HYDRAULIC LINE FAILURE
Hydraulic line failure during Aerial Device operation presents numerous hazards. Be aware that a hydraulic
oil mist caused by a leak or hydraulic line failure is conductive even though nonconducting oil is used.
WHAT CAN CAUSE A HYDRAULIC LINE TO FAIL?
• Poorly maintained hydraulic system.
• Improperly assembled and installed hydraulic lines.
• Weather checked hose assemblies.
• Hydraulic tool hoses that are allowed to cross phase to phase or phase to ground.
• Boom contact with phases causing a short circuit, which overheats the hydraulic line.
• Improper system pressure setting.
• Overheating the hydraulic system.
• Snagging of hydraulic lines on fixed objects.
A spray or mist produced by a hydraulic leak under pressure is very hazardous to
personnel. This spray or mist can puncture the skin or become embedded beneath the
skin. This condition would require immediate medical attention.
H23877A
Escaping fluid under pressure
can penetrate skin causing
serious injury.
Relieve pressure before disconnecting
hydraulic lines. Keep away from leaks
and pin holes. Use a piece of
cardboard or paper to search for leaks.
Do not use your hand.
Fluid injected into skin must be
surgically removed within a few hours
by a doctor familiar with this type
injury or gangrene will result.
