Electric Arc Injuries at Work — Injury Statistics and Claims Information
Electric Arc Injuries at Work
Severe electrical arc incidents remain a persistent threat
OSHA recorded 129 severe cases of electric arc exposure in recent reporting, highlighting a critical risk for workers across multiple sectors. The vast majority of these incidents, specifically 93 percent, result in the direct effects of electric current on the human body.
These injuries are particularly dangerous because they often involve high-voltage contact with electric parts. Workers frequently suffer severe damage to their hands, fingers, and facial regions, which can lead to life-altering consequences and long-term physical impairment.
What's Driving the Trend?
The data shows a clear concentration of risk around electric parts, which were the primary source in 89.9 percent of all reported incidents. These events often occur during routine maintenance or troubleshooting, where failures in de-energizing systems or inadequate protective measures lead to sudden, violent electrical discharges.
Construction, manufacturing, and utilities account for the highest volume of cases, representing 48.8 percent, 17.8 percent, and 17.8 percent of incidents respectively. These industries rely on complex electrical infrastructure, and when safety protocols fail, the resulting arc flash creates an immediate and severe hazard for employees.
Injury Types from Electric Arc Injuries
Top causes based on OSHA incident reports
Electric arc injuries typically occur when a worker interacts with energized equipment, such as utility poles, transformers, or industrial circuit panels. These incidents often happen during tasks like checking voltage, replacing fuses, or moving equipment near live lines, where an unexpected arc flash bridges the gap between a power source and the worker.
| Injury Type | Incidents | |
|---|---|---|
| 1 | Effects of electric current | 120 |
| 2 | Thermal burns | 4 |
| 3 | Surface and flesh wounds and other injuries | 2 |
| 4 | Soft tissue injuries and other injuries | 1 |
| 5 | Amputations, avulsions, enucleations | 1 |
| 6 | Traumatic injuries or exposures— unspecified | 1 |
Why This Matters for Your Case
Employers are legally required to maintain safe electrical work environments under 29 CFR 1910.333, which mandates that live parts must be de-energized before work begins. Failure to provide adequate personal protective equipment, such as flame-resistant clothing and insulated tools, or failing to implement proper lockout-tagout procedures, constitutes a direct violation of OSHA safety standards.
Industries with Most Electric Arc Injuries
Where these injuries occur most frequently
Construction workers face the highest risk, accounting for 48.8 percent of all reported arc flash incidents. The nature of construction work often involves proximity to high-voltage utility lines and temporary electrical setups that may not be fully shielded, creating environments where even a minor error can trigger a catastrophic electrical discharge.
High-Risk Industries and Your Rights
In high-risk sectors like construction and utilities, employers must strictly adhere to 29 CFR 1926.403 for electrical installation safety and 29 CFR 1910.132 for personal protective equipment. These regulations require employers to conduct thorough hazard assessments and ensure that all employees working near energized parts are protected by verified safety barriers and appropriate gear.
Real Incident Reports
From actual OSHA investigation files
The reported incidents reveal a recurring pattern of workers suffering severe burns to their hands, arms, and faces while performing routine electrical tasks. These narratives frequently describe situations where workers believed systems were de-energized or were working in close proximity to energized lines, only to be caught in an unexpected arc flash that bypassed their protective equipment.
"A three-person crew was inter-setting a new utility pole. An employee was working to cut the conductor when a 14.4-kV arc flash occurred. The employee sustained burns to the upper-right torso. The employee was wearing personal protective equipment (PPE), including flame-resistant clothing, rubber gloves, and sleeves."
"The injured employee was standing in the man basket of an aerial lift as another employee drove the lift across the yard to their destination. The two employees were going to torque nuts that were installed on the 4-hole pads of elevated substation equipment (including various types of transformers, lightning arresters, etc.). At their destination, they were ascending in the man basket when electricity arced to the basket. The injured employee sustained arc flash burns to their face and right arm."
"An employee was working on a partially deenergized electrical system. His wire touched an energized wire, resulting in an electrical flash that caused second- and third-degree burns to his neck, forearm, and ear."
"An employee was checking voltage on a meter. There was an arc flash, and the employee suffered burns to both hands."
"An employee was troubleshooting a 3-phase electrical circuit and was replacing a fuse. An arc flash occurred and the employee suffered burns to both hands."
"An employee had been pulling out a fuse. A motor control center (MCC) bucket exploded and produced an arc flash. The employee sustained burns to both arms."
"On June 22, 2025, an employee was performing scheduled maintenance at a ladle metallurgical furnace vault. As the employee was replacing a shear pin, they contacted an energized circuit, resulting in an arc flash. The employee sustained second-degree burns to their buttocks and both legs."
"A crew was installing a pistol (electrical connection) to a new section of underground electric cable. The injured employee went to align the cable and pistol and it contacted a live bushing instead of the grounded bushing. An arc flash occurred. The employee sustained second-degree electrical burns to his left forearm and right hand, index finger, and thumb. The employee was hospitalized."
"At 11:50 a.m. on June 17, 2025, an employee was working on a 60-amp battery. As he was removing nuts with a wrench, there was an arc flash. The wrench welded itself to the terminals, and the employee suffered second-degree burns along the left palm, thumb, and index finger, as well as a burn on his right middle finger."
"An employee was making an electrical connection at a power meter outside a building. There was an arc flash and the employee was shocked, suffering second-degree burns on both hands."
