Oh my, this must be one of the worst ventilation system I have ever seen. Sealed air intake point, think up to 90% of the air is recirculated; no filters of any sorts, no wonder people are suffering. Hopefully I can get the nod to go ahead with the test. I would like to find out the carbon dioxide concentration in the room to prove my suspicion. Hopefully, it will be above 1000ppm...*oops* I think the Operation Manager thinks I am a consultant.... haha, I don't dare to tell him that I am in fact... a student~ That, I think will most likely freak him out~
.
Oh by the way, please help me to do a little poll please?? --> Thanks in advance~
