Occupational Epidemiology

Identifying Patterns to Protect Workers

Understanding the connection between workplace exposures and health outcomes gives you the power to prevent problems before they impact your bottom line. Our epidemiologists use robust data analysis approaches to transform your existing health information into strategic insights. We help you:  

  • Identify and monitor health trends among worker populations 
  • Investigate the potential impacts of specific workplace exposures 
  • Develop preventative strategies to reduce occupational illnesses 

Our approach ensures decisions are grounded in science, helping organizations foster healthier, more resilient workforces. 

Occupational Toxicology

Expert Guidance for Hazard Management

You face complex decisions about chemical safety—especially with new substances or changing regulations. Our occupational toxicologists provide the scientific foundation you need to manage risks effectively while maintaining regulatory compliance and protecting your workforce. We evaluate:  

  • Toxicity and potential hazards and risks associated with specific substances or chemical mixtures  
  • Exposure pathways and dose–response relationships to establish health-based exposure limits 
  • Regulatory compliance challenges while also proactively understanding emerging risks  

These evaluations empower clients to manage risks effectively, safeguard employee health, and maintain compliance with occupational health and safety standards.

FAQs

When should we consider bringing in occupational health specialists?

Early engagement provides maximum value—ideally before introducing new processes, chemicals, or expanding operations. Our proactive approach helps you avoid costly retrofits and regulatory issues while establishing robust safety foundations from the start. 

How can you help us navigate TSCA requirements for workplace exposure assessments?

We specialize in conducting qualitative and quantitative exposure assessments that meet EPA requirements under TSCA Sections 4 and 5, including test order mandates, premanufacture notices, and consent orders. Our team prepares required documentation for regulatory submission while helping you optimize existing data and strategically identify what additional information is needed for approval. 

How does Integral's approach differ from typical occupational health and safety consultants?

We combine three scientific disciplines—industrial hygiene, epidemiology, and toxicology—under one roof, providing integrated solutions rather than fragmented services. This comprehensive approach ensures your safety programs are built on solid science, not just regulatory checklists. Additionally, Integral will coordinate with our broad network of professionals to assist with routine, regionally-based field efforts, when available, to more efficiently serve our clients.   

How do you ensure our workplace safety programs stay current with regulations?

Our team actively monitors regulatory changes and maintains relationships with key agencies like OSHA and EPA. We provide proactive updates and program adjustments, ensuring you’re always ahead of compliance requirements rather than catching up after changes occur.
