Grain dust explosions. The May 2018 explosion in South Sioux City, Nebraska, U.S., damaged the structure, injured two workers, and interrupted business operations. Many improvements in design, monitoring, maintenance, and training employees have reduced the number of explosions that occur. 1.1 Explosions and fires within the food industry from combustible materials are a known hazard and they can have devastating and irreversible effects. Brooms, with antistatic bristles, are easy to operate and have no regulatory constraints, but they require an operator, which can be difficult to find, especially during busy periods. Because of the operating environment in grain handling facilities, the potential hazard of combustible dust can never be completely eliminated. Several area fire departments helped put out the fire, which occurred before 8:00 a.m. in an elevator shaft. A dust explosion is the rapid combustion of fine particles suspended in the air within an … Fuel: Grain Dust Industry: Animal Feed Products (Food Products) Equipment: Grain Elevator. (2012) Farm and Ranch eXtension in Safety and Health (FReSH) Community of Practice. Oxygen and confined spaces are part of handling grain and cannot be eliminated. The dispersed combustible dust clouds in the air form an explosive … Agricultural Dust Explosions in 2018* There were 12 grain dust explosions reported in the U.S. in 2018 according to Kingsly Ambrose, Associate Professor, Purdue University. The parameters of dusts Natural Min. temperature Min. From this graph, we could see that explosions could occur any time of the year. Of the 104 explosions reported from 2005 through 2017, the ignition source and fuel source remained unidentified in nearly 70 incidents, according to information collected by Purdue University. Additionally, grains are handled and processed differently based on industry type. For a grain dust explosion to occur, five components must be in place: oxygen, confined space, ignition source, dispersion, and a fuel source (grain dust). An advanced workshop addresses grain handling and conveying equipment maintenance as it relates to grain dust, preventive maintenance in grain and feed handling and processing facilities, control mechanisms for use during unloading and grain handling, controls of bucket elevator operations to limit dust, and use of advanced engineering controls such as appropriate sensors and explosion vents. With the improvement of application technology of grain silo/ fly ash steel silo, steel silo has become the mainstream of these industries. Grain dust is highly combustible, so a fire or an explosion can happen at a large grain-handling facility or in a grain-storage area on a local farm or ranch. Purdue University and Iowa State University have taken a leading role in raising awareness of grain dust hazards. Eliminating one of these five elements will prevent an explosion, but elimination of these hazards is not a simple process. Very high airborne dust concentrations can introduce the risk of explosion. Grain dust explosions of any size can cause damage to equipment, reduced work time, and injury or death. A second explosion in eastern France in June 2018 injured six and destroyed the facility. Dust Explosion. 2 The guidance note is particularly aimed at employers and managers. Grain dust is highly combustible, so a fire or an explosion can happen at a large grain-handling facility or in a grain-storage area on a local farm or ranch. This news segment produced by St. Louis-based NBC News affiliate KSDK captures the aftermath of a deadly and destructive grain dust explosion and fire that rocked a Ralston-Purina facility in St. Louis on Jan. 10, 1962. In this episode of the DustSafetyScience Podcast, we talk to Dr. Suzanne Smyth about a case study involving a grain dust explosion in a milling facility. Retrieved from http://www.osha.gov/SLTC/grainhandling/index.html. Another method for controlling dust is to adjust the angle of spouting to reduce grain speed as it moves from one bucket elevator to another conveyor. This compares to 12 in 2018 and a ten-year average of 8.5 explosions. Vacuums and compressed air have applicable standards and regulations and have advantages and disadvantages. As a result, safety requirements may vary, leading to a discrepancy in the literature and confusion about best practices for managing grain dust hazards. It also requires thorough housekeeping procedures to keep dust from accumulating on surfaces. Further, having safety standards and implementing these standards consistently can be an obstacle. Managing grain dust and maintaining equipment is not a once-a-year task, rather, these tasks should be approached as an ongoing, scheduled, continuous improvement process. Narrow opinions such as “nothing has happened until now” or “accidents occur no matter how much you train the workers” must be overcome to successfully deliver the safety message about grain dust explosion threats faced by the grain handling and processing industry. Therefore, managing housekeeping related to grain dust and appropriate maintenance of equipment to prevent ignition sources from sparking and dispersing is a critical challenge. Database Incidents: None Recorded. During the operations of loading and unloading, such layers, because of the motion due to the circulation of air, always generate a permanent cloud. This compares to 7 in 2017 and a ten-year average of 8.4 explosions. Facilities with a smaller budget have options to minimize grain dust hazards in their facility, but they must take the hazard seriously. Retrieved from http://www.extension.org/pages/63142/grain-dust-explosions. The dust from the first explosion may actually provide fuel for the secondary explosion by shaking loose settled dust. During loading and unloading operations, these layers can generate a dust cloud as particles are sucked up by the circulating air. One of the challenges of prevention is that it is often difficult to complete an incident investigation of explosion events after occurrence. The small particles of most grains mean that grain dust and the flour that can result from grains such as wheat should always be considered combustible. Four basic elements must be present for a grain dust explosion to occur: fuel, oxygen, confinement, and an ignition source. The grain handling and processing industry has made good progress in preventing grain dust explosions through enhanced engineering controls and interventions, improved grain handling methods, and increased awareness of employees and managers about grain dust hazards. From Eckhoff (2003). On December 30, 2020, Feed & Grain reported a fire at a grain elevator in Homer, Illinois. A common question is: How much dust is needed to cause a grain dust explosion? PREVIOUS. One of the particles especially vulnerable to combustion is grain dust, found in grain handling facilities. The standard requires testing for combustible dust presence in all storage containers (silos, tanks, bins). Figure 5-42 Damaged silo roof after the wheat grain dust explosion in Stavanger in June 1970. Company: M-G, Inc. A second important prevention practice is a consistent housekeeping schedule. If fuel, oxygen, and an ignition source are present in a confined space, a series of destructive explosions can occur that may cause structural damage.
