Electrical equipment and those who work with it face many dangers. One risk is the arc flash. When electrical current flows through the air between two conductors, this is known as an arc flash. Sometimes, it can happen between one conductor and a grounded surface. The problem is that the energy released from an arc flash can be enormous.
An arc flash is the biggest heat source you’ll ever see. They have been estimated to reach temperatures of more than 35,000 degrees The National Fire Protection Association (NFPA) estimates over 30,000 arc flash incidents happen each year in the U.S. These cause injuries, deaths, and property damage that can reach hundreds of thousands of dollars. This is what makes performing an arc flash analysis a necessity on any jobsite where electrical work takes place.
Understanding Arc Flash and Its Risks

An arc flash happens when electricity jumps through the air between wires or between a wire and a grounded surface. This can create temperatures over 35,000 degrees Fahrenheit and give off a bright light like a small sun. The intense heat can cause nearby metal to explode, creating flying projectiles. The rapid temperature change makes the air expand, resulting in loud pressure waves.

Blinded by the incredible light and almost deafened by the shock, the arc flash victim suffers injuries that can include deep skin burns and eye damage. Hearing loss is common because the arc flash is like a sonic boom.
The Role of IEEE 1584
The IEEE 1584 standard, called “Guide for Performing Arc Flash Hazard Calculations,” is a complete method for figuring out how much energy an arc flash can release. This standard, first published in 2002 and updated in 2018, uses data from many models and tests done in labs to give us accurate measures of the arc flash danger. The 2018 revision, which took almost three years to complete, added new calculation methods and improved old ones.
When groups follow IEEE 1584, they are using established best practices from the industry. This makes the studies they do more accurate and reliable. The standard helps find out how much energy is released during an arc flash event. It also helps set the distances of the arc flash boundary and the selection of PPE needed to protect workers.
The Benefits of Proactive Arc Flash Management
There are many benefits to doing an arc flash analysis. Workplace safety gets better. The chance of accidents that could injure people goes down. Equipment is safer from possible damage caused by arc flashes. This improves the overall trust in how operations run.
Also, there are some pretty good financial benefits. Companies that manage this process well are often more efficient, pay less for insurance, and don’t have as much expensive downtime.
Implementing Arc Flash Analysis into Your Electrical Safety Program
Analyzing the dangers created by arc flashes is very important for electrical safety. It helps find problems safely and measure how bad they may be. Although not all companies are required to do these detailed studies, many places are legally required to follow the National Electrical Safety Code and the National Electrical Code.
Failure to follow these codes can lead to major accidents with lots of injuries and damage. Any company serious about electrical safety should invest in arc flash studies.
