in SSCP
In the Sybex 7th edition phsical security chapter it is written that:
The four primary stages of fire
Stage 1: The Incipient Stage At this stage, there is only air ionization but no smoke.
Stage 2: The Smoke Stage In Stage 2, smoke is visible from the point of ignition.
Stage 3: The Flame Stage This is when a flame can be seen with the naked eye.
Stage 4: The Heat Stage At Stage 4, the fire is considerably further down the
timescale to the point where there is an intense heat buildup and everything in the area
burns.
Fire extinguishers are to be used only when a fire is still in the incipient stage.
Is it correct or mistakenly wirtten sentence? Don't we use fire extinguishers in other stages? What does this mean?

After the incipient stage, you should call the fire department. We are not firefighters, so our involvement with fighting fires should be minimal.

Good explanation but a little bit hard to infer that meaning. By the way, thanks for your answer.

If you search incipient stage of fire you will see it means a small fire that has just started.
sybex is wrong as they are many times.
What they mean is that you should fight small fire at initial stage ONLY.
Incipient – This first stage begins when heat, oxygen and a fuel source combine and have a chemical reaction resulting in fire. This is also known as “ignition” and is usually represented by a very small fire which often (and hopefully) goes out on its own, before the following stages are reached. Recognizing a fire in this stage provides your best chance at suppression or escape.
