Yes it is.... When lighting it up... in order to not experience a strikeback.... <--- Google that... Then when it is litted you can turn the collar to make the air hole open and get a non luminous flame :))
it's because the flame will roar up and can burn you.
You need to close the hole and plug it into the gas point then light the match and then turn on the gas, to make the flame hotter open the hole.Note: do NOT light the Bunsen burner next to flammable substance
To change the flame of a Bunsen burner you must open or close the air valve, usually this is done by rotating the barrel.
See the figure at thge link below.
A normal Bunsen burner has a chimney which contains gas, a collar to adjust the air hole, a air hole that will leak gas, a gas tap that provides gas to the burner and the rubber tubing leads gas to the burner.
A Bunsen burner is a device that is used to heat materials in science. It uses a flow of gas and an air hole to regulate the temperature of the flame.
With the air hole fully open, the flame will be fierce, but I doubt if it can be said to be dangerous. Simply close the air hole a little.

when you light up the burner you should see that the Bunsen burners air hole is closed that is the safest flame
The function that covers the air hole in a Bunsen burner is the collar.
The parts of a Bunsen burner has collar,base.air hole and barrel. Collar : Adjust size of air hole Base: Support Bunsen Burner Air hole: Allow air to enter air hole Barrel:To ensure the flame is adjusted to a suitable position
The air hole in a Bunsen Burner allows air to mix with the gas prior to burning so that the flame can be adjusted as desired.
it's to prevent a strike-back
A Bunsen burner flame is hottest when the air valve hole is open.
The parts of a Bunsen burner include: the barrel, gas hose, base, collar, air hole and gas flow valve. The Bunsen burner is a small adjustable gas burner that is mainly used in scientific laboratories.
You need to close the hole and plug it into the gas point then light the match and then turn on the gas, to make the flame hotter open the hole.Note: do NOT light the Bunsen burner next to flammable substance
To change the flame of a Bunsen burner you must open or close the air valve, usually this is done by rotating the barrel.
By using the correct ratio of oxygen and fuel mixture. Opening the air hole in the Bunsen burner increase the oxygen which helps the flame burner hotter .
