As a safety professional, you know how to read a Safety Data Sheet (SDS). You can identify hazards, check for PPE requirements, and ensure compliance. But is that enough?
What happens when a worker asks why a substance is dangerous? Can you explain how that solvent can affect their liver, or why that dust is a long-term lung hazard?
This is the gap between compliance and true competence. It’s the “why” behind the hazard, and it’s what separates a good safety professional from a great one.
That “why” is exactly what you will learn in the internationally-recognized OHTA 507: Health Effects of Hazardous Substances training course.
Go from “What” to “How” and “Why”
This intensive course, offered by Gradi Health & Safety Limited, is designed to give you a foundational understanding of toxicology and human biology. It’s not about memorizing regulations; it’s about understanding the science that regulations are built on.
By the end of this course, you will be able to:
- Speak the Language: Define and use common toxicological terms with confidence.
- Trace the Path: Describe the main routes (inhalation, skin, ingestion) by which hazardous substances enter the body and what happens next (absorption, distribution, and excretion).
- Identify the Enemy: Recognize the health risks of common substances, from asphyxiants and irritants to carcinogens and sensitisers.
- Understand the Target: Explain how different substances target specific organs like the lungs, skin, nervous system, and kidneys.
- Connect Work to Health: See the direct link between industrial processes (like welding, painting, and foundry work) and the specific health effects they can cause.
- Read the Science: Gain a basic understanding of epidemiology to better interpret studies on workplace health risks.
Who Should Attend?
This course is essential for:
- EHS & Safety Professionals who manage chemical safety programs.
- Industrial Hygienists (new and experienced) looking to refresh or solidify their toxicology knowledge.
- Occupational Health Nurses and medical staff.
- Operations & Plant Managers responsible for high-hazard processes.
- Anyone who wants to move beyond simply “managing” chemicals to truly understanding them.
