1. Never heat alcohol directly on naked flame
2. you should take a beaker with boiled water in it and then place the alcohol with the test tube in it
3. you should wear goggles while heating alcohol.
4. never smell the alcohol directly after heating
Yes. It can cause an explosion of vapor, and fire. Alcohol should be heated in a water bath, and the temperature of the water should be carefully monitored.
Donβt heat an alcohol
The precautions that must be taken when heating alcohol are that alcohol must not be heated directly. When heating alcohol, it must always be placed in a beaker of water.
Explanation:
Alcohol on burning changes into carbon dioxide and water. The release of carbon dioxide on heating is not good and therefore alcohol must not be heated directly.
When alcohol is heated using a beaker of water, it will evaporate slowly giving alcohol vapour. The heating of alcohol in this way is a physical change whereas when alcohol is heated directly, the change is a chemical change.

to control the fire
The alcohol is cooked of and loses density in the liquid. Because the liquid becomes less dense, the mass goes down. (Unless you are talking about pure alcohol)
Wear safety goggles, the vapours may go in your eyes and he harmful. Do not touch the hot liquid, for obvious reasons.
There is no indication in the question as to how much alcohol is being used. Assuming a large volume, I suggest the following: As alcohol is a flammable liquid that gives off fumes, the main precautions are: no naked flames, and work in a well ventilated area. Other precautions would be to wear surgical gloves, and goggles for eye protection from splashes. A foam fire-extinguisher nearby is a sensible precaution too.
tongs
The precautions are -wire gauze should be placed in between the flask and tripod stand while heating process.clamp the flask gently in the retort stand.

The alcohol lamp is generally used during excursions, but can be used sometimes in a laboratory for heating when another source of heating is not available. Alcohol is the fuel for heating.

Heating something
It is called stilling it is when alcohol is changed to ethanol by heating and cooling the alcohol
The separation of alcohol from a fermented liquid is by heating it until the alcohol vapourises and then condenses into liquid again.
