When PCBU helps
Use PCBU when reading Australian WHS guidance about who must provide safe systems, first aid equipment, trained first aiders, information and emergency arrangements.
Safety boundary: Documentation and policy do not replace immediate first aid, urgent medical advice or emergency response. If a real incident is unfolding, act on the person’s condition, call Triple Zero (000) when it is an emergency and follow the operator’s instructions.
Where it sits: PCBU is commonly read alongside BBV, WHS, IPC, NSI, but each term has a different job. The comparisons later on this page explain those boundaries.

What Does PCBU Stand For?
| P | Person A legal person, which can include a company or organisation. |

Common Mistakes
- Do not assume PCBU always means one individual manager.
- Do not assume buying a kit alone satisfies workplace first aid needs.
- Do not forget consultation, access, training, maintenance and review.
A Real-World PCBU Scenario
The scene: A site manager is deciding who must organise first aid facilities across several work locations.
In this PCBU scene, begin with P for Person: A legal person, which can include a company or organisation. That opening prompt matters here because Use PCBU when reading Australian WHS guidance about who must provide safe systems, first aid equipment, trained first aiders, information and emergency arrangements. Keep the observation tied to Australian workplace first aid obligations and who must make sure first aid is available; in practice, watch the hazard, who was exposed, broken skin or mucous-membrane contact, controls already used and continuing risk rather than reciting the letters without checking the person or setting.
For PCBU, U closes the pattern as Undertaking. Non-commercial organisations and other work arrangements can also be included. Before the sequence is treated as complete, relate it to the exact exposure, time, first aid, PPE used, people affected and who is arranging medical or workplace follow-up. A specific trap to avoid is: Do not forget consultation, access, training, maintenance and review.
Where the scenario could change: Do not assume PCBU always means one individual manager. Documentation and policy do not replace immediate first aid, urgent medical advice or emergency response. If the facts no longer fit a stable PCBU example, stop rehearsing the acronym and move to the safer emergency, clinical or workplace pathway.

PCBU and similar terms
A person conducting a business or undertaking, a term used in work health and safety law. It identifies a duty holder, not a first-aid technique.
Here is how the related terms differ:
- BBV: Viruses that can be carried in blood. The term explains an exposure risk; it does not mean every blood contact causes an infection.
- WHS: Work health and safety: the wider work of managing workplace risks. First-aid planning is one part of it.
- IPC: The everyday steps that help stop infections spreading, such as cleaning hands and using protective equipment.
- NSI: An injury from a needle or another sharp object. The term describes what happened, rather than a set of treatment steps.
