Sandman (DC Comics)

Sandman is a superhero appearing in American comic books published by DC Comics. The first of several DC characters to bear the name Sandman, he was created by writer Gardner Fox and artist Bert Christman. Attired in a green business suit, fedora, and World War I gas mask, the Sandman used a gun emitting a sleeping gas to sedate criminals. He was originally one of the "mystery men" to appear in comic books and other types of adventure fiction in the 1930s, but later was outfitted with a unitard/cowl costume and developed into a proper superhero, acquiring a sidekick, Sandy, and founding the Justice Society of America (JSA).

A gas mask is a mask used to protect the wearer from inhaling airborne pollutants and toxic gases. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Most gas masks are also respirators, though the word gas mask is often used to refer to military equipment, the scope used in this article. The gas mask only protects the user from digesting, inhaling, and contact through the eyes. Most combined gas mask filters will last around 8 hours in a biological or chemical situation. Filters against specific chemical agents can last up to 20 hours.
