Proper Lifting Techniques
Back injuries are common in automotive repair.
Correct Lifting
Bend knees
Keep back straight
Lift with legs
Hold load close to body
Never
Twist while lifting
Lift beyond your capability
Lift awkward loads alone
Get assistance when necessary.
Exhaust Gas Safety

Before working:
Verify hood is:
Fully open
Properly supported
Failure can result in:
Head injuries
Hand injuries
Moving Vehicles
Vehicles can be extremely heavy.
Safety Rules
Use help when pushing
Use motorized pushers when available
Never push a vehicle alone if assistance is needed
Spontaneous Combustion
Definition
A fire that begins without an external flame source.
Occurs when:
Heat builds inside oily rags
Common causes:
Oil-soaked rags
Solvent-soaked rags
Prevention
Store rags in:
Approved metal containers with lids
Why?
Metal containers:
Limit oxygen
Prevent ignition
Electrical Safety
