Air (A01 - A04) Preconditions Flashcards
What is the acceptable air quality threshold for particulate matter in occupiable spaces? (PM2.5 & PM10)
A01 - Air Quality
a. PM2.5: 15 µg/m3 or lower
b. PM10: 50 µg/m3 or lower

List common air pollutants. What does exposure do to you?
A01 - Air Quality
Volatile Organic Compounds (VOCs) ozone particulate matter carbon monoxide radon
They increase risk of cardiovascular disease, respiratory disease, asthma, and cancer. Common symptoms include headaches, dry throat, eye irritation, and runny nose that may worsen over time.
What is the modified air quality threshold in polluted regions for particulate matter in occupiable spaces? (PM2.5 & PM10)
(for projects where the annual avg. outdoor PM2.5 level is 35 µg/m3 +)
A01 - Air Quality
a. PM2.5: 25 µg/m3 or lower.
b. PM10: 50 µg/m3 or lower. (same as acceptable threshold)

What is the DYNAMIC air quality threshold in polluted regions for particulate matter in occupiable spaces? (PM2.5 & PM10)
(for projects where the annual avg. outdoor PM2.5 level is 35 µg/m3 +)
A01 - Air Quality
a. PM2.5 < than or = to 30% of the 24-hr or 48-hr avg. of outdoor levels.
b. PM10 < than or = to 30% of the 24-hr or 48-hr avg. of outdoor levels.
How do you verify the different types of thresholds for particulate matter?
A01 - Air Quality
a. performance test for acceptable thresholds.
b. technical documents + performance test for modified and dynamic thresholds.
