Protecting Workers from Hazardous Substances with COSHH

Chemical Safety in the Workplace: Reducing Risk with COSHH Principles

Posted by James Robert on September 06, 2025

Workplace exposure to hazardous chemicals is a silent threat. Learn how COSHH principles help employers and employees manage risks, stay compliant, and protect health.

Introduction

Everyday workplace tasks — from cleaning to manufacturing — may involve hazardous substances. Without proper control, they can cause long-term illness or sudden injury. That’s why chemical safety and COSHH (Control of Substances Hazardous to Health) are essential.

Why Chemical Safety Matters

  1. Prevents occupational illnesses like asthma, dermatitis, and cancer
  2. Reduces risk of chemical burns, poisoning, or explosions
  3. Protects both employees and the environment
  4. Ensures compliance with international safety regulations

Key COSHH Principles

  1. Identify Hazardous Substances
  2. Label and assess all chemicals, even cleaning products.
  3. Assess the Risks
  4. Who is exposed? For how long? What are the effects?
  5. Control the Risks
  6. Use substitution, closed systems, ventilation, or PPE.
  7. Provide Training
  8. Employees must know safe handling, storage, and disposal.
  9. Monitor Health and Exposure
  10. Regular checks for workers in high-risk areas.
  11. Prepare for Emergencies
  12. Spill kits, eyewash stations, and first-aid training in place.

Practical Workplace Controls

  1. Use clear labels and Safety Data Sheets (SDS)
  2. Store chemicals in secure, ventilated areas
  3. Avoid mixing incompatible substances
  4. Keep PPE like gloves, masks, and goggles available
  5. Dispose of chemicals safely via approved methods
