What is COSHH?

COSHH (Control of Substances Hazardous to Health)

COSHH helps protect employees from hazardous substances used in engineering, fabrication and manufacturing. If your workplace uses oils, chemicals, sprays, dusts, fumes or cleaning products, the COSHH Regulations are likely to apply.

Common Hazardous Substances

COSHH may apply to:

• Cutting oils and coolants
• Welding fumes
• Solvents and degreasers
• Paints and thinners
• Adhesives
• Grinding and cutting dust
• Cleaning chemicals
• Smoke and vapours
• Battery acids
• Metalworking fluids

Some substances can cause immediate injury, while others may lead to long-term health problems through repeated exposure.

Employer Responsibilities

Under COSHH, employers should:

• Identify hazardous substances in the workplace.
• Assess the risks to employees.
• Control exposure using suitable measures such as ventilation, extraction, safe storage and good housekeeping.
• Provide appropriate PPE where required.
• Ensure employees receive information, instruction and training on safe handling procedures.

What is a COSHH Assessment?

A COSHH assessment identifies hazardous substances, evaluates the risks they present and details the control measures needed to protect employees.

A typical assessment includes:

• Substance identification
• Hazard information
• Exposure risks
• Required PPE
• Safe handling procedures
• Storage requirements
• First aid information
• Spill response measures

Keeping COSHH assessments up to date helps businesses meet their legal duties and maintain a safer working environment.
