Safe Work Environments
Controlling Hazards
In order to control hazards, you must first create a safe work environment, then work in a safe manner.
Generally, it is best to remove the hazards altogether and create an environment that is truly safe. When OSHA regulations and the NEC guidelines are followed, safe work environments are created.
Creating a Safe Work Environment
A safe work environment is created by controlling contact with electrical voltages and the currents they can cause. You need to guard against contact with electrical voltages and control electrical currents in order to create a safe work environment. 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.
