What is the First Step in a COSHH Assessment?

What is the First Step in a COSHH Assessment? : COSHH (Control of Substances Hazardous to Health) assessments are vital in workplaces where hazardous substances are used. These assessments ensure the protection of employees and others from potential health risks associated with these substances. When initiating a COSHH assessment, the first step is crucial as it sets the foundation for a thorough evaluation of potential risks and necessary control measures.

The primary goal of this initial step is to identify and gather information about hazardous substances present in the workplace. Identification involves recognizing all substances that could pose a risk to health, ranging from chemicals and fumes to biological agents.

Understanding the Significance of Identification

Identification is crucial because without a clear understanding of the hazardous substances in use, it’s impossible to assess the risks they pose accurately. Employers need to recognize and document these substances to ensure appropriate control measures are in place to protect employees and others from harm.

Methods of Identification

Several key methods facilitate the identification process:

Types of Hazardous Substances

Understanding the various types of hazardous substances is fundamental. These could include chemicals, fumes, dust, gases, and biological agents, each requiring a distinct approach to identification.

Sources of Information

Utilizing safety data sheets (SDS), supplier information, and prior knowledge can aid in identifying hazardous substances. Consulting employees working directly with the substances is also valuable.

Assessing Risks

Assessing the risks associated with these substances involves evaluating their potential harm and exposure pathways. This helps prioritize control measures.

Practical Steps in Identification

The initial stage involves reviewing safety data sheets provided by suppliers. These sheets contain crucial information about the substances, their properties, and potential health hazards. Considering the quantities used and exposure levels further refines the assessment.


Identifying hazardous substances is the cornerstone of COSHH assessments. It’s a proactive step toward ensuring a safe working environment. By understanding and effectively identifying these substances, organizations can mitigate risks, protect their employees, and comply with regulations.
