Determination of Metal Sparking Characteristics and the Effects on Explosive Dust Clouds

Abstract

Of major concern in industry are hazards posed by metal-to-metal sparking in environments where potentially explosive dusts are present. The probability of ignition of a dust cloud by metal sparking is dependent on many factors including the type of metal, the contract speed of the metal surfaces, the contact time of the metal surfaces, the pressure on the contact surface and the type and concentration of the dust cloud present. Metal sparking tests were performed as part of a hazard analysis program. The purpose of the test was to determine the sparking characteristics of a series of metals and the effects of the sparks produced on several types of dust clouds.
