What preventive measure should be implemented to control spore release from AFDs during shutdown and transport?

Sealing the intake with poly and tape is an essential preventive measure to control spore release from Air Filtration Devices (AFDs) during shutdown and transport. This action effectively prevents contaminants, such as mold spores, from escaping into the environment. When the intake is secured, it acts as a barrier that limits the potential for spores to become airborne during the transition period when the equipment is turned off and moved.

This measure is particularly critical because AFDs are designed to capture and filter airborne contaminants, and if not properly sealed during transport, they can inadvertently release trapped spores back into the air, which poses a risk of further contamination to the surrounding area. By ensuring that the intake is sealed properly, the integrity of the filtration system is maintained, reducing the likelihood of cross-contamination during transportation.

Taking these precautions aligns with best practices in microbial remediation, where controlling potential spore dispersal is a priority to ensure safety and effectiveness throughout the remediation process.
