Benefits of servicing your LEV system

You must, by law, get your Local Exhaust Ventilation (LEV) system thoroughly examined and tested by a competent LEV engineer at least once every 14 months (dependent on the process).

But regular servicing is also essential to keep your LEV systems in good working order. LEV systems are designed to remove harmful substances, such as dust, fumes, and vapours, from the working environment, thus safeguarding the health and well-being of employees and ensuring compliance with health and safety regulations. If these systems are not kept in proper working order, this can pose risks to your workforce and productivity.

Why is LEV Servicing Important?

Workforce Safety & Productivity

If you have an LEV system on your premises, then you are likely to have an understanding of its importance to the health and safety of your employees. Not keeping up with routine LEV servicing can make your system less efficient and jeopardise the health of those on your premises.

The cost of running an LEV system is likely to offer good value by comparison to not only the days missed off work, but also potential legal fees if your business is seen to not be taking the necessary precautions to protect the workforce.

A healthy workforce also means higher productivity. According to HSE figures, 31.5 million working days were lost due to work-related ill health in 2022/23.

Less Down Time For Your LEV System

Regular servicing from an expert LEV engineer can highlight potential issues early. This lowers the risk of expensive downtime during which manufacturing, and production processes cannot continue.

Increased Efficiency

If your filters and ductwork become blocked, they will become less efficient. This can be easily spotted during a regular LEV service and rectified before it becomes an issue.

More Likely to Pass a Thorough Examination and Test (TExT)

You must, by law, get your LEV system thoroughly examined and tested at least once every 14 months (dependent on the process). A system that has been properly maintained with a recommended quarterly servicing programme is far more likely to be in good working condition when it undergoes its mandatory TExT.

Continued Warranty & Insurance Cover

If your system is not serviced regularly, your warranty will be invalidated. There is now also a strong suggestion that your insurance company may not cover you if you are found to be in material breach of the law. More information about this can be found in COSHH Regulation 9.

Our advice is that LEV servicing is undertaken on a quarterly basis. In addition, visual and qualitative checks should be carried out in between. We can provide BOHS approved training to your team so they can be confident to carry out these regular checks and report anything that doesn’t look right.

What Checks Should be Carried Out During LEV Servicing?

Many companies offer LEV servicing, but not all LEV services are the same. We have put together a list of the main checks that a competent LEV servicing engineer would be expected to carry out when it comes to your regular LEV service.

Visual checks

During a service visit, a competent service engineer will inspect your system for any visual damage. This will include dents, tears and leaks. In addition, all the fixings should be checked – from the inlet to the discharge. 

Component checks

A competent LEV servicing engineer will also check the components of the system. They will ensure everything is working efficiently and effectively as originally logged in the commissioning documents. They will consider whether any components need changing or cleaning imminently. This will include filter efficiency checks and examinations of the system components.

Should the report recommend new parts or system cleaning, then the work can be scheduled and completed by one of our expert engineers when it is convenient for you, thus reducing any inconvenience. This will prevent unexpected breakdowns which can be expensive and potentially lead to production downtime.


Ducting checks

Ducting will be inspected to ensure there are no blockages affecting the way your system runs. This is not only a safety risk due to the reduced efficiency of your LEV system, but the build-up of materials such as flour dust, wood dust, rubber or diesel soot could also result in a fire. The build-up of heavier materials like metals released from grinding could lead to the duct collapsing.

As well as these sudden, drastic consequences of blockages, there are longer term issues too. Blockages can create additional resistance in the system that leads to mechanical failure over time and consequent repair bills. An example of this is if a fan has to work harder to ensure the necessary airflow. Not only will this result in higher energy consumption and electricity bills, but it will also mean the fan is more likely to fail and require replacement.

High Level Cleaning

Ducting checks during a routine LEV service may highlight the need for high level cleaning.

When high-level surfaces and ducts are left to build up dust and other dirt it can present a number of problems for a building and its occupants. These could include a reduction in air quality and heightened fire risk, as well as contributing to general uncleanliness and poor presentation of your premises. In areas where food is prepared, hygiene standards could be driven unacceptably low.

Furthermore, some insurance companies will not authorise damage payments from fires caused by infrequent duct cleaning. This makes the need for regular duct cleaning even more vital for many businesses.

High level cleaning requires extra health and safety considerations and specialist equipment when compared to more routine cleaning. It is important to apportion some budget annually for the cleaning of high-level surfaces and ducts.

Every job will be different but we will provide you with a competitive quote based upon your work environment, considering, for example, the substances you work with, inspection hatches and general accessibility. If you have high-level surfaces or ducts that need professional cleaning, then contact our friendly team for help today.
