Accurate evacuation diagrams are a cornerstone of any emergency management plan. In WA, both AS 3745‑2010 and the Work Health and Safety (General) Regulations 2022 impose specific requirements on how diagrams must be designed, displayed and maintained. Below are the most common questions we receive, straight to the point, so you know exactly what to do.
1. What is an evacuation diagram?
An evacuation diagram, often called a “You Are Here” map, shows all exit routes, fire fighting equipment locations (extinguishers, hose reels), assembly areas and hazards. It’s a visual aid designed to guide staff and visitors quickly to safety during an emergency.
2. Who must have evacuation diagrams in WA?
All PCBUs (businesses or undertakings) controlling a workplace in WA, from offices to factories to schools, must display up‑to‑date evacuation diagrams under OSH Regulations 1996 (Reg 3.10) and WHS Regulations 2022 (Reg 43). If people come onto your site, you need diagrams.
3. How often must diagrams be reviewed?
AS 3745‑2010 recommends a desktop audit at least every five years, plus immediate updates after any layout change (new walls, equipment or exit relocations). Your emergency plan should record both the five year interval and trigger events for out of cycle reviews.
4. Do I need both desktop and on‑site audits?
A desktop audit checks your current diagrams against latest standards and building plans. An on site audit verifies exits, equipment and assembly‑areas in person. Combining both ensures full compliance especially after renovations.

5. Are evacuation drills mandatory?
Yes. WA law requires practising evacuation procedures at “reasonable intervals.” While no fixed timetable exists, AS 3745‑2010 suggests at least one full live drill annually, with table‑top exercises (scenario workshops) quarterly. Document drill dates and outcomes in your emergency plan.
6. Can I display digital diagrams instead of prints?
Digital PDFs on intranets and email are acceptable for staff distribution, but printed diagrams (A2/A3/A4) must be clearly displayed at eye level near exits and in common areas. Laminated or framed prints withstand wear and ensure visibility if power or network fails.
7. What size and placement rules apply?
Diagrams should be large enough to read from 1–2 metres away (typically A2 or A3). Place them at each main exit, stairwell landings and at reception or lunchrooms. AS 3745‑2010 specifies placement height (1.4–1.6 metres above floor) for optimal visibility.
8. What happens if I don’t comply?
Non‑compliance can lead to improvement notices or fines from WorkSafe WA, and increased liability in the event of an incident. Outdated or missing diagrams also slow evacuation, raising risk of injury or worse. Regular audits protect both people and your business.
