C&IH specializes in serving businesses, institutions, and organizations across a wide range of industries. While our consulting services are not designed for individual homeowners, our experts do engage in residential matters through legal cases, providing exposure assessments and objective scientific analysis.

C&IH provides industrial hygiene consulting to clients nationwide and internationally. Headquartered near Denver, Colorado, we combine regional accessibility and global reach, supported by our multidisciplinary team equipped to manage complex projects wherever our clients operate.

Investing in industrial hygiene services protects more than regulatory compliance, it safeguards the health of employees and the community and supports a work environment conducive to long-term productivity. Proactive exposure assessments help organizations identify risks early, implement effective controls, and avoid costly incidents or citations. By partnering with C&IH, companies gain access to scientifically objective expertise that strengthens both worker well-being and overall business performance.

Industrial hygiene monitoring is relevant in any workplace with chemical, physical, or biological hazards. Some of the industries C&IH support include:

• Industrial manufacturing

• Mining and metals

• Oil and gas, energy

• Healthcare and pharmaceuticals

• Electronics and technology

• Research laboratories

• Public institutions

Organizations across many sectors face complex exposure challenges that benefit from proactive monitoring to support compliance, protect employees, and maintain long-term operational performance.

C&IH assesses chemical, physical, and biological hazards across a wide range of industries. A few examples of common hazards include:

• Dusts and fibers: silica, asbestos, coal, nuisance dusts
• Ultra fine particles (UFP) and nanoparticles
• Solvents, gases and vapors: VOCs, benzene, ammonia, formaldehyde
• Metals and welding fumes: hexavalent chromium, lead, manganese, nickel
• Composites: fiberglass, styrene, resins, fiber-reinforced prepregs
• Non-ionizing radiation: RF, lasers, UV, microwaves
• Physical stressors: noise, vibration, heat/cold stress
• Other exposures: diesel exhaust, petrochemicals, paints, coatings, radon

Beyond these limited examples, every organization faces unique risks. Our role is to identify, evaluate, and manage exposures so your organization can protect employees, stay compliant, and maintain strong performance.

Exposure testing is required when employees may face chemical, physical, or biological hazards above established limits. Many organizations conduct testing proactively to identify risks, protect employee health, and demonstrate a strong commitment to workplace safety.

Most organizations reassess every one to three years to maintain compliance and ensure a safe work environment. Updates should also be made when new materials, processes, or equipment are introduced, or when significant operational changes may affect exposures.

Exposure monitoring helps organizations demonstrate compliance and prevent costly penalties by:

• Verifying exposure levels against OSHA limits and other regulatory standards

• Providing documented proof of hazard identification and control

• Guiding the implementation of engineering and administrative controls

• Documenting a proactive health and safety program

By addressing risks early, exposure monitoring supports both compliance and worker protection.

Exposure monitoring collects real-world data through direct measurement of workplace conditions. Exposure modeling uses scientifically validated tools, such as computational fluid dynamics (CFD), to estimate contaminant spread, validate sampling data, and evaluate engineering controls before implementation.

Engineering controls are the most effective way to reduce or eliminate workplace exposures. Examples include ventilation systems, process modifications, and equipment design improvements that address hazards at the source and reduce reliance on administrative measures or PPE.

An effective report goes beyond raw data to include detailed findings, comparisons to OSHA and other standards, and practical recommendations. C&IH focuses on providing actionable strategies that help leadership make informed decisions, maintain compliance, and protect employee health.

Industrial hygiene plays a central role in workplace risk management. At C&IH, we:

• Apply the National Academy of Sciences (NAS) risk assessment paradigm, adopted by the U.S. EPA

• Conduct hazard identification, exposure assessment, dose-response evaluation, risk characterization, and risk management

• Evaluate risks from chemical, physical, and biological agents using defensible scientific methods

• Deliver clear reports with actionable recommendations for compliance and long-term safety

• Help leadership move beyond compliance to proactively protect employees, communities, and business performance
