When using acids, remember to wear an apron

Always wear safety goggles Always tie long hair back

The Bunsen burner is used in laboratories to heat things.   In order to use it safely and appropriately, it is important to know the correct steps on how to set it up and operate it.  A Bunsen burner can produce 3 different types of flames:

One of the flames is a yellow / orange colour.  It is approximately 300°C.  It is never used to heat anything, only to show that the Bunsen burner is on.  It is called the safety flame

The medium flame, also called the blue flame or the invisible flame is difficult to see in a well-lit room.  It is the most commonly used flame. It is approximately 500°C.

The hottest flame is called the roaring blue flame .  It is characterized by a light blue triangle in the middle and it is the only flame of the 3 which makes a noise.  It is approximately 700°C.

Robert Bunsen was a German scientist .He specialized in the field of organic chemistry and spectroscopy .He invented one of the most commonly used sources of heat in laboratory's ,the bunsen burner .Most heat sources of his time (mid-1800’s) were smoky and inefficient . He found that by allowing gas and air to mix ,the flame would result in no smoke and very high temperatures ( ideal for laboratory use .
