COSHH Testing

At Auto Extract Systems, we offer COSHH testing services that can be tailored to your business’ requirements to ensure that any local exhaust ventilation (LEV) system complies with Control of Substances Hazardous to Health (COSHH) Act (2002). Whilst maintaining a team of dedicated inspection engineers who are specifically trained to COSHH test and service any specialist extraction system, we offer first-class customer service and support at every stage.

In addition, we are capable of undertaking COSHH tests, or necessary work on LEV equipment, irrespective whether it was supplied by us (Auto Extract Systems), or on any* other extraction equipment of a similar nature, irrespective of its origin. (*Subject to acceptance by Auto Extract Systems).

Local exhaust ventilation (LEV) plant tests must be performed at least once every 12 to 14 months (this period is reduced to every 6 months where metallic specks of dust are being controlled).

Our in-house software enables you to access all your plant’s COSHH test certifications in one convenient place through our secure portal. Our support team will also contact you to notify when any LEV extraction equipment is due it’s retest and service and are on-hand to facilitate booking an inspection engineer to visit, when convenient.

The legislation

The HSE state that any: “Local exhaust ventilation (LEV) should collect or contain the airborne contaminants and carry it away from workers for treatment and/or discharge to a safe place, ensuring adequate control to reduce the exposure to staff that can lead to ill health.” For good practice for checking, maintaining and testing local exhaust ventilation (LEV) equipment to control gas, vapour, fume or dust caused by your business’ operational processes.

The Control of Substances Hazardous to Health (COSHH) (2002) Act states:

  • Regulation 6 of the COSHH act requires you to carry out risk assessments and ACT on the findings. Try an eliminate risks by changing the process, product or concentrations.
  • Regulation 7 of the COSHH act requires you to consider a Hierarchy of Control measures to ensure that exposure to substances hazardous to health is adequately controlled appropriately to the health risk. Minimise exposures using engineered methods and check and review regularly.
  • Regulation 8 of the COSHH act requires you to make sure controls are in place and implemented and any defects are reported and acted upon.
  • Regulation 9 of the COSHH act requires that any control measure taken to comply with regulation 7 must be maintained in an efficient state, in efficient working order and in good repair. LEV systems should be examined and tested at least once every 12-14 months (in most cases). However, it is common practice to have systems tested and maintained annually.

Records must be kept on file for 5 years for presentation if required. A logbook and manual must also be on hand if requested.

What’s included in a COSHH test?

Each COSHH test and inspection include the setting up of a LEV record for each item of plant. Each record will contain all the necessary information required to comply with the regulation, which includes:

  • Name and address of employer responsible for plant
  • Identification and location of LEV plant, process and hazardous substance controlled
  • Date of last thorough examination and test
  • Conditions at time of test
  • Intended operating performance. Current performance. Repairs required to achieve intended performance
  • Test methods employed
  • Date of the examination and test
  • Name, designation and employer of testing officer
  • Authentication by testing officer
  • Details of repairs carried out.

Testing filtration extraction systems

We advise that if a system has a filtration system, that the existing filters are cleaned prior to the test to maintain the highest possible airflows at the extraction source.

Test failure

In the event of a system test failure, (by not meeting the benchmarked required) our engineers will notify the site manager. A quotation will be issued to restore the extraction equipment back to within the COSHH regulations and the site manager is expected to act on the test’s findings.

COSHH testing terminology

The capture velocity is the air velocity around a source to capture the contaminant cloud and draw it into the hood.

The transport velocity is the air velocity in a duct to convey the contaminant from the source to the filter or atmosphere and also to prevent deposition in ducts.

A breathing zone is a region around operators from which they draw air for breathing. Commonly defined as being within 300mm of the workstation operator’s nose/mouth.
