Primary Complaint: Concerned about excess dust from recent demolition project
RELEVANT PROJECT INFO
Employees were in the process of cleaning the carpets during the inspection. The humidity generated by the carpet cleaning machine appears to have elevated the particulate levels in several of the sampling sites.
Resampling of the elevated areas once cleaning had ceased indicated particulate levels were again dropping.
PARTICLE COUNT RESULT
Carpet cleaning was being conducted in most of the common areas of B wing.
Technician took ambient readings in non-affected offices with the door closed to minimize any artificially elevated particle counts.
Classrooms where carpet cleaning was being conducted were marked on the table with an asterix
Elevated particulate readings were confirmed to be directly related to the carpet cleaning activities based on these criteria: Particulate readings in non-affected offices all revealed relatively consistent results. Technician took a particulate reading directly behind the carpet cleaner and is indicated in sample: C-100HS Sample C-100HS was used as a maximum threshold for the elevations the carpet cleaner created. Particulate readings were conducted a second time in several rooms, approximately 10 minutes after carpet cleaning had been completed. Results revealed actively dropping particulate levels.
While the carpet cleaning activities did affect the real-time sampling results, enough data was collected to determine: A) Offices in which cleaning was not conducted were found to be within normal indoor air quality thresholds. B) Areas which were affected by the carpet cleaning also were found to be returning to typical readings shortly after the cleaning process. C) Elevated particulate levels were likely due to aerosolized water vapor as indicated by the higher relative humidity levels taken at the same time.
AIR SAMPLING RESULTS
The total spore count for the rooms B-119, C-114, D wing Shop #2 and D-106 sample(s) registered 1,100, 1,900, 870 and 590 spores per meters cubed respectively.
Individually, the following species were identified in your samples.
Sample 1 | B119
Sample 2 | B114
Smuts, Periconia, Myxomycetes:
Spore trap readings confirm the results of the particulate count based on these critera: No elevated levels of mold spores were present in any of the samples taken. Dust particulate (background debris) was found to be within normal or below normal levels (3+) is a normal reading for an indoor sample.
All spore trap samples appear to be wthin normal levels and do not indicate an area of concern.
Provide fresh air intake in all rooms immediately following any carpet cleaning activities. This will allow elevated relative humidity levels to return to normal and expedite the dry-out of the carpets.
