1. ELECTRICAL
WORK SAFETY
COURSE

2. WORKING NEAR
OF LIVE PARTS

3. WORKING NEAR OR LIVE PARTS
Common tasks where you need to work on or near live circuits
include:
• taking voltage and current measurements;
• opening and closing disconnects and circuit breakers;
• racking circuit breakers on and off the bus;
• removing panels and dead fronts; and
• opening electric equipment doors for inspection.

4. WORKING NEAR OR LIVE PARTS
Person working on energized equipment must be familiar with the following:
• Proper use of precautionary technique.
• Personal protective equipment.
• Insulating and shielding materials.
• Insulated tools.

5. WORKING NEAR OR LIVE PARTS
When working with energize circuits:
• Isolate the are from all traffic.
• Post signs and barricades.
• Use an attendant if necessary.
• Use insulated tool, mats and sheeting.
• Use electrical rubber sheeting to cover nearby exposed circuit.

6. WORKING NEAR OR LIVE PARTS
Conductive Materials/Equipment
• If an employee must handle long conductive objects, such as metal ducts, pipes, or rods in
areas with exposed live parts, then insulation, guarding, and/or approved materials handling
techniques must be used to minimize the hazard.
• Employees may not wear conductive articles of jewelry or clothing, such as watchbands,
bracelets, rings, key chains, necklaces, metal eye glass frames, metallic aprons, cloth with
conductive thread, or metal headgear, if they might contact exposed energized parts unless
they have been rendered nonconductive.

7. WORKING NEAR OR LIVE PARTS
Housekeeping
• Housekeeping duties may not be performed close to live parts unless adequate
safeguards, such as insulating materials or barriers are used.
• Electrically conductive cleaning materials, including steel wool, metallic cloth and silicon
carbide, as well as conductive liquid solutions may not be used near energized parts
unless procedures are followed to prevent contact.

8. WORKING NEAR OR LIVE PARTS
Interlocks
• Interlocks shall not be bypassed unless temporarily necessary as determined by the
qualified person working on the equipment.
• The work must comply with the specified procedures for working on or near exposed
energized parts.
• The interlock system must be returned to its operable condition when the work is
completed.

9. WORKING NEAR OR LIVE PARTS
Deenergized Parts
When employees work on deenergized parts or near enough to them to expose the
employees to any electrical hazard they present, the following safety related work practices
must be followed:
• Treat as energized any conductors and parts of electrical equipment that have been
deenergized but have not been properly locked out or tagged.
• While any employee is exposed to contact with parts of fixed electric equipment or circuits
which have been deenergized, the circuits energizing the parts shall be locked out or tagged
or both. In addition, electrical hazards must be controlled; a qualified person must test the
circuit to verify de-energization from all voltage sources.
• Safe procedures for deenergizing circuits and equipment must be determined before circuits
or equipment are deenergized.

10. WORKING NEAR OR LIVE PARTS
Hot Work on Electrical Equipment
A work permit should, at least, contain this information:
• a description of the circuit and equipment to be worked on and the location,
• explanation why the work must be done "live"
• date and time covered by the permit
• a description of the safe work practices to be used
• results of shock hazard analysis and determination of shock protection boundaries
• results of flash hazard analysis and determination of the flash protection boundary
• PPE needed to safely perform the job
• who will do the work and how will unqualified persons be kept away
• evidence of completion of job briefing, including discussion of job-specific hazards
• energized-work approval signatures (authorizing or approving management, safety officer,
etc.)
