- Remove any loose jewelry and secure long hair or neckties.
- Lift with your legs, not your back (bend at the knees when picking something up, not at the waist).
- Do not twist when lifting.
- Maintain the natural curves of the back and spine when lifting.
- Keep objects close to your body and at waist level.
- Push rather than pull if possible.

Properly dispose of solvents or cleaners (as well as their containers) used with computersat a local hazardous waste disposal facility.
Disassemble the machine and reuse the parts that are good.
Check out businesses that can melt down the components for the lead or gold plating.
Contact the Environmental Protection Agency (EPA) for a list of local or regional waste disposal sites that accept used computer equipment. The EPA’s web address is
