OSHA requires which of the following trenches to have a protective system installed?
Select the best option.
O
A trench 1 foot deep.
A trench 3 feet deep.
A trench 14 feet deep.

Answer 1

These are all wrong. OSHA requires a trench to have a protective system starting at 5 feet.

Step-by-step explanation:

OSHA's own rules state this, unless it is in stable rock. If it is under 5 feet, it isn't required and can be decided by someone qualified.

Answer 2

A trench 14 feet deep would definitely require a protective system, due to the the minimum being 5 feet.
