Benzoic acid, also known as benzoic acid, is a commonly used organic chemical reagent, which is widely used in medicine, chemical industry, food and other fields. However, due to its strong corrosiveness and irritation, special attention should be paid to safety when using it. The following are the correct use methods and precautions for benzoic acid.

1. safe use of benzoic acid method
1. wear protective equipment: use benzoic acid should wear protective glasses, masks, gloves and other protective equipment, avoid direct contact with the skin and respiratory tract.
2. Keep away from fire: Benzoic acid is flammable, so keep away from fire sources when using it. It is strictly forbidden to operate near flammable materials.
3. Ventilation environment: In the process of using benzoic acid, a good ventilation environment should be maintained to avoid poisoning caused by long-term retention of vapor.
4. to comply with the operating procedures: in strict accordance with the use of benzoic acid instructions and operating procedures for operation, to avoid accidents.

2. of benzoic acid storage precautions
1. storage environment: benzoic acid should be stored in a cool, dry, ventilated warehouse, away from fire and heat sources.
2. Storage container: Choose a storage container with good corrosion resistance to avoid mixing with other chemicals.
3. Mixed storage is strictly prohibited: Benzoic acid is an organic acid, and it is strictly prohibited to mix with alkali, oxidant, reducing agent and other chemicals.
Precautions for the treatment of
3. benzoic acid
1. Dissolution treatment: Benzoic acid will generate reaction heat during the dissolution process. Attention should be paid to controlling the dissolution speed to avoid splashing and causing damage.
2. Waste treatment: The used benzoic acid shall be classified, packed and transported according to the regulations on hazardous waste treatment, and shall be handled by professional units.

emergency measures for 4. benzoic acid
1. eye contact: if you accidentally splash benzoic acid into your eyes, you should immediately rinse with plenty of water and seek medical attention.
2. Skin contact: If benzoic acid is accidentally splashed on the skin, rinse immediately with plenty of water, and immediately remove contaminated clothing and footwear.
3. Inhalation poisoning: If inhalation poisoning occurs when using benzoic acid, you should immediately stay away from the scene, keep the respiratory tract unobstructed, and seek medical treatment immediately.
4. poisoning by mistake: if you eat benzoic acid by mistake, you should drink plenty of water immediately and seek medical treatment immediately.

5. the use of benzoic acid contraindications
1. Prohibit excessive contact: Prolonged contact with benzoic acid will cause harm to the body, especially to the skin and respiratory tract.
2. Prohibit mixed use: Benzoic acid mixed with alkali, oxidizing agent, reducing agent and other chemicals will produce violent chemical reaction, leading to accidents.

6. of benzoic acid emergency treatment measures
1. When an accident occurs, the first time should be quickly evacuated from the scene, cut off the fire source, maintain ventilation, fire emergency treatment.
2. In case of injury caused by human contact with benzoic acid, wash the skin or eyes with plenty of water immediately and carry out first aid treatment.
3. After the leakage of benzoic acid, it should be immediately absorbed with dry sand, wet soil or fire foam, raked with anti-static tools, and properly handled.

7. of benzoic acid waste treatment
1. benzoic acid waste should be classified, packaged, transported and treated by professional units.
2. It is strictly forbidden to dump at will to avoid pollution to the environment.

To sum up, benzoic acid is a kind of organic acid chemicals. When using it, you need to be extra careful and follow the correct use methods and precautions to ensure safe use. When using and storing benzoic acid, it is important to follow the relevant regulations and guidelines to ensure the safety of people and the environment. Benzoic acid, as an important organic reagent, can provide better help for experiment and production only if it is used correctly.
