3M 7000002409 Probed Test Plugs E-a-rfit

Product Description

The 3M 7000002409 Probed Test Plugs are a specially modified version of the standard 3M 1100 earplug, fitted with a probe tube that enables quantitative fit testing through the 3M E-A-Rfit Validation System. These plugs are manufactured strictly for fit-testing purposes and cannot be used as hearing protection devices. Safety and industrial hygiene professionals use them during workplace hearing conservation programs to verify proper earplug fit for employees. The probe tube design allows the E-A-Rfit system to measure the attenuation achieved during a live fit test, generating a personal attenuation rating for each tested individual.

These test plugs are used in occupational health and safety settings where employers must document earplug fit performance for workers in high-noise environments. They are deployed by safety officers, industrial hygienists, and occupational health technicians conducting 1100 and 1110 earplug fit testing sessions. The E-A-Rfit Validation System measures real-world fit rather than relying solely on labeled NRR values, making these probed plugs an essential tool in a compliant hearing conservation program.

Key Features

• Probe tube integrated into the standard 3M 1100 earplug body for direct compatibility with the E-A-Rfit Validation System
• Enables quantitative personal attenuation rating measurement during live fit testing
• Compatible with fit testing for both the 3M 1100 and 3M 1110 earplug models
• For fit-testing use only — not rated or approved for hearing protection
• Sold by the case with a minimum order quantity of one case

Compatibility

Designed for use with the 3M E-A-Rfit Validation System. Supports fit testing for the 3M 1100 and 1110 earplugs as stated by the manufacturer.

Installation Notes

These plugs are administered by a trained safety professional or industrial hygienist during a structured fit-testing session using the E-A-Rfit Validation System. No tools are required, but the operator should follow the E-A-Rfit system guidelines for proper probe tube placement before each test. These plugs must not be reused as standard hearing protection after testing. Follow your facility hearing conservation program protocols and applicable OSHA 29 CFR 1910.95 requirements when conducting fit testing.
