Scenario: A container of Xylene is broken and 12 cm3 of this material is evaporated into the air in a room with safety factor of 1.5 during 3 hours. How do I calculate the airflow for diluting the contamination to 30% of the OSHA PEL?


Given Info:

specific gravity=0.88

molecular Weight=106 @(100%)=100

OSHA PEL 100ppm (@30%)= 30 ppm


If the room is 30x30x10 ft3. How can I calculate the effective ventilation airflow and effective air exchange rate?
