Shock Hazard Analysis
Each year several hundred workers are killed as a result of inadvertent contact with energized
conductors. Surprisingly, over half of those killed are not in traditionally electrical fields (i.e.
linemen, electricians, technicians, etc.), but are from related fields such as painters, laborers, and
drivers. Recent investigations into the causes of these fatalities point to three principle causal
factors:
 Failure to properly or completely de-energize systems prior to maintenance or repair work;
 Intentionally working on energized equipment; and
 Improper or inadequate grounding of electrical system components.
These three factors form the basis for hazard analysis of the electrical shock hazard.
To appropriately assess the electrical shock hazard associated with any type of maintenance or
repair work, it is necessary to evaluate the procedures or work practices that will be involved.
These practices should be evaluated against both regulatory requirements and recognized good
practice within the industry. These principles are summarized below.
Regulatory Requirements
 All equipment must be placed in a deenergized state prior to any maintenance or repair work.
(Limited exceptions exist).
 The deenergized state must be verified prior to any work.
 The deenergized state must be maintained through the consistent use of locks and tags, and in
some cases, grounding.
 When energized work is performed, it must be performed in accordance with written
procedures.
Industry Recognized Good Practices
 Plan every job.
 Anticipate unexpected results and the required action for these results.
 Use procedures as tools.
 Identify the hazards. Keep unqualified workers away from these hazards.
 Assess employee’s abilities.
In addition to the assessment of work practices, a shock hazard analysis must include an
assessment of the physical condition of the electrical system.
