6 2007 Hazards of Electricity Arc Flash/Blast, Shock & Electrocution Shock & Electrocution: ELECTRICAL current passing through the human body is shock. Death due to shock is electrocution. A 120V, 60 Watt light bulb requires Amps of current (500mA), 50-80 mA will cause your heart to stop. At 15mA your muscles contract and you cannot let go. Thermal burns occur at exit and entry sites on the ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 ELECTRICAL Hazards. What has changed? In the past ELECTRICAL hazards were not given enough respect. Limited specific content in existing curriculum, ELECTRICAL SAFETY documents for companies, or nothing in place at all. Assumed the ELECTRICAL worker had it under control. Safe work permits didn t recognize the ELECTRICAL hazards appropriately, and operations staff didn t respect the ELECTRICAL hazards or felt the electrician would take care of it, he/she knew what they were doing.

7 Wrongly assumed that the ELECTRICAL worker was qualified and had the right tools, and PPE for the work ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 Case History Florida Commercial Building, Arc Flash The O/H power line contact hazard was identified, but no emphasis on the arc flash potential, just shock and electrocution. Limited to no specific guidance on electric arc flash, and contact ( shock or electrocution) with respect to energized ELECTRICAL equipment and circuit parts in Safe Work Permits (if used). No emphasis on requirement for detailed ELECTRICAL specific Job Hazard Assessment or detailed ELECTRICAL Safe Work ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 Case History Arc Flash in Florida Commercial BuildingWhat went wrong, was there a work plan, were the right tools and PPE used, was the second person qualified to be there?

8 Copyright ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 Case History Arc Flash in Food Processing PlantWhat went wrong, was there a work plan, were the right tools and PPE used, was the second and third person qualified to be there? Did they understand the potential risk? Could this incident have been avoided?Copyright ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 Case History High Voltage Shock, Paul HerbertPaul Herbert survived a 14,400V shock. He was a Power Linesman. Paul lost both of his legs, his right arm, fingers on his left hand and was burned at entry point. What went wrong, could Paul s incident have been avoided?Copyright ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 Better Management of ELECTRICAL Hazards ELECTRICAL SAFETY Program Can we make improvements in training, PPE and procedures.

9 YES WE CAN! Put down what you are going to do in writing. You need written documents. Recommended that you put all documents in a structured ELECTRICAL SAFETY Program (ESP). The ESP is included at part of your overall Occupational Health & SAFETY Management ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 Qualifications & Training More emphasis on this coming for ELECTRICAL workers. Neglected in the past? Qualifications, experience, competency, and evidence of the same required. Frequency of training, due diligence required. Non- ELECTRICAL workers will require more awareness ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 ELECTRICAL Specific PPE We know FR, but do you know what ATPV is? You will have to know now.

You will require the ELECTRICAL worker to have appropriate and approved ELECTRICAL specific ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 ELECTRICAL Safe Work Procedures May not of had these in the past, or not enough of them. Templated and site specific. Must be in writing, recorded and available for audit. Must ensure ELECTRICAL specific JHA. Use Energized ELECTRICAL Work Permit (EEWP) ESPS ELECTRICAL SAFETY Program Solutions INC. 2007 Changes in Engineering, Equipment, & Maintenance SAFETY By Design We can reduce the arc flash and shock hazard by engineering the risk of exposure to the hazards down. Focus on SAFETY first, then damage and reliability.
