Hazardex 2017 Awards - 1. Contribution to Safety - 1B. BS&B Safety Systems – System V chemical suppression and isolation system

19 January 2017

BS&B Safety Systems Full Entry: System V is an explosion protection solution.  It is a rapid response chemical suppression system that prevents flame propagation and isolates interconnecting process equipment. Its installation could prevent crippling equipment damage, loss of production time and possible injury to personnel.

When the Cannon™ deploys, it releases sodium bicarbonate to fully suppress a dust explosion. Cannon deployment is prompted by a low voltage electrical signal generated from sensors in a smart controller unit which subsequently activates the Cannon. The actuators release pressurised nitrogen gas towards a sodium bicarbonate canister which discharges its contents at high velocity in milliseconds. A possible deflagration travelling through ducts, piping and connected equipment is quickly and efficiently extinguished.

It is designed for installation in facilities that generate or handle combustible dusts posing potential explosion risks. The System V can be applied in industries including chemical, grain, animal feeds, food and recycling.

A major USP is that the suppression and isolation system can be activated by various means, whether triggered by pressure, optical or vent sensors. System V consists of a sensor and a uniquely designed modular Cannon™ comprising five components:  the Cannon™ body, extinguishing agent canister, actuation mechanism, pressurised nitrogen tank and the Cannon™ electrical enclosure.  The Cannons’ critical circuits are continuously monitored and any events are reported at a controller’s touch screen.

The System V has dual electrical and mechanical lockout mechanisms which prevent accidental discharge of a Cannon™ into the protected equipment. This also makes it safe for any operatives working on equipment nearby. 

The System V is easily maintained and refitted after activation and maintained. Due to its modular configuration and initially unpressurised canister, it is easily shipped to its destination point of use.
