• Description:
  Information was gathered concerning actual dust explosions in industrial situations and experiments were conducted to study primary and secondary dust explosions. From the years 1984 through 1987 a total of 69 explosions in agricultural facilities resulted in 15 deaths and 57 injuries to workers. Investigation has indicated that the five components necessary to support a dust explosion were present including fuel, oxidizer, ignition, mixing, and confinement. In facilities where secondary explosions have occurred the levels of housekeeping were poor. A variety of ignition sources were identified including welding, choked bucket elevators, electrical equipment and appliances, bearings, and foreign material. The Premixed Turbulent Combustion Bomb (PTCB) was used to study primary dust explosions. The PTCB also provided data on turbulent flame propagation. The Flame Acceleration Tube (FAT) was used to study secondary dust explosions. Using the FAT, the minimum thickness required for a dust layer to support an explosion was determined; the thickness was about three times as thick as calculated using Hartman Bomb lower explosive limit data.
