Mobile Toilet Disinfection Specification

The mobile toilet disinfection specification must be strictly implemented in terms of frequency, disinfectants, areas, operations, and management, with specific requirements as follows:

1. Disinfection Frequency
Adjust the disinfection frequency dynamically based on the usage scenario and foot traffic:

• High-frequency scenarios (e.g., large exhibitions, peak tourist seasons in scenic spots): Conduct comprehensive disinfection at least once a day; if foot traffic is extremely high (more than dozens of people per hour), disinfect local areas such as toilet seats and door handles every 4-6 hours.
• Medium-frequency scenarios (e.g., small construction sites, daily park use): Perform comprehensive disinfection once every 1-2 days, with additional local cleaning based on odors or stains during this period.
• Low-frequency scenarios (e.g., remote construction sites): Conduct comprehensive disinfection once a week, and clean and seal the facilities when idle to reduce bacterial growth.
• Special environments (e.g., areas around hospitals, quarantine sites during epidemics): Follow epidemic prevention standards for comprehensive disinfection 2-3 times a day, using high-efficiency products such as chlorine-based disinfectants.
• During infectious disease outbreaks: Disinfect contact surfaces every 2 hours as required by disease control authorities, using 75% alcohol or chlorine-based disinfectants.

2. Disinfectant Selection
Choose disinfectants that are broad-spectrum bactericidal and non-corrosive to plastics, such as quaternary ammonium compounds or hydrogen peroxide-based disinfectants. The dilution ratio must be precise to the ppm level to avoid compromising effectiveness or damaging facilities due to improper concentration.

3. Key Disinfection Areas
High-frequency contact surfaces are the core of disinfection, including toilet seats, the inner sides of toilet bowls, door handles, flush buttons, and faucets. These areas are prone to retaining pathogens and require focused wiping or spraying with disinfectant.

4. Disinfection Operation Requirements

• Contact Time: The disinfectant must remain on the surface for ≥10 minutes to ensure the killing of microorganisms.
• Operation Steps:
  1. Discharge waste and close the water collection device.
  2. Rinse the interior and wipe surfaces with a cleaning agent.
  3. Disinfect key areas separately.
  4. Replenish toilet paper, hand soap, and other supplies.
  5. Check for leaks, cracks, and odors, and confirm no issues before reopening.

5. Management Standards and Quality Control

• Standardized Procedures: Regular service providers must prepare a Cleaning Inspection Card to clarify operational standards.
• Personnel Assessment: Frontline cleaners must pass practical assessments. Supervisors should inspect ≥20% of facilities daily, using a turbidity meter to test water clarity and an ATP fluorescence detector to verify surface cleanliness.
• Data Traceability: Record operation times, disinfectant usage, and abnormalities to form an electronic log for traceability.

By following these specifications, the health risks associated with mobile toilets can be effectively controlled, ensuring the well-being of users.
