Note:

Fire Hazard Risk Calculation (Fire Load Density ) is a key indicator of fire hazard risk. It represents the amount of heat energy that can be released per square meter of floor area if all combustible materials in a space catch fire. Understanding FLD helps assess fire safety levels and determine necessary fire prevention measures.

Why is FLD Important?

FLD is crucial for fire risk assessment as it helps categorize spaces into low, moderate, high, or extreme fire hazard zones. A higher FLD indicates a greater fire hazard, requiring stronger fire protection measures.

Understanding the Parameters:

• Mass of Combustible Material (kg): The total weight of flammable substances present, including wood, paper, plastic, textiles, and chemicals.
• Heat of Combustion (MJ/kg): The energy released when one kilogram of a material burns. Different materials have varying heat values, affecting the total fire load.
• Floor Area (m²): The total surface over which the fire load is distributed. A larger floor area lowers the FLD, while a smaller area increases it.

How to Use the FLD Calculator:

1. Enter the number of different combustible materials in your area.
2. Click the "Set Materials" button to generate input fields.
3. For each material, enter:
   • Mass (kg): The weight of the material.
   • Heat of Combustion (MJ/kg): The energy released when it burns.
4. Enter the total floor area (m²) of the space.
5. Click the "Calculate FLD" button to get the fire load density.
6. Check the result and refer to the FLD risk level for necessary fire safety actions.

Interpreting FLD Results:

• ✅ Low Risk: Safe fire load density, minimal fire hazard.
• 🟡 Moderate Risk: Requires periodic fire safety checks.
• ⚠️ High Risk: Demands strong fire prevention measures.
• 🔥 Extreme Risk: Immediate fire safety action required.
