Field-Based Sampling & Exposure Assessments — OR, WA & ID

Industrial Hygiene & Exposure Monitoring

What Our Industrial Hygiene Services Include

  • Personal and area air sampling for respirable crystalline silica, welding fumes and metals, total and respirable dust, volatile organic compounds (VOCs), and other contaminants

  • Noise dosimetry and sound level surveys for hearing conservation program compliance

  • Exposure assessments to determine respirator, PPE, and monitoring requirements

  • Written program support based on sampling results (respiratory protection, hearing conservation, silica)

Safety Northwest provides field-based industrial hygiene services to help employers understand and control workplace exposures. Our team performs on-site sampling and exposure assessments, with laboratory analysis through AIHA-LAP accredited labs, and delivers clear written reports that compare results to Oregon OSHA, Washington L&I, and federal OSHA limits.

Common Workplace Exposures We Measure & Help You Control

  • Respirable Crystalline Silica & Dust

    Field Testing Method:

    Personal breathing-zone pumps and area air sampling during cutting, grinding, batching, or manufacturing

    Regulatory & Program Outcome:

    Evaluates compliance against Oregon OSHA and Washington L&I Permissible Exposure Limits (PELs) and informs written Silica Exposure Control Plans.

  • Welding Fumes & Airborne Metals

    Field Testing Method:

    In-helmet and breathing-zone sampling for hexavalent chromium, manganese, iron oxide, lead, and other metals.

    Regulatory & Program Outcome:

    Determines engineering control effectiveness and exact respiratory protection requirements for fabrication and metalworking crews.

  • Volatile Organic Compounds (VOCs) & Chemicals

    Field Testing Method:

    Passive badges and active sorbent tube sampling in spray booths, finishing areas, and production lines

    Regulatory & Program Outcome:

    Establishes baseline chemical exposure profiles and updates your Hazard Communication, ventilation, and PPE protocols.

  • Occupational Noise & High-Decibel Equipment

    Field Testing Method:

    Full-shift personal noise dosimetry badges and octave-band area sound level mapping.

    Regulatory & Program Outcome:

    Identifies whether noise reaches action levels (85 dBA TWA) requiring a formal Hearing Conservation Program, audiometric testing, and hearing protection.

Clear Answers—Not Just Lab Spreadsheets

Whether you need a one-time baseline assessment or recurring monitoring, we scope the work to your operation and explain what the numbers mean for your crew. Every report includes accredited laboratory certificates from AIHA-LAP accredited facilities, side-by-side comparisons with applicable state and federal exposure limits, and practical next steps for engineering controls, work practices, and PPE.
