Part 3 of the WHS Act and Regulation 699 require the PCBU to notify its WHS regulator immediately of serious work-related incidents: deaths, serious injuries and illnesses, and dangerous incidents, affecting anyone at the workplace, whether worker, contractor, volunteer or member of the public, so that the systems and issues behind them can be found and fixed. For biological hazards the notifiable incidents are: an injury or illness that needs, or would normally need, medical treatment within 48 hours of exposure to a substance, such as a healthcare worker with no hepatitis B immunity getting a drop of a patient's blood in the eye; an infection to which work contributed significantly, including infections reliably traced to handling microorganisms, treating or caring for a person, contact with human blood or body substances, or handling or contact with animals or animal material; the occupational zoonoses Q fever, anthrax, leptospirosis, brucellosis, Hendra virus, avian influenza and psittacosis caught through work with animals, hides, skins, wool, hair, carcasses or animal waste; and an uncontrolled escape, spill or leak of a substance, laboratory cell cultures for example, that exposes a person to an immediate or imminent serious risk. The incident site is preserved so far as reasonably practicable until an inspector arrives or directs otherwise, which does not stop anyone helping the injured, removing a deceased person, making the site safe by switching off equipment or cordoning it off, or assisting a police investigation. The regulator can advise what is notifiable and how to notify; some conditions carry public health reporting duties too, but once the WHS threshold is met the WHS regulator must be notified whatever other process or authority is involved.
