Respirator Protection Devices and Methods to Detect and Remove Toxic Gases from the Air - Cobinamide Encapsulated Silica-based Materials for Respirator Canisters
A respirator protects the wearer from inhaling dangerous substances, such as chemicals and infectious particles.
CDC developed devices and methods to detect and remove chemicals such as hydrogen cyanide, cyanogen, hydrogen sulfide, nitrite, and nitric oxide from the air for those wearing respirators. Cobinamide (a Vitamin B12 analog with a high affinity to cyanide) molecules are immobilized within a silica matrix that allows for the infiltration and containment of gaseous chemicals.
