Fire Point and Flash Point of Flammable Materials

Published by GayaMadhusanka on

There are different types of flammable materials. As you know liquids, gases, chemicals, and powders are some flammable material forms. However, fuels, other industrial liquids, and some engineering materials are common flammable materials. Understanding the fire point and flash point of flammable materials is vital for fire safety, storage, and handling procedures.

Here we will discuss what are the fire, flash, and self-ignition points of materials. This article will help you to find some common material fire and flash points as well.

What is Fire Point?

The Fire Point refers to the temperature at which a substance emits enough vapors to sustain combustion when an external ignition source is present. It is the temperature at which a material will continue to burn after being ignited. At the fire point, the substance releases enough flammable vapors to sustain a fire.

What is Flash Point?

The Flash Point is the lowest temperature at which a substance’s vapors can ignite when exposed to an open flame or an ignition source. It represents the point at which vapors emitted by the substance can briefly catch fire but may not sustain combustion. The flash point is an important safety parameter, as lower flash point liquids present a higher fire risk.

Fire and Flash Point for Common Fuel

This chapter will give you a data set of fire and flash points of fuel and other industrial common-use materials. However knowing these data will give you an idea about flue storage requirements, transportation requirements,s and handling safety conditions as well.

Fire and Flash Point of Common Fuel

When you are dealing with fuels you should have an idea about the fire and flash point of the fuels.

Diesel Fuel5212664147
Jet Fuel (Jet A)3810049120
Natural GasN/AN/AN/AN/A

Wood as a Fuel?

When considering wood, it is an engineering material and sometimes it is a fuel. There are different types of wood. Industrial furnaces, boilers, and heaters are the some of applications of wood as fuel. Depending on the fuel types, humidity level, and water content of the wood these fire and flash points will be changed.

Natural Gas Fire and Flash Points?

Natural gas is a gas and does not have flash points or fire points.

Other Flamble Materials

Other than fuels there are some common flammable materials that are used in the industry.

What is Self Ignition Point?

The Self-Ignition Point refers to the temperature at which a substance can ignite spontaneously without an external ignition source. Simply you do not need to ignite. But this is a very critical situation because some accidents can happen. Because of this, some materials have specific storage, transportation, and handling procedures. As an example, always petrol store in the underground to mitigate the self-ignition.

How Self Ignition Occurs?

It occurs when the substance undergoes a chemical reaction, producing enough heat to reach its ignition temperature. This is a critical parameter, especially for materials that may gradually release heat or undergo exothermic reactions, as they can potentially ignite under certain conditions. Understanding these points is essential for fire safety. However It helps in determining suitable storage, handling, and transportation procedures to ensure safety.

Self-Ignition Points of Common Fuels

The followings are some common self-ignition points for coom fuels

  • Gasoline/Petrol: Approximately 495°C (923°F)
  • Diesel Fuel: Approximately 210°C (410°F)
  • Jet Fuel (Jet A): Approximately 210°C (410°F)
  • Kerosene: Approximately 220°C (428°F)
  • Propane: Approximately 470°C (878°F)
  • Butane: Approximately 365°C (689°F)
  • Methanol (methyl alcohol): Approximately 385°C (725°F)
  • Ethanol (ethyl alcohol): Approximately 365°C (689°F)
  • Natural Gas: Approximately 540°C (1,004°F)

You can avoid the above temperature point from the above fuels during transportation and storage. Then it will prevent self-ignition.
