摘要： A protective system for respiration, and a management method facilitates stably supplying filtered air for safety such that the equipment management or the safety management can be performed remotely. The protective equipment includes a main body that covers the face of an operator, a fan unit including an air filter and an electric fan, a detecting section, a first control section, and a first communication section. The detecting section detects a physical quantity concerning at least one of a work environment of the operator, an action state of the operator, and an operation state of the electric fan. The first control section controls the electric fan based on a detection result of the detecting section. The first communication section transmits first information indicating a detection result of the detecting section or second information concerning an operation amount on a control target of the first control section to an external device.

摘要： A mask fitting level determination device includes a mask inner pressure detection unit inserted between a mask covering a mouth, nose and a face surface of a person to measure a pressure inside the mask. A circuit control unit derives information of a pressure value measured by the mask inner pressure detection unit and generates display information for the person wearing the mask. A determination display unit shows the person the display information generated by the circuit control unit. A battery unit supplies electricity to the circuit control unit and the determination display unit. A power supply switch starts and stops the supply of the electricity to the circuit control unit and the determination display unit. A start switch starts the mask inner pressure detection operation.
