Standards for Mobile Toilets

The standards for mobile toilets cover multiple aspects such as structural form, mobility method, sewage treatment method, height, and accessibility requirements, as detailed below:

In terms of structural form, mobile toilets are mainly divided into single-structure mobile toilets and composite-structure mobile toilets. Single-structure mobile toilets typically have a relatively simple structure and strong integrity, suitable for places with low space requirements and relatively simple usage scenarios. Composite-structure mobile toilets, on the other hand, are composed of multiple materials or structures, potentially offering advantages in functionality and stability to meet more complex usage needs.

Regarding mobility methods, there are lifting and handling-type mobile toilets, which mainly rely on external lifting equipment or manual handling to move positions, suitable for scenarios with low mobility frequency and short moving distances. Power-driven and towed-type mobile toilets have their own power systems or can be moved by vehicle towing, offering greater flexibility and convenience for situations requiring frequent movement or long-distance relocation.

Sewage treatment method is one of the important standards for mobile toilets. Common types include flush and non-flush suction-type mobile toilets. Flush-type toilets can better maintain internal cleanliness but require a water connection. Non-flush suction-type toilets handle waste through suction without the need for a water source, making them suitable for water-scarce areas. There are also circulating flush-type mobile toilets, which conserve water resources by recycling water while ensuring a certain level of flushing effectiveness.

In terms of height, mobile toilets are usually designed to be within 4 meters, primarily considering transportation safety and road clearance requirements. Excessively tall mobile toilets may encounter height restrictions from bridges, tunnels, etc., during transportation, increasing the difficulty and risk of transportation.

Accessibility requirements are also an indispensable part of mobile toilet standards. Their location should be close to public restrooms, with an area of no less than 4.00 square meters. Inside, there should be a wheelchair turning space with a diameter of no less than 1.5 meters to facilitate wheelchair users' entry, exit, and turning. The interior should be equipped with accessible toilets, accessible sinks, multifunctional tables, low-positioned coat hooks, and emergency call devices to meet the various needs of disabled individuals. Additionally, horizontal sliding doors or outward-opening hinged doors should be installed to ensure they can be smoothly opened in emergencies, safeguarding users' safety.
