Mobile Toilet Specifications

The specifications for mobile toilets cover multiple aspects such as site selection, layout, facilities, safety, environmental protection, and barrier-free design, with specific requirements as follows:

I. Basic Site Requirements Mobile toilets should be located in flat and solid areas, avoiding low-lying and waterlogged zones to prevent rainwater backflow or foundation settlement. They should be kept away from obvious pollution sources such as garbage disposal sites and sewage discharge outlets, and maintain a minimum distance of 5 meters from dining areas and residential areas to reduce odor and noise interference. The site should have clearly defined entrances and exits with widths sufficient to meet the needs of equipment transportation and daily maintenance, ensuring smooth passage for people and vehicles.

II. Spatial Layout Specifications The number and spacing of public toilets should be determined based on the number of users, with a minimum of 1.5 square meters of personal space per person to avoid crowding. The recommended ratio of male to female toilet stalls is 1:1.5 to accommodate the longer usage time of women. Barrier-free toilet stalls are mandatory, with dimensions of at least 1.2 meters by 1.5 meters to facilitate wheelchair access. For temporary events (such as exhibitions and concerts), one mobile public toilet unit should be provided for every 50 people to ensure supply-demand balance.

III. Facility Configuration Standards

1. Sanitary Facilities: Equipped with sinks, mirrors, hooks, toilet paper holders, and flushing systems (or waterless flushing devices) to meet basic usage needs.
2. Ventilation and Lighting: Install exhaust fans to maintain air circulation and emergency lighting equipment to ensure safe usage at night or during power outages.
3. Anti-slip Design: Use anti-slip floor tiles and install handrails and anti-slip mats in toilet stalls to reduce the risk of slipping, especially ensuring the safety of the elderly and children.

IV. Safety and Environmental Protection Requirements The site layout should comply with fire safety regulations and be kept away from storage areas for flammable and explosive materials. The sewage system should be connected to municipal sewer networks or designated collection points, and direct discharge into natural water bodies such as rivers and lakes is strictly prohibited to prevent pollution. Operators should regularly clean and disinfect equipment and empty septic tanks to avoid odor diffusion and bacterial growth.

V. Special Requirements for Barrier-Free Toilets

1. Location and Area: Barrier-free toilets should be located near public restrooms, with an area of not less than 4 square meters and a wheelchair turning space with a diameter of at least 1.5 meters inside.
2. Facility Configuration: Equipped with barrier-free toilets (with handrails), low-level sinks (height ≤ 0.8 meters), multifunctional tables (for placing items), low-level coat hooks, and emergency call devices.
3. Door Design: Use horizontally sliding doors or outward-opening flat doors to prevent wheelchair entrapment and ensure rapid rescue in emergencies.

VI. Waterless Toilet Standards Such toilets should comply with the GB/T18092-2000 "Waterless Sanitary Toilets" standard, using technologies such as biodegradation and physical encapsulation to treat excreta, achieving water conservation and environmental protection. This standard has been implemented since October 1, 2000, and is applicable to water-scarce areas or temporary scenarios.
