Abstract
A computing device is described, which includes a processor and memory with instructions. When executed, these instructions enable the processor to: receive data about gas characteristics in a sealed space between a wearer's face and a negative pressure reusable respirator; assess the performance of a respirator seal check by the wearer; detect if the respirator is being worn; take specific actions if the respirator is worn but the seal check does not meet safety standards; and modify these actions if the seal check meets safety standards. A system incorporating this computing device is also described.
