The development of a fire compartment can be divided into four stages: initiation, growth, maturity and decline (see Figure 1).
What are the 3 stages of a fire?
stages of fire
- Ignition: Fuel, oxygen, and heat combine in a continuous chemical reaction. …
- Growth: Using the initial flame as a heat source, additional fuel is ignited. …
- Full Growth: The fire has spread to many, if not all, of the available fuel tanks, which have reached their maximum temperature, causing thermal damage.
What comes first, the smoke or the fire?
Once they start to burn, there is no smoke as the hydrocarbons turn into carbon dioxide and water (both invisible) when they burn. This explains why you don’t see smoke from the charcoal (or fire that has turned to embers).
What is the second stage of fire development?
When we go through the phases of fire, we enter the second stage: growth. Fire spread is affected by the building structure and available fuel. Growth phases are characterized by: Oxygen and fuel are sufficient to support further growth of the flame.
What is the growth phase of fire?
The growth phase occurs when the fire has started and burns itself out. We call this a permanent burn. At this point, the fire releases enough of its own heat to cause positive thermal feedback. Here the fire uses its own heat to burn the surrounding fuel sources.
What is phase 1 of the 4 key phases of fire?
The first stage – ignition (nascent)
It is extremely important to fight a fire during the training phase, as it is easiest to extinguish at this stage and causes the least damage.
What is stage fire?
- Outdoor fire pits are not permitted outside of a permanently constructed fire ring in a constructed recreation area (such as a campground or picnic area). anywhere on public land, including campgrounds.
What is the leading cause of death in a fire?

Can smoke put out fire?
If smoke comes out of the O2 fire, then yes, you can put out the fire.
Is it possible to burn firewood without smoke?
Aged wood burns much more easily in a fire and therefore wood with a low moisture content provides a cleaner burn with less smoke overall. With a moisture meter, you can determine the exact moisture content of your firewood.
