In reply to compost:
> It prompted me to dig into the first aid kit I've had at the bottom of a pack for ages and I'm now thinking it's likely that the plasters are no longer sticky and the sterile dressings may not be sterile! How often do you review and refresh what's in your kit?
Sorry for the delay in replying (and thanks for the supportive comments).
I don't really have any system for reviewing and refreshing my kit; I try to remember to replace anything I've used as soon as I get home so I don't forget, and add stuff / remove stuff at certain times of year or depending on the weather if relevant (e.g. sun block or midge spray) and at those times will usually have a quick check of the condition of everything else, e.g. to see if any sterile packaging has become open. Like you say, things like plasters have a habit of getting tatty and probably losing stickiness. The energy gels I used in that incident turned out to be BBE Nov 2022, but tasted fine and did the trick.
That's my personal approach ...on the ambulances, I hasten to add, I don't give people medicines 6 months out of date! We can only use in-date supplies (understandable for drugs but hugely frustrating for things like OPAs which are hard plastic tubes and would probably be fine in reality in 10 years time if the packaging is still intact!). Some items we'll use for training first, but most have to be disposed of unfortunately. If I date check everything on an ambulance (a useful thing to do when there are long waits outside hospital - depending on the condition of the patient obviously), I'll sometimes find something useful like wound glue, Mepore dressings or steristrips going out of date that month, so replace them and take the ones which would otherwise be binned for my first aid kit. I assume they'll be okay for a few months for my purposes and it saves a tiny bit from landfill (or delays that as the final destination at least). The majority of stuff isn't suitable for a personal first aid kit so is just binned directly or used for training then binned.
I might get better at checking and re-stocking my own first aid kit in future though, now that I've realised it's not just there as ballast in my rucksack and is actually very useful in the unfortunate event of being required...
