A system includes a computing device a personal protective equipment (PPE) device. The PPE device is configured to be worn by a worker and includes and at least one physiological sensor configured to generate physiological data indicative of one or more physiological characteristics of a worker. The computing device is configured to determine a safety risk score for the worker based at least in part on the physiological data and a risk profile associated with the worker.

Personal protective equipment and safety management system having active worker sensing and assessment

An air filter includes filter media, a sensor, and circuitry coupled to the sensor, the circuitry configured to receive data from the sensor representative of the condition of the filter media and wirelessly transmit such data. The data may be received by a device with a display to use the information to present an indication of the filter media condition to a user.

Air filter condition sensing

Devices, systems and methods for obtaining data representative of the condition of an air filter media of an air filter installed in a powered air-handling system, and for using such data to present an indication of the air filter media condition to a user. The devices, systems and methods use pressure information representative of at least a downstream pressure of the powered air-handling system.
