OSHA trench slope calculator and signed trench card

ShoreSafe DC helps the excavation competent person classify soil, solve trench slope width, check trench box ratings, and hold up a clear GO or STOP before the crew enters.

What it answers

• What slope width does this depth and soil class require?
• Is Type C benching blocked before it reaches the crew?
• Does this box rating match the trench depth and soil load?
• Do rain, vibration, surcharge, or water push the call to STOP?
