I use Midwest Mechanical and Life Safety Services to conduct our yearly air change and room pressure differential testing. They do a great job for us every year. Any problems found are brought to my attention. After that the problems are repaired and my report always arrives in a timely matter. I highly recommend their services to any one.

Case Study

Problem Statement:

A Hospital in Southern IL got sited for their decontamination room being positive to the clean sterile room during a JACHO inspection.


Conducted an assessment of the exhaust system that provided the exhaust air for the decontamination room. Determined that exhaust air volume in the decontamination room was very low. Discovered exhaust fan was running in the wrong direction. Maintanance department had replaced motor in the past, but did not check fan rotation. A simple switching of wiring got the fan spinning correctly and the exhaust air to decontamination room back to design flow.


The decontamination room went negative to the clean sterile room like it should be. Hospital did not get an official write up for incorrect air flow because the problem was corrected within 24 hours!
