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, including 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.
