Understand your Local Exhaust Ventilation requirements
Effective Local Exhaust Ventilation (LEV) Units help keep employees safe at work by removing hazardous airborne substances. The Health and Safety at Work Act 1974 and Regulation 9 of the Control of Substances Hazardous to Health both state that LEV systems must be monitored and maintained to ensure they are in good working order.
Statutory requirements
There is a statutory requirement for systems to be tested every 14 months. In shorter time frames and in some cases, where metals articles are ground, abraded or polished for more than 12 hours per week for example, LEV systems are required to be tested every six months. Additionally, any processes where shot-blasting is carried out or if systems are involved in the cleaning of metal castings, they need to be assessed every month.
An effective LEV inspection comprises three stages:
- A thorough visual examination to verify that the LEV is in efficient working order
- Measurement and examination of the technical performance to check conformity with commissioning or other sources of relevant information
- Assessment to check the adequacy of control of work exposure
