Mobile Toilet Connected to Fire Hydrant
When connecting a mobile toilet to a fire hydrant, it is necessary to maintain a distance of more than 1.5 meters from the hydrant and meet the requirements of fire protection design specifications.

1. Distance Requirements: Ensuring Unobstructed Access to Fire Protection Facilities
According to relevant safety guidelines, the distance between a mobile toilet and a fire hydrant must be strictly controlled to more than 1.5 meters. The core purpose of this regulation is to ensure that in emergency situations such as fires, firefighters can quickly and unobstructedly operate the hydrant, connect hoses, and initiate firefighting operations. If the distance is too close, the mobile toilet may block the hydrant's interface or obstruct the path for hose laying, delaying rescue efforts. For example, in temporary event venues or construction areas, if a mobile toilet is placed adjacent to a hydrant, the operational space may be further compressed due to crowded personnel or equipment stacking, increasing safety hazards. Therefore, the minimum distance of 1.5 meters is a safety threshold verified through practice and must be strictly enforced.
2. Fire Protection Design: Reducing the Risk of the Mobile Toilet Itself
As a temporary facility, the fire protection performance of a mobile toilet directly affects overall safety. Specifications require its design to meet the following conditions:
- Material Flame Retardancy: The main structure and interior decoration materials of the toilet must use B1-grade or higher flame-retardant materials. These materials are less likely to burn under open flames or high temperatures and self-extinguish when removed from the fire, effectively slowing the spread of flames. For example, exterior wall panels can be made of fiberglass-reinforced plastic or metal sandwich panels, and interior partitions can use fire-resistant gypsum boards, avoiding the use of flammable materials such as polystyrene.
- Electrical Safety: Electrical equipment such as lighting and ventilation in the toilet must be equipped with leakage protection devices, and the insulation performance of the wiring must be regularly inspected. Leakage protectors can automatically cut off the power supply in the event of a leakage, preventing fires or electric shock accidents caused by electrical faults. At the same time, electrical wiring must be protected by metal conduits to prevent short circuits due to mechanical damage.
- Ventilation Optimization: The ventilation opening area must be no less than 5% of the total toilet area to ensure internal air circulation and reduce the concentration of flammable gases. Ventilation openings should be located at the top or high on the side walls to avoid direct contact with flammable materials on the ground and should be fitted with metal protective grilles to prevent foreign objects from entering. Good ventilation also reduces odor accumulation and improves user comfort.
Through dual safeguards of distance control and fire protection design, mobile toilets can meet temporary usage needs while minimizing fire risks and ensuring public safety.
