Weekly Topic on Ammonia Synthesis – Discussions on Safety in Ammonia Synthesis Plants 24/10/2011

Weekly topics on synthetic ammonia – Discussions related to safety in synthetic ammonia plants. \"Chemical industry, coal mining, construction, and non-coal mines\" are listed as the four high-risk industries. As a historically established sub-sector within the chemical industry, synthetic ammonia production is considered a high-risk industry, characterized by high temperatures, high pressures, as well as flammability and explosivity. Throughout the years, ammonia synthesis plants of all sizes have regarded safe production as the most important aspect of their operations; regular safety training and the reinforcement of safety awareness are essential. The hazards in ammonia synthesis plants are primarily present at the production site. Please discuss: what safety measures are in place when entering the production area, and what safety experiences or precautions should be observed during operations there. Higher scores will be given as appropriate based on participation, so everyone is encouraged to get actively involved.

Here, we have a six-piece set for entering the production area: safety shoes, work clothes, safety helmets, goggles, earplugs, and escape devices. The implementation has been successful; the escape device was used at first, but now it’s almost unnecessary to carry it! As a chemical industry professional, I personally believe that it is essential to keep safety principles in mind at all times, and to remain fully focused when on the production site. Upon hearing unusual noises or smelling foul gases, one must make their own judgments and carry out various operations only when safety is ensured. Extra caution and attention are required, especially during startup and shutdown processes. When performing operations, it is necessary to have an assessment of the safety risks involved; for example, high-pressure valves should only be operated from the side, and the valve stem must not be directed at the body ； When opening a furnace viewing port, safety goggles must be worn ； The use of mobile phones and similar devices is strictly prohibited at the production site. Be careful of yourself – it’s your own life you’re protecting. The above are personal insights for reference only; everyone is welcome to discuss and learn together*
Here is a story about an oxygen cylinder explosion: What happened: After completing a cutting task on site, while cleaning up the work area and removing the pressure regulator from the oxygen cylinder, an explosion occurred suddenly. Fortunately, it did not explode in the direction where people were standing. Reasons: 1. An oily substance was found at the bottom of the oxygen cylinder; when this oily substance comes into contact with high-purity oxygen, a chemical reaction occurs that releases heat. The outdoor temperature at the time of operation was particularly high, reaching 38–39 degrees. 2. Upon careful inspection of the cylinder, it was found that it had been labeled as a nitrogen cylinder at the time of manufacture, but the contractor altered its color from black to blue without authorization, violating the regulations regarding the use of gas cylinders. 3. An inspection of the oxygen production facility revealed that its license for handling hazardous chemicals only allowed the handling of nitrogen, carbon dioxide, argon, and acetylene, and it did not possess the qualifications necessary for the production and sale of oxygen. Summary: Fortunately, no casualties were caused by this explosion. From the cause of it, we can see that our safety supervision is extremely inadequate; outdated management methods have led to poor compliance on the part of employees. Taking shortcuts when it comes to safety will surely cost us dearly; I urge everyone to pay attention to managing contractors properly.
1. Warning signs should be placed at the entrance to the toxic production area to inform people about the presence of harmful substances in that production workshop. 2. The flow direction of the important pipeline fluids is indicated, and the equipment is labeled. 3. Staff should receive enhanced training to understand the importance of safe work.
Be prepared for danger in times of peace; always maintain a mindset as if facing a great threat
Safety measures for entering the production site: Be sure to wear proper safety gear. This is not meant to meet inspection requirements; it’s about always keeping one’s own safety in mind ； It is essential to understand the production process, especially in high-temperature and high-pressure environments; one must not take risks when working, and the eight types of permits must be obtained as required.
I. At the individual level: Since one has chosen to work in a job that involves serious hazards, it is necessary to understand the properties of the chemicals related to that job before starting work (such as whether they are toxic, explosive, flammable, corrosive, etc.). One should be aware of the color and odor of these chemicals; one should not be clueless when encountering a certain color or smelling a particular odor； II. Regarding the factory: Eye-catching informational brochures detailing the physical or chemical properties of highly hazardous chemicals, as well as the procedures for dealing with leaks and escape methods, should be displayed in easily visible locations within the factory to serve as a constant reminder to everyone.
Pay close attention to any leaks, and carry out the necessary procedures for working with fire during on-site construction; ensure thorough gas displacement to prevent the accumulation of gases. In ammonia synthesis, explosions and poisoning are major concerns, and compression equipment is also one of the hazard points. Always be mindful of safety and think before you act

Safety is a systems engineering issue. There must be specialized agencies or organizations, staff, and sufficient safety equipment. Everyone must understand safety knowledge, master safety skills, and participate in various safety drills
There are plenty of systems, but how is the actual, concrete work carried out? This issue is the most important; only by improving the quality of frontline personnel can it be effectively controlled.
