When working in a trench, what is the maximum horizontal distance that workers are permitted to be from a means of egress (such as a ladder or ramp) according to Cal/OSHA?
- A30 feet
- B25 feet
- C20 feet
- D15 feet
Show answer & explanationAnswer & explanation
Correct answer: B. 25 feet
Cal/OSHA requires that a means of egress, such as a ladder, staircase, or ramp, be located within 25 feet of all workers in a trench that is 4 feet or more in depth. This ensures rapid escape in an emergency.
Why the other options are wrong
- A. This distance exceeds the Cal/OSHA maximum, increasing the risk to workers in an emergency.
- C. This distance is less than the Cal/OSHA requirement, making it safer but not the specified maximum.
- D. This distance is less than the Cal/OSHA requirement, making it safer but not the specified maximum.
Cal/OSHA Trench Egress Distance
A means of egress (ladder, ramp, etc.) must be located within 25 feet (7.62 meters) of workers in trenches 4 feet (1.22 meters) or deeper.
- Applies to trenches 4 feet or deeper
- Means of egress required
- Maximum 25 feet horizontal distance
Memory trick: Twenty-five feet, quick retreat!
