The HSE has recently launched a new webpage looking at the importance of properly commissioning LEV (local exhaust ventilation) systems. 

The page includes information on:

• why LEV systems need commissioning
• what details the commissioning report should include
• what operators should do before they start using the LEV
• core elements of commissioning
• the condition of the LEV system
• commissioning results
• what the law says
• HSG258 – further guidance on LEV systems

What is commissioning?

Commissioning sets the benchmark for future LEV tests (thorough examination and testing: TExTs). It documents the performance requirements for the LEV system to ensure employees are protected from exposure to hazardous airborne substances - the details can then be used as a reference point for all routine LEV tests.

What should a commissioning report contain?

Commissioning reports should contain basic information including the date of the test, the duty holder’s name and address, and the commissioner’s name, job title and employer. They should also record vital details such as the location and ID of the LEV system, the hazardous substance it is being used to control, the application it is being used on, airflow rates, pressures and much more.

Why is this information important?

Regular LEV tests undertaken by a competent person are a legal requirement under COSHH (Control of Substances Hazardous to Health) Regulations. During this test, the LEV engineer should check that the LEV system is performing as intended to confirm that employers are compliant with COSHH, and no harmful substances are escaping into the air. The commissioning report provides the information required to check that this is the case. If the LEV engineer does not know the required airflow, or what the system was originally installed to control, it makes it difficult to accurately assess if the LEV system is still fit for purpose.

Filtermist’s commissioning reports

Filtermist employs dedicated teams of competent installation engineers that install and commission extraction systems used to effectively control oil mist, dust, fume and smoke. Following the installation of a new extraction system, or the relocation of an existing system, the engineer undertakes a series of tests and then enters the findings into the commissioning report template on their digital tablet.

The template has been designed following HSG258 guidance on the details that should be included in the commissioning report. This report is then emailed to the customer, and a copy is kept on the customer’s file so it can easily be retrieved if needed.
