I'm back at it again, making first aid its for a County department. I need any real life knowledge about expiration of some materials we want to stock, aiming for near-zero expiration kits to save money and time.
Benzalconium Chloride (Zephiran) pledgettes (wipes): I dont see expiration dates on them, have not found evidence they outdate.
Chemical light sticks: I see "sell by" dates on some and not others. My experience is they stay useable for many years, if not permanently. Anyone have different experience?
Chemical cold packs (ammonium nitrate and water/antifreeze): anyone have one fail to work due to expiration? I know the am-ni can get hard from consolidating, but if the water hits it, it still gets cold.
Lastly, water or rinse. I'm telling the truck users to bring potable water and use it for rapid rinse, but is there something that lasts better longer than sterile water? (I assume normal saline will outdate, and in a basic elementary first aid layperson situtation water is better than nothing). Maybe the old "survivalist" canned water? I have some potable water pouches that have two or three year outdates.
Your experience please.
