![]() ![]() The most common explosion proof lighting fixtures for grain storage areas are linear and high bay lighting, as they are typically mounted high above in order to provide clearance for varying levels of grain within the storage silos. However, the biggest difference is that grain storage covers a much larger area, which necessitates different lighting fixtures with a broader beam pattern. Grain storage areas require similar types of lighting fixtures, due to similar hazards involving grain dust. Proper lighting for these facilities allows for optimal illumination and visibility for workers, making their work safer and more efficient. ![]() Combined with high foot traffic and a number of moving machines, it is critical that these plants are equipped with explosion proof lighting systems. Grain processing plants generate a large amount of combustible organic dust, through the processing of wheat, barley and other crops. This standard covers everything from explosive gasses to flammable liquids and combustible dust. The main standard used for grain processing and handling is Class 1 Division 2, which is governed by the standard UL 844 and the National Electric Code (NEC) article 501. There are several industry standards for explosion proof lighting that are commonly used in grain storage facilities. Because of this, lighting used in facilities handling grain must be sealed from the outside environment to prevent accidental fires and explosions. The largest section of a facility's electrical system is the lighting system, which not only physically comprises the majority of the electrical components but also generates considerable amounts of heat. Because of this, electrical systems within grain handling facilities are shielded from dust and vapor ingress, eliminating a possible source of ignition. Remember, ignoring the safety tips given above could cost you your life.The most common source of accidental ignition of grain dust is sparks from exposed electrical components. However, the good news is that workers can considerably reduce their chances of being injured or dying inside a grain silo by following the safety tips we have listed above. All of these things will help to keep you and your colleagues safe in an emergency. No one should enter a grain silo unless they have been given adequate training in first-aid, fire suppression, rescue, and personal protection. Always ask somebody to stay close by so that they can call for help should you need it. One of the best tips we can give you is to make sure that you are not on your own when working in a silo. Always Have a Person on Stand-By Outside of the Silo ![]() It is much better to contact your local emergency team who have all of the right training and equipment to do the job safely. Primary dust explosions may occur inside process equipment or similar enclosures, and are generally controlled by pressure relief through purpose-built ducting to the external atmosphere. Although it may be possible to rescue the individual yourself, by going into the grain silo you are putting yourself at risk. If you notice that one of your colleagues is missing or you realize that they are trapped inside a grain silo, then call 911 for help. This will help you to stay safe while working in a grain silo. Turning off the circuit will ensure that no grain can flow into or out of the silo while you are inside. ![]() Lock Out the Control CircuitĪlways lock out the control circuit before you enter a bin. However, if you find yourself covered in flowing grain, and you cannot move, then stay where you are, cup your hands over your mouth, and take little breaths until someone arrives to rescue you. Once you are here, you will need to continue walking until the grain flow stops or the bin is empty. If you find yourself trapped in a grain silo, with nothing to grab onto, but you can still move about and walk, then make sure you move to the edge of the silo wall. Thanks to this, you can become totally submerged in just 8 seconds, leaving you helpless. Today’s large grain silos can transfer up to four times as much grain as silos in the past. It is often hard to stay safe when dealing with bulk material. If Trapped, Remain Near the Edge of the Silo If you work in a grain silo, then here are some important safety tips: 1. Thankfully, workers can reduce their chances of being injured or dying in a grain silo by following the safety procedures put in place. The Department of Labor has recently reported that it can take just five seconds for a worker to become trapped and engulfed in flowing grain, and only 60 seconds to become completely submerged and suffocate. with grain bin entrapment being one of the main causes of death. Every year, over nine hundred grain bin fatalities occur in the U.S. ![]()
