615 Electrical Safety - Hazards and Controls
Skip to main content

Controlling Hazards

To control hazards, you must first create a safe work environment, then work in a safe manner.

Be sure your circuits are grounded.

Generally, it is best to remove the hazards altogether and create an environment that is truly safe. When OSHA regulations and the NEC are followed, safe work environments are created.

But, you never know when materials or equipment might fail. Prepare yourself for the unexpected by using safe work practices. Use as many safeguards as possible. If one fails, another may protect you from injury or death.

Creating a Safe Work Environment

A safe work environment is created by controlling contact with electrical voltages and the currents they can cause. Electrical currents need to be controlled so they do not pass through the body. Make your environment safer by doing the following:

  • Treat all conductors - even de-energized ones - as if they are energized until they are locked out and tagged.
  • Lock out and tag out circuits and machines.
  • Prevent overloaded wiring by using the right size and type of wire.
  • Prevent exposure to live electrical parts by isolating them.
  • Prevent exposure to live wires and parts by using insulation.
  • Prevent shocking currents from electrical systems and tools by grounding them.
  • Prevent shocking currents by using GFCIs.
  • Prevent too much current in circuits by using overcurrent protection devices.
