this may be of help to clarify....does the person inside the cage HAVE to wear a harness. People on the working platform 31. It is not appropriate for personnel to stand on the guardrails. In addition, it is advisable not to lean out of the platform when it is raised and, so far as is reasonably practicable, the platform shall be positioned to prevent the need for people to lean out when carrying out their work. If people have to lean out of the platform to carry out work at height then they shall wear harness and lanyards that when linked to the platform’s harness anchorage points prevent them from overbalancing and falling over the rails.
