1. An electric shock is a physical sensation caused by the reaction of the nerves to electricity.
2. The danger of severe shock is greatly increased if the skin becomes wet.
3. In addition to shock, an excessive current through any part of the body can cause severe burns.
4. Electrical wires, wherever they may be found in a circuit, should always be treated as being potentially dangerous.
5. It is always safe practice to read and thoroughly understand all available operating instructions supplied with electrical and electronic products.
6. You should make it a habit to periodically inspect all electrical and electronic equipment you use.
7. A plug-in device should be immediately unplugged if it does not seem to be working normally.
8. An Underwriter's Laboratories label on a product shows that it has been made according to strict safety standards.
9. Putting any part of your body between the ground and a live wire presents the danger of severe shock.
10. A grounding wire is used to prevent a shock hazard from existing between a metal cabinet and your body.
11. Grounding plugs and outlets automatically connect power cords to the building ground.
12. The color of the grounding wire in the power cords of tools and appliances is green.
13. The use of double, or reinforced, insulated products significantly lessens the danger of severe electric shock.
14. A fuse is a safety device that works as a switch to turn a circuit off when there is too much current.
15. When a circuit becomes overloaded, it becomes overheated.
16. The electrical size of an ordinary plug fuse is given in amperes.
17. Dual-element fuses are usually needed in motor circuits.
18. Never replace a fuse of the proper size with a larger one.
19. A is a mechanical device that, like a fuse, protects a circuit from excessive current.
20. Ground-fault circuit interrupters sense the difference between the currents in the hot and neutral wires.
21. OSHA stands for Occupational Safety and Health Act.
