Arc Flash Injury Statistics

Arc flash incidents keep getting costly, with the average workers’ comp claim exceeding $1.2 million per case and medical and lost productivity totaling $1.4 billion annually, yet the biggest drivers are still preventable failures of PPE and labeling rather than uncontrollable physics. Learn how human error, maintenance, and switchgear mishandling shape the highest risk scenarios, and why newer controls can cut incidents by 70 percent while improving protection against even severe voltage and fault conditions.
