Determining conditions of components removably coupled to personal protection equipment
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.
1. A method comprising:
providing at least one filter removably coupled to an article of respiratory personal protection equipment that can be worn by a user;
providing at least one smart tag coupled to the filter;
receiving, by a computing device, sensing data about hazardous materials in a working environment using sensors prior to use of the filter;
receiving, by the computing device, data including time of use information from the smart tag; and
determining, by the computing device and using at least one predetermined criterion of concentration level or flow rate through the filter, a remaining life of the filter based on the time of use of the filter data retrieved from the smart tag and sensing data about the hazardous materials in the working environment.
2. The method of claim 1 , further comprising establishing the at least one predetermined criterion for the filter based on retrieving a set of rules that establish criteria and processing the sensing data about the hazardous materials.
3. The method of claim 2 , further comprising sensing the working environment by at least one of the sensors after obtaining the sensing data about the hazardous materials for use in establishing the predetermined criterion.
4. The method of claim 1 , wherein a determination of a condition for the filter is communicated to the user of the filter.
5. The method of claim 4 , further comprising verifying that the filter was processed following the determination.
6. The method of claim 1 , further comprising generating reports.
7. The method of claim 1 , further comprising generating reports about the determination of the remaining life of the filter.
8. The method of claim 1 , wherein the determining further includes determining the extent-of-service life remaining for the filter in the working environment.
9. The method of claim 1 , further comprising providing location information.
10. A system for determining end of life for a filter that is adapted to be removably coupled to an article of respiratory protection equipment, the system comprising:
at least one filter removably coupled to an article of respiratory protection equipment that can be worn by a user;
at least one smart tag coupled with filter;
a sensor to sense hazardous materials in a working environment prior to use of the filter;
an information retrieving system including one or more data acquiring devices;
the smart tag being operable to communicate with the one or more data acquiring devices for transmitting data including time of use information from the smart tag; and
a data processing system coupled to the information retrieving system, the data processing system including a mechanism for determining a remaining life of the filter based on comparing tracked time of use of the filter data retrieved from the smart tag and contaminant levels in the working environment against at least one predetermined criterion of concentration level and flow rate through the filter.
11. The system of claim 10 , further comprising establishing the at least one predetermined criterion for the filter based on retrieving a set of rules that establish criteria and processing the sensing data about the hazardous materials.
12. The system of claim 11 , further comprising sensing the working environment by at least one of the sensors after obtaining the sensing data about the hazardous materials for use in establishing the predetermined criterion.
13. The system of claim 10 , wherein a determination of a condition for the filter is communicated to the user of the filter.
14. The system of claim 10 , further comprising generating reports.
15. The system of claim 10 , further comprising generating reports about the determination of the remaining life of the filter.
16. The system of claim 13 , further comprising verifying that the filter was processed following the determination.
17. The system of claim 10 , wherein the determining further includes determining the extent-of-service life remaining for the filter in the working environment.
18. The system of claim 10 , further comprising providing location information.
