Method and system are disclosed for determining conditions of components that are removably coupled to articles of personal protection equipment (PPE) by tracking the components against predetermined criteria.

Determining conditions of components removably coupled to personal protection equipment

A system includes a respirator, a sensor including a sensing element, and a reader configured to be in wireless communication with the sensor. The sensor is positioned substantially within an interior gas space of the respirator.

Sensing system for respirator

The present disclosure is particularly adapted for determining whether the condition of personal protection equipment PPE articles satisfies at least one criterion. A method and system provide at least one predetermined criterion that governs use of the PPE article in a working environment; a PPE article is configured with a smart tag, and a sensing device is provided that is configured to sense data in a working environment related to the predetermined criterion. Acquired data from the sensing device and the smart tag are processed in a data processing system to determine whether the condition of the PPE article satisfies the at least one predetermined criterion.

Personal protection article system

A method of fit testing includes providing a respirator; providing a sensor having a sensing element removably positioned substantially within an interior gas space of the respirator; providing a reader configured to be in wireless communication with the sensor; positioning the respirator over a mouth and a nose of a user while the sensor is positioned substantially within an interior gas space of the respirator; and observing respirator fit assessment data communicated from the sensor to the reader.

Fit-test method for respirator with sensing system

This disclosure relates generally to methods and systems for determining whether at least a first component and a second component of a personal protection (PP) configuration are compatible so as to be assembled into an approved PP configuration, responsive to being compared against at least one predetermined criterion. Included is a smart tag for each of the first and second components. The first and second smart tags include respective first and second data. A data acquiring system is provided for acquiring the first and second data and a data processing system processes the acquired first and second data for determining if the first and second components are compatible to be assembled as an approved PP configuration.

Determining compatibility of components for assembling approved personal protection configurations

An air filter including a filter support that supports polymeric sorbent particles. The polymeric sorbent is the reaction product of a divinylbenzene/maleic anhydride precursor polymeric material with a nitrogen-containing compound. The air filter may be used for capturing e.g. reactive gases.
