Implementation.
6.2.3 Risks that may arise from each activity process
a. Survey Stage: After the surveying unit arrives at the site, the management personnel should identify the scope of responsibility of the project with relevant personnel and the occupational health and safety risks during the surveying process, for example:
——When crossing mountains and hills, passing through areas inhabited by animals, or measuring in underground caves and on cliffs.
——When conducting measurements in rivers, lakes, or at sea.
When lost in the dense forest valley due to difficulties in direction recognition and communication.
When the residence is close to the coast, a tsunami or typhoon occurs.
In existing line operations, when an instruction for a violation is issued.
——Traffic, environment, factories, underground pipelines, and safety of residential areas, etc.
b. Risks during the design phase, such as:
——Use of equipment safety performance, electrical safety, etc.
Workplace safety.
——Traffic safety for personnel travel.
c. Coordination of risks during construction, such as:

e. Identification of risks in overseas projects, for example:
——The risk of complying with the laws of the host country and local religious and cultural requirements.
The risk of attacks by criminals.
The risk of disputes arising from language barriers leading to group fights.
——Natural disaster risks brought by special regions and geographical environments.
6.2.4 Dynamic Identification of Hazard Sources
The following situations require a re-identification of hazards:
a. When affecting the achievement of occupational health and safety policy objectives (indicators).
b. When relevant laws, regulations, and other requirements are updated.
c. When there are changes in the scope of responsibility, products, processes, activities, or environment.
d. When relevant parties participate in activities or complete tasks;
e. When there are potential accident hazards and the identification of original danger sources and risk assessment are insufficient.
6.3 Risk Assessment
The appropriate method for risk assessment should be adopted, among which the "Operational Condition Hazard Analysis and Evaluation Method" is the LEC method:
6.3.1 Probability of Accident Occurrence (L)
The score for "the possibility of an accident occurring is extremely low" is set at 0.1, while the score for an event that is certain to occur is set at 10. The situations in between these two are several intermediate values, as shown in Table 1:
See Table 1:
(Table 1)
The likelihood of an accident (L)
| Score | Possibility of an accident occurring |
|
|
It can be completely anticipated |
|
|
Quite likely |
|
|
Possible, but not often |
|
|
Low possibility, completely unexpected |
|
|
Very unlikely, it can be imagined |
|
|
Highly unlikely |
|
|
Actually impossible |
6.3.2 Frequency of exposure to hazardous environments (E):
The occurrence of personnel in dangerous environments is set at 0.5 for very rare appearances; continuous appearances in dangerous environments are set at 10. Various situations between the two are assigned several intermediate values. See Table 2:
(Table 2)
Frequency of exposure to hazardous environments (E)
| Score | Frequency level |
|
|
Continuous exposure |
| 6 | Exposure during working hours every day |
| 3 | Weekly exposure or incidental exposure |
| 2 | Once a month exposure |
|
|
Several exposures each year |
| 0.5 | Extremely rare exposure |
6.3.3 Severity of Consequences That May Result from an Accident (C)
The score for minor injuries requiring rescue is set at 1; the score for the possibility of causing more than 10 deaths is set at 100, and the values for other situations are between 1 and 100. See Table 3:
(Table 3)
The severity of the consequences that may result from an accident (C)
| Score | Laws and Regulations and other requirements |
Casualties | Direct Economy Loss ten thousand yuan |
Work stoppage | Company Image |
| 100 | Serious violation of the law Regulations and Standards |
More than 10 people dead, or 50 Serious injuries above one person |
More than 5000 | The company has ceased production | Major international and domestic |
| 40 | Violation of laws and regulations and Standard |
More than 3 people, up to 10 people Death, or more than 10 people, Severe injuries under 50 people |
Over 1000 | Device or project suspension | Intra-industry, intra-province |
| 15 | Potential regulatory violations and Standard |
3 people or fewer died, or 10 Serious injury below the waist |
Over 100 | partial devices or Project work suspended |

Inside the company |
| 1 | Completely in line | No casualties | 1 Below | No work stoppage | Unaffected |
Note: The C value in this table can be satisfied by meeting any one of the conditions listed.
6.3.4 Determine the score values of the three parameters
For example, the hazard source determination score for "transformer struck by lightning causing harm to personnel":
L: The likelihood of an accident occurring
According to the protective conditions set on site, there are warning signs, and the distance from the ground is above 2 meters. Under normal conditions, it will not cause personal injury, with a score of 3.
E: Frequency of exposure to the environment
Based on the employee's exposure during the transformer lightning strike, the value is set to 1.
C: Severity of Consequences That May Result from the Accident
Due to the proximity of the transformer to the work area and flammable and explosive points, there is a possibility of triggering a chain disaster; therefore, the score is set at 15 according to the "Hazard Factor Evaluation Sample Table" QESP603R04.
By multiplying the three values mentioned above, the risk level danger score "D" can be obtained.
That is:
6.3.5 Evaluation of Score "D"
According to experience, a total score below 20 is considered low risk, even smaller than the risk of commuting by bicycle daily (see Table 4):
(Table 4)
Risk Level Table (D)
| Risk value | Risk Level | Actions to be taken (control measures) | Implementation period | |
| D
|
Level 1 | Extremely dangerous | Measures to reduce harm must be taken before proceeding Evaluate the improvement measures |
Immediately |
|
|
Level 2 | Highly dangerous | Take emergency measures to reduce risks and establish operational control Program, regular inspection, measurement, and evaluation |
Immediate or recent rectification |
| 70<D<160 | Level 3 | Significant danger | Consider establishing goals, creating operating procedures, and strengthening Training and Communication |
Governance during the target period |
|
|
Level 4 | Mild danger | It may be considered to establish operating procedures and work instructions, but Regular inspection required |
Item, have |
|
|
Level 5 | Slightly dangerous | No control measures are required, but records must be kept | 1 |
If the score is between 70 and 160, there is a significant risk that requires rectification; if the risk score is between 160 and 320, it is highly dangerous and immediate rectification is necessary, including the formulation of an emergency plan. A score above 320 indicates extreme danger, and production must be immediately halted, with measures put in place until the danger is eliminated.
The division of danger scores is based on experience and inevitably has limitations; it cannot be considered universally applicable and should be adjusted according to the situation when applied. When the evaluation result is
6.4 Release of Hazard Source List
The group company, based on the risk assessment results, has created the "Group Company Hazard Source Control List," marking "major hazard sources" (not specified by the state), which will be published and implemented after review and approval.
Relevant units should supplement and improve the list of hazardous sources related to their unit based on the group's hazardous source control list, especially for "major hazardous sources" (if necessary), forming their own hazardous source control list, developing control measures and emergency plans, and implementing control over the hazardous sources.
6.5 Control Measures
6.5.1 Classification of Control Measures
a. Requirements and protective (supervisory) measures for personnel responsibilities, capabilities, awareness, and education and training.
b. Take measures such as inspection, maintenance, replacement, and grounding of the equipment.
c. Confirmation, identification, and evaluation of software and spare parts (backups) to prevent erroneous operation.
d. Compliance with standard testing and specified requirements for material supply.
e. Re-evaluation of the process methods and necessary identification.
When environmental conditions cannot be rectified or need to be avoided, appropriate protective measures should be taken.
g. Other aspects: for example, focusing on genetic factors, defect issues, and the effectiveness of implemented measures, etc.
6.5.2 Control Measures Requirements
Major risk control should follow the principles of "elimination, prevention, reduction, isolation, and personal protection." For significant hazards related to this unit, emergency plans should be developed. Responsibilities, emergency measures, and necessary resource guarantees should be clearly defined, and drills should be conducted and recorded as needed.
6.5.3 Control methods for major hazard sources:
a. Establish control objectives;
b. Research whether it is possible to eliminate and prevent hazards;
c. Research whether engineering measures can be taken to reduce risks;
d. Establish control measures;
e. Training and Education;
f. Develop emergency response plans;
g. Strengthen on-site supervision and inspection.
