Moldex 6881 SparkPlugs Metal Detectable PlugStation Corded Earplug Dispenser — NRR 33dB, 150 Pairs

The Moldex 6881 SparkPlugs Metal Detectable PlugStation Corded Earplug Dispenser provides 150 pairs of Moldex SparkPlugs Metal Detectable NRR 33 corded foam earplugs in the PlugStation compact dispenser format — hearing protection specifically engineered for food processing, pharmaceutical, and other industries where foam earplug contamination of product is a metal detection or visual inspection program concern. The SparkPlugs Metal Detectable earplug incorporates a metal-detectable compound throughout the foam body, enabling detection by inline metal detection systems if the earplug falls into product. The high-visibility color (bright detectable coloring) provides additional visual detection capability. The SparkPlugs T-shape push-to-fit design — no rolling required, direct insert by grasping the flat top — provides NRR 33 maximum-standard attenuation with the insertion reliability that prevents the partial-insertion failures that diminish real-world attenuation of roll-down foam earplugs in food processing environments. The corded design retains the earplug at the neck during zone transitions and reduces loss in production areas where dropped earplugs could reach product lines.

Metal-Detectable Hearing Protection for Food Safety Programs

Food processing facilities with inline metal detection programs require that all PPE worn during production — including hearing protection — be either metal-detectable or X-ray detectable so that accidental product contamination can be caught before product leaves the facility. Standard foam earplugs fail both criteria: they contain no metal compound, and they are not visually distinctive enough to be reliably caught by visual inspection before product exit. A standard foam earplug that falls into product during filling, packaging, or processing can pass through inline detection undetected, creating a product safety incident.

The SparkPlugs Metal Detectable foam incorporates a metal-detectable compound throughout the foam body — not just a coating — ensuring that the earplug is detectable even if the foam is fragmented. The high-visibility color (typically bright blue, which is not a naturally occurring food color) provides the secondary visual detection layer: line workers, QC inspectors, and metal detection technicians can identify the earplug visually if it reaches an inspection point before the detection station. The combination of metal-detectable foam and high-visibility color provides dual detection capability that satisfies the contamination control documentation requirements of HACCP programs, BRC, SQF, and similar food safety management systems.

SparkPlugs Push-to-Fit in Food Processing Gloved Conditions

Food processing workers in production and packing areas typically wear single-layer food processing gloves or heavier barrier gloves that impair the finger dexterity required for roll-down foam earplug compression. SparkPlugs' push-to-fit T-shape design does not require finger compression — workers grasp the flat T-top through their gloves and push directly into the ear canal. The flat top stops at the canal entrance, providing the correct insertion depth indication through glove material. This glove-compatible insertion method is a significant practical advantage in food processing hearing protection programs where mandatory glove use during production conflicts with standard foam earplug insertion technique.

Compliance and Certifications

• ANSI S3.19 — SparkPlugs Metal Detectable NRR 33 tested under ANSI Method B
• OSHA 29 CFR 1910.95 — suitable for industrial hearing conservation programs
• Metal detectable — supports HACCP and food safety management system requirements
• Made in USA (earplugs)

Real-World Benefits

Metal-detectable + high-visibility provides dual contamination detection for food safety documentation. HACCP programs require documented identification of all foreign material risks in food production. Metal-detectable hearing protection provides the critical control point (inline metal detection) and the second line of defense (visual inspection) that food safety programs use to demonstrate due diligence in foreign material contamination control for hearing protection specifically.

Corded design reduces earplug loss risk in production environments. An uncorded foam earplug that falls from a worker's ear during production activity drops to a surface where it may reach a product line before discovery. The cord retains the SparkPlugs Metal Detectable earplug at the worker's neck if dislodged, dramatically reducing the probability of a production area earplug contamination incident.

Push-to-fit insertion works with mandatory production gloves. Food processing workers who must wear gloves during production can insert SparkPlugs Metal Detectable earplugs by grasping the T-top through their gloves — no roll-down compression required. This glove-compatible insertion supports consistent hearing protection use in production areas where glove-wear compliance would otherwise prevent correct foam earplug insertion.

Applications and Use Cases

• Food processing production lines — metal-detectable corded hearing protection for HACCP foreign material control programs
• Pharmaceutical and medical device manufacturing — detectable hearing protection for cleanroom and controlled area contamination control
• Beverage and packaged food facilities — BRC, SQF, and FSMA-compliant hearing protection for inline metal detection program documentation
• Gloved production workers — push-to-fit insertion for workers who cannot roll foam earplugs while wearing mandatory production gloves

Frequently Asked Questions

What metal detection equipment detects the SparkPlugs Metal Detectable earplug?

The SparkPlugs Metal Detectable earplug is formulated to be detectable by standard inline metal detection equipment used in food processing. Detection sensitivity depends on the specific metal detection system, aperture size, product characteristics, and operating parameters of the detection equipment in your facility. Verify detection of the 6881 earplug in your specific metal detection system before deploying as your food safety hearing protection standard. Contact Moldex for metal-detectable compound specifications and known detection equipment compatibility.

Can I use non-metal-detectable earplugs in a food processing facility?

Food safety management systems that include hearing protection as a potential foreign material risk (HACCP CCP or prerequisite program) should specify metal-detectable hearing protection for all production area use. Using non-detectable hearing protection in production areas creates a documented HACCP gap that can generate audit findings under BRC, SQF, FSSC 22000, and similar food safety management certifications. Consult your food safety team to determine whether hearing protection is documented as a foreign material risk in your specific facility's HACCP plan.
