can ignite the vapors,
causing an explosion or fire.
•
Make sure your work area is well lighted. Poor lighting makes it hard to see what
you are doing, leading to accidental contact with moving parts or hot surfaces.
Overhead light should be bright and centrally located. Portable lights, or
droplights, should be in proper operating condition. Droplight cages should be in
place. Always use a rough-service light bulb in incandescent droplights. These
bulbs are more rugged than normal light bulbs and will not shatter if they break.
Do not use a high-wattage bulb in a droplight. Light bulbs get very hot and can
melt the light socket or cause burns.
•
Never overload electrical outlets or extension cords by operating several
electrical devices from one outlet. Do not operate high-current electrical devices
through extension cords.
•
Inspect electrical cords and compressed air lines frequently to ensure that they
are in good condition. Also check for improper air hose connections. Do not close
vehicle doors on electrical cords or air hoses. Never run electrical cords in water
or in the rain. Should you in an emergency need to use electrical tools under wet
conditions, plug into a ground-fault circuit interrupter (GFCI).
•
Make sure all shop equipment, such as grinders and drill presses, are equipped
with the safety guards provided by the manufacturer. These guards should only
be removed for service operations, such as changing grinding wheels. Never
operate equipment without the proper guards.
•
When servicing any piece of equipment, be sure it is turned off and unplugged.
Closely monitor tool and equipment condition and make repairs when necessary.
This includes replacing damaged leads on test equipment, checking and adding
oil to hydraulic jacks, and regrinding tips on screwdrivers and chisels.
•
Never leave open containers of any liquids.
2.1.2 Floor Jacks and Jack Stand Safety
The pad must be positioned under an area of the vehicle's frame or at one of the
manufacturer's recommended lifting points. Your owner's manual will list safe jacking
points in a few different areas, but is usually included in the spare tire section.
Never place the lifting pad under the floor pan or under steering and suspension
components. These areas may look strong enough to hold a lot of weight but are not.
