BS&B Safety Systems

BS&B Safety Systems, headquartered in Tulsa, Oklahoma, manufactures pressure relief and explosion protection equipment used in powder and bulk solids processing. Its product range includes rupture disks, explosion vents (VENT-SAF), and the IQR System, a combined explosion vent and quenching module that vents deflagration pressure while a stainless steel mesh quenches the flame and retains dust; BS&B states the quenching module typically stays below 100 degrees C during activation, compared with dust explosion fireball temperatures of about 500 degrees C. The IQR System is intended for indoor installations where venting a dust explosion to the outside is impractical, and BS&B references NFPA 68 and NFPA 654 in describing this equipment. The company also lists active explosion protection such as suppression and isolation systems, spark detection, and chemical isolation barriers for combustible-dust applications including silos, bucket elevators, mills, and dust collectors.
