3. 2 organization of training in temporary electrical safety education for all categories of electrician personnel (including on-site managers, technicians and electricians, electrician operators, etc.) to be qualified for induction。
The electrician must be certified to take up his post after being certified in accordance with the national code for the management of the safety technology examination of special operators. The installation, inspection, maintenance or removal of electrical equipment and lines must be done by an electrician and supervised. Non-electricians are prohibited from working as electricians, and unqualified electricians are not allowed to work without a permit。
3. 3 the electrical distribution cabinets, boxes and identification plates for temporary use at the construction site shall be equipped with uniform standards. A 3c mandatory certification of electrical equipment, such as electrical distribution cabinets, boxes and wires, must be performed。
3. 4 the temporary electrical system or works shall be carried out strictly in accordance with the technical measures designed by the temporary electrical construction organization or the temporary electrical safety measures, which shall be tested, accepted and approved by the organizational unit of the project unit。
3. 5 prior to the use of electrical equipment, the electrician is required to wear the corresponding labour protective materials and to check the integrity of the equipment used and its associated switches, controllers and protection facilities, and only after confirmation that it has been completed, can the electrical power be connected to the gates and the equipment be banned from being operated and used with defects。
3. 6 in the course of the operation, the electrical equipment is operated in such a way that the person remains on guard and, in the event of an anomaly, the power supply must be severed immediately, shut down, and the electrician is required to inspect and process it。
3. 7 switches for the temporary decommissioning of the equipment shall be separated from the power-segregation switch and shall be closed and locked so as to allow people to pass out the power outages and to prevent the accidental misrouting of the equipment
3. 8 mobile electrical equipment shall be cut off and properly processed by an electrician, shall not be self-destructed, shall not be exposed to wires with or possibly with electrical power, and shall be prohibited from moving electrical equipment without reliable power cuts。
3. 9 specialized supervision shall be exercised in connection with electrical operations, such as at humid sites and in the vicinity of electrical installations; the level of knowledge of the safety and operation of the guardianship personnel shall not be inferior to that of the operator; and the guardian shall carry or use, in the exercise of his or her guardianship, basic safety devices and shall not perform any other work。
3. 10 maintenance of electrical equipment must be carried out by licensed electricians in strict compliance with operational protocols, and electrical maintenance is strictly prohibited。
3. 11 the electrician shall fill out the record of the electrician's installation, inspection, maintenance and demolition work in a timely manner, and shall provide a weekly signature from the team leader。
4. Temporary electrical security screening
4. 1 the project department and the shelf team shall be equipped with a ground resistance tester, an insulation resistance tester, and shall perform regular insulation, ground resistance detection and leak protection checks and fill in the corresponding records。
(a) insulation of electrical products
1) after entering the field of electrical products (including handheld, mobile electric tools) (pre-use) an inspection must be organized and insulated and recorded。
2) newly purchased, long unused and overhauled electrical products must be tested and documented before distribution。
3) after electrical maintenance and quarterly testing。
(b) in situ electrical resistance detection
