Abstract
Apparatus and methods for detecting the permeation of hazardous or toxic chemicals through protective clothing are disclosed. The hazardous or toxic chemicals of interest do not possess the spectral characteristic of luminescence. The apparatus and methods utilize a spectrochemical modification technique to detect the luminescence quenching of an indicator compound which upon permeation of the chemical through the protective clothing, the indicator is exposed to the chemical, thus indicating chemical permeation.
Claims26
An article of protective clothing adapted for detecting the permeation of a chemical through said article, comprising:
- a. an article of protective clothing material having an inner surface and an outer surface;
- and
- b. an indicator supported on said inner surface, said indicator having luminescent characteristics which are modified upon contact with said chemical.
An article of protective clothing adapted for detecting the permeation of a chemical through said article, comprising:
- a. an article of protective clothing having an inner surface and an outer surface;
- b. a substrate secured to said inner surface;
- and
- c. an indicator supported by said substrate, said indicator having luminescent characteristics which are modified upon contact with said chemical so that upon permeation of said chemical through said article, said chemical will contact said substrate, indicating permeation of said chemical.
A method for adapting an article of protective clothing for detecting the permeation of a chemical through said article comprising the steps of:
- a. providing an article of protective clothing material having an inner surface and an outer surface;
- and
- b. treating said inner surface with an indicator, said indicator having luminescent characteristics which are modified upon contact with said chemical.
