The BSC PREFERRED OCS1139 is a disposable slow-recovery foam earplug sold in a case of 500 pairs, intended for industrial, construction, and general trade environments where sustained hearing protection is required. Each plug is rated at a Noise Reduction Rating (NRR) of 29 decibels, meeting ANSI S3.19-1974 and CSA Class AL standards. The bright yellow color allows supervisors and safety officers to perform quick visual compliance checks across a work site. The foam compound is dermatologically tested, non-irritating, nonflammable, and moisture-resistant, making it suitable for environments with variable conditions.
The OCS1139 is appropriate for residential and commercial job sites, manufacturing floors, mechanical rooms, and any setting where sustained noise exposure exceeds safe thresholds. The case format is designed for bulk deployment by safety coordinators, facility managers, or trade contractors who maintain a stockpile for crew use. Each plug is roll-down style and requires no tools for insertion. This product is equivalent to part number S-18098, making it a direct substitute in existing supply programs.
Equivalent replacement for part number S-18098. Suitable for any standard roll-down foam earplug application requiring NRR 29 dB protection.
Roll the earplug into a tight cylinder before insertion, then pull the outer ear back and upward to straighten the ear canal before inserting. Hold the plug in place for several seconds until the foam expands to form a seal. Proper fit is required to achieve the rated NRR; an improperly seated plug will deliver reduced attenuation. Discard after single use or when visibly soiled.
