Concerns over contaminants in the indoor environment are prevalent in today’s world.  Safex has conducted more than 900 indoor environmental quality evaluations for commercial and residential buildings. Evaluations of the indoor environment may include the following

• Visual inspection of affected areas;
• Interview with building occupants;
• Determination of airflow, temperature, humidity, carbon dioxide concentrations;
• Review of the ventilation system;
• Perform a general volatile organic compound (VOC) screen.
• LEED IAQ Certification Air Testing - Formaldehyde, VOC, carbon dioxide,  PM 10, and 4-phenyl cyclohexene 

Contaminants may originate from a variety of sources inside or outside of a building. Airborne chemicals, bacteria, fungi, pollen, and dust may all contribute to the problem. Other sources of contaminants may include smoke, dust, poor maintenance of HVAC systems, cleaning supplies, pesticides and building materials and furnishings.  While any of these may be present in every building, problems may arise when concentrations become excessive.
