Ether is an extremely effective solvent for many chemical reactions but is extremely dangerous. First and foremost, ether is extremely flammable. In enclosed environments, ether can also exhibit certain explosive properties (explosions in meth labs are often the result of the use of ether solvents and poor ventilation). Many ether solvents will degrade to a peroxide form which can be extremely volatile. Expired casks of ether must be treated very carefully (bomb-squads are often called upon to dispose of expired ether kegs at chemistry labs). Ether also has psychoactive properties which for many years were utilized by the medical community as a general anesthetic. In general, ether must only be used in extremely ventilated environments with proper fire safety devices.
it is highly flamable

as this an obvious answer let me answer it in brief. chemicals are :- poisons , explosive , dangerous, can give out a lot of heat etc.
Yes, caustic soda does clean toilets and also removes limescale. However, you must be very careful when using it and make sure that it does not get on your skin. You must also make sure that you do not mix it with any other chemicals or cleaning agents.

Any special precautions; you must be careful when working with strong acids or bases, very inflammable and volatile compounds, toxic liquids, radioactive liquids, explosive liquids, etc.

Because it is a substance that has extreme physical hazards cognisance of which must always be a priority when planning even the simplest of procedures and the use of best laboratory practice at all times is paramount in ensuring its safe use.

Extremely cold, and displaces oxygen from the air.
you can burn yourself or burn someone else. you must always be careful.
The major disadvantage of using ether as an extracting solvent is that it is very flammable. It also oxidizes into an explosive in some cases, is an anesthetic, and is very vapor dense (meaning it will fall to the floor and move around there).
Yes. Scamming on the internet is very common. You must always be careful.
Yes, which means you must be careful when using it. One can die by heart attack from plastic surgery
