A trench ladder must be within 25 feet of workers. A 95-foot straight trench is laid out with access at both ends and intermediate points. What minimum number of access points is needed?
Correct Answer
A) 5 points.
Ninety-five feet divided by 25 feet is 3.8 spaces; round up to 4 spaces, which requires 5 access points.
Why This Is the Correct Answer
Ninety-five feet divided by 25 feet is 3.8 spaces; round up to 4 spaces, which requires 5 access points.
Why the Other Options Are Wrong
Option B: 4 points total.
4 points total. is below the supported result for excavation access calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 6 points total.
6 points total. is above the supported result for excavation access calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 7 points total.
7 points total. is above the supported result for excavation access calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Memory Technique
Planning Trench takeoff: count the condition before counting the package.
Reference Hint
Study anchor (closed-book): memorize Excavation access calculation from Cal/OSHA Title 8 Construction Safety Orders; CSLB B General Building. / Cal/OSHA Title 8 excavation access and egress; know the rule or calculation trigger without relying on exam-room lookup.
