Abstract
An environmental protection system for rendering biological/chemical agents harmless has a source of radiation such as an ultraviolet light source, which is configured to irradiate a reactive surface, such as one formed of titanium dioxide. The reactive surface has an oxidation potential sufficient to cooperate with the source of radiation so as to render harmless biological/chemical agents in contact with the reactive surface.
Claims12
A serial multistage protective helmet for mitigating airborne biological/chemical agents disposed in an airstream flowing therethrough, the helmet comprising:
- (a) an air intake manifold for advancing the airstream therethrough;
- (b) a macrofilter disposed adjacent the manifold, the macrofilter being configured to filter a first portion of the agents from the airstream;
- and
- (c) an optical fiber reactor disposed downstream of the macrofilter and comprising:
- (1) a plurality of optical quartz fibers each layered with titanium dioxide forming a reactive surface;
- and
- (2) a source of radiation disposed proximate the surface, the source of radiation being configured to illuminate the reactive surface;
- (3) wherein the reactive surface is provided with an oxidation potential such that, upon exposure of the surface to the source of radiation, a second portion of the agents are filtered from the airstream.
