Short answer

An OSHA trenching and excavation checklist records a competent person's inspection of an excavation: soil type, protective system, access and egress, water, atmosphere, spoil and adjacent loads. 29 CFR 1926.651(k)(1) requires daily inspections by a competent person, and 1926.652 requires a protective system unless the excavation is entirely in stable rock, or under 5 feet with no indication of a cave-in.

Checked against OSHA 29 CFR 1926 (Current eCFR text, up to date as of 2026-10-22 (read 2026-10-26)) on by the MapTrack templates team. How we check templates

Key takeaways

  • The MapTrack OSHA trenching and excavation safety checklist contains 34 checks across 7 sections. Sections covered: Soil Classification, Protective System, Utilities and Services, Access and Egress, Site Conditions, Atmospheric Testing (if required), Authorisation.
  • A competent person inspects excavations, adjacent areas and protective systems daily for cave-in risk, failing protection and hazardous atmospheres (1926.651(k)(1)).
  • Where the competent person finds such evidence, exposed employees are removed from the area until precautions are taken (1926.651(k)(2)).
  • Protective systems are required unless the excavation is entirely in stable rock, or under 5 feet with no cave-in indication (1926.652(a)(1)).
  • Trenches 4 feet or deeper need a stairway, ladder, ramp or other safe egress within 25 feet of lateral travel (1926.651(c)(2)).
  • Choose a protective system design option under 1926.652; classify soil as stable rock or Type A, B or C under Appendix A where that option relies on it.

What is an OSHA trenching and excavation safety checklist?

An OSHA trenching and excavation safety checklist is a structured inspection form used to verify compliance with OSHA 29 CFR 1926 Subpart P (Excavations) before and during trenching and excavation work. MapTrack helps site supervisors and competent persons digitise these inspections so every trench assessment is recorded with date time location soil classification and protective system details linked to the project record.

OSHA Subpart P requires that a competent person inspect excavations and trenches daily before the start of work and as conditions change. Any trench 5 feet (1.5 metres) or deeper requires a protective system unless the excavation is made entirely in stable rock. The three recognised protective system options are sloping and benching shoring and shielding (trench boxes). The competent person must be capable of identifying existing and predictable hazards and have the authority to take prompt corrective measures to eliminate them. Trenching is one of the most hazardous construction activities with cave-ins being the primary cause of fatalities. This checklist provides a consistent framework for the competent person to assess and document trench safety before workers enter.

Benefits of using this OSHA trenching and excavation safety checklist

  • Legal compliance: documented daily inspections meet OSHA 29 CFR 1926.651 and 1926.652 requirements for competent person assessment
  • Cave-in prevention: systematic verification of soil classification and protective systems reduces the risk of trench collapse
  • Utility strike prevention: confirming utility locates are completed and marked before digging prevents contact with underground services
  • Worker access safety: verifying ladder or ramp spacing ensures workers can exit the trench within 25 feet of travel as required by OSHA
  • Atmospheric hazard detection: testing for hazardous atmospheres in deep trenches protects workers from oxygen deficiency or toxic gas exposure
  • Accountability: signed inspection records clearly identify the competent person and the conditions assessed at each inspection

What to include in an OSHA trenching and excavation safety checklist

This OSHA trenching and excavation safety checklist covers 8 key areas:

  • Competent person designation: record the name and qualifications of the competent person conducting the assessment
  • Soil classification: classify the soil as Type A Type B Type C or stable rock using at least one visual and one manual test per OSHA 1926 Appendix A
  • Protective system: document the selected protective system (sloping benching shoring or shielding) and confirm it matches the soil type and trench depth per OSHA 1926 Appendix B C or D
  • Utility locates: confirm all underground utilities have been located and marked before excavation begins per OSHA 1926.651(b)
  • Access and egress: verify ladders stairways or ramps are provided so no worker travels more than 25 feet laterally to reach a means of egress per OSHA 1926.651(c)(2)
  • Spoil pile distance: confirm excavated material and equipment are at least 2 feet from the edge of the trench
  • Water accumulation: assess water conditions and confirm controls such as dewatering or diversion are in place before workers enter
  • Atmospheric testing: for trenches deeper than 4 feet in potentially hazardous conditions test the atmosphere for oxygen content flammable gas and toxic substances

How to use this OSHA trenching and excavation safety checklist

  1. Classify the soil: perform at least one visual test and one manual test (such as a thumb penetration test or pocket penetrometer) to classify the soil as Type A B C or stable rock per OSHA Appendix A
  2. Select and verify protective system: confirm the protective system matches the soil classification and trench depth. For sloping verify the angle matches the maximum allowable slope for the soil type. For shoring and shielding confirm the system is rated for the depth and soil conditions
  3. Check utility locates: verify that all underground utility locates have been completed and marked and that hand digging is used within the tolerance zone around marked utilities
  4. Inspect access and egress: confirm ladders stairways or ramps are positioned so no worker must travel more than 25 feet laterally to reach one. Check that ladders extend at least 3 feet above the trench edge
  5. Inspect spoil pile and surcharge loads: confirm excavated soil and materials are at least 2 feet from the trench edge and that no heavy equipment or surcharge loads are positioned where they could contribute to a cave-in
  6. Test atmosphere: for trenches deeper than 4 feet in areas where hazardous atmospheres could exist test for oxygen concentration flammable gas and carbon monoxide before entry and continuously if conditions may change
  7. Document and authorise: complete the checklist record all findings and sign off before authorising workers to enter the trench. Repeat the inspection if conditions change during the shift

How often should you complete this checklist?

OSHA 29 CFR 1926.651(k)(1) requires the competent person to inspect excavations daily before the start of work and as needed throughout the shift. Inspections must also be conducted after every rainstorm or other hazard-increasing occurrence. If conditions change at any point during the day such as water ingress soil sloughing or vibration from nearby equipment the competent person must re-inspect and take corrective action before work continues.

In practice the competent person should be present on site whenever workers are in or near the trench. The daily inspection is the minimum. Continuous monitoring of conditions is the expectation under OSHA Subpart P.

Frequently asked questions

OSHA 29 CFR 1926.652(a) requires a protective system for all excavations 5 feet (1.5 metres) or deeper unless the excavation is made entirely in stable rock. The three options are sloping and benching (Appendix B), timber shoring (Appendix C), and aluminium hydraulic shoring or trench shields (Appendix D). The competent person selects the system based on soil classification and trench depth.

Soil is classified as Stable Rock, Type A, Type B or Type C using OSHA Appendix A. The competent person must perform at least one visual test and one manual test. Visual tests include evaluating particle size, fissures, layering and water seepage. Manual tests include the thumb penetration test, pocket penetrometer, shearvane or torvane. Type C is the least stable and requires the steepest sloping angle or strongest shoring.

OSHA 1926.651(c)(2) requires that a stairway, ladder, ramp or other safe means of egress be located in trench excavations that are 4 feet or deeper so that no worker must travel more than 25 feet laterally to reach it. Ladders must extend at least 3 feet above the top of the trench.

A competent person under OSHA is someone who can identify existing and predictable hazards in the surroundings or working conditions and who has the authority to take prompt corrective measures to eliminate them. For trenching, this person must be trained in soil classification, protective system selection, and excavation hazard recognition.
