Arc Flash Risk Assessment Can Save Lives And Minimize Risk
Arc flash risk assessment can help save lives and minimize the possibility of injuries and lost time accidents. This assessment is required by OSHA and the NFPA 70E to determine the risk level for all areas in which your employees perform work.
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 to eliminate or substitute de-energization, use labeling to raise awareness, provide training, and select the proper equipment 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 major modification is made to the facility that may result in increased risk or severity of an accident.
Electrical Safety Specialists (ESS) 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.
- Engineering Analysis of the Data: Perform a short circuit analysis followed by a coordination study and feed the data into NFPA 70E equations to determine the minimum PPE requirement.
- Protective Device Coordination: Coordinate PPE to ensure selection and arrangement are sufficient for mitigating arc flash hazards.
- Arc Flash Calculations: Determine incident energy levels and flash protection boundaries and complete calculations of all relevant equipment busses.
- Arc Flash Study and Analysis Report: Once the calculations are done, deduce the results of the report carefully.
- Label Installation: Create and install warning labels pinpointing incident energy and working distance, arc flash boundary, and nominal system voltage. Include Limited and Restricted approach boundaries, date, upstream protective device, and recommended personal protection equipment (PPE) as well.
