An arc flash study is required by OSHA and the NFPA 70E to determine the risk level for all areas in which your employees perform work. This is essential to ensuring worker safety and helps save lives and money by minimizing the risk of injuries and lost time due to accidents.
Experience counts when conducting an arc flash study which is why people turn to the Professionals at Electrical Safety Specialists (ESS). We have a proven process for a turnkey, peace of mind arc flash solution that we will bring to your company anywhere in the United States.
ESS protocol for arc flash risk assessment includes the following:
- Data Collection: Collect necessary data about the facility’s power distribution system, including details of all three-phase electrical components, nameplate specifications and lengths, and cross-section of all cables.
- Short Circuit Analysis: Determine the available arcing fault current at every location required by NFPA 70E and IEEE 1584.
- Protective Device Coordination: Determine if overcurrent devices are properly coordinated with each other.
- Arc Flash Calculations: Determine incident energy levels and flash protection boundaries and complete calculations of all relevant equipment busses.
- Arc Flash Risk Assessment and Analysis Report: Once the calculations are done, a final report will be generated based on your facility’s existing conditions.
- Label Installation: Create and install warning labels pinpointing incident energy, working distance, arc flash boundary, and nominal system voltage. Including Limited and Restricted approach boundaries, date, and recommended personal protection equipment (PPE).
As part of a company’s safety protocols, an arc flash risk assessment provides insight into steps the employer must take to ensure that workers are protected. With the results of these studies, employers can follow the NFPA 70E steps of the hierarchy of controls to mitigate risk, labeling to raise awareness, provide training, and select the proper PPE for the job.
The study typically takes four to six weeks to complete, depending on the size of the facility. It is imperative that an arc flash study is completed before workers are exposed to electrical hazards.
An arc flash study should be completed every five years or any time a modification is made to the facility that may result in increased risk or severity of an accident.
ESS Arc Flash Engineering Technicians have extensive experience in commercial and industrial electrical installations and maintenance. They also have substantial training on the intricacies of the data collection process for an arc flash risk assessment. Our studies use 100% verified information via boots-on-the-ground information gathering. Our processes are detailed and thorough, ensuring that the integrity of our studies is the best in the business!
