No. The blue flame is called the roaring flame because it makes a sort of hissing sound, it is also not called the safety flame because it emits very little light so it is a hazard. It is a hazard because you can not see it very well so it is dangerous.
Because it is 'dirty', meaning it leaves soot. Also because it isn't that hot.
The blue flame is called a roaring flame and the yellow flame is called the safety flame.
a Bunsen burner flame can be 20* to 2000*
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
The Bunsen burner was first invented by a British physicist and chemist called Michael Faraday in the early 19th century. It was than improved by a famous German chemist called Robert Bunsen in 1850. The second Bunsen burner was now safer, easier and more efficient and has an 'air hole' so you could change the flame from a safety flame (the yellow one) to a efficient flame (the blue one).
The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.
Safety flame
As a safety flame, keep it on this if the burner is not in use :)

It is often called the safety flame, (often referred to as put it on the safety flame).
The blue flame is called a roaring flame and the yellow flame is called the safety flame.
The yellow flame because that is the safety flame
In the fire
It is closed to make a safety flame.
Because even though it is safer than other flames it is still a flame and it can burn you. It is so called the "safety flame" because it is visible (yellow) and so we have a visual reminder that the Bunsen burner is burning. Compared with the usual flame (blue) which is hard to see.
The safety flame, the cold one, is wavy.
