What are the three things needed for combustion to occur what will happen if one of these is not present?

There are three components needed to start a fire: fuel, oxygen, and heat. This is commonly referred to as the fire triangle. If any one of the components is missing, a fire cannot occur.

What three things happen during a combustion reaction?

In a combustion reaction, a fuel is heated and it reacts with oxygen. The fire triangle summarises the three things needed for combustion – a fuel, heat and oxygen.

What four components are necessary to sustain combustion?

The four elements are oxygen for sustaining combustion, enough heat for raising the material to the ignition temperature, combustible material or fuel, and a subsequent exothermic chain reaction in the material.

What are the three important things needed for combustion to occur explain why?

To summarize, for combustion to occur three things must be present: a fuel to be burned, a source of oxygen, and a source of heat. As a result of combustion, exhausts are created and heat is released.

What are the three essential requirements for combustion Class 8?

There are three conditions which are necessary for combustion to take place:

• Presence of combustible substance.
• Presence of supporter of combustion.
• Heating the combustible substance to its ignition temperature.

What are the 3 ways that a fire is transmitted?

A fire spreads by transferring heat energy in three ways: Radiation, Convection, and Conduction.

• Radiation.
• Convection.
• Conduction.

What are the essential requirements for combustion?

Three things are required in proper combination before ignition and combustion can take place—Heat, Oxygen and Fuel.

• There must be Fuel to burn.
• There must be Air to supply oxygen.
• There must be Heat (ignition temperature) to start and continue the combustion process.

What are the three essential requirements?

Three essential requirements are:

• Fuel.
• Air.
• Heat to acquire the ignition temperature.

What are the three essential requirement of life?

Explanation: Life as we know it requires biogenic elements, a source of energy, liquid water, and a suitable, reasonably stable environment for evolution to take place.

What are the 3 categories of evacuation?

Simultaneous evacuation. Vertical or horizontal phased evacuation. Staff alarm evacuation (silent alarm). Defend in place.

What is the first thing you should do on discovering a fire?

Anyone discovering a fire should raise the alarm immediately, regardless as to how small the outbreak is or how innocuous it appears to be….In summary:

• Raise the alarm.
• Call the Fire & Rescue Service (999).
• Fire Marshals should check escape routes.
