People who work in some jobs risk exposure to high voltage electricity.
People who work with electricity have a variety of safety wear or PPE, that they put on to work in certain places.
Insulators are used in many places in our daily lives to protect us from the dangers of electricity.
Scientists and engineers in industry test, design and make new and improved materials and products.
Lightning rods can be used to protect buildings from lightning strikes.

Electrical insulators cannot conduct electricity at all.

Children will be taught that electrical insulators are materials that do not allow electricity to pass through them easily.

Electric shock - An electric shock occurs when electricity passes into our bodies. It can be very dangerous.
High voltage - High voltage electricity flows with a stronger push than low voltage electricity.
Personal protective equipment - Personal protective equipment or PPE refers to clothes and equipment used by people to keep them safe.
Electrical insulator - An electrical insulator is a material that does not allow electricity to pass through it easily.
Electrical conductor - An electrical conductor is a material that allows electricity to pass through it easily.
