Eco SafeTech is providing the fire loading procedure of a building or compartment in such a way of establishing the potential severity of a hypothetical future fire. The heat output per unit floor area, often in kJ/m2, calculated from the calorific value of the materials present for evaluating industrial safety risks.
Fire load is a useful in determining the growth and severity of fires. The mass of the material is calculated in kg. The calculated mass is multiplied by its calorific value in MJ/kg to get fire load. The calculated valve is then divided by area of the floor to give fire load density.
Fire loading calculations formula:
qc =∑ mvHv / Af, Where qc = fire load (MJ/m2), Af= Floor area (m2),
mv= Total mass of the combustible material (Kg) and Hv= Calorific value of the combustible material (MJ /Kg)
How much material in a Building- How well it is Burn
Types of Fire Loads:
There are two types of fire load.
Movable Fire Load: Which is also termed as content fire load.
Fixed Fire Load: Which is also termed as non-movable or permanent Fire Load.
Four Stages of Fire Load
Ignition
Growth
Fully Developed
Decay
Classification of Fire
Class A Fire
Involves Organic combustible materials e.g., water, foam, halocarbons.
Class B Fire
Involves Flammable liquids, liquefiable solids.
Class C Fire
Involves Flammable and liquified Gases.
Class D Fire
Involves metal fires (Magnesium, Potassium, Sodium, Zinc)
