Disinfection of Isolation Mobile Toilets

The disinfection work for isolation mobile toilets must adhere to strict standards, ensuring hygiene and safety through frequent and multi-step disinfection measures. The key points are as follows:

I. Disinfection Frequency and Scene Coverage

During the pandemic, the disinfection frequency of isolation mobile toilets should be dynamically adjusted based on usage scenarios. For example, Shanghai Pudong Sanxing Environmental Sanitation Co., Ltd. adopts a 'point-to-point' comprehensive disinfection model when ensuring the hygiene of isolation shelters and transfer points, focusing on toilet and office building areas to ensure no dead zones are left uncovered. The sanitation突击队 (sanitation task force) at Jianghan Shelter implements a 'one-customer, one-disinfection' system, where cleaning and disinfectant spraying are carried out immediately after each use to meet high-density usage demands. Such frequent disinfections can effectively block the risk of virus transmission through fecal-oral routes or aerosols.

II. Disinfection Techniques and Standards

The maintenance of mobile toilet facilities must comply with microbial load control standards, with cleaning procedures including surface disinfection, air purification, and other steps. For instance, the use of food-grade hydrogen peroxide雾化消毒 (atomized disinfection) technology offers the following advantages:

• Rapid inactivation of pathogens: Pathogens can be inactivated at a rate of 99.6% within 120 seconds, suitable for rapid turnover in high-frequency usage scenarios;
• High safety: The food-grade formula leaves no residue in the environment and has low irritancy to humans, making it suitable for long-term use in isolation areas;
• Comprehensive coverage: The atomized form can penetrate hidden areas such as toilet crevices and ventilation systems, compensating for the shortcomings of traditional wiping.

III. Personnel Training and Management

The effectiveness of disinfection relies on the standardization of operations, so it is necessary to strengthen the training of relevant personnel:

• Popularization of epidemic prevention knowledge: Including virus transmission routes, disinfectant ratios, and the wearing of personal protective equipment (PPE), to ensure that operators master scientific methods;
• Strengthening of behavioral norms: For example, confirming that the toilet is unoccupied before disinfection and allowing it to stand for a certain period after disinfection before reopening to avoid direct contact between disinfectants and humans;
• Supervision mechanism: Ensuring process compliance through regular inspections and recording disinfection times and scopes.

IV. Targeted Measures for Special Scenarios

In high-risk areas such as shelter hospitals, the disinfection of mobile toilets should be combined with environmental characteristics:

• Increased disinfection of ventilation systems: Regularly disinfect exhaust ducts and ventilation fans to prevent aerosol accumulation;
• Waste disposal: Toilet paper, disinfectant wipes, and other waste should be sealed and collected separately for disposal to avoid cross-contamination;
• Emergency response plan: If a confirmed case is found to have used the toilet, it should be immediately sealed and subjected to deep disinfection, including high-frequency contact areas such as floors, walls, and door handles.

Through the above measures, isolation mobile toilets can establish a closed-loop management system of 'use-disinfection-reuse', minimizing the risk of infection.
