Do first-aid kits expire? Some items do.
A first-aid kit has no single expiry date, but many of the things inside it do. Sterile dressings, saline, wipes, gloves, cold packs and tape all age. Here is what to look for and how to stay ahead of it.
The short answer
Yes. St John Ambulance says items past their expiry date should be thrown away and replaced, because they may not work and can deteriorate, making them unsafe. Not every item has a date, but sterile items usually do.
Which items expire or wear out
- Sterile dressings, gauze and eye pads: the date is about sterility. Once the seal is broken or past the date, the item is no longer guaranteed sterile.
- Saline pods and eye wash: dated, and the pods can split.
- Plasters: lose their stickiness over time (St John Ambulance).
- Cleansing wipes: dry out and stop working.
- Gloves: old gloves perish and may not protect you from blood.
- Instant cold packs: carry a date. Check them, as an old pack you can't rely on is no use on match day.
- Sports tape: loses its stick, especially after a summer in a hot car.
How to read the expiry date
On medical packaging, the expiry date is usually printed next to an egg-timer (hourglass) symbol. It shows the year and month the item expires. Next to it you will often find a LOT number, which identifies the batch if there is ever a recall.
If a sterile item has no date, St John Ambulance suggests asking the manufacturer how long it can be kept. For non-sterile items without a date, use your judgement: does it still look and work as it should?
A whole kit sold with a single date on the label usually shows the earliest date of anything inside it. Items you add later have their own dates.
Planning for items without a date
When an item has no printed date, Benchkit uses a rough planning hint so it still gets checked. These hints are ours, not a manufacturer's rule. The printed date always wins.

Make the contents last longer
- Store the kit somewhere cool and dry, out of direct sunlight.
- Don't live out of the car. St John Ambulance suggests checking more often if a kit is kept in a vehicle or anywhere warm.
- Keep items in labelled pouches or compartments so dates are easy to see.
- Replace things as soon as they are used, so nothing is missing when you need it.
What to do with expired items
Take them out of the kit and replace them. The UK Health and Safety Executive's advice for workplace kits is to replace expired items and dispose of them safely. Don't keep expired sterile items "just in case": in a real emergency, nobody has time to check which pack is in date.
Then put the next date in a calendar. The kit check guide shows a quick routine.

Do plasters expire?
Plasters often carry a date, and even when they don't they lose their stickiness over time. Replace them when they stop sticking or pass the printed date.
Do bandages expire?
Sterile bandages and dressings carry an expiry date because sterility can't be guaranteed forever. Non-sterile bandages such as elastic or triangular bandages usually last much longer; check that they still look and work as they should.
What does the egg-timer symbol on a first-aid item mean?
It marks the expiry (use-by) date, shown as a year and month.
Can I use an expired first-aid item?
St John Ambulance advises replacing expired items because they may not be effective and can deteriorate. Keep your kit in date so you never have to decide in the moment.
How often should I check expiry dates?
St John Ambulance recommends checking a kit every six months, and more often if it is kept somewhere warm. For a team kit used every week, a monthly check in season is sensible.
