⁣Kristen Meghan Kelly - Grandville board meeting August 2021. Over 19 years experience in mitigation training and Senior Industrial Hygienist that works in Occupational and Environmental Toxicology. She teaches the “experts” on how to effectively use a mask. Says masks do not work and instead the schools should use their covid funds for engineering controls (10k per building) for technology that kills all viruses, bacteria, and mold in the buildings - which is not only great for now but great for everything. Says to look up Petty Podcasts which talks about source control/engineering controls and listen to the subject-matter experts.
