3M 7000029952 Corded Foam Earplugs 32db Nrr 200 Pairs

Product Description

The 3M 7000029952 is a corded, reusable foam earplug designed for hearing protection in high-noise industrial and trade environments. With a Noise Reduction Rating (NRR) of 32 decibels, these bullet-shaped plugs are inserted using the roll-down method and fit universal ear canal sizes. The blue cord keeps the pair together between uses, reducing loss on the job site. Each pack contains 200 pairs, making it practical for stocking a shop, service vehicle, or crew supply. The foam material is metal-detectable, a critical feature for food processing, manufacturing, and any controlled environment requiring contamination screening.

These earplugs are suited for use in loud mechanical environments including HVAC equipment rooms, generator areas, construction sites, manufacturing floors, and anywhere sustained noise exposure exceeds safe thresholds. The high-visibility yellow plug color allows supervisors and safety personnel to confirm proper PPE use at a glance. Universal sizing means a single SKU covers most workers without the need for multiple size SKUs. The reusable design supports multi-shift use when plugs are properly maintained and inspected between uses.

Installation Notes

Roll the foam plug between clean fingers until compressed, then insert into the ear canal and hold in place until the foam expands to form a seal. Inspect plugs before each reuse and discard any plug that is torn, hardened, or visibly soiled. Workers should follow applicable OSHA hearing conservation program requirements (29 CFR 1910.95) when using hearing protection in sustained high-noise areas.
