​Keeping Workplaces Safe: A Step-by-Step Guide to COSHH Assessments

Workplace safety is a cornerstone of good business practices, and adhering to regulations like the Control of Substances Hazardous to Health (COSHH) is essential. COSHH protects employees from harm caused by hazardous substances, ranging from toxic chemicals to everyday items like paint or dust. Failing to comply isn’t just risky—it’s illegal, with unlimited fines as potential penalties.

To meet these obligations, employers must begin by conducting a COSHH assessment. But what exactly does this involve, and how can it be done effectively?

What is a COSHH Assessment?

A COSHH assessment is a focused review of the risks and hazards associated with substances used or created in the workplace. Unlike general risk assessments that examine what makes a substance hazardous, a COSHH assessment zooms in on how and when these substances might cause harm.

Hazardous substances covered by COSHH include:

Everyday items like cleaning products or natural materials such as plant pollen can cause issues like dermatitis or asthma. However, specific materials—such as asbestos, lead, and radioactive substances—are excluded, as they fall under separate regulations.

Writing a COSHH Assessment Sheet

To create a thorough COSHH assessment, divide the information into four main sections:

Begin with the basics:

Hazards and Risks

Here, it details how the substance poses risks. For example, a pesticide may create harmful mists that can irritate skin or lungs. Consider:

• Who might be exposed? Employees? Maintenance staff? The public?
• How exposure happens: Look for hazard symbols like skull-and-crossbones (toxic) or a flame (flammable) on product labels for clues.

Control Measures

List the steps to reduce or eliminate risks:

• Provide appropriate personal protective equipment (PPE) like gloves or masks.
• Limit access to hazardous areas, such as rooms sprayed with chemicals.
• Ensure safe storage and disposal of substances.

Plan for emergencies as well, outlining first aid or evacuation procedures in case things go wrong.

Assessment

Finally, evaluate how well risks are controlled. Are tasks performed safely? Could control measures be improved? Regular updates to the assessment are vital if tasks or substances change.

Employer and Employee Responsibilities

COSHH compliance isn’t just about regulations—it’s about collaboration.

Why COSHH Assessments Matter

Conducting a COSHH assessment might feel time-consuming, but it’s critical. Lives and livelihoods depend on safe practices, and legal compliance helps protect everyone involved. By following these steps, businesses can ensure a safer workplace for all.
