By the end of this course, participants will:

1. Understand the fundamental principles of toxicology and their application in HSE.
2. Learn how to identify, evaluate, and manage chemical hazards.
3. Gain insight into toxicokinetics and toxicodynamics of substances.
4. Explore methods for conducting workplace exposure assessments.
5. Understand regulatory requirements and compliance related to toxicological risks.
6. Develop strategies for emergency response to chemical incidents.
7. Create actionable plans to minimize toxicological risks in workplace settings.
