OSHA 10-Hour Construction ReviewStairways and LaddersHard
A worker is carrying materials up a portable ladder. According to OSHA, what is the safest practice for carrying objects while ascending or descending a ladder?
- ACarry objects that do not obstruct vision and allow for free use of both hands for climbing.
- BCarry objects in one hand while maintaining three-point contact with the other hand and two feet.
- CUse a hoist or a separate person to pass materials up, keeping hands free for climbing.
- DSecure the object to the worker's back using a backpack or harness, ensuring balance.
Show answer & explanationAnswer & explanation
Correct answer: C. Use a hoist or a separate person to pass materials up, keeping hands free for climbing.
OSHA emphasizes maintaining three points of contact on a ladder. Carrying materials by hand, even if vision is clear, compromises this. The safest practice is to keep both hands free for climbing by using mechanical means (hoist) or having another person pass materials.
Why the other options are wrong
- A. While vision should not be obstructed, the primary concern is having both hands free for climbing, which this option does not guarantee.
- B. This method compromises three-point contact, increasing fall risk.
- D. While it keeps hands free, attaching objects to the worker's back can shift their center of gravity, affecting balance and increasing the risk of a fall, especially on a ladder.
Ladder Materials Handling
When using a ladder, materials should be handled in a way that allows the climber to maintain three points of contact and keep both hands free.
- Prioritize three-point contact.
- Avoid carrying heavy or bulky items by hand.
- Use hoists, ropes, or another person to move materials.
Memory trick: Hands for climbing, not for hauling!
