Arc Flash Risk Assessment (Study)
The National Fire Protection Association Guidelines (NFPA 70E) require facility owners to perform an arc flash risk assessment prior to allowing a worker or contractor to perform a task on energized equipment. The arc flash risk assessment identifies the presence and location of potential hazards and provides recommendations for PPE, boundaries for limited and restricted approaches, recommendations for flash protection, and safe work practices.
Arc Flash Hazard Labeling Plan
Electrical inspectors are now enforcing the new labeling requirement published in the National Electrical Code (NEC 110.16) that states a warning label must be placed on electrical equipment that may remain energized during maintenance or repair. ERS can assist with compliance during each phase of an arc flash risk assessment. In the initial phase, ERS supplies the labels and can also assist in applying the appropriate warning labels and signs.
Site Review / Compliance Assessment
The Occupational Health and Safety Administration (OSHA) is diligent in enforcing the NFPA 70E Guidelines. To ensure compliance ERS can determine the necessary steps to fulfill the more general statements in the OSHA standards. We conduct a comprehensive assessment at your facility to identify areas of risk and non-compliance. A plan is then formulated to bring your facility into compliance in the most efficient way possible.
ERS' technical staff can conduct a design review of your electrical distribution system to identify areas to reduce potential arc flash hazards. Several areas are evaluated including fault levels, exposure times, remote operations, remote racking, and system grounding. Employing special devices and altering current design can significantly reduce fault levels, arcing time, arc incident energy, and arc blast force. Conducting a design review is the most effective way to uncover potential hazards so these types of solutions can be employed.
NFPA 70E requirements mandate accurate, up-to-date single-line diagrams. These documents are essential for documenting, troubleshooting, and communicating information about your power systems. To meet these requirements, ERS can conduct a comprehensive site survey that is essential to develop or to update existing single-line diagrams or complete electrical system drawings.
Short Circuit and Coordination Studies
Arc Flash calculations should be completed in conjunction with short circuit calculations and protective device coordination to achieve the most accurate Arc Flash Hazard results. Short circuit and coordination studies verify protective devices and arc hazard ratings, calculate momentary interrupting and relay currents, establish settings for all types of protective devices, and coordinate your entire power distribution system to minimize downtime. ERS specializes in conducting these studies that provide critical information you need to ensure compliance with NFPA and OSHA requirements.
ERS can assist in developing a preventive maintenance program to specifically address arc flash hazards. Our optimized preventive maintenance program evaluates the equipment’s condition and determines the most cost-effective and manageable solution to ensure your protective devices operate properly, safely, and reliably–eliminating prolonged exposure to arc flash, which could result in disabling injuries or death.
An effective arc flash training program should provide workers the knowledge and understanding of the existence, nature, causes, and methods to prevent electrical hazards. ERS' arc flash training program includes training on arc flash awareness, standards and codes, understanding of arc flash quantities, selection and use of appropriate PPE, reading and following warning signs and labels, methods to reduce risk while working on live exposed parts, arc flash hazard assessment, and documentation.
Personal Protective Equipment Plan
ERS' Personal Protective Equipment Plan addresses all OSHA standards regarding PPE to ensure compliance. Based on the findings of the arc flash analysis, ERS will provide PPE category requirement and recommendations. We can also assist in the selection and supply of recommended equipment on which workers will be trained. Our team will address when the PPE is necessary and what equipment is needed. ERS' approach covers how PPE should be worn, maintained, and disposed of after the equipment life has expired.
Proper documentation ensures compliance with OSHA and NFPA standards and facilitates investigation should an arc flash related injury occur. Thorough documentation is one of ERS' strengths. Our arc flash compliance plan consists of a customized written report that includes the result of the arc flash analysis, updated single-line drawings on electrical systems, signs and labels on equipment and hazardous areas. Also included in the documentation are the type, name/ID, incident energy at working distances, flash protection boundary, hazard/risk category, and other pertinent information such as voltage, available fault current, protective device description and its trip time, arc gap, and current. Documentation can also be provided as part of the safety program and documentation of training provided to workers.
