EXPLOSION VENTING IQR SYSTEM™ BS&B PRESSURE SAFETY MANAGEMENT, L.L.C. FLAME, DUST and PRESSURE CONTROL • INTERCEPTS • QUENCHES • RETAINS

Flame Arresting – No flame escapes providing a safe operating environment for personnel. Eliminates the possibility of a secondary ignition and subsequent explosion external to the protected equipment. Dust Retention – Retains process product removing the possibility of potentially toxic product entering the environment. Pressure Retention – Absorbs explosion pressure peak, protects personnel and surrounding environment from pressure blast. Temperature Control – Absorbs fireball with negligible temperature rise in surrounding environment. HOW THE IQR SYSTEM™ WORKS The IQR system comprises two...
