BS&B Safety Systems Explosion Suppression — BS&B Safety Systems: Explosion Suppression. Manufacturer equipment example.

Explosion Suppression for your process

Detect a developing explosion and discharge suppressant into the protected volume.

BS&B industrial suppression systems use detection, controls and suppressant discharge devices to act during the early development of an explosion. The system is designed around the vessel, process, combustible material and the required protected pressure.

Example: Assess suppression for a vessel where explosion venting is not the preferred protection method.

Also known as: Chemical explosion suppression, IPD suppression systems, active explosion protection.

Act on an early signal

detector arrangement and response belong to the complete system design.

Distribute suppressant

device number, position and agent are selected around the protected volume.

Integrate the process

alarms, shutdowns, inspection and reinstatement procedures need planning.

How It Works

Detect the developing event

Command the suppression devices

Distribute agent within the designed protected volume

Typical Materials & Industries

Dust collectors

internal geometry and dust conditions influence system design.

Dryers and processing vessels

temperature and pressure conditions require review.

Powder systems

product compatibility and connected equipment must be considered.

Protection-method overview

BS&B introduces venting, flameless venting, chemical suppression and chemical isolation. This is an overview of protection roles, not a sizing demonstration or a project-specific design.

Configuration & Application Review

Equipment duty: Detect a developing explosion and discharge suppressant into the protected volume.
Selection basis: Dust test data, vessel strength and volume, connected ducts, operating conditions, personnel locations, equipment layout, and the project hazard assessment.
Available configuration review: Detection arrangement, Suppression device selection, Suppression agent, Control and shutdown interface, Vessel interfaces, Service and reinstatement plan.
Application verification: No. Vessel suppression and propagation isolation are separate protection functions. Review connections and isolation requirements as part of the complete hazard assessment.

Application Questions

Does suppression also isolate every connected duct?

No. Vessel suppression and propagation isolation are separate protection functions. Review connections and isolation requirements as part of the complete hazard assessment.

What should I send RTS for a review?

Dust test data, vessel strength and volume, connected ducts, operating conditions, personnel locations, equipment layout, and the project hazard assessment.

Relieve pressure

Explosion Vents >>

Relieve explosion pressure through a designed discharge path.

Example: Review venting on a dust collector with a discharge route to an appropriate safe area.

Also known as: Explosion relief panels, dust explosion vents, rupture vents.

Quench vented flame

Flameless Explosion Venting >>

Manage vented flame where an open flame discharge is unsuitable.

Example: Review an indoor dust collector where a conventional outdoor vent route is impractical.

Also known as: Flameless vents, FlameFree venting, IQR systems.

Isolate chemically

Chemical Explosion Isolation >>

Limit flame propagation through a connected process duct.

Example: Assess the duct between a protected dust collector and connected process equipment.

Also known as: Chemical barriers, active explosion isolation, IPD chemical isolation.

Isolate physically

Mechanical Explosion Isolation >>

Create a physical barrier in a connected process route.

Example: Assess active physical isolation in a duct connected to explosion-protected equipment.

Also known as: Mechanical isolation devices, active explosion isolation valves, IVE isolation.
