Quick answer
What is Hazardous Substances compliance?
COSHH compliance means identifying substances hazardous to health, assessing exposure risks and putting controls in place to prevent or reduce harm. HSE COSHH guidance covers chemicals, dusts, fumes, vapours, biological agents and other hazardous substances used or created at work. Records should show assessments, safety data sheets, controls, monitoring and reviews.
Who is responsible?
The duty falls on the employer whose work exposes people to hazardous substances. They must assess the risk, prevent or adequately control exposure, maintain control measures, provide information and training, and arrange monitoring or health surveillance where required.
How often is it due?
COSHH assessments should be reviewed when the substance, task, exposure route, workplace or evidence changes. Local exhaust ventilation usually needs thorough examination and testing at least every 14 months, with shorter intervals for some higher-risk processes.
What evidence proves it?
Keep COSHH assessments, safety data sheets, exposure-control records, LEV test reports, PPE requirements, air-monitoring or health-surveillance records where needed, training evidence and review history. Records should show what the substance is, who is exposed, how risk is controlled and when controls were checked.
How CertFlow helps
CertFlow links each substance to its assessment, data sheet, storage location, PPE, control measures and review dates. Teams can complete COSHH checks on mobile, attach evidence, schedule LEV or control reviews, and keep a searchable register for audits and site teams.
