Which item is the best example of a conductor?

An extension cord

True or False? Superficial burns, or thermal contact burns, are the result of heat generated by the flow of electric current through the body.

False

Which electrical safety control protects wiring and equipment by limiting the amount of current a circuit will carry and trips when the current flow becomes excessive and unsafe?

Fuses and breakers

Which electrical safety control is a device that shuts off an electric power circuit when it detects that current is flowing along an unintended path, such as through water or a person?

GFCI

Which electrical safety control provides an alternate path for current to flow through if a malfunction causes the metal frame of a tool to become energized?

Ground

Which electrical safety control involves a layer of non-conductive material on a tool where you typically touch it, like the handle?

Insulation

Which electrical safety control includes safety glasses to keep sparks out of your eyes and special non-conductive and anti-static footwear?

PPE

Which electrical safety control involves unplugging unused appliances, using power strips, and never overloading outlets?

Policies and procedures

If there is an electrical fire, which of the following responses should you NOT try?

Seal any doorways or windows to isolate the fire

If someone is not breathing after an electrical shock, which of the following responses should you NOT try?

Sit her up so she can breathe more easily

Which statement best describes a conductor?

Something physical, like copper, that electricity flows through easily

Which statement best describes an insulator?

Something physical, like rubber, that resists the flow of electricity

If someone is being electrocuted and can't let go of the conductor, which of the following responses should you

Spray her with water to cool her body and reduce burns

Which statement best describes an electrical circuit?

The flow of electrical current from, and back to, its power source

Which electrical safety control is an administrative control mandated by your employer to make sure you have the knowledge and skills to stay safe around electricity at work?

Training

True or False? If a victim is holding an electrocuting object, he might not be able to let go, causing violent contractions that can damage muscles, tendons, and ligaments, and may even break bones.

True

True or False? Internal injuries from electrical shock may not be immediately apparent to the victim or observers; however, left untreated, they can result in death.

True

True or False? Shock and fire are the two most common hazards associated with electricity on the job.

True

True or False? Ventricular fibrillation, respiratory arrest, or heart attack may occur with severe electrocution.

True

Which item is the best example of an electrical circuit?

Wiring that runs to and from a breaker box
