What is LEV Testing?

LEV testing through thorough examination is a legal requirement under the HSG258 and COSHH regulations that must be carried out every 14 months or less to ensure compliance.

It applies to all types of local exhaust ventilation (LEV) systems and it covers all elements of the system, including flexible ducts, hoods, LEV monitors, pressure relief integrated systems, illuminators and airflow indicators. During an LEV service, our engineers will check the:

  • Volume flow rates
  • Static pressures
  • Fan speed, motor speed and electrical power consumption

In some cases the inspection will also look at:

  • Replacement or make-up air supply
  • Air temperature
  • Filter performance

Our LEV Service : What's included?

Our fully-qualified safety engineers ensure your LEV system is fit for purpose and compliant with all LEV regulations by performing an inspection that tests all the key elements below:

  • Thorough Visual Examination: We perform a visual inspection to confirm whether all elements of the system are clean, functional and in working order, as well as to identify any urgent repairs needed
  • Technical Performance Assessment: We observe and examine the technical performance of the system to assess whether it works to the standard it was intended to
  • LEV Report: We produce a detailed report of the LEV test and its findings

What is included in the LEV test?

A complete LEV test includes a thorough examination of all components of the local exhaust ventilation system, including hoods, filters and ducts. It also incorporates a review of the system’s technical performance to ensure your equipment is fit for purpose and safe to use.

Who can perform LEV testing?

LEV testing must be performed by a competent person to achieve regulatory compliance.

How often should these tests be carried out?

According to the COSHH Regulations(9.2), LEV systems must be thoroughly examined at least once every 14 months. However, in some circumstances, a higher frequency is required and this timeframe is shortened to 6 months or even 1 month.

Why is it important to conduct LEV tests?

You are legally obliged to perform LEV tests, so you must do so at least every 14 months to ensure compliance with the Health and Safety at Work Act 1974. This is done to ensure occupational safety at your workplace. In addition to this, evidence of LEV testing, including your LEV reports, are required for insurance purposes.

What should be included in the LEV report?

According to the HSG258, all LEV reports should cover the following:

  • The responsible person’s (in most cases, this is the employer) name and address
  • The LEV examiner’s name, address and job title
  • The LEV examiner’s signature
  • The LEV examination and test date
  • Details about the LEV (location, process, substance)
  • Define whether there are normal or special conditions at the time of the LEV test
  • Diagram depicting the layout of the LEV, as well as the test points
  • Information about the condition of the LEV system (hood serial numbers, photos, etc)
  • The intended operating performance and whether it is currently achieved
  • Information about the methods used to assess the technical performance of the LEV system
  • Air sampling results relevant to the LEV test
  • Notes on how the LEV system operators use the system
  • Wear and tear, plus any possible part replacements identified
  • Any minor adjustments or repairs carried out
