Mold testing accuracy is extremely important, but just as important is quality control. Accuracy involves collecting samples in a precise and methodical manner while quality control is about keeping excellent records of the testing to avoid mistakes.
When we started our mold assessment company, we developed standards and operational protocols for the office and in the field. Besides a mold testing methodology to ensure accuracy, we developed a quality control system to maintain a visual record of the mold testing in the field, because we felt that a record of the chain of custody was insufficient.
Pictures provide a visual record of the testing and
complement mold testing accuracy.
We take a digital photograph of a placard with the following data for each sample:
- For each spore trap we collect, we write the above information on a small placard and take several wide angle pictures to show the placement of the air pump in relation to the room, then a close-up picture of the spore trap showing the spore trap number with the placard behind it. The pictures are taken while the air pump is operating. Thus, the process is quick. We also use a placard when collecting a surface or bulk sample. Our quality control has been invaluable for lawyers who demand accuracy and proof to win their case. Our clients appreciate the care we take in mold testing and they also like to see these pictures in their reports.
Quality control helps prevent mold assessors
making errors between samples.
We strongly recommend mold assessment companies to practice quality control in mold testing. Like us, mold assessors will gain peace of mind, and ultimately clients will be better served.
