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



Fully Developed


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)
