How to deal with ammonia leakage

(/), the harm of ammonia gas is well known. Inhaling ammonia will do great harm to human body and endanger life, and ammonia leakage will also do harm to the environment. So what should I do if ammonia leaks?

Ammonia, also known as liquid ammonia, is a toxic and combustible gas. Ammonia is easily soluble in water, 1 part of water can dissolve 700 parts of liquid ammonia, and the aqueous solution of ammonia is called ammonia water. In order to facilitate transportation and storage, gaseous ammonia is usually pressurized or cooled to obtain liquid ammonia. In the process of production, storage, transportation and use, if leakage occurs, it will easily lead to combustion, explosion or poisoning accidents, and careless disposal will have serious consequences.

(1) A small amount of leakage. Evacuate all personnel in the area. Prevent inhalation of steam and contact with liquid or gas. Disposal personnel should use breathing apparatus. It is forbidden to enter the closed space where ammonia gas may accumulate, and the ventilation should be strengthened. Only when safety is ensured can plugging be carried out. The leaked container should be moved to a safe place, and the valve can only be opened to relieve pressure when safety is ensured. Leakage can be collected and absorbed by inert absorbent materials such as sand and vermiculite. The collected leakage should be placed in a sealed container and labeled accordingly for disposal.

(2) a large number of leaks. Evacuate all unprotected personnel there and move to the upwind direction. Leakage disposal personnel should wear fully enclosed heavy chemical protective clothing and air respirator, and dilute the leakage area with spray water after taking personal protective measures. Through the dilution of the water gun, the ammonia gas in the field gradually dispersed, and the leakage point was blocked with a spark-free tool. Give an alarm to the local government and "1 19" as well as the local environmental protection department and the public security traffic police department, and the alarm content shall include the accident unit; The time and place of the accident, the name of the chemicals, the amount of leakage and the degree of danger; Whether there are any casualties and the name and telephone number of the alarm person. It is forbidden to touch or cross the leaked liquid ammonia, prevent leakage from entering sewers and drainage channels, and strengthen ventilation. Smoking and open flames are prohibited in the premises. Under the condition of ensuring safety, the leaking container should be blocked or turned over to avoid the leakage of liquid ammonia. Spray water to suppress steam or change the flow direction of steam cloud, but it is forbidden to directly impact the leaked liquid ammonia or leakage source with water. Prevent leakage from entering water bodies, sewers, basements or confined spaces. It is forbidden to enter a confined space where ammonia gas may accumulate. After cleaning, all protective clothing and equipment should be cleaned before storage and reuse.
