Accident: 201080405 - Electric Shock - Direct Contact With Energized Conductor

An electrician was installing a Prescolite EFP5 emergency lighting ballast in an automobile tool room in a vocational education building at a prison. He had pulled the ungrounded circuit conductor from a T-type conduit body located 4.4 meters above the floor. He was standing on the seventh step of a 3-meter-tall fiberglass and aluminum ladder. To gain access to the conductor, which was to be connected to the ballast, the employee had climbed between a lighting fixture that was 3 meters above the floor and a 102-millimeter-diameter metal pipe that was 3.7 meters above the floor. He was also working around a metal sprinkler pipe. The employee, who was not wearing rubber insulating gloves, contacted the 277-volt conductor, received an electric shock, and fell to the floor. He was electrocuted.

Accident: 170831150 - Electric Shock & Fall - Direct Contact With Live Conductor

A 55-year-old electrician was installing a ballast on a 120-volt outdoor motel sign. He contacted an energized conductor on the output side of the ballast while he was standing about 2.4 meters above the ground on an aluminum extension ladder. He received an electric shock, which caused him to fall from the ladder. He sustained head injuries from the fall. The employee was pronounced dead on arrival at a local hospital as a result of electrocution complicated by severe head trauma. The employee had had a history of heart problems.

Accident: 575027 - Electric Shock - Ground Fault In Elevator

An elevator mechanic was working on electrical boxes on the top of a Dover hydraulic passenger elevator. The elevator was not grounded. An insulation breakdown or failure in the ballast of the elevator's florescent lighting fixture energized the entire elevator car. (The ballast was in metal-to-metal contact with the ceiling of the car.) The mechanic was electrocuted.

Accident: 898072 - Electric Shock - Direct Contact With Energized Parts

Two employees of a university were changing light bulbs in the ceiling over a swimming pool area. After determining that a ballast was faulty, one of the employees, who was an electrician, began to replace it. He did not deenergize the circuit before working on the ballast. The electrician, who was sitting on a steel beam, contacted an energized part and was electrocuted.

Accident: 170382220 - Electric Shock - Direct Contact With Energized Parts

A maintenance worker was replacing the ballast in a 277-volt, chain-hung fluorescent lighting fixture in the security office of a shopping mall. He was working from a 2.4-meter-tall ladder. He had not deenergized the lighting circuit, and he received an electric shock as he disconnected the wiring in the fixture. The shock caused the employee to fall from the ladder. He landed on his left ankle and broke it. He was hospitalized for his injuries.

Accident: 170630537 - Electric Shock - Direct Contact With Energized Conductor

A lighting service technician was working with a partner, changing fluorescent lamps and ballasts in the lobby of a bank. Because the work was performed while the bank was open for business, the lights were on, and the 277-volt lighting circuit was energized. The technician was standing on a 2.4-meter fiberglass stepladder, and his body was extended up between the aluminum members of a translucent drop ceiling that hung below the lighting fixtures. He had just replaced a ballast and was connecting the conductors. He apparently touched the energized conductor while he was in contact with another conductor or with the aluminum grid. When he yelled for help, his partner pulled the conductor from his hand, and the injured employee fell from the ladder to the floor. He was electrocuted. Paramedics reported finding current entry and exit wounds on both his hands.
