Treatment and disposal methods of liquid ammonia leakage

Common disposal methods of liquid ammonia leakage;

1. Emergency response: In case of liquid ammonia leakage accident, take emergency measures immediately to ensure the safety of personnel. This includes evacuating people, wearing appropriate protective equipment and notifying relevant departments and local emergency personnel.

2. Isolate the leakage source: determine the leakage source as soon as possible and take measures to isolate it. Close relevant equipment or valves and cut off the supply of liquid ammonia to reduce the scale of leakage.

3. Ventilation treatment: ensure that the leakage area is well ventilated, so as to quickly dilute and diffuse liquid ammonia gas. Turn on all available ventilation equipment and ensure indoor and outdoor air circulation.

4. Physical protection: Use appropriate protective equipment, such as breathing apparatus, protective clothing and gloves, to reduce the risk of personnel contacting liquid ammonia. These devices should meet the relevant safety standards and be properly worn and used by trained personnel.

5. Leakage removal: After the leakage of liquid ammonia is controlled, it must be removed. This includes using absorbent or chemical neutralizer to absorb or neutralize liquid ammonia, and taking appropriate measures to treat waste liquid.

6. Leakage investigation and report: investigate the leakage of liquid ammonia, determine the leakage reason and take preventive measures. According to the requirements of local laws and regulations, submit necessary reports to relevant departments and local governments.

Liquid ammonia leakage accident is a serious safety accident, so it is necessary to take emergency response and safety protection measures in time to minimize losses and protect personnel safety. When liquid ammonia leaks, the emergency plan should be started immediately, and the personnel should be evacuated to a safe area quickly, and the relevant departments and professionals should be informed to deal with it. At the same time, protective equipment, such as breathing apparatus and protective clothing, must be worn to prevent liquid ammonia from causing harm to human body. In the process of treatment, appropriate measures should be taken, such as blocking the leakage source and adsorbing liquid ammonia with chemical adsorbent, to control the leakage and prevent further diffusion. In addition, relevant units and local governments should be notified in time to coordinate resources, jointly handle accidents, and conduct accident investigation and risk assessment to avoid similar accidents from happening again. Through scientific and effective emergency response and safety protection measures, the safety of personnel can be protected to the maximum extent and the impact of accidents on the environment can be reduced.

Legal basis:

People's Republic of China (PRC) Law on the Prevention and Control of Environmental Pollution by Solid Waste (revised in 2020);

Chapter VIII Legal Liability Article 115 Whoever, in violation of the provisions of this Law, imports solid waste from inside and outside People's Republic of China (PRC) shall be ordered by the customs to return the goods and be fined not less than 500,000 yuan but not more than 5 million yuan. The carrier shall be jointly and severally liable with the importer for the return and disposal of solid waste as stipulated in the preceding paragraph.
