Local exhaust ventilation is an extract ventilation system that takes airborne contaminants such as dusts, mists, gases, vapour or fumes out of the workplace air so that they can't be breathed in. Properly designed LEV will: 1. collect the air that contains the contaminants 2. make sure they are contained and taken away from people 3. clean the air...
Every year over 2000 people die in Northern Ireland due to lung disease caused by airborne contaminants they have breathed in at work. If your work produces dust (e.g. flour dust in bakeries), mist (e.g. paint mist from spraying), fume (e.g. from welding), gas (e.g. carbon monoxide from furnaces) or vapour (e.g. solvents from painting), there may b...
