At about 7:00 a.m. on February 11, 2025, an employee was troubleshooting a system that had failed to start. Suspecting a tripped breaker and intending to test the system's motor leads, he hooked up an insulation resistance tester. The side of the breaker the tester was hooked up to was still energized, resulting in an arc flash. The employee was hospitalized with second-degree burns to his face and right arm.
