•Wall shear.

•Hazard recognition (con’t)Weather.

Secondary collapse.Vibrations (helicopters, planes,

apparatus etc.)

Trench Rescue

Spoil pile collapse•Being to close to trench

•Min of 2ft from trench

Slough in collapse•Poor water drainage.

•Exposed to natural elements.

•Very dangerous to shore because of overhang.

Trench Rescue

Trench RescueLip in collapse•Heavy Equipment/vibration

•Workers or equipment may fall in

•May be called “Angle of repose”.

Trench RescueShear Wall collapse•Area stresses causing entire section to collapse.

•Cracks parallel to trench.

•Found in trenches that have been exposed for a while.
