Working with hazardous substances is a daily reality for many businesses, but it carries a significant legal and ethical burden. Control of Substances Hazardous to Health (COSHH) regulations exist to ensure that these risks are managed before they lead to life-altering illnesses.
What is a COSHH Assessment?
A COSHH assessment is a systematic review of your workplace to identify any substances that could be harmful to your employees' health. It isn't just a list of chemicals; it’s a proactive evaluation of how those substances are used, who is exposed to them, and what specific measures are in place to prevent harm.
Under the COSHH Regulations 2002, employers are legally required to prevent, or at least adequately control, exposure to hazardous substances.
Why are COSHH Assessments Important for Your Business?
Beyond being a legal "must-have," COSHH assessments serve several critical functions:
- Employee Safety: They prevent acute injuries (like chemical burns) and chronic illnesses (like occupational asthma or dermatitis).
- Operational Efficiency: Proper storage and handling reduce waste and prevent accidents that cause costly downtime.
- Legal Protection: In the event of an inspection or a personal injury claim, a documented COSHH assessment is your primary evidence of due diligence.
7 Steps to Conducting a Comprehensive COSHH Assessment
To ensure your assessment is thorough and legally compliant, follow these seven structured steps:
1. Identify Which Hazardous Substances Are Present
Start by walking through your site. Look for anything with a warning symbol on the packaging, but don't stop there. Hazardous substances also include:
- Fumes and Dusts: Created by processes like welding or woodcutting.
- Biological Agents: Such as bacteria or fungi.
- By-products: Waste materials or gases produced during chemical reactions.
2. Determine Who Is at Risk and How They Are Exposed
Identify everyone who might come into contact with the substance. This includes:
- Direct Users: The employees working with the substance daily.
- Indirect Users: Maintenance staff, cleaners, or contractors nearby.
- Vulnerable Groups: Pregnant workers or those with pre-existing respiratory issues.
How are these individuals exposed? Is it through inhalation, skin contact, or accidental ingestion?
3. Evaluate the Health Risks and Current Control Measures
Assess the severity of the risk. Is the substance a mild irritant or a carcinogen? Then, look at your current setup. Are you already using ventilation? Do you have spill kits? Determine if these current measures are actually effective or if they are "sticking plasters" on a larger problem.
4. Implement the Hierarchy of Control Measures
If the risk is too high, you must apply the Hierarchy of Controls in this specific order:
- Elimination: Can you stop using the substance altogether?
- Substitution: Can you swap it for a safer alternative?
- Engineering Controls: Can you use local exhaust ventilation (LEV) or enclosure?
- Administrative Controls: Can you reduce exposure time through rotas?
- PPE: As a last resort, provide gloves, masks, or eye protection.
5. Document Your Findings and Create an Action Plan
If you have five or more employees, you must record the significant findings of your assessment. This document should detail the hazards, the people at risk, and the specific controls you’ve implemented. It must be accessible to the employees who are actually doing the work.
6. Provide Comprehensive Information and Training
An assessment is useless if the workers don't understand it. You must provide training on:
- The risks identified.
- The correct use of control measures and PPE.
- Emergency response procedures (e.g., what to do if a chemical splashes in an eye).
7. Schedule Regular Reviews of Your COSHH Assessment
A COSHH assessment is a "living document." You should review it:
- Annually as a matter of best practice.
- Whenever a process or substance changes.
- If an accident or near miss occurs.
- If health surveillance suggests that current controls are failing.
The Legal and Financial Consequences of Not Having a COSHH Assessment
Failing to manage hazardous substances is a high-stakes gamble. If the Health and Safety Executive (HSE) or local authorities find you lacking, the consequences are severe:
- Hefty Fines: Fines for COSHH breaches are often based on turnover and the level of culpability, frequently reaching tens of thousands of pounds.
- Enforcement Notices: Inspectors can issue "Improvement" or "Prohibition" notices, effectively shutting down your operations until the risk is managed.
- Civil Claims: If an employee develops a long-term illness due to exposure, the resulting personal injury claims can be financially devastating.
- Criminal Prosecution: As discussed in our [Director’s Guide to Liability], serious negligence can lead to individual directors facing prison time.
Conclusion
Ultimately, a COSHH assessment is far more than a box-ticking exercise; it is a fundamental pillar of workplace safety. By following these seven steps, you aren’t just satisfying a legal requirement - you are actively protecting your most valuable asset: your people.
Hazardous substances don't have to be a liability if they are managed with precision and care. Whether you are a small workshop or a large industrial plant, the clarity provided by a robust assessment ensures that everyone goes home healthy at the end of the day.
