Common sense of safety

Emergency warning types: red warning (especially serious), orange warning (serious), yellow warning (heavy), blue warning (general)

to evaluate the situation of hazard control, the following aspects should be considered: 1) the ability to prevent human error2. The ability to control the consequences of mistakes; 3. Ability to prevent failure transmission; 4. The difficulty of accidents caused by mistakes or faults

there are two situations when dangerous substances exceed the critical quantity: one is when the quantity of a dangerous substance in the unit reaches or exceeds the critical quantity, and the other is when the sum of the ratio of the quantity of various dangerous substances in the unit to its critical quantity is greater than 1

hazard source control

the safety countermeasures to prevent accidents are as follows:

1. eliminate hazard sources2. Limiting energy or hazardous substances; 3. 1solation

the safety technologies to avoid or reduce accident losses are as follows:

1. isolation2. Refuge and rescue

General hazard sources are composed of three elements: potential hazard, existing conditions and trigger factors

safety aphorism:

discipline is by no means the cage and chain of restricting freedom, but the system is the solid track of safety and happiness

take an umbrella to prevent rain when going out, and comply with regulations to prevent accidents

you show mercy for the violation of rules and regulations, and the accident shows no mercy to you

major hazards and hazardous factors refer to those that can lead to major accidents. Major hazard sources refer to the equipment and facilities with objectively existing hazardous substances or energy exceeding the critical quantity. Major accident hidden danger refers to the potential accident hazards that may cause death of more than 10 people, direct economic loss of more than 5 million yuan, or significant social impact in the process of production and operation

according to GB 18218-2000, major hazard installations refer to units (including places and facilities) that produce, handle, use or store dangerous goods for a long time or temporarily, and the quantity of dangerous goods is equal to or exceeds the critical quantity. Generally speaking, unit refers to a production unit, facility or place, or several production units, facilities or places that belong to the same factory and whose edge distance is less than 500 meters

once major hazard accidents occur, they are often catastrophic accidents such as fire, explosion, poisoning and so on< According to GB 18218-2000, major hazard installations are classified as follows: major hazard installations in production site and storage area there are four types of substances: 1. Explosive substances2. Flammable substances, 3. Active chemical substances, 4. Toxic substances the hazard level of major hazard installations is generally leve4, namely level 1 major hazard installations (R ≥ 200m), level 2 major hazard installations (100m ≤ r < 200m), level 3 major hazard installations (50m ≤ r < 100m) and level 4 major hazard installations (r < 50m), Here R is the radius of death possible disaster forms of major hidden dangers: catastrophic fire accident; Serious traffic accidents; Major construction quality and safety accidents; Major safety accidents of civil explosives and dangerous chemicals; Major safety accidents in coal mines and other mines; Major safety accidents of boilers, pressure vessels, pressure pipelines and special equipment, and other major safety accidents possible disaster forms of major hidden dangers: catastrophic fire accident; Serious traffic accidents; Major construction quality and safety accidents; Major safety accidents of civil explosives and dangerous chemicals; Major safety accidents in coal mines and other mines; Major safety accidents of boilers, pressure vessels, pressure pipelines and special equipment, and other major safety accidents safety evaluation method: safety evaluation method refers to the way, means or method to evaluate the safety of the system by using relevant scientific principles and practical experience. There are many safety evaluation methods, such as: 1. Fuzzy comprehensive evaluation method2. Material risk index evaluation method; 3. Dangerous material scoring method; 4. Working condition risk scoring method; 5. System safety basic scoring method; 5. Safety aphorism; 4. 1gnoring safety production is a way to get a chestnut from the fire; Seeking benefits without safety is like fishing for the moon in the water good people do harm to people and give the green light to accidents. One measure is better than ten slogans the methods of safety inspection include regular inspection, regular safety inspection, professional safety inspection and mass inspection classification of safety and health inspection: (1) statutory inspection: inspection conducted in accordance with the requirements of safety and health laws(2) External inspection: carried out by law enforcement, insurance and consulting units(3) Administrative inspection: inspection by superior management personnel(4) Routine inspection: carried out by the supervisor according to the plan within an appropriate period of time(5) Commissioning inspection: new or re commissioning equipment inspection(6) Continuous inspection: conducted by workers and supervisors. 1t can be formal, planned or informal before any inspection, the following important issues should be specified: (1) which items need to be inspected; (2) which aspects of the items listed in the table need to be inspected; (3) what kind of status needs to be inspected; (4) how long does it need to be inspected; (5) who will conduct the inspection follow the following ideas, 1t will help to improve the inspection technology: (1) necessary knowledge and experience; (2) develop and use the applicable checklist; (3) take notes; (4) be good at consulting and applying the archived report; (5) be good at thinking and asking questions; (6) be good at finding and tracking; (7) correct the danger at any time; (8) do quantitative test as much as possible (9) (10) inspection risk assessment main productive harmful substances the main productive harmful factors that may exist in the production environment can be summarized as: (1) productive poisons(2) Production dust(3) Abnormal climatic conditions(4) Radiation line(5) High pressure and bottom pressure(6) Productive noise and vibration the teaching forms of safety course include: report type safety course, audio-visual safety course, question answering safety course, seminar type safety course, lecture type safety course, forum type safety course, visit type safety course, competition type safety course, experimental type safety course and comprehensive type safety course categories of safety and health training: (1) induction training for new workers or transferred employees(2) Operation training(3) Supervisor and manager training< (4) special professional and technical training safety education for returning to work refers to the safety education before returning to work after work injury, recovery from illness or after a long holiday. The objects of return to work education include those who have recovered from work-related injuries and those who have been on leave for more than three months. There are: (1) safety education after work injury(2) Return to work safety education after vacation “five new” safety education “five new” safety education refers to the safety education of new operation methods and new jobs before the adoption of new processes, new technologies, new materials, new equipment and new products< How to improve safety education and training< 1t is necessary to establish and develop the position of safety education2. Safety education should be regular; 3. The educational methods should be flexible, vivid and avoid empty preaching; 4. Education should be carried out in combination with accident prediction and prevention. 5. Safety education system should be established and improved; 6. We should study people's psychology and personality; 7. To compile teaching materials suitable for various needs; 8.
