Safety production management system

The safety work leading group of our unit leads the overall safety work, and its main responsibilities are to lead our unit to carry out safety education, carry out and publicize all kinds of laws and regulations, notices and the spirit of the documents of the higher authorities, formulate all kinds of management regulations, and conduct safety work inspection and appraisal on all projects every month. The project department shall set up a safety management team and a full-time safety officer, whose main duties are to be responsible for the safety technical disclosure of workers, implement the spirit of superiors, check the safety work of engineering construction every day and hold an engineering safety meeting once a week. Formulate specific safety regulations and illegal treatment measures, and report to the safety leading group of our unit once. Each operation team shall set up part-time safety officers, mainly to lead each team to operate carefully, give patient guidance to each worker, deal with potential safety problems immediately when they are found, and report their work to the site safety management team in time.

3. Safety inspection system

In the construction process, in addition to the normal safety inspection, my unit checks once a month, my unit checks once every half month, and the project department checks once a week. When problems are found, they are implemented to people, and rectification is carried out within a time limit to eliminate hidden dangers and ensure construction safety.

4. Safety education system

According to the safety education system of our unit, we will strengthen publicity and education, formulate a scientific and reasonable construction plan, organize practical operation procedures on site, and correctly and strictly implement and apply construction and safety specifications. Conduct a diagnostic test for the workers entering the site, conduct unified safety education, and enhance the awareness of quality and safety. Seriously study and deeply understand the construction technical specifications and construction safety specifications. Only employees who have passed the training and disclosure are allowed to operate at their posts, laying a solid foundation for the smooth and successful development of safety work. In the process of construction, establish weekly safety education, presided over by full-time security officer. At the same time, before each construction process, the full-time safety officer will make a written safety technical disclosure, and each team leader will lead the construction personnel to seriously implement it. In the general layout design of construction, the planning of the safe passage for people and goods flow, the layout of warehouses, materials and machines should comply with the regulations on fire control, safety and hygiene, and the first-aid facilities for fire control and hygiene should be implemented, and different types of safety protection sheds should be set up. Before the structure construction, special safety technical schemes are specially prepared for each construction system. During the vertical transportation of materials in construction, special safety management regulations should be formulated.

5. Safety of construction machinery

Use it according to the operating procedures, strengthen the management of mechanical equipment, and make regular inspections, repairs and maintenance to keep it in good working condition. 6. Measures to prevent strong wind, rain and lightning:

Derrick and outer frame must have lightning protection measures. Lightning protection grounding can be connected with the lightning protection embedded parts of the project by temporary welding, and the grounding resistance meets the specified requirements. It is tested once a month, and the problems are corrected in time when found. Master meteorological information, make timely forecast of strong wind and heavy rain, and take corresponding technical measures to prevent accidents. It is forbidden to construct under severe climatic conditions such as strong wind and heavy rain.

7 The floor-type double-row steel pipe scaffold and climbing frame are used for safety protection and external wall construction of this project, and the outer side adopts fully closed dense mesh safety hanging net. See also the scaffold construction scheme.

8. Safety signs and safety protection
