Abstract
Abstract A device for protecting structures from corrosion and the like during storage is disclosed wherein the device includes a carrier defining at least one opening therein. The opening contains a mixture of organic ammonium nitrites with varying vapor pressures, a chemical buffer system for neutralizing lead acids, and any of a class of volatile anti-oxidants for preventing the formation of varnish and scavenging oxygen from varnish deposits. The carrier also contains means for attaching it to the structure to be protected.
