Regulations for Mobile Toilets at Construction Sites
The regulations for mobile toilets at construction sites cover multiple aspects such as site selection, installation, use, maintenance, safety, and environmental protection, as detailed below:
Site Selection and Installation: The location should be away from hazardous construction areas, such as the operating radius of tower cranes and the edges of foundation pits. It should also avoid water sources, drinking water points, drainage outlets, and easily polluted areas. For high-rise construction sites exceeding 8 floors, temporary toilets should be installed every 4 floors. The foundation should avoid low-lying areas prone to water accumulation and ensure it is solid and non-subsiding. During installation, the toilet should be placed horizontally, and the fixing bolts should be tightened to prevent wind-induced tipping.
Quantity and Capacity Adaptation: Choose the number of toilets based on the number of workers on site. For single-person use, each toilet can accommodate 1-2 people at a time. For multiple-person use, it is recommended to select double-unit models. During peak construction periods, a 20% reserve can be added.
Material and Structure: Prioritize stainless steel or thickened plastic shells that are waterproof and sun-resistant, with a service life of 3-5 years. The interior should be equipped with anti-slip floors and independent flushing systems. In winter, models with insulation functions can be selected.
Functional Configuration: Consider barrier-free facilities, dedicated compartments for women, or ventilation and deodorization devices. The toilet unit and supporting structure should have sufficient load-bearing capacity and stability, with rainproof, dustproof, and leak-proof designs. Key parts should have waterproof and anti-corrosion treatments.
Daily Use and Maintenance: Before use, check if the flushing system is functioning properly and if there are any leaks in the fecal collection tank. Flush at least once a day and regularly clean up waste. The leasing party should clean at least once a day and disinfect twice a week. In case of rain or snow, promptly clean up accumulated water inside and outside the toilet.
Safety and Emergency Measures: Install anti-slip mats, with handrail heights ranging from 0.8 to 1.1 meters. Equip with fire extinguishers and emergency lighting, and ensure sufficient lighting during night construction. Set up independent fire separation distances for equipment rooms and adopt waterproof and anti-electric shock designs for electrical equipment. In case of equipment failure, immediately post a 'Out of Service' sign and contact for repairs. Develop rapid response, personnel evacuation, on-site handling, and post-event treatment procedures for accidents, natural disasters, and sudden pollution incidents.
Environmental Protection and Compliance Requirements: It is prohibited to dispose of construction waste or chemicals in the toilets. Fecal treatment should comply with local sanitation regulations, and regular cleaning and transportation units should be selected. Waste liquid and solid waste should be collected separately, regularly cleaned and transported, and records should be kept. The toilets should comply with the 'Urban Public Toilet Design Standard' (CJJ14-2016), and the leasing party should have an 'Environmental Sanitation License'.
