Abstract
A ladder safety mechanism comprises at least one clamp, preferably a pair of spaced apart clamps, attachable part way along a ladder, to secure the ladder to part of a structure. In some embodiments, the mechanism includes at least one manually operated actuator, such as a rope or cable, coupled to the at least one clamp to enable a user located at the bottom of the ladder to open the at least one clamp to receive the part of a structure. In some embodiments, the at least one clamp is automatically secured to the part of the structure by placing the clamp onto the structure. The at least one manually operated actuator also enables a user located at the bottom of the ladder to open the at least one clamp to release the part of the structure. The at least one clamp is oriented substantially perpendicularly to a part of the structure to which the ladder is to be attached.
