By Black Belt Safety Editorial Team Official text as of octubre 15, 2026 Data updated octubre 20, 2026 4 min read

In plain words:

Employers must make sure portable ladders have slip-resistant metal rungs, stepladder spreaders that lock open, and loads within the maximum intended load. Ladders must be used on stable, level surfaces, never moved with someone on them, and secured or barricaded in doorways and walkways. The top step or cap of a stepladder cannot be used, and ladders used to reach an upper level must extend 3 feet above it.
