By this I'm thinking your talking about a Bunsen burner? A flame should never be left unattended. You should have someone supervise it while you go or if this isn't a possibility then turn it off and then once you return put it back on. If none of this are possible turn the flame down onto a low heat ( i think it is a yellow flame) and make sure nothing around it can catch on fire/ no one else could knock it over.
Shut off the gas and let any free gas clear out. The next thing you should do is check the lines to see if there is a leak. Next, check to see if the knobs controlling the air inlet and gas inlet are correct. If the air inlet is closed, there will be no combustion and no flame. Same goes for the gas inlet. Fiddle with these until you have the flame desired. If this does not fix the problem of the burner going out, try a different one.
You have to be wearing safety goggles and apron or lab coat, and no loose fitting clothes. Do not wear cloths that are made of synthetic that easilly catch fire. Cotton and wool are preferred materials for clothing.
Check the rubber tubbing for rips and tears and replace if there are any. Know where the nearest fire extinguisher is. Know where the safety shower is and how to use it. Don't fool around.
Also, never leave a lit Bunsen burner unattended.
well there is alot of them
be careful
turn the gas on
make sure there is no cracks in the gas tube
make sure you are weiring in a fireproof bench
keep stuff away from it
before turning on the gas light a match/spilnt and hold it to the bottom on the chimney of the bunser burner
tuck tie in and take blazers of
where safety goggles
and alot more than you
Ice begins to melt when its temperature reaches 0 degrees Celsius (32 degrees Fahrenheit), transitioning from a solid to a liquid state. When exposed to a Bunsen burner, the heat from the flame will increase the temperature of the ice, causing it to melt more rapidly.
Yellow safety flame - Safe becasue you can see it easily and know it is there. Not used for heating because it creates soot.Silent blue flame - Used to for gental heating and is silent and not very visible.Roaring blue flame - Strongest heating setting and is made of two cones. The outside cone is the flame and it is blue , the inside cone is unburned gas that is purple.All credit goes to another user to wrote this on a different conversation.
Funtions of the Bunsen burner: air-hole: to control the amount of air let into the Bunsen burner for combustion. barrel: To allow the flame to beat a suitable height for burning. base: To support the Bunsen burner so that it will not fall over. collar: helps to adjust the gas being produced gas tap: to store gas. jet: To allow gas to enter the Bunsen Burner ( by helpingppl) Flame: the one part you don't want to forget
In a Bunsen burner with a blue flame, the ratio of oxygen to gas is approximately 1:3. This means that for every molecule of oxygen, about three molecules of gas are present in the mixture. This ratio allows for complete combustion of the gas, resulting in a clean, blue flame.
The chimney or barrel on a Bunsen burner is used to control the air flow and regulate the flame. By adjusting the opening of the chimney, you can control the amount of air that mixes with the gas, which in turn affects the type of flame produced.
When a Bunsen burner is open and operational, the flame is usually blue. When the Bunsen burner is closed or turned off, the flame typically goes out and there is no color.
Little/none
The mat that goes on top of a Bunsen burner is called a wire gauze. It is used to distribute the heat evenly and protect glassware from direct contact with the flame.
To put out a Bunsen burner, simply close the air vent to cut off the oxygen supply first, then turn off the gas supply using the valve on the burner. Never use water to extinguish a Bunsen burner as this can spread the flame.
As you slowly turn off the gas on a Bunsen burner, the flame will decrease in size and intensity until it eventually extinguishes. This is due to the reduction in the flow of gas, which leads to less fuel available to sustain the combustion reaction.
To regulate the size of a flame on a Bunsen burner, twist the collar on the base of the burner to control the air intake. Opening the air hole wider will result in a larger, more intense flame, while closing it will create a smaller, more controlled flame. Adjust the collar until you achieve the desired flame size.
how to be safe using a Bunsen Burner:1. never leave the flame unattended... especially when on the blue flame.2. always wear safety glasses.3. don't heat up anything metal because they will get very hot.4. don't let young children near the Bunsen burner when it's on.5. always have someone watch it.6. turn the gas off immediately when the flame goes out.
Wear Safety Goggles Do NOT Touch The Element If The Flame Goes Out Turn Off The Gas Immediately
The Bunsen burner goes under a thin, fireproof chemistry table.
