What is the proper technique for securing a ground ladder on sloped or uneven ground?

• A. Use a stable base with feet flat, have a partner foot the ladder, and chock as needed; ensure proper angle (~75 degrees)
• B. Stand ladder on its side
• C. Use only one person
• D. Place ladder feet up the slope

Answer: (A)

Stability and a safe climbing angle are essential when a ground ladder rests on sloped or uneven ground. Start with a stable base: the ladder feet should sit flat on the surface. On uneven ground, use levelers, base plates, or chocks under the feet to create solid, level contact so the ladder won’t rock or shift. Have a partner foot the ladder at the base to apply downward pressure and help control movement as you or a climber ascend. Chock as needed to prevent sideways movement or sliding, especially if one side of the ground is lower than the other. Aim for a proper angle of about 75 degrees, which corresponds to roughly one foot of base distance for every four feet of ladder height; on sloped ground, adjust with the chocks or base supports to maintain that angle so the ladder remains stable and reduces tipping risk. Placing ladder feet up the slope, standing the ladder on its side, or attempting to do the job with only one person all compromise stability and safety.
