    Scope & contentMark Shannon from BS&B Safety Systems shares key tips on ensuring adequate protection from dust explosions and what mistakes to avoid devastating grain dust explosions have been recorded for decades as the risk of flour dust ignition is so high. Without adequate controls and safety measures, grain flour explosions have been known to level entire milling facilities and take lives. While mill owners are making the effort to comply with DSEAR and ATEX regulations to ensure their staffs’ safety, the execution of preventive measures has not always been correct. Many milling facilities share common problems when it comes to the installation of protective equipment. In some cases, they inadvertently exclude “fail-safes” where necessary.

    Here are some examples of the most regularly encountered issues when it comes to protecting against dust explosion risk in grain processing and milling. These observations come from years of experience. Always seek the help of a professional to visit your site and make the recommendations bespoke to your facilitys’ needs.
