Yunnan Jianfeng Conducted Emergency Drill for Ammonia Leakage Accident
News In order to further improve the on-site handling capacity of ammonia leakage accident and timely control and eliminate the harm of ammonia leakage accident, Yunnan Jianfeng Cement Company carried out emergency rescue drill for ammonia leakage accident on August 9, 23, July 6. This exercise simulated the scene of leakage of ammonia tank valve and ammonia overflow at the end of the kiln: during the routine inspection of ammonia tank area, the on-duty post did not wear protective equipment to enter the tank area as required. due to sudden leakage of ammonia in the tank area, the on-duty post inspection withdrew from the tank area in time, but excessive ammonia inhalation caused nausea, irritation and dyspnea, sending a distress signal to the central control. At the same time, the central control operator found that the denitration system at the end of the kiln was stopped, and the alarm showed that the ammonia concentration in the ammonia tank area exceeded the standard. Upon receiving the post inspection distress signal, the central control operator immediately reported to the workshop management personnel and the safety and environmental protection department, and notified the adjacent post workers on site to confirm the cause of the failure.
"accident", Yunnan peak the first time to start the emergency rescue plan. The ammonia leakage emergency response team led by clinker supervisor Xiong Guoyun wore complete protective equipment and entered the leakage area to check the leakage. It was found that a valve was not closed tightly, causing ammonia leakage. After closing the valve to confirm that there is no continuous leakage, open the water pipe nozzle in the ammonia tank area to spray water, and the sprinkler will flush the leaking part to dilute the ammonia concentration and reduce the danger degree during personnel handling. At the same time, arrange the employees wearing safety protective clothing to open the discharge valve and discharge the ammonia in the tank into the accident pool. Finally, the emergency team tested the surrounding water quality and air to confirm the standard, and the exercise was successfully completed. After the
exercise, exercise commander Zhou Jiping commented on the problems exposed during the exercise and summarized and guided them. (Liu Fengbin /
Shi Wenting /) How to save yourself when
ammonia leaks?
Ammonia is an aqueous solution of ammonia. After inhalation, it is irritating to the nose, throat and lungs. It can cause cough, shortness of breath and asthma. It can suffocate due to throat edema and death. Pulmonary edema can cause death. Ammonia splashes into the eyes can cause serious damage and even blindness, skin contact can cause burns.
In case of ammonia gas or ammonia water leakage, if the personnel have skin contact, they should immediately wash with water for at least 15
15 minutes, or rinse with 3% boric acid solution, and then seek medical attention immediately. Those who inhale ammonia should quickly escape from the scene to a place with fresh air to keep the respiratory tract unobstructed. If someone ingested or inhaled the substance, other people do not use mouth-to-mouth artificial respiration. Use a one-way valve small respirator or other appropriate medical respirator for artificial respiration.
People who take ammonia by mistake should rinse their mouth immediately, take diluted vinegar or lemon juice orally, and then seek medical attention immediately. (Liu Fengbin)
