What do the types of safety hazards refer to

Question 1: What is a hidden safety hazard inspection I. Safety Inspection:

Any production process in an enterprise is accompanied by certain unsafe factors. In order to reduce the occurrence of production safety accidents, it is necessary to predict the possible occurrence of accidents of various unsafe factors (risk factors), for these unsafe factors, the development of preventive measures. The safety inspection and inspection of the use of safety checklist is to find unsafe factors (risk factors) means and tools, is the most basic, the most simple way to identify potential unsafe factors (potential risk factors).

The content of the safety inspection:

1. Check whether the enterprise has established and improved the production safety organization and production safety responsibility system, whether to implement the "five simultaneous" (i.e., in the planning, layout, inspection, summary and evaluation of production work at the same time, planning, layout, inspection, summary and evaluation of safety work), "Three simultaneous" (i.e., in the new construction, expansion, alteration projects, and safety precautions and protection measures at the same time design, construction, production and acceptance) on the investigation of casualties and the handling of accidents whether to adhere to the "four do not spare" (i.e., can not find out the cause) Not to let go, I and the masses of workers can not be educated not to let go, did not formulate corrective and preventive measures not to let go, corrective measures did not carry out the evaluation of the effect not to let go) of the principle of the enterprise rules and regulations (such as safety training, education system, all levels of responsibility, the safety of various types of operating procedures, etc.) is sound and perfect, whether strict enforcement of the standard of the enterprise safety and technical measures to fund the funds to ensure that there is no guarantee, and so on.

2. Check the production site environment and equipment, substances (raw materials and materials) state, that is, check the business environment and labor conditions, production equipment and the corresponding safety protection facilities are in line with the requirements of the safety standards, such as checking the various equipment, facilities, safe operation and maintenance of the Qian situation, checking the use of raw materials and toxic and hazardous gases, vapors, dust, etc. to trigger the preventive measures of safety accidents, checking the electrical, boilers, pressure vessels, various types of safety measures, and so on. Electrical, boilers, pressure vessels, the use of various industrial cylinders, check the flammable, explosive, materials and toxic and hazardous materials storage, transportation and use, check the use of personal protective equipment in line with safety standards, as well as ventilation, lighting, safety channels, safety exits and other operating environment, labor conditions in line with the relevant safety standards.

3. Check whether the enterprise operation workers have unsafe behavior, such as whether the operation workers operate according to the safety operation procedures of the relevant types of work, and whether the action of the operation meets the safety requirements.

From China's nearly 50 years of fatal accidents occurred in the statistical data, which due to the operation of workers in violation of operating procedures, misoperation and environmental conditions, equipment. Tools, accessories, process defects caused by casualties accounted for more than 60% of the total number of accidents, therefore, the focus of the safety inspection should be placed on the unsafe state of the material (including machinery and equipment, facilities, raw materials and materials used, etc.) and unsafe human behavior, to find out the unsafe factors (hazardous factors), and to take precautionary measures to rectify the safety.

Second, hidden trouble inspection:

Hidden trouble inspection refers to the production and management units in accordance with the unit hidden trouble inspection system to organize the relevant personnel to investigate the unit of hidden accidents; the investigation of hidden accidents to register, hidden accidents inspection and management of the implementation of the full coverage of the whole process management.

Hidden danger inspection and management standard is based on safety related laws, regulations, rules, standards, procedures and safety management system, combined with the industry characteristics of the production and operation units, extracted in violation of the provisions of the above laws, regulations, standards, rules, etc., and in the production and operation of activities in the existence of dangerous state of the material that may lead to the occurrence of accidents, unsafe human behavior and management deficiencies, by means of Hidden danger enumeration description item to realize the specific type of production and management unit hidden danger of the generalization.

The core content of the hidden danger investigation and management standard: first of all, it is necessary to carry out a reasonable classification of hidden dangers, classification is scattered in many laws, regulations, rules, standards, regulations and safety management system in the hidden danger description of the items of the induction, refining, and is the key to the organization of the core content of the hidden danger investigation and management standard. The classification of hidden danger is not only convenient for the production and management units to carry out the work of hidden danger self-investigation, but also conducive to the distribution of hidden danger of the production and management units for statistical analysis.

Relative to the standardization of safety assessment standards, hidden trouble detection and management standard is the specificity of its content, in the standardization of safety assessment standards, in the hidden trouble detection and management only put forward the basic requirements and principles of the provisions of the hidden trouble detection and management standards, hidden trouble in the description of the item is more detailed, detailed, operable. It can be seen that the hidden trouble detection and management standard is a further refinement and deepening of the standardization of work safety assessment standards, can be carried out for the enterprise ...... >>

Question 2: What is the difference between a hidden safety hazard and a hidden accident hazard? Hidden safety hazards: refers to the production and operation units in violation of Andan production laws, regulations, rules, standards, regulations, the provisions of the production safety management system, or other factors in the production and operation activities in the existence of unsafe conditions that may lead to the occurrence of unsafe events or accidents, human unsafe behaviors and management deficiencies. From the nature of the general safety hazards and major safety hazards.

Accident hazards, refers to human activities, equipment and facilities of the unsafe state, or due to human unsafe behavior and management deficiencies that may lead to personal injury or economic loss of the potential danger. Accident hazards are divided into general accident hazards and major accident hazards.

The difference between safety hazards and accident hazards is that accident hazards are a type of safety hazards. Safety hazards are broader in scope.

Question 3: What are the classifications of fire hazards (1) the building layout is unreasonable, easy to spread after a fire or affect the safety of other buildings;

Question 4: What is a safety production accident hidden danger? How to categorize safety accidents Hazard evaluation method (LEC method)

(1)

The operating conditions hazard evaluation method uses the product of three factors related to the system risk to evaluate the size of the risk of operator injury and death, these three factors are: L (the likelihood of accidents occurring), E (the frequency of exposure of personnel to hazardous environments) and C (the consequences of accidents that may result in the event of an accident). ). The criteria for assigning points are shown in the table below

Likelihood of an accident occurring (L)

Score value Likelihood of an accident occurring Score value Likelihood of an accident occurring

10 Completely predictable 0.5 Very unlikely, conceivable

6 Quite probable 0.2 Extremely unlikely

3 Possible, but infrequent 0.1 Practically unlikely

1 unlikely, completely unexpected

Frequency of Personnel Exposure to Hazardous Environments (E)

fractional value Personnel Exposure to Hazardous

Frequency of Personnel Exposure to Hazards in the Environment fractional value Personnel Exposure to Hazardous

Frequency of Personnel Exposure to Hazardous Environments in the Environment

10 Continuous Exposure 2 Monthly Exposure

6 Exposure During Daily Working Hours 1 Exposure several times a year

3 Weekly or occasional exposure 0.5 Very rare exposure

Likely consequences of an accident (C)

Score value Likely consequences of an accident Score value Likely consequences of an accident

100 Catastrophe, many deaths, or major property damage 7 Serious, serious injuries, or lesser property damage Small property damage

40 disaster, several deaths, or cause a lot of property damage 3 major, disability, or very small property damage

15 very serious, one death, or cause some property damage 1 compelling, not conducive to the basic safety and health requirements

(2) by the evaluation team experts **** with the determination of each source of each hazard of each of the points of the LEC (2) by the evaluation team experts *** with the determination of each hazardous source of each LEC points, and then the product of the three points to evaluate the size of the hazardousness of the operating conditions, that is:

D = LEC

(3) will be the D value and the classification of hazardous classification standards in the points compared to the classification of the risk level, if the D value is greater than 70 points, it should be designated as a major source of risk,. The evaluation of the hazardous source is filled in the "Evaluation Form of Hazardous Sources (LEC Method)".

Risk classification based on risk value D

Score value risk level degree of danger

Greater than 320 first-class extremely dangerous, can not continue to operate (to develop management programs and emergency plans)

160-320 second-class highly dangerous, to be immediately rectified (to develop management programs and emergency plans)

70-160 Class III significant danger, need to rectify (preparation of management plan)

20-70 Class IV general danger, need attention

Less than 20 Class V slightly dangerous, acceptable

Whether it is the expert scoring method or the LEC method, the classification of the danger level is based on empirical judgments, it is inevitable that there are limitations, and the application of the application should be revised according to the actual situation.

Question 5: What is the difference between a safety risk and a safety hazard, with examples Safety risk:

Traditionally, there have been two approaches to safety risk management: the forward-looking approach and the reactive approach, each with its own advantages and disadvantages. There are also two different approaches to prioritizing a particular risk: qualitative safety risk management and quantitative safety risk management.

Approaches to Risk Management

Many organizations introduce security risk management by responding to a relatively small security event. But regardless of the initial incident, as more and more security-related issues arise and begin to impact the business, many organizations become discouraged from responding to one crisis after another. They needed an alternative approach, one that would reduce the number of first security incidents. Organizations that manage risk effectively have developed a more forward-looking approach, but this approach is only part of the solution.

Reactive approach: When a security incident occurs, many IT professionals feel that the only viable option is to contain the situation, point out what happened, and fix the affected systems as quickly as possible. A reactive approach can be an effective technical response to a security risk that has been exploited and converted into a security incident, giving a reactive approach a degree of rigor that can help all types of organizations make better use of their resources.

Forward-looking approach: forward-looking security risk management has many advantages over the reactive approach. Unlike waiting for something bad to happen and then responding, a forward-looking approach minimizes the likelihood of something bad happening in the first place.

Of course, organizations should not abandon incident response altogether. An effective forward-looking approach can help an organization significantly reduce the number of security incidents that occur in the future, but it seems that such problems don't go away completely. Therefore, organizations should continue to improve their incident response processes while developing a long-term forward-looking approach.

Safety hazards:

Safety hazards refer to the hazardous state of objects, unsafe human behavior, and management deficiencies that may lead to unsafe events or accidents in production and operation activities. From the nature of the division into general safety hazards and major safety hazards.

Question 6: How to divide the general hazards and major hazards General hazards are less hazardous and do not cause major personal injury and major economic loss of safety hazards.

Major safety hazards are those that may lead to major injuries or major economic losses.

The major safety hazards are divided into two levels according to the unsafe state of the workplace, equipment and facilities, unsafe human behavior and management deficiencies, which may lead to the degree of accidental loss:

(1) the particularly significant safety hazards refers to the safety hazards that may result in the death of more than 50 people or may cause a direct economic loss of more than 10 million yuan;

(2) major safety hazards refers to the safety hazards that may result in the death of more than 50 people or may cause a direct economic loss of more than 10 million yuan;

(2) major (2) Major safety hazard means a safety hazard that may cause more than 10 deaths or may cause a direct economic loss of more than 5 million yuan

Question 7: What is a hidden accident A hidden accident refers to the unsafe state of the workplace, equipment and facilities, the unsafe behavior of people and management deficiencies, and is the direct cause of safety accidents. Major accident hidden danger refers to the accident hidden danger that may lead to major casualties or major economic losses, and strengthening the control and management of major accident hidden danger is of great significance for the prevention of large-scale safety accidents.In 1995, the former Ministry of Labor promulgated the "Major Accident Hidden Danger Management Provisions", which makes specific provisions for the assessment, organization and management of major accident hidden danger, and rectification and rectification requirements. Concepts and Components of Major Accident Hazards and Major Danger Sources. Hidden accident hazards and sources of danger are not equivalent concepts. Hidden accident hazards refer to the unsafe state of workplaces, equipments and facilities, unsafe human behaviors and management defects. It is essentially a dangerous, unsafe, defective "state", this state can be manifested in people or things, such as people walking unsteadily, the road surface is too slippery are leading to falls and injuries; can also be manifested in the management of the program, content or mode, such as inspection is not in place, the system is not sound, personnel training is not in place. Hazardous source refers to a system with potential energy and material release danger, can cause injury, property loss or environmental damage, in a certain trigger factor can be transformed into an accident parts, areas, places, spaces, positions, equipment and its location. Its essence is a potentially dangerous source point or site, is the source of the outbreak of accidents, is the core of the energy, hazardous substances concentrated, is the energy from there out or outbreak of the place. Hazardous sources exist in defined systems, and the area of a hazardous source varies from system to system. For example, on a national scale, for hazardous industries (e.g., petroleum, chemical, etc.) a specific enterprise (e.g., refinery) is a hazard source. And from an enterprise system, may be a certain workshop, warehouse is a source of danger, a workshop system may be a certain piece of equipment is a source of danger; therefore, the analysis of sources of danger should be carried out according to the different levels of the system. Generally speaking, the source of danger may or may not exist accident potential hazards, for the existence of accident potential hazards of the source of danger must be rectified in a timely manner, otherwise at any time may lead to accidents. In practice, the control and management of hidden accident hazards are always associated with a certain source of danger, because there is no danger of hidden danger can not talk about to control it; and the control of the source of danger, in fact, is to eliminate the existence of hidden accident hazards or to prevent the emergence of hidden accident hazards. Therefore, in practice, these two concepts are sometimes used without distinction. According to the above definition of the source of danger, the source of danger should be composed of three elements: potential danger, existence conditions and triggering factors. The potential danger of a hazardous source refers to the degree of harm or the size of the loss that may be brought about by an accident once it is triggered, or the intensity of the energy that may be released by the source or the size of the quality of the hazardous material. The existence conditions of the hazardous source refers to the physical and chemical state and the state of constraints in which the hazardous source is located. For example, the pressure, temperature, and chemical stability of the substance, the sturdiness of the pressure vessel containing it, and the condition of the surrounding environmental obstacles. Trigger factors are not inherent properties of the source, but it is a source of danger into the external cause of the accident, and each type of hazardous source has a corresponding sensitive trigger factors. Such as flammable, explosive substances, heat is its sensitive trigger, and such as pressure vessels, pressure rise is its sensitive trigger. Therefore, a certain source of danger is always associated with the corresponding trigger factors. Under the action of the trigger factor, the source of danger into a dangerous state, and then into an accident.

Question eight: repair shop three violations of what they exist in the category of safety hazards This seems not to be a car repair problem Oh, run the question, I wish you a happy life car problem, ask the car master. 4S store professional technician, 10 minutes to solve.

Question 9: What are the safety hazards on the construction site This is a list of major hazards identified on a typical construction site, you can refer to it.

Question 10: What is a safety hazard appliance? Is there any national specification or categorization? It is not right to be so vague on the part of the hostel management, and you should be clearly explained to you. In addition there is no right to confiscate your compensation.

You buy electrical products, if it is a regular manufacturer, there are trademarks, manuals, product certificates, three packs of certificates and electrical certificates, such as ccc (China standards), CE (European standards), UL (U.S. standards), then it can be considered that the appliances themselves are safe.

But hairdryers also belong to high-power appliances, which may have an impact on the line load.

So the above factors are the basis for measuring whether the appliance is safe or not.
