What is a Local Exhaust Ventilation (LEV) system?

A Local Exhaust Ventilation system or LEV is a workplace fume and dust extraction system. They can be found anywhere that needs to protect workers and users of a system from the release of airborne contaminants that could pose health risks or impact the environment. These contaminants can include dust, fumes, vapours, gases, and other harmful substances.

Here are some common places where you might find LEV systems:

Manufacturing Facilities: LEV systems are often used in manufacturing plants to control and extract airborne contaminants generated through welding, cutting, grinding, and chemical processes.

Laboratories: Laboratories that handle hazardous substances use LEV systems to control fumes, vapours, or dust produced during experiments or testing.

Woodworking Shops: LEV systems are used to remove wood chips, shavings, and dust that can be generated during the woodworking processes.

Metalworking Shops: LEV systems can be found in metalworking facilities to control fumes or any particles that might be generated by metal cutting, welding, and grinding.

Chemical Processing Plants: Industries involved in chemical manufacturing often use LEV systems to extract and control the release of any hazardous chemical vapours and dust.

Foundries: LEV systems are also used in foundries to extract and control emissions produced during metal casting and other related processes.

Construction Sites: LEV systems are sometimes used on construction sites for example when concrete cutting or abrasive blasting, to control the dust and protect workers.

Pharmaceutical Manufacturing: Within pharmaceutical manufacturing, LEV’s are used to control the release of airborne contaminants during the production of drugs and pharmaceutical products.

Garages and Vehicle Repair Shops: LEV systems can be found in auto repair shops to capture and extract exhaust fumes.

Printing and Graphic Arts: Printing facilities utilise LEVS to control emissions from inks, solvents, and other substances used in the printing process.

Schools, colleges, and Universities: Within an education facility they may have laboratories, and wood and metal working shops, that will require an LEV to safely extract and control hazardous materials, dust and contaminants.

These are just a few examples, and the use of LEV systems can vary depending on the specific processes and activities that are being carried out.
