The continued widespread occurrence of occupational lung diseases in the UK has led to increasingly stringent guidelines and statutory requirements for Local Exhaust Ventilation (LEV).
In May 2008, Health and Safety Executive (HSE) published a new, comprehensive guide (HSG258) on LEV for designers, installers and examiners and detailed guidance for employers and their employees who depend on LEV to protect their health.
LEV systems must be tested every 14 months
The COSHH regulations require that all LEV systems are subject to a thorough examination. They also require most LEV systems to be tested every 14 months, including all oil mist, welding fume, smoke and dust extraction units that you currently have on site. This examination must be undertaken by a competent person and the tests and reports must conform to HSE standards. The HSG258 guideline on Controlling Airborne Contaminants provides the recommended procedures to achieve these statutory requirements.
