Read： 560 Time：8months ago Source：Transform the World with Simplicity

Formic acid, chemical formula HCOOH, is a commonly used organic acid, in industrial production and laboratory have a wide range of applications. However, 98% formic acid is a corrosive and irritating chemical that requires extra care when used. This article will help you use 98% formic acid more safely and effectively from two aspects: correct use method and precautions.

1. Correct use

1. Wearing protective equipment: When using 98% formic acid, be sure to wear protective glasses, protective masks, protective clothing and rubber gloves. Avoid contact with skin and respiratory tract to avoid chemical burns.

2. Avoid contact with other chemicals: Formic acid has strong acidity, and alkaline substances and oxidants and other chemicals contact will produce a violent reaction, and even cause a fire or explosion. Keep these chemicals away when storing and using formic acid.

3. reasonable ratio dilution: in the experiment or industrial production need to use diluted formic acid, be sure to accurately dilute according to the requirements, to avoid the concentration is too high lead to accidents.
Precautions for
2.

1. The operating environment is well ventilated: When using 98% formic acid, it is necessary to operate in a well-ventilated environment to avoid its vapor causing harm to the human body. If the laboratory or production site ventilation conditions are not good, need to be equipped with the corresponding exhaust equipment.

2. Avoid inhaling formic acid vapor: Formic acid has a pungent odor, and prolonged exposure to high concentrations of formic acid vapor can cause headaches, nausea and other discomfort symptoms. When using to be equipped with respirator, avoid inhaling too much formic acid vapor.

3. Emergency measures: When using 98% formic acid, if it is accidentally spilled on the skin or clothing, it is necessary to rinse with plenty of water immediately and seek medical assistance. If you accidentally inhale excessive formic acid vapor, you should immediately move to a ventilated place and take first aid measures such as artificial respiration.

through the introduction of the correct use of methods and precautions, I believe everyone has a clearer understanding of the use of 98% formic acid. Although chemicals have made great contributions to the development of human society, they must strictly abide by the relevant safety operation procedures and do a good job in safety protection. I hope everyone can use 98% formic acid safely in work and study to avoid accidents.
