COVID-19 Indoor Air Quality Testing

COVID-19 air testing can be performed in addition to surface contamination testing.  We recommend testing the air (for COVID-19) in addition to surface decontamination where employees or patrons of an establishment test positive for COVID-19.

Returning to work during COVID-19 can be a stressful experience. Many people are expressing concern with airborne virus droplets and having sufficient clean air. Additionally, sanitizing products can contain harsh and noxious chemicals known to irritate building occupants. We have listed some common sampling and analytical parameters for IAQ sampling and testing during the pandemic. If you have concerns, please get in touch with us.

ParameterPossible Indicator/SourceRelated Complaints
SARS-CoV-2The virus responsible for causing the respiratory illness known as COVID-19 may be present if occupants have been in contact with exposed persons or travelled to areas with known cases. These tests are designed to positively identify the presence of the virus in air or on surfaces.Symptoms may include fever, dry cough, fatigue, as well as a variety of other symptoms.
Thermal comfort parameters (relative humidity & temperature)Improper placement of thermostats, poor humidity control, inability of the building to compensate for climate extremes, tenant-added office equipment and processes. Ineffective HVAC system.Too hot/cold, dryness
Carbon dioxide (CO2)People/occupants
Ineffective HVAC system.
Headaches, tiredness, stuffiness
Carbon monoxide (CO)Incomplete combustion; faulty gas/oil appliances (i.e. furnaces, boilers, water heaters, stoves, refrigerators), tobacco smoke; infiltration of ambient air containing CO from parking garages or ventilation intakes too close to vehicle activityHeadaches, dizziness, weakness, nausea, visual disturbances and confusion. Prolonged exposure can cause coma and death
Respirable Suspended Particulates (RSP)Ineffective HVAC system. Smoke, air inlets, paper, duct insulation, water residue, carpets, HVAC filters, poor housekeeping.Eyes, ears, nose and throat irritation, allergy symptoms
Total Volatile Organic Compounds (TVOCs)TVOCs refer collectively to a large number of volatile organic compounds that are based on a skeleton of carbon atoms. VOCs are emitted from a variety of sources including: building materials, cleaners and general office materials, copying and printing machines, laser printers, toners, computers, carpets, smoke, paints, inks, adhesives, perfumes, hairsprays, solvents.Mild acute reactions, headache, allergy symptoms, dizziness, fatigue, odours
FormaldehydeCarpets, particleboard, furniture, and fabrics often contain cleaning fluids or adhesives.Eye irritation, sore throats, nosebleeds, headaches, fatigue, nausea, dizziness, breathlessness; skin rashes
Molds & BacteriaStagnant water in HVAC system, wet and damp materials, humidifiers, air conditioners, condensate drain pans, and water towers.
Odours, visible molds usually as a result of water infiltration that was not dried within 48 hrs. Mold thrives in ideal climates above 25ºC and above 60% relative humidity and can sustain growth on numerous sources of organic materials including drywall, carpets, wood, and any other cellulose material.
Eyes, nose, and throat irritation, allergy symptoms
