the path of electrical current must make a complete one of these in order for current to flow.
What is a loop
200
This symbol can be identified by using a bolt or a bolt through a hand, which lets people know that injury or death can occur from nearby high-voltage electrical equipment.
What is Voltage or Shock Hazard Symbol
300
This is a substance that can pass electricity
What is conductors
300
this is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
What is a circuit breaker
300
This should have lock out capabilities for both AC and DC circuits
What is Switchboard
300
Most industrial and domestic use of electricity is supplied bby AC current
What is current
300
If you see a lightning bolt on the bottom of a shoe, then you know that there is a danger of an explosion occurring from static electricity.
What is Static Hazards
400
When These travels through our bodies, it can interfere with the normal electrical signals between the brain and our muscles
What is electrical currents
400
when working with power tools The grounded equipment must have an approved 3-wire cord with a 3-prong plug. This plug should be plugged in a properly grounded one of these
What is 3-pole outlet.
400
These must have approved voltage and ampere ratings, comparable with their intended use
What is a Switch
400
The electric arc that is an electrostatic discharge
What is spark
400
Severe burns, haemorrhages, destruction of tissues, nerves and muscles are examples of what injury?
What is Internal Injuries
500
Thermal burns from the heat radiated from an electric arc flash. Ultraviolet (UV) and infrared (IR) light emitted from the arc flash can also cause damage to these parts of the body
What is eyes

Risk of electric shock is greater in areas that are wet or damp. Install these (GFCIs) as they will interrupt the electrical circuit before a current sufficient to cause death or serious injury occurs.
What is Install Ground Fault Circuit Interrupters
500
the measure of the AMOUNT of electricity used.
What is Amperage
500
Can jump the air gap between the conductors and ignite combustible gases or dusts.
What is electrical arc
