The "Do not use ladder" sign warns the individual of the dangers of using a given ladder or step and, by doing so, ensures health and safety measures are met in the workplace. It pictures a barred off image of an individual attempting to use a ladder to clearly convey the message.

The sign is best displayed above, right next to or directly on a ladder that should not be used. It can be placed in both public and private spaces, but best for workplaces with hands on employee work and involvement.
