Question #

I2.5 – CO Monitoring in Occupied Spaces

Question

Do carbon monoxide (CO) concentrations in occupied spaces adjacent to parking garages, loading docks, and mechanical rooms meet minimum thresholds?

Applicability

Applicable to all buildings (systems or equipment in the owner or landlord’s control)

Answer

Select one of the following:
  • Yes — CO is tested
  • Yes — CO sensors installed
  • No
  • Not Applicable – there are no enclosed parking garages of loading docks at the building

Description

Carbon monoxide emissions from vehicles and improperly vented combustion equipment like boilers and hot water tanks can present a serious health and safety risk. Monitoring carbon monoxide concentrations in occupied spaces adjacent to indoor parking areas and mechanical rooms can help identify exposures before they become a health hazard.

Health Canada has indicated that carbon monoxide concentrations above 5 ppm are indication pf possible emissions and warrant further investigation.

Requirements

    1. Identify occupied spaces that are located adjacent to parking garages, loading docks and mechanical rooms
    2. If IAQ testing data is available, provide representative sampling that:
      • Demonstrates that CO levels are below 5 ppm
      • Is conducted at least annually and captures high traffic periods
    1. If sensors are installed:
      • Demonstrate that concentrations of carbon monoxide is monitored continuously
      • Provide sensor details (electrochemical or metal oxide semi-conductor with a resolution of 0.1 ppm)
      • Show that sensors are calibrated in accordance with manufacturer’s specifications
      • Confirm that CO levels are below 5 ppm

Documentation

    • Identify occupied spaces potentially exposed to CO
