What are the fire protection requirements (electric welding, construction electricity, etc. ) on the construction site?

1. All units shall comply with the fire safety requirements in the general construction plan, construction method and construction technology when preparing the construction organization design.

2. The construction site should be clearly divided into hot work, flammable and combustible materials yard, warehouse, flammable waste centralized station, living quarters and other areas.

3. The night construction site should have lighting equipment; Keep the passage of fire engines unblocked and arrange forces to strengthen patrol on duty.

4. Temporary buildings that need to be built during the construction operation must be approved by the technical director of the construction enterprise, and should be dismantled in time after the construction. However, temporary buildings or combustible materials shall not be erected under high-voltage overhead.

5. The construction site should be equipped with enough fire-fighting equipment, and designated personnel to maintain, manage and update regularly to ensure that it is complete and easy to use.

6. During civil construction, fire-fighting equipment and facilities should be provided first, and outdoor fire hoses and fire hydrants should be laid when conditions permit.

7. The distance between the welding and cutting operation point and dangerous goods such as oxygen cylinders, calcium carbide barrels and acetylene generators shall not be less than 10m, and the distance between the welding and cutting operation point and inflammable and explosive articles shall not be less than 30m；; If the above requirements cannot be met, the hot work approval system should be implemented and effective safety isolation measures should be taken.

8. The distance between acetylene generator and oxygen cylinder storage shall not be less than 2m; When in use, the distance between them shall not be less than 5m. 9. Safety accessories on welding and cutting equipment such as oxygen cylinders and acetylene generators should be complete and effective, otherwise they are not allowed to be used.

10. The welding and cutting on the construction site must meet the requirements of fire prevention, and the "ten no-burning" regulations shall be strictly implemented:

1) Welders must hold relevant certificates, and welding and cutting operations are not allowed without the safety operation certificate of special operators in Shanghai;

2) All welding and cutting operations within the scope of Grade I, II and III hot work shall not be carried out without going through the hot work examination and approval procedures;

3) The welder shall not carry out welding and cutting without knowing the surrounding conditions of the welding and cutting site;

4) When the welder does not know whether the inside of the weldment is safe, welding and cutting are not allowed;

5) All containers containing flammable gases, flammable liquids and toxic substances are not allowed to be welded or cut without thorough cleaning and hazard elimination;

6) Where combustible materials are used as insulation layer, cooling layer and sound insulation equipment, or where sparks can splash, welding and cutting are not allowed before practical and reliable safety measures are taken;

7) Pressure or closed pipes and containers are not allowed to be welded or cut;

8) There are inflammable and explosive articles near the welding and cutting parts. Welding and cutting shall not be carried out before cleaning or taking effective safety measures;

9) When there is a type of work that conflicts with open flame operation nearby, welding and cutting are not allowed;

10) It is not allowed to weld or cut the parts connected with other units without knowing whether there is danger or knowing that there is danger without taking effective measures.

1 1. When using electricity on the construction site, the regulations of the Municipal Construction Committee on the safety management of electricity consumption on the construction site should be strictly implemented, and the management of electricity consumption should be strengthened to prevent electrical fires.

12. When heat preservation and heating measures are adopted in winter construction, the following requirements shall be met:

1) adopts electric heating mode, and the voltage regulator should be set to control the voltage; The wires shall be well insulated and firmly connected, and several measuring points shall be set on site.

2) When using sawn quicklime for heat storage, a safe mixture ratio should be selected, and it can only be used with the consent of engineers and technicians.

3) Before taking heat preservation or heating measures, safety education should be conducted; Arrange special personnel to patrol and inspect during construction, and handle hidden dangers in time.
