During this toolbox meeting we will discuss the safety of ladders. The ladder is not a work place, but a means to access a work place. Only when there is no safer equipment to use (fixed scaffold, mobile scaffold or a mobile elevating work platform), the ladder may be used as a work place, as a rare exception.
