Question 227Safety & Environmental - Assistant Engineer

The correct answer is D) electricity. The fire triangle consists of three essential elements required for a fire to occur: fuel, oxygen, and heat. Electricity is not one of the three elements that make up the fire triangle. While electricity can act as an ignition source and provide the heat necessary for a fire, it is not considered a fundamental component of the fire triangle itself. The other answer choices (A, B, and C) are all part of the fire triangle. Fuel provides the combustible material, oxygen supports the combustion process, and heat is the source of ignition that initiates the chemical reaction between the fuel and oxygen.
