Flour decontamination with

Absorb contaminating agent with absorbent materials (e.g., rub with flour followed by wet tissues or use military M291 resin kits for spot decontamination of skin only). 

Decontamination studies have been conducted using common household products. The goal of these studies was identification of decontaminants for civilians as well as field expedients for the soldier. Timely use of water, soap and water, or flour followed by wet tissue wipes produced results equal, nearly equal, or in some instances better than those produced by the use of fuller s earth, Dutch Powder, and other compounds.4 (Fuller s earth [diatomaceous earth] and Dutch Powder [Dutch variation of fuller s earth] are decontamination agents currently fielded by some European countries.) Because no topical decontaminant has ever shown efficacy with chemical agent that has penetrated into the skin, and because chemical agents may begin penetrating the skin before complete reactive decontamination (detoxification) takes place, early physical removal is most important. 

If water is not available, talcum powder or flour are also excellent means of decontamination of liquid agents. Sprinkle the flour or powder liberally over the affected skin area, wait 30 seconds, and brush off with a rag or gauze pad. (Note The powder absorbs the agent so it must be brushed off thoroughly. If available, rubber gloves should be used when carrying out this procedure.)...
