Blood appears throughout the novel as a symbol of a human being’s repressed soul or primal, instinctive self. Montag often “feels” his most revolutionary thoughts welling and circulating in his blood. Mildred, whose primal self has been irretrievably lost, remains unchanged when her poisoned blood is replaced with fresh, mechanically administered blood by the Electric-Eyed Snake machine. The symbol of blood is intimately related to the Snake machine. Bradbury uses the electronic device to reveal Mildred’s corrupted insides and the thick sediment of delusion, misery, and self-hatred within her.

This relates to Fahrenheit 451, how Firemen used to put out fires, opposed to setting them. Firemen would save citizens from house fires or building fires and assemble rescue teams for more safety. However, the Firemen described in the book, set fires by burning people’s homes and personal assets...
