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.
Sterile items (plasters, saline, sterile dressings, eye pads) and anything with a chemical or adhesive (antiseptics, cold packs, burn gels) carry a use-by date. Plain non-sterile items such as crepe, triangular and conforming bandages usually don't. The first aid Code of Practice asks that kit items are within their expiry dates and that sterile products are still sealed, so expired items should be replaced at the next check.
Complete Expiry Guide by Item
| Item | Typical Shelf Life | Expires? | Replacement Notes |
|---|---|---|---|
| Antiseptic solution | 2-3 years | ✅ Yes | Check printed date. Discard if cloudy or discoloured. |
| Antiseptic wipes | 2-3 years | ✅ Yes | Dry out over time even if sealed. Check packaging. |

| Non-adherent dressings | 5 years | ✅ Yes | Same as sterile dressings — check packaging seal. |
| Instant cold packs | 2-3 years | ✅ Yes | Chemical compounds degrade. Replace if leaked or punctured. |
| Adhesive plasters (bandaids) | 3-5 years | ✅ Yes | Adhesive degrades — won't stick properly when old. |
| Hydrogel / burns dressings | 2-3 years | ✅ Yes | Gel dries out over time. Check printed expiry date. |
| Resuscitation face mask | 3-5 years | ✅ Yes | One-way valve may degrade. Replace per manufacturer date. |
| Eye pads (sterile) | 5 years | ✅ Yes | Sterility depends on intact packaging. |
| Wound closure strips | 3-5 years | ✅ Yes | Adhesive degrades — won't hold wound edges together. |
| Paracetamol (if included) | 2-3 years | ✅ Yes | Mandatory printed expiry. Must be discarded when expired. |
| Ibuprofen (if included) | 2-3 years | ✅ Yes | Mandatory printed expiry. Must be discarded when expired. |
| Conforming bandages | Usually no date* | ❌ Usually not | Non-sterile ones rarely carry a date. Follow any printed use-by date. Replace if soiled or the elastic has gone. |
| Triangular bandages | Usually no date* | ❌ Usually not | Fabric doesn't expire. Follow any printed use-by date. Replace if soiled, torn or used. |
| Crepe bandages | Usually no date* | ❌ Usually not | Some brands print a use-by date. Elastic weakens over the years: replace if it no longer stretches. |
| Safety pins | Indefinite | ❌ No | Replace if rusted. |
| Scissors | Indefinite | ❌ No | Keep clean and sharp. Replace if rusted or dull. |
| Tweezers | Indefinite | ❌ No | Replace if tips no longer grip or if rusted. |
| Nitrile/latex gloves | 3-5 years | ✅ Yes | Nitrile degrades in heat. Replace if brittle, discoloured, or sticky. |
| Thermal blanket (foil) | Indefinite* | ❌ No | Replace if packaging opened or foil torn. |
| Plastic bags | Indefinite | ❌ No | Should be clean and sealable. |
* "Indefinite" or "usually no date" means most products carry no printed expiry date. Always follow a date if the pack shows one, and replace items that are damaged, soiled or no longer fit for purpose.
How to Read the Date on the Pack
Medical packaging uses standard symbols, so you can read the date whatever language the pack is in:
- Hourglass — the use-by (expiry) date. Replace the item after this date. Sometimes printed as EXP.
- Factory shape — the date the item was made. Sometimes printed as MFG. This is not an expiry date.
- LOT — the batch number, used for recalls.
- STERILE — the item is sterile while the seal is intact and the date hasn't passed.
If a pack shows only a manufacturing date, the maker hasn't set an expiry. Replace the item based on its condition.
Quick Answers: Does It Expire?
Do crepe bandages expire?
Most crepe bandages are not sterile, so many have no use-by date. Some brands still print one, so check the pack for an hourglass symbol or "EXP". Even without a date, replace a crepe bandage once it loses its stretch, gets dirty or its wrapper is damaged.
Do triangular bandages expire?
Usually not. Most triangular bandages are non-sterile cotton or calico with no use-by date. If yours shows an hourglass date, follow it. Replace any that are stained, torn or have been used.
Do conforming bandages expire?
Non-sterile conforming bandages usually have no use-by date. If the pack shows one, follow it. Replace a bandage that is soiled or no longer springs back.
Do bandaids and plasters expire?
Yes. Plasters are sealed and sterile, so the box carries an expiry date, usually 3 to 5 years after they were made. After that date sterility is no longer guaranteed and the adhesive often stops sticking well.
Does saline expire?
Yes. Sterile saline ampoules (pods) have a use-by date, usually 3 to 5 years after they were made. Each pod is single use: once opened, use it or throw it out. Discard any that are cloudy or damaged.
Do instant cold packs expire?
Yes, usually after 2 to 3 years. The chemicals inside can break down so the pack no longer gets cold. Replace any that are leaking, punctured or already activated.
Do gauze pads and sterile dressings expire?
Sterile gauze and dressings carry a use-by date, often up to 5 years. They are only sterile while the seal is intact and the date has not passed. Non-sterile gauze generally has no expiry.
Do antiseptic wipes expire?
Yes, usually after 2 to 3 years. The wipes dry out and the antiseptic weakens, even in a sealed sachet.
Do emergency foil blankets expire?
Most have no use-by date. Replace a blanket if its pack has been opened or the foil is torn.
Is it safe to use an expired bandage or dressing?
The main risk is with sterile items on open wounds: after the use-by date, sterility is no longer guaranteed. An out-of-date non-sterile bandage still gives support, but may have lost its stretch. Use in-date items where you can, and in a workplace kit replace anything expired at the next check.
How do I tell an expiry date from a manufacturing date?
Medical packaging uses standard symbols. An hourglass marks the use-by (expiry) date. A small factory shape marks the date it was made. LOT is the batch number. If a pack shows only a manufacturing date, the maker has not set an expiry, so replace the item based on its condition.
How long does a first aid kit last?
The case itself does not expire, but the contents do. A kit is only as current as its earliest-dated item. Check the kit after each use and at least once every 12 months, and replace anything expired or used.
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?
This is general information, not medical advice.
- 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 point of view, a kit with expired items doesn't meet the Code of Practice, which asks that items are within their expiry dates.
Best Practices for Expiry Management
- First In, First Out (FIFO) — when restocking, place new items behind existing ones
- Regular checks — the Code of Practice minimum is after each use and at least every 12 months; busy or high-risk kits are often checked monthly or quarterly (how often to check)
- 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
