What are three ladder stability indicators when operating on the ground?

• A. Slippery footing, unstable base, and no spotter.
• B. Ladders placed on uneven terrain with no guidance.
• C. Only one leg contacting the ground.
• D. Firm footing, secured base, and a lookout or anchor person to assist.

Answer: (D)

When a ladder is on the ground, stability comes from three key indicators: firm footing, secured base, and a lookout or anchor person to assist. Firm footing means the ladder feet grip a solid, level surface so they don’t slide or sink. If the ground is loose, slick, or uneven, address it before climbing so each foot has solid contact. Secured base means the bottom of the ladder is stabilized and cannot shift or wobble—the feet are fully planted, spreaders are locked, and any movement at the base is controlled. A lookout or anchor person provides a steadying presence, helping to hold the ladder in place, guiding its position, and watching for hazards so you don’t lose balance while climbing or working. This combination directly reduces slipping, tipping, and side-to-side movement, making ladder use on the ground safer. Scenarios without these protections—slippery footing, uneven terrain without guidance, or having only one leg contacting the ground—increase the risk of collapse or slip, which is why the three indicators described are the best practice.
