What is a critical safety instruction for custodial staff using ladders?

• A. Always use a ladder over ten feet tall
• B. Climb no higher than the third step from the top
• C. Never use a ladder alone
• D. Always ensure the ladder is at a steep angle

Answer: (B)

Climbing no higher than the third step from the top of a ladder is critical for safety because it maintains the user’s stability and balance. When someone stands too high on a ladder, they can easily lose their equilibrium, increasing the risk of falls or accidents. The top rungs are typically the least stable position and can lead to an unsafe center of gravity, which is why limiting one’s height on the ladder is a well-accepted safety practice.

While the other options might sound intuitively safe, they either present risky behaviors or are impractical. For example, using a ladder that is over ten feet tall without proper safety precautions is not advisable, as the height increases the danger of falling. Climbing alone can also be risky since having a partner can help ensure stability and offer assistance in case of an emergency. Ensuring the ladder is at an appropriate angle is critical for safety, but it’s only effective if the climber is positioned safely within the limits of the ladder height. Thus, adhering to the guideline of not climbing above the third step from the top is a fundamental and vital safety practice.
