Expert Witness
OEH Solutions provides highly specialized expert witness services in matters involving occupational and environmental exposures, industrial hygiene practices, and regulatory compliance. Our experts have been actively engaged in toxic tort and premises liability litigation for decades, supporting both plaintiff and defense counsel in complex, high-stakes cases nationwide.
Our work includes comprehensive case review, exposure reconstruction, evaluation of historical industrial conditions, and critical analysis of industrial hygiene practices and safety programs. We develop scientifically defensible opinions grounded in established exposure science, regulatory standards, peer-reviewed literature, and real-world industrial experience.
Services include technical report preparation, deposition testimony, trial testimony, and consultation with legal teams on case strategy and scientific issues. We are experienced in analyzing a wide range of exposure scenarios, including chemical, biological, and particulate hazards in occupational, residential, and public environments. A core strength of our practice is the ability to translate complex scientific and technical concepts into clear, credible, and persuasive testimony that is understandable to judges and juries. Our opinions are developed with an emphasis on rigor, objectivity, and defensibility under cross-examination.
OEH Solutions is committed to providing independent, evidence-based expert analysis that meets the highest standards of scientific integrity and legal scrutiny in toxic tort and premises litigation.
Insurance Loss & Litigation Support
We provide independent industrial hygiene and environmental consulting services for insurance claims, product liability, construction defect, and remediation disputes. Our services include exposure assessments, moisture mapping, combustion by-product sampling, indoor air quality investigations, and evaluation of remediation effectiveness. We help insurers, attorneys, property owners, manufacturers, and other stakeholders understand potential exposures, determine the scope and impact of contamination, and develop scientifically defensible opinions for claims, litigation, and dispute resolution.
Exposure Assessment
We conduct detailed exposure assessments to quantify worker and environmental exposures to hazardous substances. This includes the design and execution of sampling strategies, personal and area air monitoring, bulk and surface sampling, and data interpretation. Our assessments are tailored to the specific exposure scenario, taking into account work practices, environmental conditions, and potential exposure pathways. Results are evaluated against applicable occupational exposure limits and guidelines, with clear recommendations provided to manage or mitigate identified risks.
Exposure Modeling
OEH Solutions utilizes advanced exposure modeling techniques to estimate exposures in situations where direct measurement is limited, unavailable, or requires supplementation. We literally wrote the book titled Mathematical Models for Estimating Occupational Exposure to Chemicals. Potential modeling includes retrospective exposure reconstruction, predictive modeling for proposed operations, and scenario-based risk evaluations. We apply validated models and defensible assumptions to estimate airborne concentrations, dose, and exposure variability. These analyses are particularly valuable in litigation,
regulatory review, and long-term risk assessment, where historical or hypothetical exposure conditions must be evaluated with scientific rigor.
OSHA Compliance
We assist organizations in achieving and maintaining compliance with OSHA standards and related regulatory requirements. Our experience serving as OSHA Compliance Officers offers intimate insight into the real-life inspection and enforcement process. Our services include comprehensive compliance audits, program evaluations, written program development, and site-specific hazard assessments. We provide practical guidance on standards such as Hazard Communication, Respiratory Protection, Silica, Asbestos, and other substance-specific regulations. In addition, we support clients during OSHA inspections, citations, and abatement processes, helping to reduce liability and ensure defensible compliance positions.
Indoor Air Quality
OEH Solutions assesses indoor air quality (IAQ) concerns in commercial, healthcare, and industrial environments. We investigate complaints related to odors, ventilation, mold, and airborne contaminants, utilizing targeted sampling and building system evaluations. Our approach considers HVAC performance, occupant activities, building materials, and potential contaminant sources. We provide clear findings and practical recommendations to restore acceptable indoor environmental conditions and address occupant health and comfort concerns.
Healthcare Industrial Hygiene & ICRA Consulting
We provide industrial hygiene and Infection Control Risk Assessment (ICRA) consulting for healthcare facilities, helping hospitals, clinics, and healthcare construction projects maintain safe environments for patients, staff, and contractors. Our services include ICRA compliance evaluations, moisture mapping, environmental assessments, and construction-related risk assessments.
We help healthcare organizations evaluate existing conditions, identify potential environmental hazards, and verify that construction and renovation activities are being performed in accordance with applicable ASHE ICRA 2.0 standards and best practices. Our industrial hygienists provide practical, independent oversight to support infection prevention, regulatory compliance, and effective risk management throughout healthcare construction and facility operations.

Health & Safety Program Development/Audit
OEH Solutions develops and evaluates health and safety programs tailored to the specific needs and risks of each organization. We create comprehensive written programs that align with regulatory requirements and industry best practices, including policies, procedures, and training components. For existing programs, we conduct detailed audits to identify gaps, inefficiencies, and areas of potential liability. Our goal is to deliver programs that are not only compliant, but also practical, enforceable, and integrated into daily operations.
Accident Investigation
OEH Solutions conducts thorough accident and incident investigations to identify root causes and contributing factors. We evaluate environmental conditions, work practices, equipment, and human factors to determine how and why an event occurred. Our investigations are structured, methodical, and defensible, supporting both internal corrective actions and external reporting requirements. We provide clear findings and recommendations aimed at preventing recurrence and strengthening overall safety performance.
OSHA Employer Liability
OEH Solutions provides detailed analyses of employer liability under OSHA regulations in both enforcement and litigation contexts. Our work evaluates whether an employer’s safety programs, hazard recognition practices, and field-level implementation meet applicable OSHA standards and the General Duty Clause. Drawing on extensive experience as former OSHA Compliance officers, we incorporate enforcement frameworks and interpretive guidance routinely used in inspections and citation development, including Compliance Policy Instructions (CPLs), the Field Operations Manual (FOM), and Letters of Interpretation.
A key component of our analysis involves the multi-employer worksite doctrine, which frequently governs citation issuance and liability allocation in construction, industrial, and complex operational environments. We assess employer roles as creating, exposing, controlling, or correcting parties and evaluate how these classifications influence OSHA citation exposure and shared responsibility. This framework is also critical in premises liability litigation, where overlapping contractor, subcontractor, and site owner responsibilities can significantly impact determinations of duty, knowledge, and control. Our evaluations provide clear, defensible opinions on how OSHA enforcement principles translate into real-world liability exposure across multi-party worksites.
Industrial Hygiene
OEH Solutions provides comprehensive industrial hygiene services focused on the anticipation, recognition, evaluation, and control of workplace hazards. We assess chemical, biological, and physical stressors across a wide range of industries, applying established methodologies to identify exposure risks and implement effective control strategies. Services include field evaluations, personal and area monitoring, ventilation assessments, hazard communication support, and control verification. Our approach emphasizes both regulatory compliance and long-term risk reduction, ensuring that workplace environments are protective of employee health while maintaining operational efficiency.
OEH Solutions is committed to delivering high-quality work that stands up to scrutiny whether in the field, the boardroom, or the courtroom. We take pride in being a trusted partner to our clients, providing not only technical expertise but also the insight and judgment necessary to navigate today’s most challenging environmental and occupational health issues.
