All Local Exhaust Ventilation (LEV) systems require a Thorough Examination and Test (TExT) or as more commonly known LEV testing / COSHH testing at least once in every 14 month period, or more frequently depending upon the application / process.
It is a requirement of Health and Safety at Work Act 1974 and regulation 9 of the Control of Substances Hazardous to Health (COSHH) regulations, that Local Exhaust Ventilation systems (LEV) must be monitored and maintained to ensure that they are in good working order. These include systems which remove airborne dust, fumes and vapours.
When correctly designed LEV systems protect their users from hazardous processes, by providing engineering control of process dust, fumes and vapours. These systems should be checked by a qualified engineer who holds a recognised qualification. The recognised qualification needed for LEV testing / COSHH testing systems, is the BOHS P601 – Thorough Examination and Testing of Local Exhaust Ventilation systems (LEV).

Further guidance and information on Local Exhaust Ventilation (LEV) can be found on the HSE website of in the HSE Guidance HSG258 – Controlling Airborne Contaminants at Work: A guide to local exhaust ventilation (LEV). https://www.hse.gov.uk/pubns/priced/hsg258.pdf.
Chapter two in HSG258 outlines the roles and responsibilities for LEV systems, from the system user, to the LEV Service provider who provides the statutory LEV testing (TExT) inspection.
All new and existing LEV installations require a commissioning report to be issued, which can be used as a benchmark for subsequent future tests. All systems require this mandatory documentation from a large centralised dust control system to a single mobile weld fume control unit. HSG258 outlines the requirements for commissioning reports and the required competency of the commissioning engineer. The P601 qualification held by engineers who undertake Routine LEV testing (TExT) is not a demonstration of sufficient competence to undertake commissioning of LEV systems.
Our commissioning engineers hold the P602 – Basic Design principles of Local Exhaust ventilation Systems, along with the advance proficiency certificate P604 – Performance Evaluation and Management of Local Exhaust Ventilation Systems (LEV).
The HSE has produced simple guidance leaflet – INDG408 - Clearing The Air -https://www.hse.gov.uk/pubns/indg408.pdf - to help the employer choose a supplier of LEV equipment or LEV service provider.
