Recognizing and Mitigating Specific Hazards in the Work Place Encountered by the Non-Electrical Skilled Worker


It is developed as an add-on module to the basic electrical safety training module for non-electrical workers.
This training provides additional electrical safety training for electrical hazards non-electrical skilled workers are exposed to in the work place.
Non-Electrical Skilled Worker


Review of Basic Electrical Safety Hazard Awareness for the Non-Electrical Worker
  •   You should have taken as a prerequisite for this training “Basic Electrical Safety Hazard Awareness for Non-Electrical Personnel”.


v    This training covered the hazards associated with electrical energy – Shock, Arc and Blast.
Ø     These hazards can cause disability or death.
Ø     You were taught how to recognize electrical hazards.
 v    You were taught basic electrical safety that included:
Ø     Ground-fault Circuit Interrupters (GFCIs)
Ø     Basic electrical cord safety
Ø     Resetting Breakers
Ø     Conductive Apparel
Ø     Wall Penetrations
Ø     Safe Work Practices for Equipment Applications
Ø     Only qualified electrical workers can perform electrical work
 v     You were taught basic electrical safety that included:
Ø     What to do in case of an electrical emergency.
Ø     To inspect your work area for unsafe electrical conditions.
Ø     To use equipment per its Listing and Labeling instructions i.e. no daisy chaining, no overloading of circuits, etc.
Ø     What to do if you identify an electrical hazard.
Ø     To contact your Site Electrical Safety Officer or Safety Engineer for specific electrical safety items.
 v   The following list of workers includes but is not limited to those who would be considered a “Non-Electrical Skilled Worker”. 
Ø    Fitters, Painters, Carpenters, Laborers, Utility Operators, Equipment Operators, D&D Workers, Janitors, Radiation Control Technicians, Waste Handlers and Warehouse Workers.
 v   Non-Electrical Skilled workers are:
Ø    Exposed to specific electrical hazards
Ø    Expected to work safely around electrical energy
Ø    To use electrical tools safely
Ø    To follow electrical safety requirements
Ø    To help keep other workers safe from electrical hazards.
Ø    Obey all postings and barriers protecting exposed energized electrical hazards.

DOE and NFPA 70E Requirements
v   DOE has identified NFPA 70E (70E) as the basis document for electrical safety at its facilities.
v   Compliance with 70E is mandatory.
v   70E has specific requirements for working safely with electrical energy.

 v   Only Qualified Electrical Workers can perform work “ON” or “NEAR” electrical equipment 
v   Non-electrical workers may use electrical equipment, but must be trained to   know the hazards of the equipment and how to use the equipment safely.   
v   If you don’t know how to operate a piece of equipment safely and don’t know the hazards involved in it use, stop work and get the required training.  
v   70E requirements for energized work apply if an exposed energized condition exists.  
v   70E requires that an electrically safe work condition (Lockout/Tagout – LO/TO) must be established unless work around energized equipment with exposed electrical components is permitted with all the required safety precautions established.
 v   If an exposed energized condition exists, there will be a Flash Protection Boundary and a Shock Protection  Boundary that will have specific PPE and access requirements.
v   These boundaries are established to protect you from the heat energy of an arc and from getting shocked.
v   70E requires proper barriers, posting, and/or attendants to inform unqualified workers of existing hazards.
v   The work control document should address these boundaries and your work task relationship to them.
v   Do not cross these boundaries unless you are qualified and authorized or are escorted by a qualified electrical worker.
v   You must have the PPE required by 70E for the boundary to be crossed.
