Arc Flash Hazard Analysis / Risk Assessment

  1. What are the steps involved in Arc Flash Analysis? A. Arc Flash Hazard Analysis or Risk Assessment is a study conducted by trained safety experts to analyze electric equipment and power systems in order to predict the amount of incident energy from an arc flash. According to IEEE std 1584, there are 9 steps involved in this Arc Flash Analysis, which we are going to discuss here. Step 1: Collect the system’s installation data: The largest effort in an arc-flash hazard study is collecting the data from the site. Start by reviewing the one-line diagrams and electric equipment, site, and layout arrangement with people who are familiar with the site. The diagrams have to be updated to show the current system configuration and orientation before the arc-flash study starts. The one-line diagrams must have all alternate feeds. If SLDs are not ready, prepare them.              Once the diagrams are completed in the basic electric system scheme, enter  the data needed for the short

Kingdom of Saudi Arabia Safety Compliance Requirements for Arc Flash Risk

  Saudi Arabia -Arc Flash Study Standards Requirements The Kingdom of Saudi Arabia with its rich oil and natural gas reserves is considered as the "energy super power". It thus stands as the largest economy in the Middle East. Saudi Arabia is also expanding in industries like construction, industrial gases, cement , metals, fertilizers, electrical power transmission and distribution, plastics,  commercial ship and aircraft  repair. A commercial space or an industry, the main matter of  concern is the provision of  work safe and well maintained working environment. An usual assumption of electrical safety is that electrical accidents are occurred  from electric shock, but many practical cases reveal that rather than the electrical shocks fatality and severe accidents occur more due to an Arc Flash.   Arc Flash Accident                            Arc Flash or simply Electrical Flashover is the release of extensive heat and energy caused by ionization of air around the conductor
