Chemical Hazard Assessments
Chemical Hazard Assessments (CHAs) are critical for understanding the safety and sustainability of the chemicals used in your products and processes. They help companies evaluate chemicals comprehensively and make informed decisions to minimize risks and maximize sustainability.
What is a Chemical Hazard Assessment (CHA)?
Chemical Hazard Assessments (CHAs) are fundamental to evaluating chemical risks linked to products and processes, enabling businesses to make safer and more sustainable choices in chemical management.
CHAs evaluate the potential for a chemical to have negative effects on human health, such as causing cancer or allergies, and on the environment. Unlike list screenings, which identify chemicals of concern based on limited criteria, CHAs delve deeper into a chemical’s intrinsic properties to assess factors including toxicity, persistence, and bioaccumulation. This approach provides a comprehensive understanding of potential hazards beyond the data in a standard Safety Data Sheet.
Whether you’re aiming to meet regulatory compliance, protect workers and customers, or reduce your environmental impact, understanding and conducting CHAs is essential for effective and responsible chemical management.

Why do Chemical Hazard Assessments matter?
Chemical Hazard Assessments play a critical role in chemical management — going beyond list screening alone — by providing detailed insights into the hazards associated with chemical use. By conducting CHAs, you can:
Protect your workers and customers
- Identify hazards to human health and make safer chemical choices
- Create products and processes to meet the highest safety standards
Go beyond regulatory compliance
- Stay ahead of rapidly changing sustainability requirements
- Understand regulatory drivers and anticipate future regulations
Safeguard environmental health
- Reduce the negative impacts of chemical hazards on the planet
- Phase out problematic chemicals for safer, more sustainable alternatives
Protect your brand
- Mitigate risks to avoid reputational damage
- Build customer trust by demonstrating chemical safety and sustainability
Overcoming challenges in conducting Chemical Hazard Assessments
Traditional CHAs can be complex, costly, and time-consuming, often taking weeks to complete. From list screening to referencing multiple data sources, the process often feels daunting for many companies. Common challenges include:
- Time-intensive: 79% of companies performing in-house CHAs find them time-consuming
- Costly: The average CHA costs between USD 3,000 and USD 10,000
- Complexity: Knowing where to start and gathering reliable data can feel overwhelming
