Here's just a small sampling of some commercial inspections we have done recently.
It's not uncommon for workplace-based health complaints to necessitate air quality testing and inspections. We carefully scope the buildings and HVAC systems, sample for appropriate contaminants and submit comprehensive reports listing findings and recommendations.
In one case the bank staff could not work in parts of the building following air duct cleaning. Headaches, rashes, eye irritation and coughing were the chief complaints. We found a potent duct lining "paint" had been used which spread fumes throughout the system and building.
Another bank had very old HVAC systems and ducting that we found to be highly contaminated with molds.
Yet another bank had serious water damage from surface water intrusion during a storm. While on site we also found toxic molds in the ceiling cavity from dripping HVAC lines.
There are numerous air quality issues to consider in medical complexes. We have found odor sources from IV bag disposal, poor air circulation in prep rooms, cleaning chemical sensitivities and high Carbon Dioxide from dry ice storage. Infection control, air and surface sanitization and adequate ventilation are important as well as overall odor control. These are challenges in even the newest facilities.
Manufacturing and Warehousing
The multiple challenges with large facilities often include alternative air conditioning systems. Large warehouses sometimes have nothing more than ventilation fans. Our humid climate zone can wreak havoc with textiles and natural materials. One shoe distribution company had issues with boxed shoes growing surface molds. Another warehouse had bolts of fabrics growing molds.
Evaporative coolers for alternative air conditioning can be reservoirs of biological contaminants. We have found them to be contaminated with Legionella and other bacteria and molds.
