A Local Exhaust Ventilation (LEV) system is an engineering control measure designed to reduce employee exposure to airborne contaminants in the workplace by capturing the emission at source and transporting it to a safe emission point or a filter/scrubber.

What kinds of contaminants does a LEV system remove from the workplace?

A LEV system works by extracting the air away from the workplace and removing the contaminants within the air. Types of contaminants a LEV system removes from the air include:

• Mould spores
• Welding fumes
• Gasses
• Vapour
• Smoke
• Dust
• Mist

• A hood of some kind, where the contaminants enter the system
• Ducting, which safely transports the contaminants to a filter/cleaner/exhaust point
• Air cleaner/filter/scrubber
• Air mover: a fan to power the system
• Discharge: a safe point for the pollutants to exit

According to HSE, it is estimated that in 2018, 12,000 lung disease deaths were linked to past exposures in the workplace.

A LEV system is designed to protect the health of employees by removing the airborne contaminants and preventing harmful exposure to them.

Although it is not required by law to have a LEV system in place, the law requires employees to be protected from harm in the workplace. Specific legislation such as the Health and Safety at Work Act and COSHH requires employers to protect their employees if they are exposed to harmful contaminants, and in many cases, a LEV system is the solution.
