FAQs about IEQp2 :

Our outside smoking area is located less than 25 feet from an emergency exit. Is this okay since that door is rarely (if ever) used?

EBOM-2009 IEQp2:Environmental Tobacco Smoke (ETS) Control

Differential Pressure Measurement

Hello, has anyone experience in conducting the differential air pressure measurement of a smoking room with respect to each adjacent vertial chase? This requirement seems very difficult to meet. Is it required to test each cabel or service duct that is adjacent? Or is it required to conduct additionally a blower door test to verify proper sealed chases? Thank you very much

Good question, we are dealing with the same problem. Does anyone know something about testing vertical chases and if cabel channels or service ducts can be excluded, if openings are not accessable? Thanks

In our experience, it has been sufficient to conduct differential pressure testing for spaces that share an opening with the smoking room. It may help your cause to also provide a description of the conditions/construction of the room that ensures that smoke doesn't migrate to other spaces. We have not been required to address cable channels or service ducts.
