It’s a question we are frequently asked – how do I clean my earplugs and earmuffs, along with how long can I wear them for?
It’s important to know how long you can use each type of hearing protection device (HPD) and how to care for it to maintain optimal hearing protection. In order to extend the lifespan of your HPD, proper use of it goes a long way – improper care of your earplugs may introduce a foreign substance and may not only pose a risk but might make insertion and/or retention harder.
The more often earplugs or earmuffs are worn it is possible that contaminants could build up, which leads to the importance of ensuring a clean HPD. The more often earplugs or earmuffs are worn, the higher the chances that contaminants are produced, which leads to the increased importance of preventing contaminants from entering the body. When it comes to earplugs especially, if chemicals that are hazardous to the skin are present on the surface of, or absorbed, into the body of a foam earplug, they may come into contact with your skin while you’re using the plug.
