During operations, there is a failure of reservoirs, hoses or lines containing fuel, hydraulics, lubrication, coolants etc. caused by:

  • Caused by rubbing, vibration, corrosion etc.
  • Awkward to reach or poorly sited isolation point (can’t disable fuel flow)
  • The released liquid is a fuel that can be ignited in its specified or particular state e.g. turbo charger, exhaust, electrical fault, atomised fluids at pressure etc.
  • Pressurised bearings which continue to feed fuel (oil) to turbo even after shutdown of engine triggered
  • Gravity fed oil to turbo (continues to feed fuel (oil) after shutdown of engine triggered)
  • Failure to consider the damage exposure of external components (e.g. flammable liquid storage tank caps and breathers, overflow position, etc.)
  • The loss of containment is due to equipment or component design failure from OEM or third-party supplier.
