Air Quality Monitoring & Assessment
Air Quality Testing
We are expert at providing real time measurement of carbon monoxide, sulphur dioxide, ozone and oxides of nitrogen at parts per billion levels.
Our instruments have a self-logging facility to record concentrations of the pollutants over a pre-set averaging time, together with several ‘diagnostic’ parameters. Monitoring for PM10 fine particulates is also possible, using real-time or pumped filter systems, together with volatile organic compounds (including benzene).
As well as short term monitoring, our instruments can be used to monitor air quality over longer periods to take into account fluctuations in meteorological conditions.
Expert Interpretation
Data recorded by the instrumentation is downloaded and interpreted against current standards, legislation and guidance by Lab Works EA’s environmental scientists. Fully comprehensive reports are issued, together with weather data from the Meteorological Office over the monitoring period.
Typical Applications Include
To assess air quality for local authorities in accordance with the Kenya’s Air Quality Regulation
To measure air quality around an industrial site as a requirement of a ISO 14001 Environmental Management System or IPPC Permit
For assisting land developers with planning applications and environmental impact assessments
The effects of air pollution on health have been recognised for over three centuries. Current national legislation is now focusing on maintaining or improving local air quality to protect public health. NEMA’s air quality regulation has set targets or limit values for individual pollutants, with action plans drawn up for those areas where there is a risk that standards are or might be exceeded.

Lab Works EA’s occupational hygienists are trained and experienced in all aspects of LEV (Local Exhaust Ventilation) assessments.
Exposure to hazardous substances in the workplace should either be prevented or adequately controlled.
The object of an LEV system is to control the emission of such substances to the atmosphere as close as possible to the point of source, thereby preventing release into the workplace. To be effective, LEV must initially be well designed and constructed. Over time, the performance of systems can deteriorate due to wear, blockage or damage. Thus, regular inspection and testing is critical to ensure that control of exposure remains adequate.
Legal Background
The DOSH and air regulations require employers to assess and control the exposure of their workforce to hazardous materials. DOSH and air regulations requires that where local extract exhaust ventilation plant is used to control exposure to substances hazardous to health, a thorough examination and test be undertaken at least once every 14 months to ensure that it remains in good working order, or more frequently in some specific cases.
HSE Guidelines
Local Exhaust Ventilations Systems should be examined and checked. The aim is to ensure that LEV systems which are intended to control substances hazardous to health, including biological agents, continue to operate as originally intended. In order to work a system should effectively capture released hazardous substances, remove them from the workplace and safely dispose of them. The health of people indoors and outside is then protected.
LEV Monitoring Techniques
Lab Works EA’s employ a number of techniques to check LEV systems. This will include flow checks using specialist anemometers, pitot tubes and smoke tests, pressure measurements and visual examinations. The ductwork in larger systems will need to be fitted with access points for the equipment. If these are not already in place, Lab Works EA’s staff can install them where it is possible to do so safely.
Exposure Monitoring of Staff
HSE guidance also suggests that staff who are protected by the LEV may also need monitoring to confirm the effectiveness of the system at controlling exposure to a substance hazardous to health. Lab Works EA’s Occupational Hygienists can monitor individual staff members and the general atmosphere for most hazardous materials.
Emissions to Atmosphere
For some processes there may be regulations requiring the monitoring of the final exhaust from the system into the environment. Lab Works EA’s has specialist accredited staff who can undertake this work and provide reports to provide reassurance to the enforcing authorities. Helping you meet COSHH regulations Local exhaust ventilation (LEV) systems are commonly used as an engineering control measure to capture and transport harmful substances released from a process at source, before entering the workplace atmosphere.
The DOSH Regulations 2007 places a duty on the operator to ensure that all control systems, including LEV, are tested by a competent person and inspected at least once every 12 months, or more frequently for some processes.
Under the DOSH Controlling airborne contaminants at work, it is the employer’s responsibility to know and understand the following:
The parts of an LEV system and their function.
How the LEV system should be used.
How to recognise a damaged part.
Simple checks that the LEV system is delivering its design performance and is effectively controlling emissions and exposure.
Exova can conduct a thorough and comprehensive examination of your LEV system to determine its effectiveness and evaluate the system in accordance with recommended criteria, i.e. capture velocities, duct velocities.
Telling You What You Need to Know
Employers need to be aware of the following:
The parts of an LEV system and their function.
The legal requirements for the thorough examination and testing of LEV systems.
How to recognise a damaged part from a visual inspection.
The purpose of, and how to use, the measuring and assessment instruments and techniques.
The most suitable instrument to test the performance of each part of the LEV system.
The standard to which each part of the LEV system should perform.
How to recognise when a part of the LEV is performing unsatisfactorily, based on the measurements taken and assessment methods used.
How to assess whether the LEV is effectively reducing airborne contaminant emission and operator exposure.
How to collate and record information in a clear, concise and useable way.
How to work safely with the LEV plant and the hazards associated with it.
The technical report produced will subjectively assess the control measure, and provide detailed comment and practical recommendations, where appropriate.
