The Ministry of Emergency Management interprets the "Notice on Further Strengthening the Safety Management of Ammonium Nitrate"

According to the website of the Ministry of Emergency Management, recently, the Ministry of Emergency Management, the Ministry of Industry and Information Technology, the Ministry of Public Security, the Ministry of Transport and the General Administration of Customs jointly issued the "Notice on Further Strengthening the Safety Management of Ammonium Nitrate" (hereinafter referred to as the "Notice")

1.

Answer: Ammonium nitrate has the dangerous characteristics of explosion when exposed to fire, high temperature, and violent impact

China is a large country in the production and use of ammonium nitrate.

In order to thoroughly implement the spirit of the important instructions on preventing and resolving major safety risks, earnestly implement the decision and deployment of the Party Central Committee and the State Council on safe production, and strengthen the safety risk management and control of the production, storage, sales, purchase, transportation, and use of ammonium nitrate, the Emergency Management Department is in Based on extensive solicitation of opinions, research and discussion, the "Notice" was jointly issued with the Ministry of Industry and Information Technology, the Ministry of Public Security, the Ministry of Transport and the General Administration of Customs to resolutely prevent serious accidents caused by ammonium nitrate and effectively protect the lives and property of the people.

2.

Answer: It mainly includes seven aspects: First, strengthen the source control of ammonium nitrate safety risks

3.

　　Answer: The "Notice" puts forward specific requirements for the storage of solid ammonium nitrate and ammonium nitrate solutions for ammonium nitrate manufacturers, operating (with storage) companies, and chemical companies that use ammonium nitrate:

　　For the solid ammonium nitrate warehouse: First, it is designed as a Class A warehouse, with a single-layer independent construction, with a closed structure, with a fire resistance rating of not less than Class II, and setting Class A fire doors and windows
.
Second, the storage capacity of a single warehouse should be no more than 500 tons.
No flammable and explosive materials are allowed to be stored within 50m of the warehouse, and no production devices and storage facilities involving flammable and explosive materials shall be built
.
Third, safety facilities such as forced ventilation, far-infrared thermal imaging monitoring and alarm, spray cooling and video surveillance must be perfected in the warehouse.
Safety facilities such as flame video recognition and alarm must be installed outside the warehouse, and relevant monitoring alarms and video monitoring signals must be connected to hazardous chemicals.
Safety production risk monitoring and early warning system
.
Fourth, solid ammonium nitrate must not be stored together with other types of articles, and must be stored separately in a limited amount, and excessive storage is strictly prohibited
.
Solid ammonium nitrate is strictly prohibited from contacting with combustible powder, incompatible organic matter and metals, strong acids, strong alkalis, and storage in the open air is strictly prohibited
.
Fifth, the hot work in the solid ammonium nitrate warehouse must meet the requirements of the "Special Operation Safety Regulations for Chemical Production Units" (GB 30871).
The whole process should be recorded and kept for at least one month.
Hot work must not be carried out in the warehouse that has not been emptied
.

　　For ammonium nitrate solution storage tanks: one is the construction of ammonium nitrate solution storage tanks in accordance with Class A and Class B liquid storage tanks
.
The ammonium nitrate solution tank group should be arranged separately, and the safety distance around the tank area should meet the relevant standards
.
The maximum capacity of the tank group does not exceed 1000m3, and the maximum capacity of a single tank does not exceed 200m3
.
Second, storage tanks must be separately equipped with heat preservation and cooling facilities.
Parameters such as liquid level, temperature, and flow rate should be connected to the DCS system and have alarm and interlock functions.
The cleanliness of storage tanks, pumps and pipelines should be strictly controlled to avoid oil Substances enter
.
Third, the storage temperature of the ammonium nitrate solution should not exceed 145℃, the concentration should not exceed 93% (mass), and the pH value, concentration, organic content and other parameters should be checked regularly to ensure that they are within the normal range
.
Fourth, the ammonium nitrate solution delivery pipeline should have measures to prevent clogging by crystallization
.

　　The relevant requirements of the "Notice" for the production and storage of ammonium nitrate are applicable to ammonium nitrate production and operation companies and chemical companies that use ammonium nitrate for production, but not to civil explosives production companies
.

　　4.
What specific requirements does the "Notice" put forward for preventing safety risks in the transportation of ammonium nitrate?

　　Answer: The "Notice" mainly puts forward five specific requirements in the road transportation of ammonium nitrate: one is that companies that carry ammonium nitrate must have the corresponding road transport qualifications for dangerous goods; the other is that ammonium nitrate transport vehicles are prohibited from operating on the road, and ordinary goods are not allowed.
Transport vehicles transport ammonium nitrate; the third is to clean up the residual chemicals, metal powder, coal, wood chips, etc.
in the compartment before loading the solid ammonium nitrate; the fourth is to strengthen the dynamic monitoring of ammonium nitrate transport vehicles; the fifth is to strengthen the driving Education and training of personnel and escorts
.

　　The "Notice" puts forward three specific requirements in the port transportation of ammonium nitrate: First, port companies must implement the requirements of "direct loading and direct access", and the port area does not store ammonium nitrate; second, port companies strengthen cooperation with shippers and carriers.
Communicate with people to improve the efficiency of loading and unloading of ammonium nitrate, and reduce the staying time of ammonium nitrate in Hong Kong; third, port enterprises improve emergency preparedness for various accident scenarios involving ammonium nitrate
.

　　5.
What issues should be paid attention to in order to strengthen the safety management of ammonium nitrate in accordance with the requirements of the "Notice"?

　　Answer: Ammonium nitrate is inherently dangerous and has a high safety risk.
Once an accident occurs, it is easy to cause serious consequences
.
In conjunction with the implementation of the "Notice" requirements, for strengthening the safety management of ammonium nitrate, the following points need to be emphasized:

　　The first is to earnestly implement the main responsibility of the enterprise
.
Ammonium nitrate production companies, ammonium nitrate business (with storage) companies, chemical companies that use ammonium nitrate, ammonium nitrate carriers, port companies that carry According to the requirements of the Law and relevant regulations and standards, strictly implement the responsibility of the company’s safety production director, implement the requirements of the "Notice", and effectively control the safety risks of ammonium nitrate
.

　　The second is to earnestly implement departmental supervision responsibilities
.
The safety supervision of ammonium nitrate involves multiple departments such as emergency management, industry and information technology, public security, transportation, customs, etc.
All relevant departments should strengthen coordination and form a joint force to continuously strengthen the safety supervision of the entire chain and life cycle of ammonium nitrate to protect the people Safety of life and property
.

　　The third is to strengthen publicity and education
.
In view of the dangerous characteristics of ammonium nitrate, all relevant departments and units should strengthen publicity and education to increase the awareness of the practitioners and the people involved in the life cycle of ammonium nitrate on the dangers of ammonium nitrate, and take multiple measures to construct an effective nitric acid.
Ammonium safety risk control barrier
