Local exhaust ventilation systems (LEV systems) are essential for keeping certain workplaces safe for employees. Industries such as food manufacturing, materials handling, chemicals, life sciences, pharmaceuticals, soft disposables, and general manufacturing, often have requirements for these due to the by-products and fumes generated during production.

What are LEV systems?
LEV systems remove harmful substances such as dusts, mists, gases, vapour and fumes out of the air.

An LEV system that has been appropriately designed and installed should extract air containing harmful contaminants, ensure they are contained and removed from any areas where people are working, and get rid of them safely.

LEV systems design considerations
Good design is essential when it comes to choosing LEV systems. A system that is poorly designed and doesn’t meet the requirements of the facility can not only prove costly to fix, but also risks employee health.

The Health & Safety Executive has guidance available on the minimum requirements which must be taken into consideration when designing an LEV system, and it’s essential that these are followed to ensure the system is fit for purpose.

An experienced LEV system designer will ensure that the system includes:
Fit indicators (e.g. pressure differential gauges) that allow the operator to check the system is working as expected
Allowances for comprehensive training on how to use, check and maintain the system
A user manual which includes details of how the system works, maintenance, checks and testing, performance benchmarks and replacement parts
A logbook to allow the operator to record checks and maintenance
