how to effectively control the personal safety risks in the outsourcing construction of substations
1. Strengthen the qualification examination of the construction workers entering the station. All the pit workers must have the qualification certificate for power grid access, have participated in the training of safety operation procedures and passed the examination, and have received certain basic knowledge training of electric power. Strictly check, all personnel who do not have relevant job qualifications and do not meet the requirements of pit stop work shall not be arranged to enter the substation to participate in the work, and the entry of dangerous sources shall be controlled from the source to reduce the possibility of safety accidents.
2. Before the operation starts, carry out the risk analysis of each link of the operation in advance, identify the harmful factors that may lead to accidents during the operation, and formulate effective control measures, write the control measures into the construction plan or formulate a special risk pre-control table to ensure that the pre-control measures are in place. Set the safety layout of the construction site reasonably before the work, and do a good job of early warning of dangerous points. First, before the formal construction, the staff should use fences to isolate the working place from the live device according to the power outage range, make a good layout of the construction site, clearly mark the field operation area in the construction site, and work out the basic route of the field operation, etc., to prevent some staff from blindly entering the execution device area and causing various safety problems; Second, the staff should analyze all the risk points on the construction site, mark them on the site, such as setting up warning signs, etc., to remind all the staff to pay attention to various problems that may exist in the construction process, so that they can be "aware", so as to eliminate or reduce the potential safety hazards in the working environment.
3. Standardize the on-site operation process, improve the safety awareness of relevant personnel, standardize the work of each construction link, take safety precautions for each process in strict accordance with the requirements of the construction plan, make safety technical disclosure, and improve the safety quality of staff. Construction enterprises should strengthen the safety quality education and training of staff, improve their ability to prevent safety risks, and at the same time, they must provide all necessary safety precautions and protective articles for construction personnel to avoid all kinds of safety accidents as much as possible.
4. Improve the safety risk management of the implementation project, and earnestly implement the safety monitoring system of all kinds of construction sites. The person in charge of the work and the designated work guardian must earnestly perform their safety monitoring duties, discover the dangerous behaviors that may occur during the operation, and stop the behaviors that violate the operation specifications and endanger the production safety during the construction process to prevent the occurrence of safety accidents. The safety management department shall set up an on-site inspection team to carry out surprise safety inspection on the construction site from time to time. Once safety management problems are found, the supervisors shall immediately stop the construction, arrange on-site rectification immediately, and investigate the responsibility of the corresponding person in charge, and are not allowed to resume operations before the problems are solved.
in addition, each substation construction unit must strengthen safety management communication and exchange with enterprises in the same industry, learn from their experiences in safety risk management and control in the construction process, and formulate a set of practical risk prevention or strategies in combination with their own actual situation. What are the personal safety risks of power field construction operations?
Personal safety risk control at the construction and maintenance operation site is an important work of safety production. First, it is necessary to implement the safety responsibilities of personnel at all levels from the organization; Secondly, operators should raise their awareness ideologically, actively implement various requirements of safety production, and conscientiously implement various safety measures at the job site. This paper introduces some measures adopted in practical work to control personal safety risks at the job site, and describes in detail the safety control at the power emergency repair site under bad weather conditions. How to prevent the safety risks in the construction site
The risks in production safety can be divided into four categories: people, things, environment and management. The corresponding control measures are divided into three categories: engineering technical measures, management measures and individual labor protection measures.
construction covers a wide range. digging a ditch and leveling a site is also construction, so is building a house and the whole community, and so is building roads and bridges. The security risks in each category are very different. The risks of the same kind of construction are different due to different environments. Therefore, we must control different risks.
Common engineering technical measures include elimination, substitution, dilution and isolation. Management measures include many inspection and monitoring, education and training, inspection and hidden danger management, warning and notification, emergency management and so on. Individual labor protection is mainly the distribution and standard wearing of labor insurance articles.
it's still a phrase I often say, concrete analysis of specific problems. What's the scene like? What risks are there? I can't know them online. I can only talk about the theoretical things and talk about a train of thought. According to the risks existing in the site, at least the control measures should be implemented according to the requirements of national laws, regulations and standards. According to the enterprise's own strength (Qian Qian's problem)
For example, for a specific construction site, there is a pile of sand around it. Whether to warn the pile of soil, pull the warning line, or support the foundation, or directly pull it away depends on the various conditions on the site. For another example, whether to draw a safe passage at the construction site and to what extent all kinds of visualization are done need to be done according to the requirements of the enterprise itself. Whether education and training is to speak a few words on the spot or to give lectures specially depends on the specific situation. Whether there are major hazards around the construction site, whether it is near the river and whether it is working in mountainous areas needs to be considered.
analyze and identify risks in a word, and implement control measures according to the standards. How to divide the operation tickets A and B for substation construction
Hello,
Open again. Only after this loop is disconnected with a switch can it be allowed to open the wrongly connected isolating switch.
6. When the disconnector is pulled by mistake, if it is a single-phase disconnector, one phase should be completely disconnected, but the other two phases should not continue to operate.
(III) Common fault treatment of transformer
1. When the indication of the instrument is wrong due to the fault of the transformer or its secondary circuit, the device should be monitored as far as possible according to the instructions of other instruments, and the execution mode of the device should not be changed as much as possible.
2. When the secondary circuit of the current transformer is found to be disconnected, try to short-circuit it on the terminal near the current transformer. If it is impossible, the current transformer should be stopped.
3. If the insulation on the high voltage side of the transformer is damaged or smoke is found in the current transformer, how to control the construction risk of the power enterprise by using the switch
Abstract: At present, people have put forward higher requirements for the safety and reliability of power supply, and how to stably and safely implement the power system is becoming increasingly important. How to systematically discover the unsafe factors in the construction of electric power enterprises, eradicate the hidden dangers of accidents and greatly reduce the accident rate is a new situation and new problem facing our safety management. Electric power enterprises have done a lot of work to improve the management level of safety production, such as investigating and analyzing power production accidents, regularly carrying out seasonal safety inspections and double-standard activities of safe and civilized production, etc., and achieved good results. However, these management methods have their own emphases and limitations in the implementation process, which makes the power enterprises have little effect in the ability to foresee and control accidents in advance. The main manifestations are as follows: some units have a good foundation of safety management and good inspection before the accident, but many problems have been exposed after the accident, and the problems have existed for a long time, and it is entirely possible to find and eliminate them in advance; Some units feel that the situation of safety production is grim and tense, but they don't know which soil fertility is most prone to accidents and what kind of accidents occur, and there are countless in their hearts; Other units have a long safety record, but their safety management level is average.
Facing the fierce industry competition environment in the power engineering construction market, power construction enterprises should fully realize the importance of safety management in power engineering project construction and the safety benefits brought by power engineering project construction safety to enterprises. How to do a good job in the safety management of power engineering construction is a problem worthy of in-depth analysis.
1. Importance of safety management in electric power engineering construction
Safety management in electric power engineering construction is a subsystem of project management. It is based on the implementation mode of "planning, implementing, checking and improving" dynamic loop mode (PDCA dynamic loop mode), and guides enterprises to systematically achieve the set goals of safety management with the idea of gradual improvement and continuous improvement. Therefore, construction safety management is a dynamic, self-adjusting and self-adjusting. The implementation of safety management in the process of power engineering project construction can improve safety benefits, which is the main embodiment of the importance of safety management.
2. Safety management of electric power engineering construction
1. Adhere to the policy of "safety first, prevention first and comprehensive treatment"
Adhering to the policy of "safety first, prevention first and comprehensive treatment" and strengthening the safety awareness of the whole construction process, all directions and all employees is the core of safety management on the construction site. Managers at all levels of enterprises should fully understand the important guiding spirit of "hidden dangers are more dangerous than open flames", "prevention is better than disaster relief" and "responsibility is more important than Mount Tai", understand the importance of doing a good job in construction safety for enterprises, projects and individuals, and conscientiously implement the policy of "safety first, prevention first and comprehensive management" with a high sense of work responsibility. By carrying out various safety training and education activities, such as safety warning education and accident case analysis, all employees of the enterprise can firmly establish the idea of "safety first" and the safety concept of "all accidents can be prevented", and combine safety education and training with ideological education, technical education and post professional training to improve safety awareness and self-protection ability.
2. Establish and improve the safety guarantee system of the construction site
As a multi-job operation group, the electric power engineering construction site is the foundation and guarantee for doing a good job in construction safety. The management idea of safety production guarantee system should be: clear responsibilities, prevention first, grasping key points, starting from the beginning to the end, and closed management. That is to guide the construction unit to implement various safety laws and regulations in the production process, implement standard management, clarify the functions of the safety production guarantee system from the project manager to the operators, and strengthen the responsibility system for safety production of personnel at all levels. At the same time, it is necessary to change the focus on material investment in safety production to investment in management resource development, and formulate corresponding preventive measures from various aspects such as people, finance, materials, machinery, law, science and environment through safety planning. From post-event treatment to pre-event control, it truly reflects the guiding ideology of putting prevention first, rationally allocates and clarifies the permission rights of departments and personnel at all levels, formulates various nodes, and formulates security plans for dangerous and key points, which fundamentally changes the situation that security measures in construction organization design are not targeted. Grasp from the source and implement closed management.
3. Safety management of electric power construction site
(1) Establish an emergency plan for electric power engineering construction
The purpose of preparing a plan at the construction site is to prevent and control the injuries of construction workers from being quickly responded when accidents occur during construction operations, minimize the injuries of personnel, and get organized emergency treatment in the shortest time.
in the electric power construction site, the main plans should include: emergency plans for fire accident handling; Emergency plan for hazardous chemicals; Emergency plan for mechanical devices; Emergency plan for radiation accidents; Emergency plan for food poisoning; Emergency plan for typhoon prevention and flood control; Emergency plan for casualty accidents, etc.
the content and format of the emergency plan shall be standardized (including laws, regulations and standards for safety production and environmental protection, relevant program files, list of hazards and list of environmental factors, etc.) to ensure the scientificity, pertinence, effectiveness and operability of the emergency plan preparation. Establish an emergency rescue system, set up an emergency rescue leading group, equip necessary emergency rescue equipment and devices, and organize relevant departments to carry out regular maintenance to ensure normal operation. After the preparation of the emergency plan is completed, the relevant departments shall conduct a professional audit of the emergency plan and sign it. It should be pointed out that the emergency plan is a guide to organize rescue operations for specific accidents. Therefore, there should be an exercise plan for the emergency plan, and regular exercises should be organized to verify the effectiveness of the emergency plan and response.
(2) Identification of hazardous factors in power engineering construction
Strengthen occupational safety and environmental protection factors in the construction site, evaluate their risk degree, determine general hazards and major hazards, and determine major hazards and major environmental factors, so as to provide scientific basis for the safety of operators and effectively control them. Hazard identification in power engineering construction site should include: routine and unconventional activities; Activities of all personnel in the operation site; All facilities and devices in the operation field.
The safety, health and environmental management department of an enterprise shall, in conjunction with relevant departments, make a comparative analysis of all hazards that may cause casualties, equipment damage, environmental pollution and waste of resources on the construction site according to occupational safety, health and environmental laws and regulations and relevant regulations and standards, identify and confirm their hazards according to the Hazard Survey Form and the Environmental Factors Investigation Form, and compile the Hazard List and the Environmental Factors List. In the implementation process, according to the operation node, the list of dangerous sources and countermeasures are released irregularly.
(3) Formulation of technical measures for safety management in electric power engineering construction
Technical measures for construction safety are an important part of construction organization design, which is a safety management and technical file that specifically arranges and guides the safe construction of the project, and predicts the possible hidden dangers of accidents and possible safety problems in the construction process of each project. So as to take technical and management measures to eliminate or control unsafe factors in the construction process and prevent accidents. Strengthen the research on the feasibility and effectiveness of technical measures for construction safety, work out a feasible construction scheme, and strictly standardize the formulation, audit, approval, layout, disclosure, implementation and supervision of measures for engineering projects, so as to make the operation layer easy to perform and reduce the randomness in the construction process. Technical measures for construction safety shall be prepared, audited, approved and executed at the same time. For special engineering projects, individual construction safety technical measures must be worked out. In principle, "whoever organizes the construction shall compile the technical measures for construction safety", but when it comes to the professional cooperation type of work, individual technical measures for construction safety shall be proposed by the professional cooperation type of work.
the personnel who prepare the technical measures for construction safety must be familiar with the prepared construction project, go deep into the construction site to grasp the actual situation, conduct systematic analysis and evaluation, and find out the hazards and dangerous points, so as to make the determined technical measures for construction safety targeted, specific and clear, and ensure safe construction. After the technical measures for construction safety are compiled, they will be audited by the full-time engineer of the type of work, sent to the first-level joint review, and then approved by the chief engineer of the project department. If problems are found in the implementation process, the implementation should be stopped, and the modification should be approved according to the original examination and approval procedures.
(4) Monitoring in the process of power engineering construction
With the technical scheme of construction safety, the key is to implement it. Before the operation, the technicians shall organize all staff to make safety technical disclosure and talk about it.
