Incident on Jan 14, 2019: Employee's hand is burned in arc flash
At 11:20 a.m. on January 14, 2019, Employee #1, employed by an HVAC company, was troubleshooting an HVAC unit on the roof of a large retail store. Light to heavy rain was forecast. The employee went up to the roof with an umbrella and a volt meter to check the power. The meter showed no power. He also checked for continuity between all lines and found there was no power. He then checked the unit's disconnect switch and turned it to the OFF position. Employee#1 went back downstairs to reset the breaker, and then returned to the rooftop unit. When he turned the disconnect switch back to the ON position, an arc flash occurred. Employee#1's left hand was burned. The employee was transported to the hospital, where he received treatment for second degree burns to his hand. He was released without hospitalization.
