Arc Flash Safety Training
An arc flash sends current through the air, releasing intense heat and light that can cause severe burns or death. In 2 hours online you learn what causes one, how to control the hazard, and how to choose arc-rated PPE and read equipment labels.

-
What is an arc flash?
Electricity and its hazards, what arcing events are, the factors that make an arc flash more severe, and two types of overcurrent protection devices.
-
Regulatory overview
OSHA requirements for shock, electrocution, arc flash and arc blast; how OSHA and NFPA 70E fit together; electrical safety programs; the "electrically safe work condition."
-
Controlling arc flash hazards
Safety principles for working with conductors and equipment: insulation, guarding, grounding and ground fault circuit interrupters (GFCIs).
-
Arc flash PPE & labels
What arc-rating means, choosing arc-rated clothing and PPE, CAT ratings for test instruments, and labeling requirements for electrical equipment.
Safety information: OSHA vs. NFPA 70E
OSHA is the law. Its electrical standards (29 CFR 1910 Subpart S and 29 CFR 1926 Subpart K) say what must be achieved. NFPA 70E is the consensus standard that explains how: hazard assessments, protection boundaries, arc-rated PPE and equipment labeling. OSHA looks to NFPA 70E to show how its requirements can be met, and this course follows the 2027 edition.
Questions
What is an arc flash?
An arc flash happens when electric current leaves its intended path and travels through the air from one conductor to another, or to ground. It releases intense heat and light that can cause serious burns or death.
What is the relationship between OSHA and NFPA 70E?
OSHA is the law. Its electrical standards are performance-based, and OSHA looks to NFPA 70E, a consensus standard for electrical safety-related work practices, for the prescriptive practices that show how to meet those requirements.
Which regulations does this arc flash course cover?
OSHA 29 CFR 1910 Subpart S (general industry), 29 CFR 1926 Subpart K (construction) and the 2027 edition of NFPA 70E.
What is an arc flash study?
An arc flash study is an engineering analysis of a facility's electrical system. It calculates incident energy, sets protection boundaries, and identifies the PPE and labels needed for work on or near energized equipment.
How long is the arc flash certificate valid?
36 months. You can download your PDF certificate immediately after passing the final exam, and renew by retaking the course every 3 years.
Are there any prerequisites?
No. There are no prerequisites for the OSHA Arc Flash Safety Training (NFPA 70E 2027) course.
