The hazard
We use ladders so often that it is easy to stop thinking about them. A ladder fall can start with one quick choice: grabbing the wrong ladder, skipping the setup, or reaching too far. Even a short fall can cause a serious injury.
The action
Open a stepladder all the way and lock the spreaders before you climb. Never use the top or the top step as a step. Do not climb the back cross-bracing unless the ladder has steps on both sides, and never lean a closed stepladder against a wall to climb it. (29 CFR 1926.1053(b)(13))

What would make you take a ladder out of service?
Takeaway: Pick the right ladder, check it, set it up right, and keep a hand on it every time you climb.
