Do NOT enter an unprotected trench!
|
Each employee in a trench shall be protected from a cave-in by an adequate protective system.
Some of the protective systems for trenches are: |
Sloped for stability; or
|
Cut to create stepped benched grades; or
|
Supported by a system made with posts, beams, shores or planking and hydraulic jacks; or
|
Supported by a trench box to protect workers in a trench.
|
Additionally, excavated or other materials must be at least 2 feet back from the edge of a trench; and
|
A safe means of egress shall be provided within 25 feet of workers in a trench.
