When Fatima, a facilities manager at a Dubai manufacturing plant, discovered that three of her workers had developed respiratory issues within the same month, she knew something was seriously wrong. The investigation revealed inadequate control measures for chemical vapors in the production area—a clear violation of hazardous substance regulations that could have been prevented with proper COSHH training and assessment.
Fatima’s experience isn’t unique. Across the UAE and globally, thousands of workers face daily exposure to hazardous substances that can cause anything from minor skin irritation to life-threatening diseases. The difference between safe operations and workplace disasters often comes down to one thing: proper understanding and implementation of COSHH principles.
Whether you’re a safety manager, employer, supervisor, or worker handling chemicals, cleaning products, dust, fumes, or biological agents, this guide will help you understand what COSHH means, why it matters, and how to implement effective control measures.
What is COSHH?
COSHH stands for** Control of Substances Hazardous to Health**.
Originally introduced in the UK (1988, revised 2002), COSHH provides a structured approach to managing hazardous substances in the workplace. Its principles are widely adopted globally and align with UAE occupational health and safety regulations.
