Soil classification isn’t a guess — it’s a skill. And only the trained should do it.
Why It Matters:
If the wrong person calls the soil type, the wrong protection may follow. That’s how collapses happen. OSHA requires a Competent Person for a reason — they’re trained to protect lives.
Key Points:
- A Competent Person must be trained in soil mechanics and trench safety.
- They must be authorized to stop work and make safety calls.
- Must be onsite and involved during all trenching operations.
- Responsible for testing, classifying, and re-evaluating soil conditions as needed.
✅ Don’t guess the soil type — get it from the expert.
Ask the Crew:
- Who is our Competent Person today?
- Are they actively testing and checking conditions?
- Do we trust their authority to make the call?
