3M E-A-R Classic Earplugs with Cord, 311-1101, Poly Bag, 200 Pair/Box
Innovative design, the first foam earplug featuring a cylinder shape
The 3M™ E-A-R™ Classic™ Earplugs set the industry standard for personal safety noise reduction as the worlds first foam earplug. Soft, slow-recovery foam is designed to mold to the shape of the ear canal and provide hearing protection. These disposable earplugs come with or without cords; an optional dispenser box is sold separately. A cylindrical shape is suited to fit most sizes, with a 7% smaller version also available for smaller ear canals and a 20% longer version for larger ear canals.
The first foam earplug featuring a cylinder shape. Even in humid environments, the moisture-resistant foam helps provide more comfort. They are available in standard, small and large sizes.
Hearing protection earplugs come with or without cords, and are available in different packaging types and quantities. Perfect for frequent visitors, these disposable earplugs can be distributed from a convenient dispenser box (sold separately).
Compatible with the 3M™ E-A-Rfit™ Dual-Ear Validation System
E-A-Rfit™ provides an accurate quantitative assessment of how much noise reduction a hearing protector provides to an individual worker.
1. ROLL and compress disposable foam earplugs into a very thin crease-free cylinder.
2. REACH around the head to pull the ear outward and upward to help straighten the ear canal. Insert compressed earplug well into the ear canal.
3. CHECK FIT after inserting earplug.
4.LISTEN to steady loud noise with earplugs in both ears. Cover ears with tightly cupped hands. Noise should sound about the same whether or not ears are covered.
CAUTION: For greater comfort and safety, remove earplug slowly with twisting motion to gradually break the seal.
