Dangerous point (source) refers to the potential dangerous parts or positions in production equipment, posts or places, which are easy to cause personal injury accidents, building damage, equipment damage and other accidents, and also the key parts or positions that need to be controlled and managed to ensure safe production. According to the possibility of accidents at dangerous points (sources) and the severity of accident consequences, they are generally divided into four grades: A, B, C and D or I, II, III and IV.
(1) A-level (first-level) danger points (sources) refer to many accident-inducing factors that are difficult to control. Once an accident occurs, many people will be killed or injured.
(2) Grade B (2) Danger points (sources) refer to many accident-inducing factors that are difficult to control and prone to casualties or multiple injuries.
(3) A C-level (III) danger point (source) refers to a place where there are hidden factors of accidents, and the possibility of accidents is high, or accidents have occurred, although the risk of major accidents is low.
(4) D (4) Dangerous point (source) refers to the possibility of a general injury accident with a certain degree of danger.
What is traffic streamline? What do you mean, dangerous? What are these three categories? Which is the most dangerous?
Traffic streamline (driving route) refers to the trajectory of the car when it is regarded as a particle.
Danger point: the point where traffic flow lines cross each other. Divided into bifurcation points (bifurcation points), confluence points (confluence points) and conflict points (intersection points).
The conflict point is the most dangerous.
What is the danger point (source)
Refers to a specific place with potential safety hazards.
What is the so-called danger point when working in a substation?

Analysis and pre-control of dangerous points I. Meaning and characteristics of dangerous points
Danger refers to the possibility of injury, damage or failure. The so-called dangerous points refer to the places, parts, places, tools, behaviors and actions where danger may occur during the operation. Refers to the events that may endanger the health and life safety of employees, the safety of machinery and equipment, affect the normal operation and even cause economic losses in power production operations. Danger points include three aspects: first, the working environment that may cause harm. For example, toxic substances in the working environment will directly or indirectly endanger the health of workers and induce occupational diseases. Second, objects such as machinery and equipment that may cause harm. For example, mechanical equipment does not have a safety shield, and moving parts are outside, which will cause harm to the human body; If people touch the live power cord, they will get an electric shock. Third, the operator violates the safety work rules and operates at will. For example, some workers do not wear seat belts when working high above the ground, and even if they do, they do not fasten them as required. Unsafe factors in this working environment, unsafe state of machinery and equipment, and unsafe behavior of workers in operation may directly or indirectly lead to accidents. We can all regard them as dangerous points in operation and take measures to prevent or eliminate them.
Danger points are hidden dangers that induce accidents. If not treated and prevented, it may turn into an accident under certain conditions. Only by analyzing pre-control in advance and taking preventive measures can we save the day and ensure safety. The analysis and pre-control of dangerous points is just such an effective method to actively prevent accidents.
Analysis and pre-control of dangerous points is a method to predict and prevent dangerous points that may cause accidents in advance. It requires leaders and workers at all levels to analyze and find dangerous points that may endanger the safety of people or equipment in advance according to the work content, working methods, mechanical equipment, environment and personnel quality, and then study and formulate reliable safety precautions according to relevant safety laws and regulations to achieve the purpose of preventing accidents.
The theory of risk point analysis and pre-control is a summary of the long-term practical experience of power enterprises in fighting accidents, a product of the collective wisdom of the broad masses of workers, and an effective method to prevent accidents and ensure safe production in the new period.
What does the food safety risk point mean?
1. Food safety risks in catering service industry mainly include management system, personnel management, raw material procurement and processing.
2. Food safety refers to whether food will cause acute, chronic or potential harm to consumers' health. Causes or substances that cause health hazards to consumers are called hazards. According to the nature of hazards, hazards can be divided into biological hazards, chemical hazards and physical hazards.
3. Safe food means that food is harmless to consumers' health within the known knowledge, or harmful substances are at an acceptable or controllable level.
What did the older generation mean when they said I was a little dangerous?
If there is nothing specific to refer to. What the average old man means is that you may make a big mistake.
Definition of risk point in safety production?
1. Determine whether the key unit devices, storage facilities and electrical facilities have preventive and control measures.
Safety facilities with the execution function of controlling explosion, leakage and fire accidents (or
Device or standard) and improvement measures, and establish a list, implement the responsibility of management, maintenance and testing.
System.
2. Determine the material hazard characteristics and process hazard degree in the production area, and set them according to the work needs.
The highest fire-proof and explosion-proof level is designated as the safety control restricted area, which can prevent high temperature, open flame and static electricity.
Anti-collision, anti-friction, anti-short circuit and other measures are reliable to ensure that there is no open flame and no smoke.
For example, kindling is nothing more than explosion-proof electrical appliances and electronic equipment.
3. Whether the structures, facilities and equipment in use are fire-proof and explosion-proof, and judge the explosion.
After explosion, leakage and fire accidents, materials and other materials at the site may be produced in an accident state.
