An Industrial Hygienist is often called in to test the indoor air quality of structures affected by growth. The hygienist takes air and lift samples to be sent to the lab for comparison to outside levels. The samples are sent out to a lab, who tests each specimen and compares the results to a control group and samples from the outside environment. These tests help determine whether the spore levels inside the structure are outside of the safe range. If the structure "fails" the preliminary test, the hygienist will write a protocol that remediation companies can follow to help deem the structure safe. Here at SERVPRO of Lake County, we frequently work with protocols. Growth jobs can include setting containment, demolition, and micro cleaning. Our crews work diligently to clean the affected areas and reduce spore counts. After mitigation is complete, the hygienist will return to perform a post-test. This test shows whether the mitigation efforts were successful or if further action must be taken.
