What is a COSHH Risk Assessment? 5 Essential Steps in Chemical Safety
Working with chemical substances in industrial facilities, laboratories, or workshops poses serious occupational health and safety risks if not properly managed. The globally recognized COSHH (Control of Substances Hazardous to Health) regulations, which ensure the control of dangerous substances, act as the gold standard for businesses.
In this guide, we detail how to conduct a COSHH risk assessment in 5 essential steps to ensure legal compliance and enhance operational safety in your workplace.
What is COSHH and Why is it Important for Businesses?
COSHH is an occupational health and safety regulation originating in the United Kingdom, yet recognized worldwide as a gold standard reference, aimed at controlling substances hazardous to health. It covers not only toxic chemicals but also dust, vapors, fumes, and biological agents generated during the production process.
Conducting an effective chemical risk assessment:
Protects employees from occupational diseases.
Minimizes the risk of workplace accidents and associated costs.
Eliminates the risk of facing penalties during legal inspections.
How to Conduct a COSHH Risk Assessment in 5 Steps?
For a successful and legally compliant risk assessment, it is essential to fully implement the following systematic steps:
1. Identify Chemical Hazards
The first step is to compile a complete inventory of all hazardous substances on site.
Carefully review the Safety Data Sheets (SDS) obtained from suppliers.
Make sure to identify any by-products formed as a result of reactions on the production line (e.g., welding fumes or wood dust).
2. Determine Who Might Be Harmed and How
Determine which personnel are exposed to these chemicals and how often. Include not only line operators but also maintenance teams, cleaning staff, and visitors in the analysis. Clearly define the route of entry of the hazardous substance into the body (inhalation, ingestion, or skin contact).
3. Evaluate the Risks and Apply the Hierarchy of Control
Question the adequacy of existing safety measures. In occupational health and safety, it is essential to resolve the risk at its source. To do this, apply the Hierarchy of Control table below:
Control Method Implementation Strategy
Elimination Remove the hazardous chemical completely from the process.
Substitution Replace the current substance with a safer alternative for the environment and human health.
Engineering Controls Cut off contact by installing local exhaust ventilation (LEV) systems.
Administrative Controls Limit personnel's working time with chemicals and provide regular training.
PPE (Personal Protective Equipment) Enforce the use of appropriate masks, protective gloves, and goggles suited for the environmental conditions.
4. Record the Findings and Create an Action Plan
Compile all findings into a written COSHH assessment report. Create a clear action plan detailing who will implement the newly identified safety measures and when.
5. Review and Update the Risk Assessment Periodically
Update the document immediately when a new chemical is introduced, a process changes, or a "near miss" incident occurs. Even if there are no changes, reviewing the system at regular intervals is a legal requirement.
