Designing LEV Systems

What is a LEV System?

Under Regulation 7 of the Control of Substances Hazardous to Health (COSHH) Regulations, employers are required to implement measures to protect their employees from exposure to harmful substances. Local exhaust ventilation (LEV) systems are the most common control measure available; designed to remove or reduce the risk of employee exposure to airborne substances.

LEV systems generally include a hood to capture or contain the airborne contaminants and a fan to extract the air through the hood. Systems may include other features, such as ductwork (to convey the contaminants through the system); air filtration (to clean the contaminants from the airstream) and a stack (to safely discharge the contaminants to atmosphere).

The Importance of Good Design

It is important that LEV systems are designed correctly and to the correct standards. There are many circumstances where these guidelines are not followed, and poorly designed systems are installed based on assumptions and guess work. The result is a system that will not effectively control contaminants and risk exposing employees to harmful dusts or fumes daily.

Guidance documents are available from the Health and Safety Executive (HSE), detailing the minimum requirements for designing, installing and commissioning a LEV system.

The designer should be a competent person with minimum P602 (or similar) qualification.

Designing LEV Systems

Design is the most important part of any LEV installation and commissioning process. Without correct design, an LEV system will not function efficiently. The specific contaminant will determine the requirements of the Local Exhaust Ventilation system. Once the contaminant has been identified, RCS LEV engineers will design the most appropriate and effective system to remove the contaminant from your work environment.
