I always use ear plugs, but it amazes me how many people don't know how to fit them properly.
I have seen so many just stuffing them into the end of the earlobe - this dos not work
This is how i was told to do it - especially when working in and around the grinding mills in a coal fire power station and 400kV 10,000 psi Air Blast Circuit Breakers
1. Roll the earplug into a tight cylinder. In order for earplugs to fit into your ear canal, you must roll the foam so that it forms a tight cylinder. This makes it easy to slide earplugs into your ear so that you get a proper fit.
2. Lift the top of your ear to open the canal. Itís impossible to insert earplugs correctly without pulling on the top of your ear. Otherwise, the canal is too closed off to reach. You will need to grab the top part of your ear and lift slowly. If opened properly, you will feel air coming into the canal.
3. Insert the earplug into the open canal. If you opened the ear canal properly, you should be able to slide the earplug in easily. If the canal isnít open enough, you will find yourself trying to squish the earplug into place.
4. Hold earplug in place until the form expands. The foam will take a bit of time to expand. If you simply insert the earplug and then pull your hand away, the earplug will pop out. Instead, you need to gently hold the plug in place until the foam fully expands. This ensures that the earplug blocks out as much noise as possible.
5. Repeat Steps 1 Ė 4. Itís important to insert one earplug at a time. Otherwise, the foam will expand before you can begin work on the second ear.
It may take a few tries before youíre able to insert earplugs properly.
If you have trouble getting the canal open, make sure to re-roll the earplug so that the foam is tight.
If earplugs donít seem to be doing their job, even after several attempts, try buying a new brand.
Forcing earplugs into place can cause your ears to ache.
Wash your hands before you insert earplugs.
Once rolled, insert earplugs immediately or the foam will expand too much.
