NC-v4 EQc1:Enhanced indoor air quality strategies

Enhanced IAQ Strategies - Hazardous Gases/Chemicals

Option 1, Enhanced IAQ Strategies, paragraph B states spaces are to be exhausted where hazardous gases or chemicals may be present or used. What is definition of hazardous gases or chemicals? Two options are available, Options 1 and 2. Can a project achieve Option 2 only without pursuing Option 1?

As far as I know, the GBCI has not defined hazardous gases or chemicals and leaves this up to the design team to identify with the owner. It tends to be the gray areas that cause the most grief. One source you can use is OSHA. https://www.osha.gov/SLTC/hazardoustoxicsubstances/index.html If the project is in California, you can use the Prop 65 list for carcinogens. Or you can try posting the specific chemical here and see what people think.
