Workplace dust and fume extraction solutions


What is an LEV system?

A Local Exhaust Ventilation (LEV) system is used to control or capture airborne hazardous substances and convey them to a point where it is discharged into the atmosphere or safely removed from the system.

The extracted air is usually cleaned and then discharged to the atmosphere or returned elsewhere in the workplace.

What do you have to do?

The COSHH Regulations 2002 state that the exposure of employees to substances hazardous to health be either prevented or, where that is not reasonably practical, adequately controlled. In the majority of cases this is achieved by installing an LEV system.

The Regulations also state that your system must be maintained in an efficient state, in efficient working order and in good repair and that it must be examined and tested at least once every 14 months and in some cases far more frequently.

It is estimated that 60% of businesses are breaking the law because they don’t have their systems tested.

It is also the duty of the employer to keep a suitable record of the examination for a period of at least 5 years. This record should also include details of repairs carried out as a result of the examination and test.

How can we help?

We offer a range of services related to LEV, including the design of a system, maintenance of the system and of course thorough examination and testing.

What’s involved?

Many organisations have LEV systems that are not working effectively.

The Thorough Examination & Testing (TEAT) is defined as careful, methodical, painstaking and complete. It involves many aspects including qualitative and quantitative testing, internal and external examination plus assessment and detailed report . We use the most up to date instrumentation, with minimum disruption to your operations.

Our service exceeds the requirements of the latest HSE guidance (HSG258).

The results of a thorough examination and test allows our engineers to determine the efficiency of your system.

Our report not only contains the results of the test but will also include recommended modifications to improve performance. Our engineers are able to use their years of experience to identify any physical design flaws, defects and maintenance issues that might affect performance.

Repeat testing

You will automatically be added to our comprehensive database and we will remind you when it is time for a re-test, giving you peace of mind that your legal obligations are being met.

In depth sampling

If you require a more in depth LEV test to include Personal Air Sampling (PAS) and/or Background Air Quality Sampling (BAQS) then this is easily arranged and can either be carried out as part of the LEV testing or as a standalone service.
