Industrial Hygiene & Site Assessments

Exponent’s industrial hygienists conduct site assessments to evaluate potential exposures to chemical, biological, and physical hazards in all types of media. We have broad experience in the field and are able to evaluate exposures in all types of media—air, water, food, and environmental surfaces. Our clients request site assessments for regulatory purposes, including compliance with OSHA regulations and California Proposition 65 reporting requirements, chemical spills or emergencies, and for litigation purposes.

Our industrial hygienists work across the country and internationally. We have assessed workplace chemical and dust exposures, warehouse and manufacturing facilities, construction sites, mining operations, hazardous waste sites, shipping vessels, office buildings, residential settings, and many others. We sample for a wide variety of contaminants, including asbestos, metals, PCBs, dioxins, furans, VOCs, PAHs, micro toxins, nanoparticles, bioaerosols including toxic mold and bacteria, pesticides, welding fumes, solvents, and other pollutants. We also design and implement large sample collection projects, and compile, analyze, and interpret the data produced, to address food, air quality, and water quality concerns.

Indoor air quality (IAQ) assessments and outdoor air quality assessments are performed regularly by our staff. We conduct investigations involving moisture and water intrusion, environmental mold, odors, and off-gassing from furniture and other materials. Our IAQ assessments can stem from claims related to Sick Building Syndrome (SBS). IAQ investigations are closely related to building ventilation,, so our staff is experienced in the evaluation of heating and air supply and conditioning systems (HVAC).

Most of our industrial hygienists are certified by state and professional agencies. For example, our staff includes Certified Industrial Hygienists (CIH) certified by the American Board of Industrial Hygiene (ABIH). Other industrial hygienists have several state certifications, such as the regulated California asbestos training certification and certified mold remediation consultants. Many of our staff are also certified hazardous material managers and certified environmental consultants.

In addition to our site sampling programs, we conduct technical reviews and analytical quality control review of sampling data for litigation purposes. These reviews involve evaluating the design, sampling collection techniques, and data and laboratory quality control practices.
