What is acetone
Acetone has the simplest structure in the classification of ketones. It is a substance that is used as an organic solvent for various purposes because it is small in molecule and easily soluble in water and most oils and fats.
Uses of acetone
Because both hydrophilicity and lipophilicity are available, it can be used for various purposes.
For example, women have a familiar light remover to remove nail polish. Manicure = ideal for removing paint.
However, since the oil of the hand is melted and dropped together, it is heard that it is easy to dry.
Acetone may also be used for car and motorcycle maintenance. It plays a role in removing oil stains.
In addition, it is used to make samples by degreasing living things (dropping oil), to wash laboratory equipment, and to mix solvents that do not mix with water.
Acetone danger, acetone toxicity
Strict ban on fire (Fire Service Act: Dangerous Goods Class 4 1st Petroleum Water-soluble)
Acetone has a flash point of -20 ° C, which is flammable even at room temperature. Furthermore, it is highly volatile, so be sure to ventilate it before using it after using it.
In Japan, it is also designated by the Fire Service Act, and storage exceeding the specified amount requires notification to the fire department.
Care must be taken because there must be a Dangerous Goods Otsuka IV or a person with a Class A license.
Hazard
Acetone is designated as a second-class organic solvent in the organic solvent poisoning prevention regulations in Japan and is considered highly toxic.
Therefore, when dealing with acetone above a certain concentration, it is necessary to take various legal measures.
For example, you must put on special protective equipment, arrange ventilation facilities, regularly measure the acetone concentration in the workplace, and have workers undergo special health examinations.

住宅施工業者が、改修工事後に養生テープを剥がしたら、床のワックスの一部が一緒に剥がれて‟部分剥離”してしまい、ダメージ部分と非ダメージ部分との間に‟色具合の差”や‟僅かな段差”などの不具合が生じてしまいました。業者は「アセトン洗浄して床面全体をきれいにした後で、水性ワックスを塗って原状回復したい」と言っていますが、この方法は有効でしょうか？（業者は一応、部分的なパッチテストみたいなことをして「結果は良好だった」と言っています）。引火性や有毒性も高いようなので、ちょっと心配しています。一般住宅の床面全面をアセトン洗浄するときの‟注意事項”などがありましたら、ご教示ください。（作業中の注意もさることながら、将来の‟ワックス塗り直しメンテ”時の注意事項にも興味を持っています。）よろしくお願いいたします。
