COSHH LEV Thorough Examination and Testing

As with any engineering control incorporating mechanical components the system is subject to “wear and tear” and needs to be regularly tested to ensure adequate levels of performance are maintained.  

The legal requirement to regularly test is thus enshrined in the Control of Substances to Health (COSHH) 2002 Regulation 9(2); an employer shall ensure that a thorough examination and test of the local exhaust ventilation plant is carried out at least once every 14 month (or more frequently depending upon process).

Testing data is compared back to the original initial appraisal results, together with previous years data in order to identify any deterioration in system performance.

We utilise the latest measuring instruments, regularly calibrated, i.e.

  • Digital manometers, with Pitot Tube
  • Air Velocity HotWire anemometer
  • Vane anemometers
  • Real time dust (dustrak) and VOC (PID) monitor, together with various personal sampling equipment, impingers etc
  • Draeger Air Flow-check, smoke tubes and high powered torches / dust-lamps

We provide detailed reports including:

  • Changes in operational work practices or substances being used.
  • Design improvements / recommendations
  • System diagrams
  • Stack / discharge effectiveness and environmental impact
  • Full test results stating changes from initial appraisal and reasons for differences.
  • We will carry out simple remedial works where safe and competent to do so, this can often negate the need of a return visit, saving our customers money. This can include such items as:
    • Correcting fan direction,
    • Adjusting air flow dampers
    • Checking for blockages in filters / duct-work systems

Our services also cover ATEX fume and dust extraction systems with additional testing including items such as, but not limited to:

  • Checking for appropriate type of filter media such as conductive / antistatic etc
  • Filter media conductivity tests
  • Ducting and equipment earth bonding checks to CLC-TR_504042003, Electrostatics - Code of practice for the avoidance of hazards due to static electricity.
  • Checking air flows with respect to hazardous area classification; ensuring zoning classification is maintained.
  • Checking air flow alarm system operation and calibration as required.
  • Checking fan and electrical equipment for correct zoning, category and equipment protection.
  • Checking for potential ignition sources

In addition we can also comment on noise at work and ATEX / DSEAR issues and regulations etc.
