Electrophoresis equipment may be a major source of electrical hazard in the laboratory. The presence of high voltage and conductive fluid in this apparatus presents a potentially lethal combination.

Many people are unaware of the hazards associated with this apparatus; even a standard electrophoresis operating at 100 volts can deliver a lethal shock at 25 milliamps. In addition, even a slight leak in the device tank can result in a serious shock.

Protect yourself from the hazards of electrophoresis and electrical shock by taking these precautions:

1. Use physical barriers to prevent inadvertent contact with the apparatus.
2. Use electrical interlocks.
3. Frequently check the physical integrity of the electrophoresis equipment.
4. Use warning signs to alert others of the potential electrical hazard.
5. Use only insulated lead connectors.
6. Turn the power off before connecting the electrical leads.
7. Connect one lead at a time using one hand only.
8. Ensure that your hands are dry when connecting the leads.
9. Keep the apparatus away from water and water sources.
10. Turn the power off before opening the lid or reaching into the chamber.
11. Do not disable safety devices.
12. Follow the equipment operating instructions.
