A fourth-year HVAC apprentice employed by U.S. Engineering Services suffered fatal electrocution after coming in contact with energized parts while repairing equipment Aug. 24 last year at University Academy, a college prep charter school in Kansas City, Missouri.
An Occupational Safety and Health Administration (OSHA) investigation found the company failed to follow required procedures which would have prevented the incident. A similar incident occurred in July 2021, when another HVAC technician was fatally electrocuted while working on a rooftop air conditioning unit not drained of all its energy in Wichita, Kansas.
OSHA also found the Kansas City-based company failed to conduct hazard assessments to identify personal protective equipment needs and other requirements for field employees at contracted sites and allowed a damaged extension cord to be used at the repair site.
“This worker’s death was avoidable. Employers must follow well-known electrical safety procedures set forth in federal regulations and industry-recognized practices,” said OSHA Area Director Karena Lorek in Kansas City, Missouri. “Companies whose employees work with electricity must take all necessary steps to make sure they are protected from dangerous electrical hazards so they can return home safely.”
OSHA’s investigation found the worker was cleaning a chiller unit in the academy’s mechanical room when the electrocution happened. While the chiller’s fan motor was turned off using the building’s HVAC management system, neither a lock and/or tagout was placed on the unit control switch to ensure electrical power was drained from the coils and the air handler.
Investigators also determined neither arc flash personal protective equipment or lockout/tagout equipment was onsite at time of the incident.
OSHA cited U.S. Engineering Services for three serious and two repeat violations and proposed $197,642 in penalties. The agency identified similar violations after the July 2021 fatality. The company settled the case and paid the penalties assessed by OSHA.
U.S. Engineering Services is one of five companies held by U.S. Engineering in Kansas City. Its holdings include U.S. Engineering Construction, U.S. Engineering Metalworks, U.S. Engineering Innovations and USE Real Estate Holdings.
