Building Explosion Venting Area Calculation

To ensure effective pressure relief in buildings during explosive incidents and safeguard structural integrity and personnel safety, our company offers professional building explosion venting area calculation services. We assist you in designing venting solutions that comply with FM 1-44 standards.

Service Contents

  • Fuel Reactivity Group Determination: Based on the types of fuels potentially causing explosions within the building, we determine the fuel reactivity group (A to E) according to Table 2.1.1 of FM 1-44 standard.
    • If multiple fuels are present, the most reactive fuel will be used as the design basis.
  • Venting Area Calculation: Using formulas provided by FM 1-44 standard, we precisely calculate the minimum required venting area.
    • Calculations consider the building’s internal surface area (As) and the As/Av value determined by the fuel reactivity group.
    • We provide a detailed calculation report, including parameter values and calculation processes.
  • Venting Device Selection and Layout Recommendations:
    • Based on calculation results and fuel reactivity group, we recommend suitable vent panels with reference to Table 2.1.2 of FM 1-44 standard, including static activation pressure (Pv) and maximum weight of vent panels.
    • We provide optimal layout solutions for vent panels, ensuring uniform distribution on building surfaces and proximity to the building center to enhance venting effectiveness.
    • Special environmental conditions are considered, such as:
      • Adjusting vent panel design pressure for buildings in high wind pressure areas, referencing FM 1-28 “Wind Design” standard.
      • Avoiding vent designs in snow-prone areas for buildings with roofs susceptible to snow accumulation.
  • Ventilation Design Recommendations: Vent panels should be integrated with the building’s ventilation system design to prevent secondary hazards during pressure relief.
