A COMPLETE ELECTRICAL RISK ASSESSMENT METHOD FOR ALL ELECTRICAL HAZARDS AND ITS APPLICATION
To address the hazards, risks, and controls of
electrical work in all fields, recent efforts in classifying all
electrical shock hazards and all arc flash hazards are
presented in an approach to perform risk assessments and
develop controls for all forms of electricity in all work
environments. This presentation considers recent efforts in
NFPA 70E, Department of Energy, and Department of Defense
to address electrical hazards beyond power frequencies (50/60
Hz) in electrical systems and equipment including battery
banks, solar and wind power systems, DC transmission lines,
lasers, accelerators, capacitor banks, electroplating systems,
induction and dielectric heating systems, etc. Industries
utilizing these non-power frequency electrical hazards include
chemical, power generation and transmission, aluminum and
steel, military, and research.
Recent work in the classification of all shock hazards and all
arc flash hazards will be used to take the thresholds for various
types of injuries and present a method of performing risk
assessments based on energy type, work task, exposure,
equipment configuration and condition, environmental
considerations, and worker knowledge, experience, training and
condition. This approach to risk assessment for electrical work
with all electrical hazards in all work environments will then be
used for the controls to prevent injury, including Personal
Protective Equipment (PPE), training, oversight, and co-worker
responsibilities.
This paper presents a method of risk assessment for
electrical work considering potential exposure to all forms of
electricity, in all electrical work environments, for all industries.
This risk assessment approach will include traditional AC
power, DC, impulse, and radiofrequency sources.
