Today, laboratories rely on a vast array of electrically powered equipment. To work safely with this equipment, employees need to understand how electricity works, be aware of common electrical hazards and know how to use electricity safely.

Atlantic Training’s "Electrical Safety in the Laboratory" training video program emphasizes the need for safety when using electricity, and discuss how to reduce the potential for accidents involving electrical shock, fire and explosions. Topics covered in these products include:

In many ways, electricity and water act very much alike. Water can be force through pipes by a pump and stored in a tank. Electricity can be force through wires by a generator and stored in a battery, whether standing or moving. The electromotive force cause by generators and batteries is really electrical pressure measured in units called volts when the switch is turned on and electricity begins to move, its rate of flow is called current measured in amperes. More electrical pressure, higher voltage usually causes more electrical current to flow higher amperage. Electrical pathways or wires tend to impede resist the flow of current, if the electrical pressure stays the same, the rate of current flow or amperage changes depending on the size of the wires. Circuit protection devices include fuses and circuit breakers, these electrical component protects against circuit malfunction by preventing too much current from passing from the power source through the rest of the circuit.
