To extend ladder life, you should

• A. Store it in cold places
• B. Use it every day
• C. Keep it free of moisture
• D. Paint it after use

Answer: (C)

Moisture is the main factor that shortens ladder life. When ladders stay wet or sit in damp conditions, metal parts corrode and fasteners weaken, wood can swell, crack, or rot, and fiberglass may suffer from weakened resin/fiber connections over time. Keeping the ladder free of moisture protects these materials, preserving strength, alignment, and the safety of the rungs and feet. Practical ways to do this include storing in a dry, sheltered place, drying the ladder after use, and avoiding damp basements or weather exposure before storing. The other options don’t address the moisture issue: cold storage can still lead to condensation problems, daily use increases wear, and painting after use doesn’t prevent moisture-related damage.
