NRR 33 means the earplug achieved 33 dB of attenuation under ideal laboratory conditions. OSHA recommends applying a 50% derating for real-world use: (33 − 7) ÷ 2 = 13.0 dB effective attenuation. This accounts for fit variability in the field. In a 100 dB environment with properly fitted Softies earplugs, your estimated effective exposure is ≈ 87.0 dB — below the 90 dB OSHA PEL.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-bottom:6px;\"\u003eHow do I insert the Softies correctly?\u003c\/h3\u003e\n\u003cp style=\"margin-top:0;\"\u003eRoll-down insertion — roll the earplug between clean fingers to a thin cylinder, insert before it expands, hold in place for 20–30 seconds. Proper insertion is the most critical variable for achieving the rated NRR in the field. A poorly inserted earplug can provide significantly less protection than the rated NRR regardless of the earplug's quality. Moldex provides fit-check instructions with bulk packaging; training workers on correct insertion technique is an OSHA-required element of the Hearing Conservation Program under 29 CFR 1910.95(k).\u003c\/p\u003e\n\n\u003ch3 style=\"margin-bottom:6px;\"\u003eCan I reuse the Softies?\u003c\/h3\u003e\n\u003cp style=\"margin-top:0;\"\u003eThe Softies is a disposable earplug. Moldex recommends replacing after each shift or when the earplug is visibly soiled, compressed, or has lost its ability to roll back to shape. Do not wash and reuse disposable foam earplugs — washing degrades the foam matrix and reduces attenuation. Reusable alternatives in the Moldex lineup include the \u003ca href=\"\/collections\/moldex-earplugs\" style=\"color:#4fc3f7;text-decoration:underline;\"\u003eRockets, Alphas, and Jetz series →\u003c\/a\u003e for programs targeting reduced disposable waste.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-bottom:6px;\"\u003eWhen is the Softies not sufficient and what do I do?\u003c\/h3\u003e\n\u003cp style=\"margin-top:0;\"\u003eWith OSHA 50% derating, NRR 33 provides approximately 13.0 dB effective attenuation — protecting workers in environments up to approximately 103 dB(A). If your noise dosimetry documents exposures above 103 dB(A), a single earplug is not sufficient. Options: (1) add earmuffs over earplugs (adds ~5 dB above the higher NRR device), (2) switch to a higher-NRR earplug. Engineering controls (noise enclosures, vibration isolation, process modification) should always be evaluated as the primary controls before relying on additional PPE.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-bottom:6px;\"\u003eWhat is OSHA's Hearing Conservation Standard and does it apply to my workplace?\u003c\/h3\u003e\n\u003cp style=\"margin-top:0;\"\u003eOSHA 29 CFR 1910.95 applies to all general industry workplaces where any worker is exposed to a noise TWA at or above 85 dB(A). If your workplace has equipment, processes, or areas generating this level, you are required to implement a Hearing Conservation Program. This includes: noise monitoring, HCP enrollment, audiometric testing, HPD provision, training, and recordkeeping. For construction, OSHA 1926.52 applies. If you are not sure whether your workplace noise levels trigger the standard, contact a certified industrial hygienist for noise dosimetry measurements.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-bottom:6px;\"\u003eDoes the jar packaging affect the earplugs inside?\u003c\/h3\u003e\n\u003cp style=\"margin-top:0;\"\u003eThe jar protects earplugs from dust, moisture, and contamination between uses. Keep the jar closed when not in use. Do not store the jar where it is exposed to direct sunlight, heat, or solvent vapors, which can degrade the foam over time.\u003c\/p\u003e","brand":"Moldex","offers":[{"title":"Default Title","offer_id":44052676640856,"sku":"6683","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/1900\/0920\/files\/717YuzqiucL._AC_SL1200.jpg?v=1777623322","url":"https:\/\/wcsafety.com\/products\/moldex-6683-softies-foam-earplug-jar-nrr-33-50-pairs","provider":"WC Safety","version":"1.0","type":"link"}
