SAFETY MODEL STAGE 3—CONTrOLLING HAZArDS: SAFE WOrK ENVIrONMENT
Section 7 Safety Model Stage 3— Controlling Hazards: Safe Work Environment
How Do You Control Hazards?
In order to control hazards, you must first create a safe work envi- ronment, 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 NFPA 70E 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 pro- tect you from injury or death.
How Do You Create a Safe Work Environment?
❚ Guard against contact with electrical voltages and control electrical currents to create a safe work environment.
A safe work environment is created by controlling contact with elec- trical voltages and the currents they can cause. Electrical currents need to be controlled so they do not pass through the body. In addi- tion to preventing shocks, a safe work environment reduces the chance of fires, burns, and falls.
You need to guard against contact with electrical voltages and con- trol 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.
❑ Verify circuits are de-energized before starting work. ❑ 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.
