Bsc Preferred OCS501 Half Facepiece Reusable Respirator

Product Description

The BSC PREFERRED OCS501 is a half facepiece reusable respirator sold in a case of 100 units, designed for trade and industrial environments where workers face exposure to particulates, gases, and vapors. NIOSH approved, the OCS501 provides respiratory protection at concentrations up to 10 times the permissible exposure limit when paired with properly selected, approved cartridges and filters. The swept-back cartridge design improves facial balance and widens the wearer's field of vision, which matters in confined or active work areas. Adjustable head straps allow for a secure fit across a range of face sizes. The unit can be fully disassembled for cleaning and reuse - only the cartridges and filters require disposal once spent.

This respirator is suited for residential and commercial job sites where respiratory hazards are present, including HVAC service, renovation, remediation, electrical work, and plumbing in environments with airborne particulates or chemical vapors. The case quantity of 100 makes it practical for larger crews or supply stocking. Because it is reusable, it reduces per-use cost compared to disposable alternatives. Equivalent to part number S-9752.

Installation Notes

Respirator fit-testing is required under OSHA 29 CFR 1910.134 before use in any atmosphere requiring respiratory protection. Cartridge and filter selection must be matched to the specific contaminants and concentrations present on the job site. Inspect the facepiece, valves, and straps before each use and retire any components showing cracking, deformation, or loss of elasticity. Cartridges and filters must be disposed of in accordance with local regulations when used to capacity.
