What to pay attention to when cleaning chemical storage tanks

Cleaning chemical storage tanks is a high-risk task that requires strict adherence to safe operating procedures and relevant laws and regulations. The following are several aspects that need to be noted:

1. Stability check: Before starting the cleaning process, it is necessary to conduct a stability check on the storage tank. The storage tank should be free of residual chemicals, harmful gases, or other hazardous substances, and the tank should be inspected for cracks, corrosion, or other damage.

2. Protective equipment: When cleaning storage tanks, appropriate personal protective equipment must be worn, including chemical goggles, respirators, protective clothing, and gloves. All protective equipment complies with relevant standards and has been properly used and maintained.

3. Gas detection: Before entering the storage tank, use a suitable gas detection instrument to detect the air. The measurement index meets the stability standard and there are no flammable gases, toxic gases, or oxygen deficiency phenomena.

4. Ventilation system: Adequate ventilation system must be in operation during the cleaning process. The ventilation system should be able to promptly remove residues and harmful gases released from the storage tank to maintain a stable working environment.

5. Tank cleaning: Select appropriate cleaning methods and cleaning agents based on the characteristics of the residues inside the tank. Follow the relevant regulations on chemical management and waste disposal, and properly dispose of the waste liquid and waste after cleaning.

6. Work Plan: Develop a detailed work plan that all participants understand and comply with. Include workflow, protective measures, and emergency situations in the plan to minimize risks to a greater extent.

7. Emergency response measures: During the cleaning process, emergency response measures must be established and training must be provided to all participants. Including escape routes, emergency shutdown procedures, first aid measures, etc.

8. Training and Qualification: All personnel involved in tank cleaning are trained and qualified. Including knowledge of operating storage tank equipment, using protective equipment, self rescue and mutual rescue in emergency situations.

In short, cleaning chemical storage tanks requires strict adherence to safe operating procedures and the use of appropriate protective equipment and instruments. It is crucial to ensure the safety of personnel and the stability of the environment in response to possible emergencies. Emphasize prevention and safety education and training, equip operators with relevant skills and knowledge, and reduce accident risks.
