Vessels at sea face a complex and volatile environment, where an onboard explosion from causes like fuel leakage or electrical failure poses a catastrophic threat to structural integrity, critical systems, and personnel safety. This disaster is primarily driven by the ensuing blast wave–a rapid surge in pressure and flow that follows the initial event. It is therefore critical to equip vessels with blast protection devices specifically designed to mitigate damage from this destructive pressure wave. Halton BDH Blast Damper provides this vital protection, validated by rigorous testing to automatically close ventilation openings and prevent the spread of the blast wave.
Certified Protection Through Rigorous Testing
Halton BDH is widely tested by 3rd party research centers as well as internal testing conducted to ensure reliable operation under extreme explosion scenarios. It has undergone shock tube testing for both detonation (shock) and deflagration (blast) type pressure waves in full compliance with GSA TS01 and ASTM F 1642-04 (2010) standards, demonstrating effective resistance against high-intensity blast waves. BDH has also completed debris impact tests using steel balls and wood plank missiles according to ASTM E 1886-13a and ASTM E 1996-14a, proving its ability to block flying explosion debris and protect personnel and equipment inside the vessel. Furthermore, the BDH is ATEX/IECEx certified for use in hazardous Zones 1 & 2, providing reliable blast protection for vessel operations.
Key Operational Advantages
Halton BDH provides critical operational benefits as a mechanical damper designed to withstand high blast pressures. Its core safety function is to immediately close the air passageway when activated, preventing blast pressure from penetrating protected spaces. The unit features an adjustable activation pressure (0.1-1 bar) with minimal pressure drop while offering complete protection against both blast and suction phases. Its versatile installation allows vertical/horizontal mounting on walls, roofs, or between ducts. When blades are in the open position, the device maintains minimal pressure loss, noise, and flow disturbance. For enhanced protection, an optional debris catcher is available. Requiring only annual maintenance checks, the damper ensures long-term reliability with minimal operational burden. Halton BDH is manually armed and remains securely closed after blast events until re-armed.
