Wear goggles and don't sit down, not letting your clothes catch fire is another good idea. No why given.
You have to relight the Bunsen Burner every time you use it.
This is not a very well worded question. What do you mean by why should it be used? I Bunsen burner is used for heating things, usually in a lab setting.
Bunsen burners are a fire hazard and should not be left unattended. However, accidents can occur even when the burner is off. Check the tubing connecting the gas line to the burner to be certain there are no cracks and it is secure. If the tubing is dislodged and the gas line valve is not off, gas will fill the room creating a potential explosion situation. This has happened. There are safer alternatives to the classic Bunsen burner. A Flame Boy or a Touch-o-matic burner eliminates the issue of a constant flame. A bacticinerator can be used to sterilize plating loops. There are also glass bead sterilizers that may be used.

The flame on a Bunsen burner should be blue when not in use. If the flame is yellow, it may indicate a problem with the burner, such as not enough air mixing with the gas, which can be a safety hazard.
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
It should be placed on a Safety Heat Proof Mat on to a gauze and then on to a tripod.
You should not use a Bunsen burner inside a lab when there are flammable materials nearby that could ignite or if there is poor ventilation that could lead to a buildup of fumes. Additionally, if the lab does not have proper safety equipment in place, it is not advisable to use a Bunsen burner.

The Bunsen burner should be left on a low flame to prevent accidents. It should be adjusted based on the specific experiment being conducted to ensure the desired heat level is maintained.
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.
You should turn off the Bunsen burner between experiment setups to prevent accidental fires or injuries, as well as to conserve gas and ensure safety in the laboratory environment.
Nothing much really. Just don't touch the flame, wear goggles and that's all. Using a safety mat is unnecessary and it doesn't really matter if you keep the airhole at the base open or closed.
You can boil mercury from a Bunsen burner. Mercury has a low boiling point of 674 degrees Fahrenheit, making it possible to vaporize it using a Bunsen burner's high heat. However, it's important to note that working with mercury can be hazardous, so proper safety precautions should be taken.
A lit Bunsen burner should never be near alcohol because alcohol is flammable and highly combustible. If the alcohol were to accidentally catch fire from the Bunsen burner, it could cause a dangerous and uncontrollable fire. It is important to always follow proper safety protocols and keep flammable substances away from open flames.
