The Work Health & Safety Act 2011 requires a PCBU (Person Conducting a Business or Undertaking) to provide correct training and documentation to their workers and those who they have control or influence over to ensure their health and safety. This is vital when you have employees or contractors who are working at heights.
Primary Duty of Care, Section 19 (3)
…a person conducting a business or undertaking must ensure, so far as is reasonably practicable;
(f) the provision of any information, training, instruction or supervision that is necessary to protect all persons from risks to their health and safety arising from work carried out as part of the conduct of the business or undertaking”.
