An incinerator room to store secret documents and destroy them automatically according to a burn sequence by spraying slow burning flammable liquid on the contents of said room from one or more reservoirs. A control circuit, preferably supplied with energy from a secure source such as a battery, controls the ignition sequence to spray the flammable liquid, then start ignition means and start an exhaust fan and open optional electrically operated shutters or flue. The electrically operated flue prevents unauthorized access to the room by humans or fiber optic spying apparatus via ingress through the chimney of the exhaust system. Pressurized reservoirs and electrically operated valves are used in the preferred embodiment.
