Removal of Mobile Toilets in Fangcang Hospital

The removal of mobile toilets in Fangcang hospitals should be carried out in accordance with the overall disposal plan for the Fangcang facilities. Typically, this involves first closing the water supply and drainage valves, emptying the sewage, and then dismantling the components for classified disposal. The specific process is as follows:

1. Preparation before Removal
According to the regulations of the national and Shanghai Centers for Disease Control and Prevention, the Fangcang hospital must undergo comprehensive disinfection and meet safety standards before removal operations can commence. As a supporting facility of the Fangcang hospital, the removal of mobile toilets should be integrated into the overall material classification system to ensure coordination with the disposal plan for the main structure. For example, Shanghai Environmental Group has formulated a 'one-Fangcang-one-plan' strategy for different types of Fangcang hospitals (such as those converted from schools and exhibition halls), and the removal of mobile toilets must strictly adhere to the technical standards of the corresponding plan.

2. Component Dismantling and Protection
Removal should be carried out in sequence:

• Closing Valves and Emptying Sewage: First, close the water supply and drainage valves, and empty the sewage from the storage tank to prevent residual liquid from polluting the environment or affecting subsequent treatment.
• Dismantling Main Components: Dismantle the main frame, toilet compartments, storage tanks, etc., in sequence, paying attention to protecting the integrity of the components during the process. For example, toilet compartments and storage tanks in good structural condition can be retained for recycling to avoid damage caused by rough dismantling.

3. Classified Disposal of Materials
According to the 'Technical Standards for the Collection, Transportation, and Disposal of Materials from Fangcang Hospital Removal', the dismantled components should be classified based on their properties and resource value:

• Materials for Direct Reuse: Such as undamaged toilet compartments and storage tanks, which can be recycled to two-network integration sites after disinfection and assessment.
• Removal Waste: If components cannot be reused (such as aged or damaged frames), they should be treated as construction waste. The total amount of removal waste from Fangcang hospitals in Shanghai is estimated to be between 1210 and 1510 tons, and waste from mobile toilets should be included in this category.
• Epidemic-Related Waste: If the toilet has a history of contact with medical waste (such as storing infectious waste), it should be collected and transported according to special procedures. The total amount of epidemic-related waste is estimated to be between 15 and 30 tons.

4. Safety and Transportation Requirements
The removal process should be carried out by professionals who should pay attention to the weight and structural stability of the components to avoid collapse or personal injury caused by center-of-gravity shift or improper operation. The dismantled components should be arranged and organized in sequence, loaded onto transportation vehicles, and transported to designated locations for storage or further treatment to ensure no leakage or secondary pollution during transportation.
