First aid symbols in Australian workplaces
First aid is a critical aspect of workplace safety, and being able to quickly identify first aid equipment and facilities can make all the difference in an emergency.
In Australia, like many other countries, the use of standardised symbols and colours for first aid signage ensures consistency and instant recognition, even in high-pressure situations.
These universal symbols ensure reliability, clarity and compliance when using, storing and replenishing first aid products.
In the event of a workplace incident, immediate and clear identification of first aid resources is vital.
Standardised symbols help reduce response times and prevent confusion, especially in diverse workforces where language barriers might exist.
Australian workplace health and safety (WHS) regulations adopt internationally recognised symbols and signage standards to maintain consistency across industries, sites, and states.
Why green and white are used for first aid signs
The colours green and white are not arbitrary choices.
They are grounded in both safety standards and colour psychology. AS 1319 specifies that first aid signs must feature a white symbol on a green background, and this matches the ISO 7010 standard (symbol E003).
Green is universally associated with safety, health, and permission. It is considered a reassuring, calming colour that reduces anxiety, which is essential in medical emergencies.
White symbolises cleanliness, sterility, and clarity. It provides strong contrast against green, making the symbol highly visible and easy to identify from a distance.
In a psychological context, green’s calming properties can help reduce panic and hesitation during emergencies, while white ensures legibility and recognition under various lighting conditions.
First Aid Symbol
This symbol identifies the presence of first aid resources such as kits, rooms, or stations. It helps workers and visitors quickly locate assistance during an injury or health emergency. Prominent and consistent use of this symbol enhances response times and complies with Australian WHS standards.
Expiry Date
The expiry date indicates the point after which a product may no longer be safe or effective. This feature ensures that only high-quality, functional medical items are used in emergency situations. Regular checks of expiry dates help workplaces maintain compliance and protect worker health.
Keep Away from Moisture
This symbol advises that the product should be stored in a dry, moisture-free environment to maintain integrity. Exposure to moisture can degrade packaging and compromise the effectiveness of medical supplies. Proper storage extends product life and ensures safe usage when needed.
Single Use Only
This symbol shows that the item is designed for one-time use to prevent cross-contamination or infection. It promotes hygiene and safety by ensuring that used materials are disposed of promptly after application. Using single-use items protects both the responder and the injured person.
Latex Free
This symbol confirms that the product does not contain latex, a common allergen found in medical supplies. It helps prevent allergic reactions, particularly for individuals with latex sensitivity. Choosing latex-free products improves workplace inclusivity and safety for all staff.
Sterile
This symbol indicates that the product has been sterilised using recognised methods such as Ethylene Oxide (EO), Gamma Radiation (R), or Autoclaving (A). It ensures the item is free from harmful microorganisms when the packaging is intact and within date. Sterile items are essential in preventing infection during treatment or wound care.
Automated External Defibrillator (AED)
This symbol identifies the location of an AED, a critical device for treating sudden cardiac arrest. AEDs analyse heart rhythms and deliver electric shocks to restore a normal heartbeat. Clear AED signage improves survival rates by helping responders locate and use the device quickly in an emergency.
Date of Manufacture
The date of manufacture is used to calculate the safe usage period for medical products. It helps ensure compliance with shelf-life guidelines for both active ingredients and non-sterile consumables. Tracking manufacture dates supports inventory rotation and minimises waste.
Keep Away from Light
This symbol advises that the product should be stored away from light, especially direct sunlight or UV exposure. Light-sensitive materials may degrade or lose potency when exposed. Proper storage maintains product effectiveness and extends its usable life.
LOT Number
The LOT number identifies a batch of products made under the same conditions and at the same time. It is used for traceability, recalls, or quality assurance in case of product defects. Recording LOT numbers helps workplaces maintain accountability and safety compliance.
Do Not Use if Packaging is Damaged
This warning ensures that items are only used when packaging is sealed and undamaged, preserving sterility and safety. Damaged packaging may expose contents to contaminants or compromise their effectiveness. Inspecting packaging before use reduces risk and reinforces safe first aid practices.
Bio Hazard
This symbol flags biological substances such as blood or bodily fluids that may pose infection risks. It alerts responders to handle materials with caution and use appropriate personal protective equipment (PPE). Recognising biohazard areas or waste improves hygiene and workplace safety standards.
Conclusion
First aid symbols are more than just visual markers - they’re vital tools for promoting fast, effective emergency responses in Australian workplaces.
Understanding the meaning behind each symbol, the colour psychology that informs their design, and the standards that regulate their use helps create safer environments for everyone.
Consistent first aid signage aligned with Australian and international standards helps businesses meet their legal obligations, support the wellbeing of their staff, and foster a culture of safety that benefits the entire workplace.
