Feature surgical-grade, stainless steel ball bearings embedded in the grips to aid in locating the earplug if lost. Metal detectable earplugs were developed for food processing and other industries where it is critical to keep earplugs from contaminating products and processes. These “no-roll” style earplugs with paddle style grips provide quick, clean, and consistent placement of hearing protection. Simply pinch the grip between fingers and push to fit, which keeps the tip going into the ears clean even if hands are somewhat soiled with dirt, oil, grease, or some other contaminant. These earplugs have a Noise Reduction Rating (NRR) of 26 dB, CSA Class AL. However, research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit, earplug fitting skill and motivation of the user. It is recommended that the NRR be reduced by 50% to better estimate typical workplace protection.
