Mobile Toilet Acceptance Instructions

The acceptance of mobile toilets should be systematically carried out from five aspects: key nodes, structural materials, functional safety, process records, and special scenarios to ensure that the facilities meet usage standards and safety requirements.

I. Key Acceptance Usage Nodes
The acceptance should cover six types of actions throughout the entire lifecycle of mobile toilets: entry, usage, cleaning, replenishment, maintenance, and relocation. Focus on verifying aspects such as water supply and drainage (flushing pressure, sewage discharge smoothness), ventilation (air exchange efficiency, odor control), lighting (illumination compliance, emergency functionality), door locks (tight closure), and cleaning and maintenance (tool provision, operational convenience) to ensure normal functionality and the absence of design defects in each aspect.

II. Structural and Material Acceptance

1. Welding Process: Check the uniformity of welds and the height of the weld toes. The penetration of qualified welds should reach at least 70% of the base material thickness, with surface depressions or protrusions not exceeding 0.5mm, which can be verified through ultrasonic testing or magnetic particle inspection.
2. Material Compliance: Require suppliers to provide material quality certificates, verify the grade of light-duty square steel (e.g., Q235B) and the edge thickness of angle steel (≥3mm), and inspect the thickness of the hot-dip galvanized layer (average ≥85μm, local ≥70μm) to avoid simple rust prevention treatment in the inner cavity.
3. Corrosion Resistance: In humid environments (e.g., scenic spots), verify the integrity of the galvanized layer in the frame's inner cavity to prevent rusting within three years; prioritize the use of galvanized steel plates or stainless steel materials to enhance corrosion resistance.

III. Functional and Safety Acceptance

1. Facility Functionality: Test the stability of the water pressure in the flushing system, water-saving efficiency, and the smoothness of the sewage discharge pipes; check whether lighting, ventilation, and barrier-free facilities (e.g., handrails, ramps) comply with national standards; for new types of toilets, verify the operation of solar power systems and smart sensing devices.
2. Structural Safety: Evaluate the stability of the box frame, wind and earthquake resistance (wind resistance not less than Level 10, earthquake resistance not less than Level 8), and the slip resistance of the floor; check the reliability of door and window locks to ensure user privacy and property safety.
3. Hygiene Indicators: Monitor air quality (ammonia and hydrogen sulfide concentrations), the total number of surface bacteria, and microbial indicators such as coliform bacteria; assess the cleanliness of high-frequency contact areas such as toilets and washbasins, using tools such as fluorescent detection agents to quantify the effects.

IV. Acceptance Process and Records

1. Room-by-Room Records: Detailed records should be kept of the number, dimensions, doors and windows, sanitary ware, floors, signs, and accompanying items, with photos, readings, and drawings associated using the same number.
2. Risk Boundaries: Do not use fragrances or surface cleaning to mask ventilation and drainage issues; electrical and lifting matters should be handled by professionals; formal evidence should be retained for matters involving safety, ownership, or key performance.
3. Re-inspection Standards: After rectification, re-inspect according to the original actions, and hand over keys, spare parts, instructions, and daily inspection forms; for items that fail, specify the scope of impact, temporary measures, responsible persons, and re-inspection dates.
4. Traceability: During review, check whether the acceptance records are completed according to the six types of actions, ensure that all conclusions are written into the same record, and use a fixed perspective for on-site photos and label them with object numbers.

V. Special Scenario Acceptance

1. Scenic Spot Environment: Focus on verifying the wind and earthquake resistance of the welded frame (e.g., structural safety during typhoon season) and the rust prevention and corrosion resistance of the materials (e.g., the integrity of the galvanized layer in the inner cavity of light-duty square steel).
2. Temporary Relocation Sites: Verify the structural stability of mobile toilets and the smoothness of sewage discharge pipes in extreme environments such as floods.
