Question #
I2.4 – CO Monitoring in Parking Areas
Question
Do carbon monoxide (CO) concentrations in enclosed parking garages and loading docks 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 internal combustion vehicles can present a serious health and safety risk. Monitoring carbon monoxide within enclosed parking areas and loading docks can help identify exposures before they exceed current occupational exposure limits.
The current ACGIH Threshold Limit Values for carbon monoxide exposure is 25 ppm.
Requirements
-
- If IAQ testing data is available, provide representative sampling that:
- Demonstrates that CO levels are below 25 ppm
- Is conducted at least annually and captures high traffic periods
- If sensors are installed:
- Demonstrate that concentrations of carbon monoxide are 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 25 ppm. Provide sensor logs and/or IAQ testing data for these locations
- If IAQ testing data is available, provide representative sampling that:
