Workplace Safety
Adapt this list of reminders to your working environment. Be sure to consider
company policies and local, state, and Federal codes before establishing a
written electrical safety program.
Plan every job and think about what could go wrong.
Use the right tools for the job.
Use procedures, drawings, and other documents to do the job.
Isolate equipment from energy sources.
Identify the electric shock and arc flash, as well as other hazards that may
be present.
Minimize hazards by guarding or establishing approach limitations.
- Test every circuit and conductor before you touch it.
- Use personal protective equipment (PPE) as a last line of defense in case something
goes wrong.
- Be sure you are properly trained and qualified for the job.
- Work on electrical equipment and conductors only when deenergized, unless procedures
and safeguards have been established to ensure zero exposure for the worker
and other people in the area.
- Lockout/tagout and ground (where appropriate) before working on equipment.
- Treat deenergized electrical equipment and conductors as energized until lockout/tagout,
test, and ground procedures (where appropriate) are implemented.
- Wear protective clothing and equipment and use insulated tools in areas where
there are possible electrical hazards.
- Deenergize and visibly guard (where possible) whenever contact with uninsulated
overhead power lines is possible.
- Check and double check safety regulations when a ladder or parts of any vehicle
or mechanical equipment structure will be elevated near energized overhead
power lines. Call your local electric utility for assistance. People standing
on the ground may be particularly vulnerable to possible injury.
Cords, Equipment and Tool Grounding
- Protect flexible cords and cables from physical damage. Check cords for
cut, broken, or cracked insulation.
- Keep slack in flexible cords to prevent tension on electrical terminals.
- Make sure the insulating qualities of a splice are equal to or greater
than the original cord.
- Extension cords are for temporary use. Install permanent wiring when
use is no longer temporary.
- Verify that all three-wire tools and equipment are grounded.
- Verify that all three-wire tools and equipment are grounded.
- Ground exposed parts of fixed equipment that could be energized.
- Use non-conductive tools whenever possible.
- Always double check the operation of your voltage testers by testing
a live circuit.
Other Considerations
- Verify location of all buried or embedded electrical circuits before
digging or cutting.
- Determine the reason that a fuse operated or circuit breaker tripped
before replacing or resetting.
- Know where your overcurrent devices are (i.e. circuit breakers and fuses)
so they can be easily and quickly reached in case of emergency.
- When replacing lamps and bulbs, verify that the replacement matches
fixture requirements.
