What sometimes gets overlooked is fall protection. When you grab the lowest rung on the side of your manufacturing plant, warehouse, or office building and look straight up, it could seem like you have a pretty difficult climb ahead of you. Whether that bothers you or not, doesn’t change the fact that at some point you will be 10, 20, or even 30 feet in the air which means you will need some form of fall protection. That’s where ladder cages come in.
The requirement for a cage comes when you have a fixed ladder longer than 20 feet.
