Multi-layered hazardous material containment bag
View Patent ↗A hazardous material containment bag and bag system for handling and transporting contaminated material or human remains is provided. The bag has a multi-layered structure that minimizes contamination by a chemical, biological, radiological and/or toxicological agent. The bag has an absorbent and/or adsorbent layer, which will help keep any hazardous components dissolved in bodily fluids immobilized inside the bag. The bag also has an active agent in at least one layer individually selected to neutralize or trap more than one type of contaminant. A bag system is also provided having an inner bag and a separate outer bag with the inner bag being a multi-layered structure having an absorbent material, which will help immobilize hazardous liquid, bodily fluids, and/or gases emanating from a contaminant enclosed in the inner bag. A method for using the hazardous material containment bag and bag system is also provided.
1. A hazardous material containment system for the handling and transporting of contaminants, comprising:
an outer bag;
an inner bag inside of and enclosed by the outer bag, wherein the inner bag encloses all or part of the contaminants and prevents the contaminants from escaping;
an inner closure connected to the inner bag for providing access to an interior of the inner bag;
an absorbent core made of an absorbent material, wherein the absorbent core is in the inner bag for absorbing liquids from the contaminants;
an active agent in the absorbent core for neutralizing or minimizing contamination of the contaminants, and
wherein the inner bag further comprises an exterior shell that surrounds the absorbent core, wherein the exterior shell provides stability to the inner bag, and wherein the absorbent core has a greater circumference than the exterior shell to cover the inner closure and prevent gases from escaping through the inner closure.
2. The hazardous material containment system of claim 1 , further comprising an outer closure connected to the outer bag for providing access to an interior of the outer bag, and wherein the inner bag is removable from the outer bag by opening the outer closure.
3. The hazardous material containment system of claim 1 , wherein the outer bag comprises a nylon material with a polymer backing.
4. The hazardous material containment system of claim 1 , wherein the inner bag further includes:
a first layer adjacent the absorbent core; and
a chemical barrier adjacent the first layer to contain the contaminants in the inner bag, and
wherein the exterior shell is adjacent the chemical barrier.
5. The hazardous material containment system of claim 4 , wherein the first layer is a carbon cloth laminated to the absorbent core.
6. The hazardous material containment system of claim 4 , wherein the exterior shell comprises a thermal polyurethane.
7. The hazardous material containment system of claim 1 , wherein the active agent is an antimicrobial, a quaternary ammonium compound, active carbon, nanoparticles, and combinations thereof.
8. The hazardous material containment system of claim 1 , wherein the inner closure is waterproof.
