Safety systems should be provided by anyone responsible for people working at heights on a roof or other area where a risk of a fall exists. This could be a building owner, or facility manager, that requires workers to access the roof for the maintenance of plant an other equipment (e.g. air-conditioning units) or to perform gutter cleaning. Under the Work Health and Safety Regulations 2011 (C’wth), the “…risks to health and safety associated with a fall by a person from one level to another that is reasonably likely to cause injury the person or any other person” are required to be properly managed and mitigated by the person conducting a business or undertaking (PCBU) at a workplace.
