The control during the transportation of ammonia water is the core of safe transportation

The transportation of ammonia water is a crucial link connecting production, storage, and use. Due to its volatility and corrosivity, as well as the need to adhere to full-process control requirements such as sealing and corrosion prevention, temperature control and sun protection, smooth loading and unloading, route compliance, and emergency preparedness during transportation, it is essential to strictly comply with relevant laws, regulations, and industry standards to ensure safety, compliance, and no leakage throughout the entire transportation process, thereby safeguarding personnel, property, and environmental safety.
The selection of transportation vehicles must align with the characteristics of ammonia water. Priority should be given to dedicated tank trucks, tank ships, or corrosion-resistant enclosed containers. Transportation vehicles must possess hazardous goods transportation qualifications, and the tank body should be constructed from corrosion-resistant materials or lined with corrosion-resistant layers, such as fiberglass or polyethylene, to prevent corrosion and damage from ammonia water. The tank body should be equipped with safety facilities such as thermometers, level gauges, safety valves, and emergency shut-off devices to ensure real-time monitoring of the tank body's status during transportation and timely response to abnormal situations. The interior of the transportation vehicle's carriage should undergo anti-corrosion and anti-seepage treatment, and be equipped with explosion-proof lighting and ventilation equipment to prevent the accumulation of ammonia gas.
Loading operations must be conducted in well-ventilated areas, away from densely populated areas and sources of ignition. Operators must wear a full set of alkali-resistant protective gear, including acid and alkali-resistant gloves, chemical-resistant goggles, alkali-resistant work clothes, protective masks, etc., to avoid skin and eye contact with ammonia water or inhalation of ammonia gas. During loading, care must be taken to handle gently and avoid violent impacts and tipping to prevent container damage and leakage. The loading volume must be strictly controlled within 90% of the tank's capacity, with a certain amount of expansion space reserved to prevent the tank from exceeding its capacity due to the volume expansion of ammonia water when the temperature rises, which could lead to leakage. After loading, the tank's sealing status must be checked to ensure no leakage occurs. At the same time, warning signs such as "Corrosive Substance" and "No Open Flames" should be prominently displayed on the vehicle, and hazard signs for the transportation of dangerous goods should be equipped.
The control during transportation is the core of safe transportation. The transport vehicles need to maintain stable driving, avoiding severe bumps, sudden braking, and sharp turns to prevent the tank body from shaking and causing ammonia leakage. During transportation, it is necessary to keep away from heat sources, open flames, and direct sunlight. In summer, sunshade and cooling measures should be taken, such as using sunshades and spray cooling, to control the tank body temperature not exceeding 30°C. In winter, anti-freezing measures should be taken to prevent ammonia water from freezing and damaging the tank body. The transportation route needs to be planned in advance, giving priority to avoiding sensitive areas such as densely populated areas, schools, hospitals, and residential areas. Choose routes with stable road conditions, good ventilation, and away from heat sources. Try to avoid transportation at night. If night transportation is necessary, specially-assigned personnel should be provided for guarding and strengthening patrols.
Loading and unloading operations must be conducted in a standardized manner. Unloading should be performed in a well-ventilated area, with valves opened slowly to control the unloading speed and prevent ammonia water from splashing out. After unloading, any residual ammonia water in the tank must be cleaned up, the valves closed, and the tank's sealing condition checked to ensure no residual leakage. Transportation personnel must undergo professional training, familiarize themselves with the characteristics, transportation regulations, and emergency handling methods of ammonia water, and pass relevant assessments before taking up their posts. During transportation, they must monitor the tank's condition throughout the journey. If any leakage, abnormal odor, or other issues are detected, they must immediately stop the vehicle, set up a warning area, organize personnel to evacuate, and take corresponding emergency measures.

Emergency response preparations are indispensable. Transportation vehicles must be equipped with emergency washing devices, leakage handling tools (such as sand, absorbent cotton, etc.), and first-aid drugs. In the event of a small amount of leakage, immediately use sand or absorbent cotton to absorb the leakage, collect it, and conduct harmless treatment. If a large amount of leakage occurs, quickly construct a cofferdam to contain it and prevent the spread of ammonia water. At the same time, contact relevant departments for emergency response to avoid environmental pollution and personal injury. Through standardized transportation control throughout the entire process, the safety of ammonia water transportation can be effectively guaranteed, ensuring the smooth delivery of ammonia water to the point of use.
