ABSTRACT

Laboratory tests on the bursting of vent closure materials were made by the Eastman Kodak Company. In practice, a vent opening in a vessel, building, or in an attached duct is usually covered by a closure which opens in the event of an explosion. The closure offers protection against weather, confines the combustible within the vessel, and prevents contamination of the product. In practice, closures which do not burst or tear out of place during the venting of an explosion are often used to protect equipment and buildings. Some examples of these closures are plastic domes, blowout panels and swinging doors. The swinging door, if securely attached, is not thrown outwardly by an explosion. Limited experiments were made to explore methods for suppressing a dust explosion in the vented gallery, for preventing flame projection from a vent and for quenching flame in an attached duct.
