Electrical Safety NFPA 70E
Electrical Safety NFPA 70 EHow Electricity Works Operating an electric switch is like turning on a water faucet. Behind the faucet or switch there must be a source of water or electricity with something to transport it, and with a force to make it flow. In the case of water the source is a pump, and the force to make it flow through the pipes is provided by the pump. For electricity, the source is the power generator. Current travels through Electrical conductors (wires) and the force to make it flow, measured in volts, is provided by a Electrical Terminology Current: the movement of Electrical charge Resistance: opposition to current flow measured in ohms Voltage: a measure of Electrical force Conductors: substances, such as metals, that have little resistance to electricity Insulators: substances, such as wood, rubber, glass, and bakelite, that have high resistance to electricity Grounding: a conductive connection to the earth which acts as a protective measureDangers of Electricity On average, a worker is electrocuted every day Causes 12% of young worker workplace deaths Takes very little electricity to cause harm Significant risk of causing firesEffects on the Human Body 1 mA: Can b
