LEV (local exhaust ventilation)

Each year workers in the United Kingdom contract lung disease or asthma because they have breathed in too much dust, fume or other airborne contaminants at work (e.g. flour dust in bakeries, mist from paint spraying, fumes from welding or solvents from painting).

A properly designed, maintained and operated local exhaust ventilation (LEV) system can remove airborne contaminants before people breathe them in and will protect workers' health.

Key issues

LEV systems need to be properly designed, installed, commissioned and regularly tested to ensure that the system works properly.

Most LEV systems need a thorough examination every 14 months. Some LEV systems for critical or high hazard processes may require more frequent thorough examination and testing.
