EES-101 Electrical Safety

What one strategy does OSHA mandate above all others with regard to minimizing the risk of injury from an electrical hazard?

The meter must be tested on a known voltage source both before and after it is used to verify de-energization.

At what voltage does OSHA establish that the voltage is high enough to pose a threat to a person if they make contact with energized parts?

At what current level does the heart run the risk of going into ventricular fibrillation?

The Occupational Safety and Health Administration was created by Congress in 1971 and serves a mission to:

OSHA is only concerned with electrical hazards within the workplace.

What special type of clothing are workers required to wear when performing energized tasks on high-power equipment, such as motor-control centers and switchgear?

What type of personal protective equipment is commonly worn by electricians to prevent shock when they must perform work on or near electrical equipment that has not been de-energized?

True or False: A properly installed and maintained GFCI will prevent an individual from experiencing any shock at all, if they contact a protected circuit.

AFCIs operate by monitoring the connected circuit for signs that electrical current is arcing between conductors in either a parallel or a series arcing fault or, as in the case with combination type, both series and parallel. In a series arc, how much of the circuit current is involved in the arc fault?
