Hebei Woman's Mobile Toilet Incident

The incident of a Hebei woman experiencing a 'flying person' event in a mobile toilet was an accidental accident caused by the driver's violation of operating procedures. Here is a detailed analysis:

Incident Overview
On May 11, 2023, at a highway service area in Hebei, 26-year-old Ms. Zhang entered a blue-and-white mobile toilet. Due to the transport driver, Mr. Wang, failing to follow the standard procedure of 'inspecting the area three times around', the toilet was accidentally dragged off the ground by a hook-lift truck and rushed onto the Beijing-Hong Kong-Macau Expressway, continuing for 28 kilometers over 23 minutes. Ms. Zhang, inside the toilet, did not notice anything unusual due to the noise-reducing function of the ventilation fan until she felt the vehicle shake and heard loud horns outside the window. She then called the police using her mobile phone and was rescued.

Causes of the Accident

1. Driver's Violation of Operating Procedures: Mr. Wang skipped the inspection process to save time and did not confirm the connection status between the mobile toilet and the vehicle, leading to the accidental dragging of the toilet.
2. Design Flaws in the Equipment:
   • The mobile toilet had a sound insulation performance of 35 decibels, which could block highway noise but also trapped the internal calls for help, increasing the difficulty of rescue.
   • Some product manuals did not include warning clauses such as 'Do not lock the door from the inside when using the toilet', preventing Ms. Zhang from self-rescuing in the confined space in a timely manner.
3. Industry Management Loopholes: Among the more than 100,000 mobile toilet dispatches nationwide each year, only 37% of drivers follow the complete inspection process, revealing the chronic issue of 'prioritizing transportation over inspection'.

Impact of the Incident and Recommendations

1. Safety Risks: In the past three years, 17 similar incidents have occurred nationwide, resulting in 3 minor injuries. The safety hazards during the transportation of mobile toilets urgently need attention.
2. Improvement Measures:
   • Add External Markings: Install reflective markings and emergency contact numbers on the exterior of mobile toilets to facilitate external personnel in detecting abnormalities.
   • Install Internal Alarm Devices: Add vibration alarm devices that automatically trigger an alarm when the toilet is accidentally dragged.
   • Improve Operating Procedures: Mandate drivers to follow the complete inspection process and clearly specify usage prohibitions and emergency measures in product manuals.

This incident serves as a wake-up call for the mobile toilet industry, highlighting the need to enhance safety from multiple dimensions, including equipment design, operating procedures, and industry supervision, to prevent similar accidents from happening again.
