Comment on Dr. Dan Stock’s Testimony before the Mt. Vernon School Board by Herschell Hitchcock.
Your rationale, related to mask is false. If you stated that no mask prevented 100% droplet nuclei you would be correct. Please refer to Most penetrating particle size filtration. This is how we have BSL 3 and 4 laboratories. Not arguing with you, and don’t mind helping you. Your gonna get nabbed using your rationale.
