    Respirator Fit Testing

    OSHA-compliant respirator fit testing to ensure every worker’s protective equipment performs effectively. We provide both Qualitative and Quantitative Fit Testing (QNFT) for all respirator types, including N95s, half-face, full-face, and SCBAs. Our trained technicians use precise testing methods to verify proper seal and protection, helping employers meet OSHA 1910.134 requirements and maintain a safe, compliant workplace.

    School Hearing & Vision Screening

    State-required school vision and hearing screenings to support student health and learning. Our on-site testing identifies early vision or hearing issues that may affect classroom performance and ensures compliance with state mandates. Screenings are performed at designated grade levels or upon school entry to help schools maintain full regulatory compliance and promote student success.

    Hearing Testing

    On-site OSHA-compliant hearing tests to monitor and protect worker hearing health. Our mobile audiometric testing identifies early signs of noise-induced hearing loss and ensures compliance with OSHA’s Hearing Conservation Program. Required for employees exposed to noise levels of 85 dBA or higher (8-hour TWA), our certified technicians perform accurate audiometric evaluations using calibrated equipment for both temporary and permanent workers.

    Spirometry

    Comprehensive on-site spirometry testing for workplace medical surveillance. Our certified technicians perform OSHA-compliant pulmonary function tests to evaluate employee respiratory health, determine fitness for duty, and identify exposure-related health effects. Required by OSHA for asbestos, cadmium, coke oven emissions, and cotton dust programs, spirometry testing ensures workers are safe, protected, and compliant with federal standards.

 FAQs

  • OSHA compliance testing ensures your workforce meets federal safety standards for respiratory protection, hearing conservation, and workplace health. Precision Mobile Testing brings certified technicians directly to your facility to perform respirator fit, hearing, vision, and spirometry tests — keeping your business compliant with minimal disruption.

  • OSHA requires annual testing for respirator fit and hearing conservation programs. Spirometry and vision screenings are recommended annually or as part of periodic medical surveillance, depending on job type and exposure level.

  • Yes. We provide complete digital records and web-based data management, giving you instant access to all required OSHA documents and employee test results.

  • Qualitative fit testing (QLFT) uses a test agent like Bitrex or saccharin to check mask seal through taste or smell, while quantitative fit testing (QNFT) uses a specialized instrument to measure actual leakage around the respirator. Both methods meet OSHA’s Respiratory Protection Standard (29 CFR 1910.134).

  • Each test typically takes 10–15 minutes per employee, including mask fitting, seal checks, and documentation. We can test up to 4 people at the same time.

  • We can fit-test all brands and models of tight-fitting respirators, including N95s, half-face, full-face, and SCBAs.

  • OSHA requires annual audiometric testing for employees exposed to noise levels of 85 dB or higher. Precision Mobile Testing provides on-site baseline and annual hearing tests with web-based tracking and comparison reports.

  • Most facilities can test 6–8 employees per hour using our mobile testing units or on-site setup, minimizing downtime.

  • These tests monitor respiratory and visual function for employees who work in environments with potential airborne hazards or safety-sensitive tasks. Regular testing helps identify changes early and ensures compliance with industry safety programs

  • Spirometry measures lung function by recording the amount and speed of air an employee can exhale. Our technicians use OSHA-approved equipment and calibrations for accurate, reliable results.
