Did you know that first aid kits regularly need to be checked for damaged or outdated supplies? If it's been a while since you took a look at your inventory, follow these steps for keeping your kit up to date:
Dispose of any unsafe, opened or damaged supplies. Even if an open item has a resealable cap, it's safest to treat it as if it's cross-contaminated after one use.
Look at the expiration date on each item and dispose of any that are outdated. Items that have expired will not be as effective.
Finally, rotate your items so that the newest are in the back of the first aid kit.
