Toxic Gases in a building fire
A small fire, growing from wall socket due to electrical false will grow into a larger fire. Temperatures rise up from hundred degree to 200-600 degrees in 4 second. That is a situation where we called “Flash Over”. It means that room is now filled with toxic gases. Some of them can be ignited and exploded. People in the building still not move. They are too busy to react to fire alarm.

What will you do if you hear gun fired in shopping mall? Do not laugh at my question. This is my suggestion, STOP, DROP, and HIDE.
