Indoor Air Quality Monitoring / Surveys and Investigations

Poor air quality within the internal environment may be attributable to a number of different sources. These can include materials within the building such as fixtures, fittings and cleaning products, as well as emissions from specific activities in the case of industrial installations. In addition, high internal pollution levels may be caused by inadequate ventilation or ingress of airborne substances from the external environment. These sources may act individually or collectively to cause a deterioration in air quality.

If poor indoor air quality is suspected, it is recommended that a specialist Air Quality Consultant is appointed in order to investigate potential contaminant sources and identify suitable measures to reduce exposure levels to an acceptable level. KEM has extensive experience of investigative and diagnostic works and we provide a range of services that can be tailored in order to resolve a site-specific issue.

In some cases poor air quality could lead to fatalities

Assessments of the Occupied Air Space
Inspections identify critical environmental issues within the workplace, which can increase productivity, reduce sickness and absenteeism (so-called ‘Sick Building Syndrome’).

Findings include Temperature Analysis, Relative Humidity (RH), Carbon Dioxide, Airborne Particles, (Respirable and Non-Respirable Dust), Airborne Bacteria and Mould/Fungal Spores, and visual inspection of the occupied workspace reviewing all aspects of air quality including capability and limitation.

Carbon Dioxide
Unusually high carbon dioxide levels may cause drowsiness and headaches and reduced productivity of occupants.

Bacteria / Moulds
The primary hazard of mould in indoor air quality is the triggering of asthmatic attacks in susceptible persons. The monitoring of humidity levels will inhibit the likelihood of mould / fungal spores growth.
