Do First Aid Kit Items Expire?
Yes. Many first aid kit items have expiry dates, and using expired items can be ineffective or even harmful. Antiseptics lose potency, sterile packaging degrades, and adhesives dry out over time.
Australian WHS regulations require employers to maintain first aid kits in a "ready for use" condition, which means expired items must be replaced promptly.

How to Track Expiry Dates
Manually tracking expiry dates across multiple first aid kits is error-prone. Common approaches include:
- Spreadsheet — log each item's expiry date and set calendar reminders.
- Sticky labels — write the earliest expiry date on the outside of the kit.
- FirstAidLog app — automatically tracks every item's expiry date, sends alerts when items are expiring soon, and flags expired items during inspections. Try it free →
What Happens If You Use Expired Items?
- Antiseptics — may not effectively kill bacteria, leading to wound infection
- Sterile dressings — compromised sterility can introduce bacteria to wounds
- Adhesive bandages — won't stick, defeating their purpose
- Cold packs — may not activate or provide adequate cooling
- Medications — reduced potency and potential for harmful degradation byproducts
From a compliance perspective, using expired items means your kit is not in a "ready for use" state as required under WHS regulations.
Best Practices for Expiry Management
- First In, First Out (FIFO) — when restocking, place new items behind existing ones
- Quarterly checks — inspect all kits every 90 days (all states recommend this)
- 30-day warning window — flag items expiring within the next 30 days for proactive replacement
- Bulk ordering — order replacement items in advance so they're ready when needed
- Temperature storage — store kits away from direct sunlight and extreme heat to maximise shelf life
