Baseline IAQ Surveys

Baseline IAQ assessments are used to determine the state of the air quality in a particular indoor environment where IAQ monitoring has not been completed or has not been completed recently.

Indicator measurements of building performance can be assessed to determine if a building is performing poorly. Important indicator measurements may include:

Norpro H&S is able to conduct a management system gap analysis for organizations looking to meet any of the standards below:

• Air and Surface Temperature
• Relative Humidity
• Carbon Dioxide (CO2) measurements as a means of checking adequacy of ventilation
• Surface Moisture
• Particulate Matter
• Total Volatile Organic Compounds (TVOC)
• Carbon Monoxide to check for leakage of combustion devices within the building.

Following the completion of an assessment, a report will be issued including assessment results and recommendations for IAQ improvement if required.

Mould Assessment and Testing

Mould belongs to the kingdom fungi (along with mushrooms and yeasts) and have very specific temperature, nutrient and moisture requirements for growth. Indoor mould growth is typically associated with high humidity, dust, moisture levels and water damage or intrusion. Certain mould can cause adverse health effects; including hypersensitivity diseases (allergies), infectious diseases, toxic effects, and irritation of the respiratory tract. Often, occupants of homes are suffering from numerous symptoms commonly associated with or caused by indoor mold growth.

Mould assessments should always include a visual inspection of the indoor area of concern as well as gathering information regarding the building history, current or previous moisture issues, understanding air flow patterns, and an inspection of the windows and HVAC systems. The outdoor environment should also be inspected by assessing outdoor siding, flashing and eavestrough systems.

Air Sampling

If a visual inspection does not identify mould, but there you have reason to believe that there may be inconspicuous mould growth present within a building, air testing for Mould may be completed. Non-viable (total spore count) air sampling is completed using specific sample media for the rapid collection and analysis of mould spores. This analysis involves spore counting and identification of different categories of mold spores within the area of concern versus identified control environments (outdoor environment, or indoor areas with no confirmed concerns) to determine if there is an indoor mould growth source.
