COSHH – What is it? What do you need to do?

Overview

This video introduces the UK’s Control of Substances Hazardous to Health (COSHH). It outlines employer responsibilities and offers practical steps to manage chemical risks in the workplace. ​

COSHH – What is it? What do you need to do?

The Control of Substances Hazardous to Health (COSHH) regulations aim to protect workers from the dangers of hazardous substances in the workplace. Employers have a legal obligation to control these substances and minimise the risks they present to employees’ health and safety. Failure to comply with COSHH can lead to serious health consequences and legal repercussions.

Employer Responsibilities Under COSHH

Employers must take steps to improve workplace safety by implementing the following measures:

1. Conduct a Risk Assessment

A primary requirement of COSHH is to identify hazardous substances detected in the workplace and assess the risks they pose. This includes considering how substances are used, stored, and disposed of and evaluating the level of exposure employees may face.

2. Implement Control Measures

Once risks have been identified, employers must introduce appropriate control measures to reduce or eliminate hazards. These may include:

• Ventilation Systems – Using local exhaust ventilation to remove airborne contaminants.
• Safe Storage and Handling – Ensuring hazardous substances are stored safely and handled using best practices.
• Personal Protective Equipment (PPE) – Providing gloves, masks, and other safety gear where necessary.

3. Provide Training and Information

Employees should know the risks of hazardous substances. Employers must also offer training on safe handling procedures, emergency responses, and proper use of control measures.

4. Monitoring and Health Surveillance

Regularly monitor exposure levels and conduct health checks for employees at risk. This helps detect potential health issues immediately and allows for timely intervention.

Implement Effective Control Measures

To further protect workers, employers should adopt a hierarchy of control measures, prioritising the most effective methods:

1. Substitution

Where possible, replace any hazardous substances with less harmful alternatives to reduce risk at the source.

2. Engineering Controls

Use equipment and technology to minimise exposure. Examples include:

• Fume Cupboards – Contain and extract harmful vapours.
• Enclosed Systems – Prevents the release of hazardous substances into the workplace.

3. Administrative Controls

Establish safe working procedures and provide proper training. This may include limiting access to hazardous areas and enforcing strict handling guidelines.

4. Personal Protective Equipment (PPE)

When other control measures are insufficient, provide employees with PPE such as gloves, masks, and eye protection as a last resort.

Review and Keep Records

To maintain compliance and workplace safety, employers should:

• Document Risk Assessments and Control Measures – Keep detailed records of all assessments, implement safety procedures, and conduct employee training.
• Conduct Regular Reviews – Periodically update risk assessments and control measures to ensure compliance with regulations.

Final Thoughts

Employers can protect workers from hazardous substances, reduce workplace risks, and comply with UK health and safety laws. You only need to follow COSHH guidelines and implement proper control measures. Regular assessments, training, and monitoring are also essential for maintaining a safe and legally compliant work environment.
