NIOSH Alert: Request for Assistance in Preventing Injuries and Deaths from Metal-Reinforced Hydraulic Hoses

CDC's National Institute for Occupational Safety and Health (NIOSH) periodically issues alerts on workplace hazards that have caused death, serious injury, or illness to workers. One such alert, Request for Assistance in Preventing Injuries and Deaths from Metal-Reinforced Hydraulic Hoses (1), was recently published and is available to the public. *

This alert warns workers that they may be burned or electrocuted when using metal-reinforced hydraulic hoses on aerial bucket trucks near energized power lines. One fatality occurred when a metal-reinforced hydraulic hose on an aerial bucket truck ruptured and caused a fire after contacting energized power lines. The worker, an electrical lineman, died when he jumped from the burning aerial bucket and fell 35 feet. Subsequent inspection of aerial bucket trucks by the local utility company found that several metal-reinforced hydraulic hoses were installed on booms or aerial buckets that might be used near energized power lines. **

Workers at other utility companies or electrical contracting companies may be exposed to similar hazards associated with metal-reinforced hydraulic hoses. Recommendations to control the hazards associated with hydraulic hoses used on aerial bucket trucks are provided in the alert.
