Fire Safety Awareness: Fire Prevention

In previous two blogs, we have discussed a topic like basic chemistry, fuel properties, flammability principles, fuels behaviours in combustions and classification of fires. Getting knowledge of all these things is base for understanding fire prevention concept and practise them in our day to day life to avoid losses due to accidental fire at our home or at our workplaces. If we understand the flammability principle, fuel properties and fuel behaviours then Fire prevention is not an impossible task to perform and practice in our day to day life. Lets we start understanding the concept of prevention with the help of fire triangle. let’s start

Fire Triangle :

Fire prevention technics
Three necessary elements to start a fire

The fire triangle (which is also known as the combustion triangle) is a simple model for understanding the chemical reaction which must occur to create a fire. It is composed of three elements – fuel, heat and oxygen – which must all be present for a fire to ignite. It also demonstrates the interdependence of these ingredients in creating and sustaining a fire and teaches us that removing any one of these elements would prevent or extinguish the fire. Then what should we remove or isolate first Heat? Fuel? Air?. Don’t get confused, remove the easiest you can. Then what is the easiest ?.  for you must know the sources of ignitions, potential sources of fuels, factors bring these three elements together and practises that can affect the prevention success

Sources of Ignitions :

At your home and workplaces, there are numerous sources of ignition available which can accidentally lead to the fire incidents. Proper maintenance, proper handling and proper security of these sources can prevent fire. ignition sources can be of various type and nature lets see

Chemical heat Energy:

  • Heat of Combustion
  • Spontaneous Heating
  • Heat of Decomposition
  • Heat of Solution

Electrical Heat Energy:

  • Faulty / Non-Standard Electrical equipment
  • Resistance Heating
  • Di-electric Heating
  • Induction heating
  • Leakage Current Heating
  • Heat from Arching
  • Static Electricity Heating
  • Heat Generated by Lightening

   Mechanical Heat Energy:

  • Frictional Heat
  • Friction Sparks
  • Heat of Compression

Others Sources:

  • Smoking
  • Storing of incompatible materials together

Forms and Types of Ignitable Materials (Fuels):

  • Building Materials, Contents & Furnishings
  • Stored material and supplies
  • Trash, lint and dust
  • Combustible or flammable gases or liquids
  • Volatile Solids

Factors that bring Heat and Ignitable material together :

  • Arson
  • Misuse of Heat Source, ignitable material
  • Mechanical / Electrical failure
  • Design, construction or installation deficiency
  • Error in Operating equipment
  • Natural Causes
  • Exposure

Practices that can affect Prevention Success :

  • Housekeeping
  • Security
  • Education of occupants
  • Control of fuel type, quantity and distribution
  • Control of heat energy sources
