Asbestos Expert Witness
RoseyFields provides expert witness and scientific consulting services involving asbestos exposure, mesothelioma, lung cancer, and other asbestos-related diseases. Our work integrates environmental forensics, industrial hygiene principles, exposure reconstruction, air dispersion modeling, contaminant fate and transport, epidemiology, and quantitative human health risk assessment to evaluate historical asbestos exposures in occupational, environmental, and consumer product settings.
Our investigations reconstruct historical asbestos exposures using peer-reviewed exposure studies, environmental sampling, occupational histories, regulatory guidance, dose-reconstruction methodologies, and accepted scientific approaches from EPA, OSHA, NIOSH, ATSDR, and IARC.
Occupational Asbestos Exposure
We evaluate historical occupational asbestos exposures across a wide range of industries and work environments, including maintenance operations, power plants, refineries, railroads, commercial buildings, industrial facilities, manufacturing operations, construction activities, shipyards, utilities, and mechanical equipment maintenance. Our analyses reconstruct airborne fiber concentrations, cumulative asbestos dose, exposure frequency, duration, and intensity using peer-reviewed industrial hygiene studies and accepted exposure assessment methodologies.
Representative Investigations
● Boiler and heating system maintenance
● Gaskets, valves, pumps, and packing materials
● Thermal insulation and pipe insulation
● Industrial maintenance operations
● Commercial and institutional facilities
● Railroad and transportation facilities
● Refineries and chemical facilities
● Occupational dose reconstruction
Consumer Talc, Baby Powder & Cosmetic Products
Epidemiological Studies Considered
RoseyFields evaluates asbestos exposure associated with cosmetic talc products, including baby powders, body powders, face powders, foot powders, loose cosmetic powders, and other talc-containing makeup products. Our investigations reconstruct historical asbestos exposures using peer-reviewed exposure studies, industrial hygiene data, product testing, epidemiology, and quantitative dose reconstruction. We evaluate direct users, bystander exposures, historical product sourcing, asbestos contamination of talc mines, laboratory testing, and the relationship between cumulative asbestos exposure and diseases such as mesothelioma and other asbestos-related illnesses.
Representative investigations include exposures associated with baby powder, body powder, face powder, foot powder, cosmetic talcum powder, loose face powders, makeup powders, and other cosmetic talc products. These evaluations address both direct consumer use and bystander exposure, focusing on identifying potential asbestos contamination and characterizing exposure pathways. We incorporate epidemiological studies in our analysis, including the table below
Buildings & Community Asbestos Exposure
RoseyFields provides expert witness and scientific consulting services involving asbestos exposures in commercial buildings, schools, universities, hospitals, industrial facilities, residential properties, and surrounding communities. Our investigations evaluate asbestos-containing building materials, including pipe insulation, boiler insulation, fireproofing materials, ceiling tiles, floor tiles, joint compounds, vermiculite insulation, and other legacy construction materials. We also assess exposures associated with building renovation, demolition, maintenance activities, asbestos abatement projects, and naturally occurring asbestos.
Our work integrates environmental forensics, industrial hygiene, air dispersion modeling, environmental sampling, contaminant fate and transport, exposure reconstruction, and quantitative human health risk assessment to evaluate potential asbestos exposures among building occupants, maintenance personnel, contractors, nearby residents, students, employees, and other community members.
Asbestos Dose Reconstruction Expert Witness
RoseyFields reconstructs historical asbestos exposure for occupational, bystander, product-use, maintenance, construction, railroad, insulation, and industrial-facility matters. The analysis can combine testimony, employment history, job duties, task frequency and duration, product or material information, historical personal breathing-zone and area measurements, published industrial hygiene studies, ventilation, work practices, housekeeping, respiratory protection, and distance from dust-generating activities. Where sufficient information exists, task-specific concentrations can be combined with exposure frequency, duration, and years worked to estimate cumulative asbestos exposure and evaluate the reconstructed dose in the context of relevant epidemiological evidence.
