Comprehensive Work Health and Safety Study Notes

Foundations of Workplace Health, Safety, and Duty of Care

• Core WHS Definitions:

  • Health: Defined as complete physical, mental, and social wellbeing, rather than merely the absence of disease or infirmity.
  • Safety: The state of being free from harm, injury, or risk of loss.
  • Hazard: Any source, situation, or object with the potential to cause harm, injury, illness, or damage to property and the environment.
  • Risk: The combined measure of the likelihood that harm will occur and the severity/consequence of that harm.
  • Duty of Care: A legally binding and moral responsibility placed upon individuals and organizations to ensure the safety, health, and wellbeing of themselves and others in the workplace.
  • Work Health and Safety (WHS) Responsibility: WHS is a shared legal responsibility across all levels of an organization, encompassing workers, Persons Conducting a Business or Undertaking (PCBU), and workplace visitors.

• Work Health and Safety Act $2011$ (NSW):

  • Establishes the overarching statutory framework, detailing specific legal duties, obligations, offences, and enforcement protocols.
  • Workers: Broadly defined under the Act to include employees, trainees, contractors, subcontractors, students on work experience, and volunteers.
  • Person Conducting a Business or Undertaking (PCBU): The legal entity or individual operating a business or business enterprise (such as an employer or corporate entity).
  • Statutory Worker Obligations: Must perform work safely at all times, strictly adhere to reasonable health and safety instructions, and proactively report identified hazards.
  • Statutory PCBU Obligations: Must provide adequate training and instruction, supply Personal Protective Equipment (PPE) without cost to workers, continuously monitor workplace hazards and risks, and maintain safe systems of work.
