< method examples >

Fig. 1 shows a schematic flow diagram of a method for dynamic staging of scaffold operational risk according to an embodiment of the present disclosure. As shown in fig. 1, the method includes steps S1100-S1300.

And S1100, determining at least two engineering indexes for evaluating operation risks according to a pre-constructed scaffold operation risk grading index system.

Before the scaffold operation risk classification is carried out, risk analysis is carried out by adopting a set risk analysis method according to accident cases and risk events of scaffold operation in nuclear power engineering so as to determine risk factors and safety factors of scaffold operation.

The accident cases include scaffold collapse, high fall, object strike, etc. The collapse accident of the scaffold can be divided into a whole instability collapse accident of the scaffold and a local collapse accident of the scaffold according to the collapse degree. Scaffold frame eminence accident of falling divide into according to the object of falling that scaffold frame takes and tears operation personnel eminence accident of falling and scaffold frame on constructor eminence accident of falling. The scaffold object striking accidents comprise accidents of casualties and property loss on the scaffold or on the adjacent ground caused by falling of objects on the scaffold.

The risk event refers to a causal event causing accidents and losses, including direct causes and indirect causes. Risk events of scaffold operation in nuclear power engineering can be divided according to accident types, and the risk events in high-altitude falling accidents comprise safety belt damage, insecure safety belt fastening, safety helmet damage, unreasonable edge protection setting, improper safety supervision and the like. The risk events in the event of a collapse of a scaffold include disqualification of scaffold erection material, exceeding of the scaffold height specification, oversizing of the scaffold base unit or removal of part of the base frame bars, etc.

The risk factors may include weather conditions (rainfall, lightning, strong winds), engineering environment (temperature, noise, lighting, scaffold vibration), scaffold height, material placement on scaffolds, etc. In order to ensure the construction safety, some necessary safety control measures are required, including high-altitude falling protection facilities, fire protection facilities, safety protection appliances and the like.

The safety factors may include factors of people working on the scaffold and factors of construction safety management, safety education delivery, construction preparation, etc. During the operation of the scaffold, if the preparation work of safety factors is insufficient or has defects, the risk event can be caused.

The set risk analysis method may be an accident tree analysis method, a BowTie analysis method, or a safety check list-based analysis method, and is not limited specifically herein.

For example, in the case of an accident that people fall from a high place on the scaffold together, the accident tree analysis method is adopted to perform risk analysis, and the analysis result shown in fig. 2 is obtained. And after the analysis result is obtained, analyzing the structural importance of each factor in the accident tree, and taking the factor of which the structural importance meets the set requirement as a risk factor and a safety factor of the scaffold operation. Wherein the risk factors and safety factors include: safety guardrails, safety belts and safety ropes are not arranged at construction positions or are not sufficient; the operation personnel work against the rules and regulations, improper operation, poor safety consciousness, no safety belt fastening and no safety helmet wearing; the strength of the scaffold is insufficient; excessive materials are stacked, the equipment is lifted to work with diseases, and risk factors and safety factors such as maintenance and repair are avoided.

When determining the risk factors and safety factors of scaffold operation, the determination may be performed according to accident cases and risk events of multiple scaffold operations, or typical accident cases or risk events may be selected together for determination, which is not specifically limited herein.

After the risk factors and the safety factors of the scaffold operation are determined, grading indexes for grading the scaffold operation risk can be screened from the determined risk factors and safety factors, and all the grading indexes are classified.

In a possible implementation manner, after classifying all the classification indexes, at least one type of classification indexes of an operator classification index, an operation equipment classification index, an operation environment classification index and an operation management classification index is obtained, and a scaffold operation risk classification index system is constructed based on different index types.

In a possible implementation manner, when the scaffold operation risk classification index system is constructed based on different index types, a plurality of levels are correspondingly divided for each index type. The number of the divided layers can be determined according to a specific application scene.

In one possible implementation, each index type is divided into three levels.

The primary indicators for the operator include: human factors. Secondary indicators of factors about the person include: at least one of safety protection, mental state of personnel, field work conditions, and experience of personnel. Three level indicators for the safety protection article include: at least one of a safety helmet, a safety harness, and a tool bag. Three levels of indicators about the mental state of the person include: at least one of heart rate and blood pressure. Three levels of indicators regarding the field operation condition include: at least one of the work time and the number of persons working. Three levels of metrics on the human experience include: at least one of operator experience and manager experience.

The primary indicators regarding the work equipment include: the factors of the substance. Secondary indicators of factors related to the object include: at least one of scaffold components, protective gear and scaffold scale. The three-level metrics for the scaffold components include: at least one of a steel pipe, a cross brace setting condition, a throwing brace setting condition, a fastener and a base plate. The three-level metrics for the protective facility include: at least one of a limb protection, a dense mesh net, an anti-falling net and a fire-fighting equipment. The tertiary metrics on the scaffold scale include: at least one of the placement condition of the materials on the scaffold and the height of the scaffold.

The primary indicators regarding the operating environment include: environmental factors. Secondary indicators for the environmental factors include: at least one of a meteorological environment and an engineering environment; . Three levels of indicators about the meteorological environment include: at least one of wind speed, lightning, and rain. Three levels of metrics relating to the engineering environment include: at least one of temperature, noise, scaffold vibration, and lighting.

The primary metrics for job management include: and (4) managing factors. Secondary metrics for the management factors include: the safety management personnel configure at least one of the conditions, safety education and training conditions, emergency drilling and plan, engineering scheme and safety technology interaction. The three-level indicators regarding the safety education and training situation include: at least one of a safety education and training plan and a safety education and training frequency. The three-level indexes related to the emergency drilling and the plan comprise: at least one of an emergency drill effect and an emergency plan completeness.

For example, a scaffold operation risk classification index system constructed according to the above method may be as shown in table 1.

TABLE 1

After the scaffold operation risk classification index system is constructed, at least two engineering indexes for evaluating operation risks can be determined according to the constructed scaffold operation risk classification index system. Specifically, all final-stage indexes in the scaffold operation risk classification index system may be used as engineering indexes for evaluating operation risks, or at least two final-stage indexes may be selected as engineering indexes for evaluating operation risks, which is not specifically limited herein. Wherein the final-stage index refers to a classification index without further division. For example, the safety manager configuration, the engineering scheme, and the safety technical background in all the three-level indicators and the two-level indicators in table 1 are final indicators.

S1200, acquiring the comprehensive weight value and index score of each engineering index, and calculating to obtain a comprehensive evaluation value of the scaffold operation risk according to the comprehensive weight value and index score of each engineering index.

The comprehensive weight value of each engineering index is the weight value of each engineering index relative to the cascaded first-level index. In one possible implementation manner, steps S1210 to S1220 are included in obtaining the comprehensive weight value of each engineering index.

And S1210, acquiring the weight value of each engineering index in the scaffold operation risk classification index system and the weight value of the cascade index in each level to which each engineering index belongs by adopting a hierarchical analysis method.

For all grading indexes of all levels in the scaffold operation risk grading index system, a comparison matrix of each level can be determined in a pairwise comparison mode, and then the weight value of each grading index in each level is determined according to the comparison matrix of each level.

Because the engineering index is the final-level index selected from the scaffold operation risk classification index system, the weight value of each engineering index can be determined under the condition that the weight value of each classification index is determined. For example, if the weight value of the safety helmet as the three-level grading index in table 1 is C1, the weight value of the safety helmet as the engineering index is also C1.

And the weight value of the cascade index in each level to which each engineering index belongs is the corresponding weight value obtained by the analytic hierarchy process. For example, in table 1, the cascade index in the second level to which the safety helmet belongs is a safety protection article, the cascade index in the first level to which the safety helmet belongs is a human factor, and the weight value B1 of the safety protection article and the weight value a1 of the human factor are obtained by using an analytic hierarchy process.

And S1220, acquiring a comprehensive weight value of each engineering index according to the weight value of each engineering index and the weight value of the cascade index in each level to which each engineering index belongs.

In a possible implementation manner, the weight value of each engineering index and the weight value of the cascade index in each level to which each engineering index belongs may be multiplied to obtain a comprehensive weight value of each engineering index. For example, the combined weight value D1 of the helmet is a1 × B1 × C1.

Before the index score of each engineering index is obtained, the engineering indexes are graded according to the risk influence degree of each engineering index on the scaffold operation, and the grading standard and the corresponding index score of each engineering index are determined to obtain a grading table corresponding to each engineering index.

For example, the temperatures are classified into 4 classes according to the degree of the risk influence of the temperatures on the scaffold work, and the obtained class classification table corresponding to the temperatures is shown in table 2.

TABLE 2

In order to conveniently and dynamically obtain the index score of each engineering index, a risk dynamic classification table can be constructed according to the grade classification table corresponding to each engineering index. The risk dynamic grading table comprises the division standard of each grade of each engineering index and the value range of the corresponding index score.

In one possible implementation, the constructed risk dynamic ranking table may be as shown in table 3.

TABLE 3

Under the condition of obtaining the risk dynamic grading table, the value of the index score of each engineering index can be determined in the value range corresponding to each engineering index according to the actual condition of scaffold operation. The value range can be set in a percentage mode, a tenth mode or a fifth mode. In one possible implementation, the value range is set according to a five-division method, and a five-division method can be adopted when a standard value range is set for each engineering index. Each division standard sets a corresponding value score in a five-score system.

For example, in the scaffold operation process, if a constructor correctly wears a safety helmet and the worn safety helmet is intact, the value of the index score of the engineering index, namely the safety helmet, can be determined to be 1 according to table 3; if the safety helmet worn by the constructor is intact, but the wearing mode of the safety helmet is incorrect, the value of the index score of the engineering index of the safety helmet can be determined to be 2 according to the table 3.

In the implementation mode, the index values of all engineering indexes can be dynamically acquired through the constructed risk dynamic grading table, so that the timeliness and the accuracy of the scaffold operation risk grading can be improved.

In a possible implementation mode, when a comprehensive evaluation value of the scaffold operation risk is obtained through calculation according to the comprehensive weight value and the index score of each engineering index, the comprehensive evaluation value is obtained through calculation by adopting a pre-constructed risk classification model; wherein the risk classification model is constructed based on penalty factors formulated for human, equipment and environmental factors. Because a plurality of punishment factors which are set aiming at human factors, equipment factors and environmental factors are adjusted according to the dynamic condition of scaffold operation, the risk classification model can dynamically reflect the scaffold operation risk, and the timeliness and the accuracy of risk classification are further improved.

In one possible implementation, the risk classification model may be represented as follows:

in the formula, j, k and l are punishment factors corresponding to weights, the sum of the weights is 1, M is the total number of the operation, M is the number of the illegal operation, M is the total number of the operation, and n is the number of the fault equipmentQuantity, N is the total equipment quantity, B is the risk environment factor quantity, B is the total environment factor quantity, D is the comprehensive evaluation value of the scaffold operation risk,

And S1300, determining the risk level of the scaffold operation risk according to the comprehensive evaluation value.

Before determining the risk level of the scaffold operation risk, a risk level division standard based on a comprehensive evaluation value needs to be established.

In one possible implementation, the risk ranking criteria based on the composite rating value may be as shown in table 4.

TABLE 4

If the obtained overall evaluation value is (0,4), the risk level of the scaffold work risk is first, and in this case, the safety situation is particularly serious. If the obtained comprehensive evaluation value belongs to (4,8), the risk level of the scaffold operation risk is two-level, and in this case, the safety condition is serious. If the obtained overall evaluation value belongs to (8,16), the risk level of the scaffold work risk is at three levels, and in this case, the accident is at the rising stage. When the obtained comprehensive evaluation value belongs to (16,32), the risk level of the scaffold operation risk is four, and the production activity is in a normal state.

After the risk level of the scaffold operation risk is determined, corresponding operation can be executed according to the risk level, and then the accident is avoided being released or the loss caused by the accident is reduced.
