What items must be discarded once a first aid kit expires?
Short Answer: Anything in the kit whose function depends on sterility, adhesion or chemical activity has to come out at its expiry date. That covers sterile dressings, adhesive strips, saline and eyewash, antiseptic wipes, disposable gloves, CPR face shields and instant cold packs. Instruments, unopened non-sterile bandages and the case itself can stay, which is why first aid kits are almost never replaced whole when a date passes.
A first aid kit does not have a single expiry date. It has as many dates as it has dated items, and the kit is only usable to the earliest one that matters. Understanding which items degrade, how quickly, and what happens to them afterwards keeps the process from turning into an annual bin-and-rebuy exercise. Before your next inspection, you also need to consider the following:
• Which supplies typically expire first?
• Can any items be safely retained past expiry?
• How should expired medical supplies be disposed of?
• Is full kit replacement better than partial restocking?
Which supplies typically expire first?
Sterile saline is usually the first item to go. Sealed ampoules and small bottles carry a shelf life measured in a couple of years, and once a container is opened it should be discarded after use rather than returned to the kit. Eyewash held in larger bottles has the same problem in a more expensive form, which is why single-use packaging suits most workplaces better than a bulk container.
Adhesive strips and dressings follow. The adhesive itself dries and loses grip long before anything visible changes, and a strip that will not stay on a wet or moving finger is doing nothing useful. Sterile gauze, wound pads and eye pads carry dates tied to the integrity of their sterile barrier rather than the material inside, so a pack that has been crushed or damp-affected is out regardless of what the date says. Antiseptic and alcohol wipes dry out through their sachets over time, often faster than the printed date suggests if the kit lives somewhere warm.
Disposable gloves are the item most often overlooked. Nitrile and latex both degrade with heat and light, and a glove that tears on the way on has failed at the worst moment. Instant cold packs lose their reaction, CPR face shields have valves and film that perish, and emergency blankets fail at the packaging seal. Any kit stored in a vehicle, a shipping container or an unshaded outdoor cabinet will run through all of these faster than the same kit in an air-conditioned office, which is worth building into your inspection interval rather than trusting the dates alone.
Can any items be safely retained past expiry?
Plenty of the kit stays. Stainless steel shears, tweezers and splinter probes have no expiry at all and only need to be clean and functional. The same applies to a resuscitation record card, a notebook and pencil, and the kit register itself. Unopened non-sterile items such as crepe and conforming bandages, triangular bandages and safety pins generally carry no date either, though they should be discarded if the packaging has been opened, stained or crushed.
The test worth applying is simple. If the item works because it is sterile, because it sticks, or because a chemical inside it is still active, the date governs and the item goes. If it works because of its physical shape and it is undamaged, the date is irrelevant. A pair of shears does not become less sharp because a sticker says 2023.
The case deserves its own check at the same time. AS 2675-1983 covers the container and its ability to keep dust and moisture away from the contents, so cracked latches, perished seals or a faded compliance marking are reasons to replace the case even when the contents are current. Kits carried in utes and toolboxes tend to fail here first.
How should expired medical supplies be disposed of?
Unused and uncontaminated items are not clinical waste. Expired dressings, unopened gauze and out-of-date gloves can go into general waste in most jurisdictions, and the sensible step is to open or mark the packaging first so nothing is retrieved and used later. Donating expired sterile items is not an option, because the sterility claim is exactly what has lapsed.
Anything contaminated with blood or body fluid follows a different route entirely. Used dressings, gloves and wipes from a treatment go into the clinical waste stream under your state or territory EPA requirements, not into the general bin, and a workplace with any likelihood of that occurring should have the arrangement in place before it is needed. Sharps go to a compliant sharps container regardless of quantity.
Medications are the exception most workplaces get wrong. The Safe Work Australia Model Code of Practice: First Aid in the Workplace advises against holding medications such as pain relief in workplace kits, and where they have accumulated anyway they should not go into the bin or down a sink. Take them to any community pharmacy under the Return Unwanted Medicines arrangement, which accepts them without charge. Small volumes of saline can go down a sink, but large quantities of antiseptic solution are worth checking with your local water authority first.
Is full kit replacement better than partial restocking?
Partial restocking is the right answer in most cases. The instruments, the case and the non-dated items make up a real share of what you paid, and throwing them out with a handful of expired sachets is money spent for nothing. Replacing only what has lapsed also keeps the maintenance record continuous, which is what an inspector is reading.
Full replacement earns its cost in narrower circumstances. A case that has failed physically, a site whose risk profile has changed enough that the kit specification no longer matches the assessment, or contents that predate a code revision such as the 2024 Western Australian update are all reasons to start again. So is a kit bought as a complete unit five years ago, where nearly everything dates from the same purchase and expires within months of everything else. Staggering replacement dates from that point on avoids repeating the problem.
Furthermore, a special duty is placed on the PCBU to ensure that all first aid kits are routinely inspected and maintained. Expiry management is where that duty is most often left undone, because it requires someone to open every kit on a schedule and act on what they find. The SURVIVALSWAP managed restocking service from SURVIVAL handles the cycle directly, replacing dated items before they lapse and leaving a documented record of each visit.
Related Question
How often should a workplace first aid kit be checked for expired items?
The Model Code of Practice expects kits to be checked regularly without setting a fixed interval, which leaves the frequency to your risk assessment. A quarterly check suits most workplaces and catches short-dated items with months to spare. Kits in vehicles, outdoor cabinets or high-use areas justify a monthly look, since heat and consumption both move faster there. Every check should also follow any use of the kit, because the item consumed during an incident is the one most likely to be missing when it is next needed. Recording the date and the checker's name each time turns the routine into the evidence the duty actually requires.
Conclusion
Clearing an expired kit is a sorting exercise rather than a disposal exercise. Sterile, adhesive and chemically active items leave, instruments and undamaged non-sterile stock stay, and the case is judged on its condition instead of a date. Doing that properly costs a fraction of a full replacement and leaves a maintenance record behind it. SURVIVAL supplies workplace-compliant kits along with the individual first aid accessories needed to restock them item by item as dates fall due.
