Competent Persons on Excavation

The trenching hazards are known to everybody in the field of excavation.
Nevertheless we do still find many trenches with no cave-in protection although
the means to correct the problem is so easy. Unfortunately, sometimes people
are willing to take chances. But: there really aren't any excuses for not
providing cave-in protection.

An excavation checklist may help the competent person who will make daily
inspections of excavations, the adjacent areas and protective systems for
evidence of a situation that could result in possible cave-ins as well as
indications of failure of protective systems, hazardous atmospheres or other
hazardous conditions.

The designated competent person should have and be able to demonstrate the
following:

1. Training, experience and knowledge of:

- Soil analysis.

- Use of protective systems.

2. Ability to detect:

- Conditions that could result in cave-ins.

- Failures in protective systems.

- Hazardous atmospheres.

- Other hazards including those associated with confined spaces.

3. Authority to take prompt corrective measures to eliminate existing and
predictable hazards and to stop work when required.
