Arc flashes are sudden and violent releases of electrical energy that can cause severe burns, blast injuries, and even death. In this Arc Flash course, you’ll learn what arc flashes are, how they differ from electric shock, and how to prevent serious injuries through safe work practices, proper PPE, and electrically safe working conditions.
Arc flashes are sudden and violent releases of electrical energy that can cause severe burns, blast injuries, and even death. This course explains the difference between arc flash and shock, how arc flash injuries occur, and what you can do to avoid them. You’ll learn about safe tool use, the importance of PPE with proper arc ratings, and how to prevent accidents by powering down equipment, locking out controls, and setting up arc flash boundaries.
You’ll also understand how to recognize warning labels, avoid crossing into danger zones, and support electrical safety—even if you're not a qualified worker. By following the correct steps before, during, and after electrical maintenance, you can help create a safer work environment for everyone.
Learning Objectives:
- Identify the differences between arc flash and electric shock
- Recognize conditions that increase the risk of arc flash incidents
- Apply proper procedures for de-energizing and locking out equipment
- Select and use PPE with the correct arc rating for specific tasks
- Describe how to set and enforce arc flash boundaries

Electricity. It's so common in our homes and workplaces that it's easy to take it for granted and to forget about its hazards. But with more than 1,000 people being killed every year in electrical accidents and about 30,000 being injured, electrical safety literally is a matter of life and death. Electricity poses two major hazards to those who work with or around it. The most intense is arc flash, a sudden, violent release of electrical energy. Its powerful heat and blast effects can cause severe injuries and fatalities. The second is shock. When electric current passes through your body, it can cause burns, internal injuries, cardiac arrest, even death. Many people confuse the two and think that arc flash is just a type of shock, but it's not. So let's first look at what the difference is.
