The fire is very difficult to control. This is extremely hot, nearly red hot. The room will carry on burning until it has consumed all the fuel, or until firefighters put it out. Since fires grow so fast and become deadly so quickly, it is important that we detect them early. There are a number of different ways to detect a fire.
Smoke detectors look for the reduction in visibility caused by sooty gases.
Instead, they may be able to detect the small charge that exists on smoke particles. In the home, a smoke alarm is the best way to detect a fire. A smoke alarm will detect a fire when it is still very small. It will sound a loud noise to wake up the family if they are asleep. It could be set off by steam, so don't put smoke alarms in bathrooms or kitchens.
