Example 4 – Explosion venting and isolation of a dual-leg bucket elevator. This design assumes elevator is located out- doors or close to an outside wall. Explosion isolation is pro- vided using EHRD type suppressors. Explosion detection is done by SmartDS rate of rise explosion pressure detectors along with IR flame detectors. Explo- sion propagation risks to interconnected vessels are minimized with the use of the isolation system. It is critical that all the systems and components used as a part of an ex- plosion protection system should be third party ATEX approved. Explosion pro- tection and prevention systems are life critical systems thus should be designed by system sup- plier’s qualified design en- gineers as well as should be maintained only by manufacturer approved service personnel. Properly designed and protected feed mill or a grain handling facility would provide a safer work environment to the employees while minimizing unplanned downtime due to dust explosions.
