A utility trench is 4 ft deep. How close must a ladder or other safe egress generally be?

Correct Answer

B) 25 ft or less

OSHA requires safe egress within 25 ft of lateral travel in trench excavations 4 ft or deeper.

Answer Options
A
Apply 10 ft to the trench ladder spacing condition
B
25 ft or less
C
Apply 50 ft to the trench ladder spacing condition
D
Apply 100 ft to the trench ladder spacing condition

Why This Is the Correct Answer

OSHA requires safe egress within 25 ft of lateral travel in trench excavations 4 ft or deeper.

Why the Other Options Are Wrong

Option A: Apply 10 ft to the trench ladder spacing condition

Choice A (10 ft) is rejected because 10 ft is not the OSHA trench-egress travel distance or access trigger cited here.

Option C: Apply 50 ft to the trench ladder spacing condition

The trap in C is 50 ft. That selection is wrong because 50 ft is not the OSHA trench-egress travel distance or access trigger cited here.

Option D: Apply 100 ft to the trench ladder spacing condition

Choice D gives 100 ft. Its specific error: 100 ft is not the OSHA trench-egress travel distance or access trigger cited here.

Memory Technique

Use a redline memory cue for trench ladder spacing: the stem's condition unlocks 25 ft or less.

Reference Hint

Open 29 CFR Part 1926 (OSHA Construction Standards), 1926-2023 / PSI OSHA Excerpts 2025; use 29 CFR 1926 Subpart P - §1926.651(c)(2); ladders by §1926.1053 to confirm that OSHA requires safe egress within 25 ft of lateral travel in trench excavations 4 ft or deeper.
