Rated at a Noise Reduction Rating (NRR) of 33 dB and classified CSA Class AL, these earplugs are engineered to seal the ear canal securely while maintaining wearer comfort during extended shifts. An orange fitting ring serves as both an insertion depth guide and a quick visual compliance indicator for supervisors and safety personnel. Regular size fits most adult ear canals. Supplied in a poly bag packaging to keep earplugs clean prior to use, these are sold by the box.\u003c\/p\u003e\u003cp\u003eThese earplugs are suited for industrial and commercial environments where hazardous noise levels are a daily concern. Recommended applications include assembly, machining, grinding, chipping, chiseling, drilling, riveting, sanding, sawing, welding, painting, and heavy equipment operation. They are widely used across agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceutical industries. The earplugs are test compatible with the 3M E-A-Rfit Validation System, supporting formal fit-testing programs. A licensed safety officer or industrial hygienist typically oversees earplug program compliance in regulated worksites.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNRR 33 dB rating with CSA Class AL classification for high-noise environments\u003c\/li\u003e\n\u003cli\u003eSoft, slow-recovery polyurethane foam for comfortable extended wear\u003c\/li\u003e\n\u003cli\u003eOrange fitting ring guides proper insertion depth and enables visual compliance checks\u003c\/li\u003e\n\u003cli\u003eEasy roll-down insertion; foam expands to conform to the ear canal shape\u003c\/li\u003e\n\u003cli\u003eCompatible with the 3M E-A-Rfit Validation System for fit-testing programs\u003c\/li\u003e\n\u003cli\u003ePoly bag packaging keeps earplugs clean before use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eTest compatible with the 3M E-A-Rfit Validation System.

Always wash hands before handling earplugs to prevent contamination. Per OSHA 29 CFR 1910.95, a hearing conservation program should include proper fit verification. Note that 3M recommends reducing the stated NRR by 50 percent when estimating real-world noise attenuation during typical use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoise Reduction Rating (NRR)\u003c\/strong\u003e: 33 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCSA Classification\u003c\/strong\u003e: Class AL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyurethane foam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cstrong\u003ePackage Type\u003c\/strong\u003e: Box\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.78 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 19.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 12.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 31.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 10080529110593\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000002307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344686055730,"sku":"7000002307","price":941.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536161.jpg?v=1782040341","url":"https:\/\/voomisupply.com\/products\/3m-7000002307-disposable-foam-earplugs-nrr-33-db-regular","provider":"Voomi Supply","version":"1.0","type":"link"}
