Fire & Safety
Overview
Each year, more than 4,000 die and more than 25,000 are injured in fires, many of which could be prevented. Direct property loss due to fires is estimated annually at $8.6 billion of India.
To protect yourself, it is important to understand the basic characteristics of Fire.
Fire spreads quickly: There is no time to gather valuables or make a phone call. In just two minutes, a fire can become life-threatening. In five minutes, a residence can be engulfed in flames.
Heat and smoke from fire can be more dangerous than the flames. Inhaling the super-hot air can sear your lungs. Fire produces poisonous gases that make you disoriented and drowsy. Instead of being awakened by a fire, you may fall into a deeper sleep. Asphyxiation is the leading cause of fire deaths, exceeding burns by a three-to-one ratio.

Fire Triangle
Understanding the "Fire Triangle" is the most basic concept in Fire Prevention and Control. In order for any fire to occur, three critical elements must be present:
- A fuel or combustible material
- An ignition or heat source
- Oxygen in sufficient quantities to support combustion.
When all three of these elements come together, combustion is the result. However, if only one of these elements is removed from contact with the other two, the threat of fire can be minimized. Thus, if oxygen, heat or the fuel supply can be removed, there is minimal risk of fire.
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
Essentially, fire extinguishers put out fire by taking away one or more elements of the fire triangle/tetrahedron.
- Fire can truly be called the mother of all civilisation. It was the discovery of fire and the numerous uses to which it was put that has contributed directly or indirectly to the advancement of civilised society as we know it today
- The invention of tools & tool-making technology, cooking & nutrition, medicinal & health sciences, construction & transportation, defence & protection, all have their genesis in the energy & power that fire provides
- The earliest source of heat & light for the very origin of life on earth was the Sun, a giant ball of burning hydrogen, in other words, fire!
- One thing is certain. Fire has probably been used since much earlier times
- We can imagine the stages in its history: from the time hominids discovered charcoal which had caught light accidentally in a natural fire to their keeping the smoking coals; from carrying burning coals on long journeys to lighting fires whenever they were needed
- Ancient Greeks believed that it was Prometheus who brought fire to the mortals by stealing it from the Gods, thus earning him the wrath of Zeus
- For Zoroastrians, fire was a gift of truth, order, and righteousness
- For Hindus, fire is Agni, the God that purifies
- In that sense, the possession of fire is the possession of knowledge.
Three Stages of Fire
Ignition
When the fire outbreaks with heat , smoke and spark and the portable fire fighting fire extinguishers need to be used immediately in effective way
Critical
When the fire is growing , cannot be contained and spreading fast and the fixed installation of fire fighting like Sprinkler systems and fire hydrants can be used
Blaze
When the fire is uncontrollable and only professional help of Fire Brigade is needed
What to do During a Fire
If your clothes catch on fire, you should use SDR Principle
- Stop, Drop, and Roll - until the fire is extinguished. Running only makes the fire burn faster
- Crawl low under any smoke to your exit - heavy smoke and poisonous gases collect first along the ceiling
- Close doors behind you as you escape to delay the spread of the fire
- Stay out once you are safely out. Do not reenter. Call 101
Classification of Fuels:
Not all fuels are the same, and if you use the wrong type of fire extinguisher on the wrong type of fuel, you can, in fact, make matters worse. It is therefore very important to understand the four different classifications of fuel.
Escaping the Fire

- Make sure windows are not nailed or painted shut. Make sure security gratings on windows have a fire safety opening feature, so they can be easily opened from inside.
Classification of Fuels
Not all fuels are the same, and if you use the wrong type of Fire Extinguisher on the wrong type of fuel, you can, in fact, make matters worse. It is therefore very important to understand the four different classifications of fuel.
Class A Fuels Wood, paper, cloth, trash, plastics and solid combustible materials that are not metals.
Class B Fuels Flammable liquids: Gasoline, oil, grease, acetone or any non-metal in a liquid state.
Class C Fuels Electrical: Energized electrical equipments, as long as it's "plugged in," it would be considered a class C fire.
Class D Fuels Metals: Potassium, sodium, aluminum and magnesium.
