3M 7100038298 Disposable Foam Earplugs Nrr 33 500 Pair

Product Description

The 3M 7100038298 is a box of 500 pairs of uncorded, disposable foam earplugs in a high-visibility yellow color. These earplugs are made from soft, pliable foam designed for extended wear comfort, making them well-suited for long shifts in loud industrial, mechanical, or construction environments. With a Noise Reduction Rating of 33, they provide a high level of hearing protection for workers exposed to elevated noise levels. The box uses a rapid-release dispensing design, allowing workers to grab a pair quickly without slowing down production or job site workflow.

These earplugs are intended for single-use hearing protection in occupational and trade settings where sustained high noise levels are a daily concern. Typical applications include HVAC equipment rooms, sheet metal fabrication, electrical panel installations near loud machinery, and general construction. The rapid-release dispensing box supports high-traffic PPE stations where multiple workers need quick access throughout a shift. Each box contains 500 pairs, making it practical for team use, job site supply caches, or ongoing facility PPE programs.

Installation Notes

Earplugs should be fitted by rolling the foam into a tight cylinder, pulling the outer ear up and back to open the ear canal, and inserting the plug until it seats properly. Workers should allow the foam to fully expand before entering a high-noise area. Proper fit is required to achieve rated NRR performance. Refer to applicable OSHA hearing conservation program requirements for training and fit-check protocols.
