COSHH Assessments Made Simple: What Every Employer Must Know

Every employer in the UK has a legal duty to protect their workforce from exposure to hazardous substances. From cleaning chemicals to industrial dusts and fumes, these risks are often hidden in plain sight. Under the Control of Substances Hazardous to Health (COSHH) Regulations 2002, employers must carry out a COSHH assessment - not just as a tick-box exercise, but as a cornerstone of workplace safety and compliance.

At Sysco Environmental, we know that managing COSHH obligations can feel complex. This guide breaks it down into simple steps so you can protect your workforce and stay fully compliant.

A COSHH assessment is a structured review of all the substances in your workplace that could harm health. It looks at: 

• What the substance is (chemicals, dusts, fumes, biological agents). 
• How workers may be exposed (inhalation, skin contact, ingestion). 
• The level and duration of exposure compared to Workplace Exposure Limits (WELs). 
• The controls currently in place, and whether they are effective. 
• Further actions needed to reduce risks. 

The end result should be clear documentation that proves you are meeting HSE requirements and protecting your employees. 

Failing to conduct proper COSHH assessments can have serious consequences: 

• Health impacts: Long-term respiratory issues, skin conditions, cancers, and chronic illnesses. 
• Legal penalties: HSE can issue fines, enforcement notices, or even prosecution. 
• Reputation damage: Unsafe workplaces affect staff trust and client confidence.

By contrast, a strong COSHH process gives you confidence during inspections and builds a safer, more productive workforce. Sysco Environmental offers a complete range of occupational exposure monitoring, environmental assessments, and workplace assessments solutions to: 

1. Identify hazardous substances - including everyday cleaning products, solvents, fumes, or dusts. 
2. Review how staff use them - who is exposed, and under what conditions.
3. Measure exposure - monitoring actual workplace levels against HSE Workplace Exposure Limits. 
4. Evaluate current controls - extraction systems, PPE, ventilation, or substitution. 
5. Recommend improvements - practical solutions to reduce risks. 
6. Document findings - a report with clear, audit-ready evidence. 
7. Review regularly - COSHH assessments are not one-off; they must be updated when processes, substances, or regulations change.

Common Mistakes Employers Make: 

• Relying only on safety data sheets without site-specific assessments. 
• Failing to measure real exposure levels in the workplace. 
• Poor record-keeping, leaving no evidence for inspectors. 
• Treating COSHH as paperwork only, not a live safety process. 

These mistakes put businesses at risk of non-compliance and, more importantly, put workers’ health on the line.
