Practical Inspection Procedures

8. INDOOR AIR QUALITY TESTING EQUIPMENT

Ensure that air quality monitors meet the resolution, range, and precision required for the desired measurement ranges of both carbon monoxide and nitrogen dioxide.

PURCHASING IAQ TESTING EQUIPMENT

Health Canada recommends using a nitrogen dioxide monitor that is designated as a Federal Reference Method (FRM) or a Federal Equivalent Method (FEM). However, nitrogen dioxide monitors designated as FRM or FEM are significantly more expensive compared to electrochemical gas sensors on the market.

The cost of an FRM or FEM designated sensor may not fit the budget of many public health units or ice arenas. In addition, most electrochemical sensors do not meet the resolution requirement of 0.02 ppm, which impacts recommendations and action levels set by the public health unit.

EQUIPMENT LOAN PROGRAM

Due to budgetary constraints, it may be more sensible for your health unit to borrow indoor air quality testing equipment. For short-term access to monitoring equipment, consider utilizing the Public Health Ontario Equipment Loan Program. Contact EOH@oahpp.ca to book a device. 

Ensure all public health inspectors are trained on the correct operation, storage, calibration, and maintenance of indoor air quality testing equipment.
