A solar technician is working on a rooftop PV system and needs to access modules that are several feet beyond their reach from a securely positioned extension ladder. To avoid overreaching, what is the safest and most compliant action the technician should take?
- ACarefully slide along the top rung of the ladder while maintaining three points of contact.
- BHave a coworker hold the base of the ladder while they lean further.
- CExtend their reach by leaning out from the ladder as far as possible.
- DUse a taller ladder or reposition the current ladder closer to the work area.
Show answer & explanationAnswer & explanation
Correct answer: D. Use a taller ladder or reposition the current ladder closer to the work area.
Overreaching from a ladder is a common cause of falls. The safest and most compliant practice is to ensure the ladder is positioned correctly for the task at hand. If the current ladder is insufficient, a taller one should be used, or the existing one repositioned.
Why the other options are wrong
- A. Sliding along the top rung is unstable and increases the risk of a fall.
- B. Having a coworker hold the ladder does not negate the danger of leaning out and overreaching; it's still an unsafe practice.
- C. Leaning out from a ladder significantly shifts the center of gravity and increases the risk of tipping the ladder.
Ladder Overreaching Prevention
To prevent falls, users should never overreach from a ladder. The ladder must be positioned so the worker can comfortably reach the work area without extending beyond the side rails or leaning excessively.
- Maintain your center of gravity between the side rails.
- Reposition the ladder as needed to reach the work.
- Do not lean out or extend arms/tools excessively.
- Overreaching is a major cause of ladder-related injuries.
Memory trick: Ladder's reach has a golden rule: reposition or get a taller tool.
