Safety Measures for Fire Prevention, Explosion Protection and Lightning Protection in Construction Sites

1. Do not privately use electric stoves, rice cookers, electric cups, kerosene stoves, etc. in the dorms, and do not allow unauthorized use of electric lights. Do not use light bulbs of more than 60 watts in the dormitory .

2. Strengthen the management, maintenance, and maintenance of fire-fighting equipment, and always keep it fully functional. A suitable number of fire extinguishers during the service period should be equipped on the side of the woodwork shed.

3. In the construction organization design, firefighting passages should be planned to ensure unimpeded access of fire engines.

4. For high-rise building construction, floor operations and ground command agencies must have reliable communication equipment. Once there is a dangerous situation, the operation site can report to the commanding department in time.

5. Scaffolding with combustible materials should not be used for high-rise building construction. Regardless of the construction and decoration of the structure, it is necessary to clean up the excess flammable materials in time and transport it out of the site to a reliable place.

6. The distance between welding and cutting work points and dangerous goods such as oxygen cylinders and acetylene generators shall not be less than 10 meters , and the distance from flammable articles shall not be less than 30 meters . If the above requirements are not met , special isolation equipment shall be provided. After special approval.

7. The on-site welding and cutting personnel shall carry out special fire prevention education. The construction site shall establish safety requirements for welding and cutting operations in accordance with the project conditions.

8. As far as possible, high-rise buildings do not use open flame to melt the asphalt, for example, they must melt the asphalt. It must not be carried out in the building or with open flames.

9. In the stage of decoration construction, paints, etc., have the emission of flammable gas. In addition to paying attention to timely ventilation, fire safety measures shall be formulated.

10, there are two distribution network must have at least the fire valve can be used directly for fire water site.

11. Fire-fighting high-pressure water pumps have special wires.

12. Put a set of fire extinguishers on each floor and at each stairway.

13 , in the external wall welding, special personnel should guard and check the following fire conditions.

14. The person in charge of construction site power management at the site shall be responsible for the issuance of electricity licenses for all kinds of electrical equipment. The electrical workers entering the construction site shall be provided with electrical operation and shall be responsible for checking the electricity safety of the site.

15. Electrical workers strictly abide by the low-voltage electricity regulations.

16 , must implement the shift record system.

17. The cable at the site must be buried and threaded (marked on the ground) or overhead on the utility pole. It must not be installed on a steel pipe scaffold.

Lightning protection measures

1. The metal housing of all electrical equipment and the metal structure connected to the electrical installation must have reliable zero or ground protection. When borrowing power, you should first understand what kind of protection the electrical equipment in the borrowed power system uses before you can determine whether ground or zero protection is used.

2. It is recommended to use multi-strand copper wire for the protection of zero line, and it is forbidden to use single strand aluminum wire. The single-phase zero line has the same cross section. For the three-wire and four-wire system, the zero line of protection shall be no less than 1/2 of the phase section (except for the use of cables), and the zero line of hand protection shall be allocated to the control line.

3. The working zero line and the protection zero line should be separated. They must not be combined into a single line. The zero line should not be connected in series. There must be no joint in the middle of the protection neutral line of the welding machine and running lamp transformer, and the use of bolts and other conductors is not allowed.

4. The connection between the neutral line and the equipment and terminal board must be firm, and no dummy connection is required . The full 3600 ring is required . When there is no official pressure wire nose, be sure to wrap the tight end and padded it. The pressure point should be set in the light, and each screw of the terminal board can only protect the neutral line of one device.

5. Single-phase 220V electrical equipment with zero-protection shall be provided with a separate protection neutral line, and shall not use the equipment's own working zero line and zero line protection.

6. Lightning protection measures shall be taken for derricks, tall shelves, machine tools, water towers, and chimneys with a height of 20 meters or more. After the formwork is in place in the large formwork construction, it shall be connected to the building grounding wire in time with wires. Its grounding resistance should be less than 10 Ω.
