explosion before it can develop into a destructive event. Explosion isolation Preventing an explosion from propagating to interconnected systems is another key safety measure. Chemical barriers, such as those used in suppression systems, can stop flames from spreading. Additionally, active mechanical isolation solutions, including Redex active isolation valves and IVE pinch valves from BS&B, act as physical barriers to contain explosions within a specific section of a process. Pressure relief systems In areas where controlled venting is an option, pressure relief systems, such as BS&B’s rupture discs and FlameFree pressure relief solutions, provide another layer of protection. These systems activate instantly upon reaching a predefined pressure threshold, allowing pressure waves to escape while preventing flame propagation. Options such as the R-IQ and IQR FlameFree systems incorporate multi-layer stainless steel filters that retain burning particles while ensuring pressure is safely dissipated. Integrated safety strategies Given the complexity of dust explosion risks, implementing a combination of suppression, isolation, and pressure relief measures ensures comprehensive protection. Solutions such as the SparkEx spark detection system, which identifies and neutralises ignition sources before they lead to an explosion, further enhance safety. Process managers must prioritise explosion protection as part of equipment design and operational safety protocols. Certified solutions, such as those offered by Bormann & Neupert by BS&B, provide industry-compliant protection while supporting long-term operational efficiency. By integrating these measures, manufacturers can mitigate risks, maintain regulatory compliance, and ensure the continuous and safe production of foodstuffs and animal feed. ! ! !"#$%&!'()*+&!,-".&/0$12& 34.&%5%67%87"&9-4$&2:4,;&& & ! !"#$%&'()*+,)-./,%"'#0)1+2(,3)'"&,#0%4+53)0++'#563)7'$,%4+5)8) $,%59*(,)%11'#0%4+59:);,(99",(9)"1)$+)<=)&%,)6)%5/)'+2)9+"5/:) >%'')"9?)=@A<B)AB=@=A) (C%#'?)9%'(9D%11'#(/1"C19:0+:"E) F#9#$?)222:%11'#(/1"C19:0+:"E) www.hpmag.co.uk HYDRAULICS & PNEUMATICS March 2025 31 FlameFree pressure relief systems like the rectangular R-IQ version shown here allow the pressure wave to escape while reliably retaining flames and particles. This protects the machinery and systems.
