LEV Testing

At Impact Technical Services, we conduct LEV testing and all related services to businesses across all sectors, throughout the UK. Our LEV technicians are qualified to BOHS P601, P602 & P604 and have unrivalled experience and knowledge of all aspects of LEV testing, LEV system design, installation and commissioning to ensure you receive the very best service.

LEV testing is a legal requirement to ensure employees are protected from hazardous airborne substances such as welding fume, wood dust, oil mist and much more. A local exhaust ventilation system, or LEV system, is the best way to ensure these substances are removed from the working environment. LEV testing is inexpensive and provides peace of mind for both the employer and employees.

See our 10 reasons why you need LEV testing here.

What is LEV testing?

LEV testing is a thorough examination and test (TExT) of your LEV (local exhaust ventilation) equipment, to ensure it’s working effectively and efficiently. The LEV test includes checking the condition of the ducts, hoods and filters along with the measurement of the technical performance and an assessment of the working condition of the LEV system.

All examinations will be carried out in compliance with HSE regulations and we will advise you of the recommendations to be made, should your LEV system not meet the standards required.


Why do you need LEV testing?

LEV testing is a legal requirement and regulation 9 of the COSHH regulations state that LEV systems must be monitored and maintained to ensure they are in good working order.

LEV testing is relatively low cost and extremely necessary where workers are exposed to hazardous substances such as welding fume, wood dust, flour dust and spray paint fume, for example.

It is important that you are following the correct procedures in protecting your staff according to HSE guidelines. The HSE will advise any company not adhering to the guidelines and if this is not corrected, a fine will be presented. The HSE make regular random visits to workplaces across the UK every day to check workers are protected.


Your responsibilities as an employer:

So you have your LEV system in place and your staff are protected, great. How do you keep it that way?

It is a legal requirements for employers to ensure LEV systems have LEV testing also known as a ‘thorough examination and test’ (TExT) at least once every 14 months in order to comply with Regulation 9 of the COSHH Regulations.

Employers must also ensure that LEV equipment is maintained in an efficient state, in efficient working order and in good repair.

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 (TExT).

In order to assist you with the above, we can provide you with the following services:

  • LEV Testing – Thorough examination and testing (TExT)
  • LEV system maintenance
  • LEV system design and installation

How we can help: LEV services

We will carry out a thorough examination and test (TExT) in compliance with COSHH Regulation 9 as detailed in HSE Guide HSG258 “Controlling airborne contaminants at work – a guide to LEV”.

Our levels of service vary according to your requirements and each visit can be tailored to your individual needs. Some clients choose to combine the annual servicing of their extraction/ventilation system with the LEV testing.

This proves to be very cost effective and also gives you peace of mind knowing that your complete system is being tested and maintained by the UK’s market leader in extraction/ventilation systems.

Airflow indicators

Airflow indicators are a simple yet effective way of instantly monitoring the airflow of your LEV system. An airflow indicator can be fitted to your systems’ ducting and will provide a visual cue if the system is operating correctly and also if it is not (see image below).

LEV testing
All Local Exhaust Ventilation (LEV) systems must have a thorough examination and test (TExT) at least once every 14 months, so if your system is due a test, please get in touch to arrange this asap.

The HSE has recently updated its guidelines with regards to LEV Testing – Thorough Examination & Testing (TExT) during the pandemic:

  • Businesses and inspection bodies must co-operate to ensure access to plant and equipment for TExT schedules to continue
  • If your business is closed, you should still ensure TExT’s are carried out to remain compliant
  • Critical industries will be prioritised, so other sectors may experience a delay with appointments
  • LEV equipment should not be used if a TExT has expired. Equipment must be safe for staff to use and employers must comply with HSE regulations
