Make sure that all workers involved in the installation of trench boxes are properly trained and supervised during assembly and installation.

Plan all lifting equipment needed for the excavations ahead of time to ensure that the correct lifting operations can be used.

Don't use trench shields on unstable ground and near structures under increased loadings that require different shoring systems to handle the pressure.

Inspect all components, including lifting points, spacers, clips, and pins.

Access the box only through a ladder.

Never move the box while personnel are inside the excavation.

Do not use any unsupported part of the trench as access.

Upper boxes and extension panels should not be removed until the top of the lower box is above ground level.

To minimize damage, do not lift the box by the struts and do not load it sideways.

Attach the access ladder and guardrails before use.

If in doubt, ask our experts for advice (ESC Trench Shoring Inc.).
