S AFTEY R ULES Make sure the gas is turned off before setting up the Bunsen burner. Make sure you have got all the equipment you need before you turn it on. Always wear safety goggles. Never enter the lab without an adult. Proceed with caution whenever a Bunsen burner is a light. Make sure the gas works properly. If there is a gas leak tell someone immediately. You are never to be in the science lab alone. Click the flame to go back to the contents.

T HE D O ’ S AND DON ’ TS OF A B UNSEN B URNER A REA. Do not play practical jokes or silly behaviour in the laboratory. Never run in the laboratory. The performance of unauthorized experiments is strictly forbidden. Do not sit on laboratory benches. Keep work area neat and free of any unnecessary objects. Thoroughly clean your laboratory work space at the end of the laboratory session. Do not block the sink drains. Click the flame to go back to the contents.

S ETUP OF A BUNSEN BURNER. When you first arrive in the laboratory the gas will be turned off at the mains. Your teacher will turn the main gas tap on once all of the Bunsen burners have been set up correctly. The Bunsen burner has rubber tubing attached to it. The other end of the rubber tubing needs to be firmly attached to the gas tap on your bench. It is very important that you check this tap is in the 'off' position before you attach your Bunsen burner. Ask your teacher to check that your Bunsen burner is correctly attached to the gas tap and ready to light (air-holes closed). Once your teacher has checked all of the Bunsen burners he will turn on the main gas supply. Lighting the Bunsen burner When you light a match always strike it away from you. Make sure that your match is alight before you turn your gas tap to the 'on' position. You will need to press the gas tap down before you turn it. As soon as the gas tap is open place your lighted match about five centimetres directly above it. The Bunsen will light to give a yellow safety flame. Click the flame to go back to the contents.

H OW T O LIGHT A BUNSEN BURNER. The first step is to check for safety - lab coat on, long hair tied back, safety glasses on, books and papers away from the flame, apparatus set up not too close to the edge of the table... The second step is to look at the holes. Check that the closed. The holes can be adjusted to let in more or less air by turning the collar (see photos below). Wait for the teacher's permission, then light the match. Some people prefer to turn the gas on and light the match after. The problem is, if the match breaks or goes out, the gas is leaking out of the tap while you get a new match. Adjust the flame by turning the collar so that you have the appropriate flame for the experiment (usually the medium blue flame). During the experiment, stay vigilant so that if a problem occurs, you are ready to turn off the flame quickly. This means that you should not leave your table unattended.
