How to use itA competent person inspects the excavation before each shift and after rain or other events, and removes workers if a hazard is found.

Who it is for and when to use it
Trench collapses can kill in seconds. Under OSHA rules, trenches 5 feet or deeper generally need a protective system unless in stable rock, and a competent person must inspect excavations daily.
Use this as a daily field check with your safety program and the current standard.

The excavation safety checklist in practice
After overnight rain, the competent person finds water in a 6-foot trench and fresh cracking near the edge. Work stops; water is pumped, the shield is repositioned and the crew re-enters after a new inspection.
Why an excavation and trench safety checklist matters
OSHA’s excavation standard requires protective systems for trenches 5 feet deep or more unless they are in stable rock, along with safe access and inspection by a competent person before each shift. A completed checklist shows soil, protection and access were checked before anyone climbed in, which is the main defense against a cave-in.

Sample for Keystone Underground in Allentown, Pennsylvania. Type C soil is why the crew uses a box rather than sloping alone, and the ladder line restates the 25-foot travel rule so it gets checked each morning.
What goes wrong with an excavation and trench safety checklist
Calling 811 too late. Make the request a few working days before digging, as your state requires, and wait for all marks.
Parking excavators or dump trucks near the trench edge. Their weight adds pressure on the wall, so keep traffic back.
Climbing out of the trench on the shoring or shield. Provide proper ladders and keep them within reach in deep trenches.
Other versions of the excavation and trench safety checklist
Plumbing and utility crewsCarry a trench box sized for the deepest work you do so crews are not tempted to skip protection on short jobs.
Landscaping contractorsTreat deep irrigation trenches and tree pits the same way, since soil collapses no matter the trade.
Quick winMark the spoil setback line with spray paint before digging. It makes the rule easy to see and enforce once the pile starts growing.
Excavation and trench safety checklist questions, answered
When is protection required?
Generally at 5 feet or deeper unless in stable rock; check the standard.
Who inspects?
A competent person.
Where should spoils go?
Set back from the edge as required.
Do shallow trenches need checks?
Yes, if there is a cave-in risk.
When does a trench need a protective system designed by an engineer?
OSHA requires protective systems for excavations deeper than 20 feet to be designed by a registered professional engineer. Shallower trenches can use sloping, shoring or shields chosen from the standard’s tables or the manufacturer’s data.
What soil type should I assume if nobody has classified the soil?
Treat it as Type C, the least stable class, which calls for the flattest slopes or full protection. Classifying the soil takes a visual and a manual test by the competent person, and the result should be written on the checklist.
