@bidens_diaper @J_D_Klein @HalCranmer Mitigating transmission is not the same thing as hazardous material PPE. If you reduce transmission by half, that's enormously beneficial. Reducing silica inhalation by half is a failure.
@bidens_尿布@J_D_Klein@HalCranmer缓解传播与危险品PPE不是一回事。如果你将传播减少一半，那将是非常有益的。将二氧化硅吸入量减少一半是失败的。
