| Two weeks ago my project team cleaned the carpets in the state senate staff offices using the bonnet system. This was done in the evening, when the facility was unoccupied. The following day we received reports the staff nurse complaining of skin and eye irritation saw that 20-30 people. One occupant visited her personal doctor, whom said she appeared to have suffered some kind of chemical burn. Two week later we are still looking for the source of the mysterious irritant. The day following the incident, I called in a out side carpet cleaning company to extract the carpet using clear water, in hopes to dilute any remaining chemicals. Upon inspection of their work we discovered the carpet splitting at the seams throughout the facility. We've called in an industrial hygienist to hopefully find the problem.
History of the cleaning process:
The carpet cleaning crew has for at least six months, been using a water base carpet cleaning chemical, and water base odor eliminator, to add a fragrance, in all of the 40 facilities we maintain, with no adverse effect.
All of the investigation in the problem area is focused on the cleaning process. The HVAC team checked the air handling systems, and all was in the normal range. The hygienist consultant has requested MSDS on both chemicals used in the cleaning process as a starting point for his investigation. At this point I am mystified. I’d like some feedback from anyone out there having similar experiences, or theories of what the problem maybe, and possible solutions?

| We had an issue with mold last year and had the building remediated and tested. We were given clearance at the end of the summer. One of the problems was our split faced block had never been sealed (new building in 1999), allowing moisture to come in. We had the block sealed last Fall, however, the sealant had a mineral spirit solvent which lead to fumes in the building which have really bothered some employees. We have come to believe the amount of sealant used on the block has lead to an inability for the sealant to dry; i.e., it simply soaked right into the brick and the fumes come through the walls. We corrected the problem by creating positive air pressure, this has helped for the most part, however, there are a few very sensitive employees who still have problems. We don't anticipate the sealant to be completely dried for another few months, thus the fumes will not be dissipated for quite awhile. With the warmer weather, we will be battling the fumes more, I believe. My question is if an air cleaner that specifically controls VOCs would help in this situation. Our main office is an open concept, exposed truss building, so we would need several cleaners. We are concerned about the health of our employee first. |

| I have been searching for IAQ measurements/statistics related to green cleaning vs. standard cleaning.
Also, the direct impact to occupant (health/wellness, increased productivity, reduced health cost issues, etc.) statistics related just to cleaning seems hard to find. There are plenty of statistics for overall IAQ linked to efficient design, construction, HVAC, materials, etc. Green cleaning must have an impact on those figures...but how much? |
