Operation precautions: airtight operation, pay attention to ventilation. The operation is as mechanized and automated as possible. Operators must undergo special training and strictly abide by operating procedures. It is recommended that operators wear self-priming filter gas masks (half masks), chemical safety glasses, rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Keep away from flammable and combustible materials. Avoid generating dust. Avoid contact with alkalis and active metal powder. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues. When diluting or preparing a solution, be careful to slowly add acid to the water to prevent overheating and splashing.

Precautions for operation: closed operation, pay attention to ventilation. Operations are as mechanized and automated as possible. Operators must be specially trained to strictly follow operating procedures. It is recommended that operators wear self-absorbing filter gas masks (half masks), chemical safety protective glasses, rubber acid-resistant clothing, rubber acid-resistant gloves. Stay away from flammable, combustibles. Avoid dust. Avoid contact with alkalis and active metal powders. Handling should be light and light, to prevent packaging and container damage. Equipped with leak emergency treatment equipment. Empty containers may contain harmful substances.
