(6) Electrical safety and safety in multi-tower operations.

10) Construction machinery:

(1) Installation and acceptance procedures;

(2) Safety protection devices of machinery;

(3) Electrical safety, protect the neutral line connection and use of leakage protector.

11) Lifting and hoisting:

(1) Construction plan and approval procedures;

(2) Safety status of lifting machinery and safety of lifting operations Key points;

(3) Operator certification status;

(4) Protection for lifting operations at high altitudes.

12) High-altitude operation projects: including edge operations, hole operations and independent suspended operations.

(1) The main protection for edge operations is to set up protective railings. The railings should be composed of upper and lower horizontal bars and railing posts. The height of the crossbar from the ground is 1.0-1.2M for the upper bar and 0.5-0.6M for the lower bar. The railing pole should be able to withstand an external force of 1KN from any direction. Safety doors should be installed.

(2) When operating at the entrance, solid covers, protective railings, dense safety nets or other anti-fall facilities must be installed depending on the specific circumstances.

(3) At the construction site, when working in the open air with a height of 2M and above, firm footholds such as operating platforms, scaffolding or hanging baskets must be set up before construction can begin.

(4) When up and down operations are performed simultaneously in the same vertical direction to form cross operations, a safety protection layer must be installed in the middle.

(5) Safety helmets, full belts and safety nets should be used correctly.

13) Civilized construction:

(1) On-site fencing: the height, stability, cleanliness and beauty of the fencing;

(2) Closed management: gate and door signs and doorman management;

(3) Construction site: roads are hardened, smooth, and have drainage measures;

(4) Material stacking: stacked neatly according to the plan and marked with classification ;

(5) On-site accommodation: separate from the operation area, and the dormitory meets sanitary requirements;

(6) On-site fire prevention: there are systems, measures, and facilities;

(7) On-site signage: There are standardized and neat signboards, safety slogans, publicity boards, etc.;

(8) Living facilities: There are canteens, toilets, bathrooms and other facilities, and they meet health requirements;

p>

(9) Health first aid: There is a clinic or health box, and there are first aid health care measures;

(10) Community services: There are people-friendly and convenient measures, and comprehensive public security management.

14) Fire prevention: The construction unit shall establish a fire safety responsibility system at the construction site, determine the person responsible for fire safety, and formulate various fire safety management systems for fire, electricity, and the use of flammable and explosive materials. Operating procedures, set up fire exits, fire water pumps, equipped with fire fighting facilities and fire extinguishing equipment, and set up obvious signs at the entrance to the construction site.

2. Supervision and handling of hidden dangers (accidents) in engineering safety production

1) If during the supervision and inspection it is found that the responsible parties of the project construction have violated the safety production regulations, our station will Issue a "Project Rectification Notice". If the safety production assurance system at the construction site is imperfect, there are many hidden dangers, and supervision and inspection problems are not rectified effectively, or if the safety production behavior of all parties participating in the construction seriously violates laws and regulations, and if the conditions for partial suspension of construction are met and the construction needs to be suspended, the construction shall be suspended in accordance with the regulations. Requirements and procedures, issue a "Notice of Partial Suspension (Suspension) of the Project", etc., and order corrections. For projects that have been partially suspended (suspended), before resuming work, the responsible unit should fill in the "Rectification Completion Report". If the review meets the requirements, the quality supervision station will issue a "Resumption Notice". Our station will record, regularly summarize, and disclose to the public any bad behaviors discovered by responsible entities and relevant institutions during supervision and inspection. If the safety production behavior of each responsible entity constitutes a violation of laws or regulations and requires administrative penalties, it shall be reported to the superior construction administrative department for administrative penalties.

2) Disclosure and tracking rectification system for major construction safety hazards.

Major hazard sources at the construction site include: major hazard sources at the construction site and major hazard sources in the areas surrounding the construction site. During the supervision process, a general survey and registration of major hazard sources in construction projects will be carried out to understand the number and distribution of major hazard sources, and the list of major hazard sources in construction projects, rectification measures and management status will be regularly announced to the public.

3) Interview system for major construction project safety accidents (accident hazards).

For projects where serious accidents occur, or projects where the safety production guarantee system at the construction site is imperfect, there are many hidden dangers of major accidents, and supervision and inspection problems are not rectified effectively, or the safety of the parties participating in the construction is responsible For projects with serious illegal or illegal production activities, the site manager of our station will interview and admonish the responsible persons of the construction units and other relevant responsible entities of the above-mentioned projects, and the records of the interviews and admonitions will be made public to the public and reported to the superior construction administration. competent authority.

4) If serious injuries, deaths, mechanical equipment and other major accidents occur during the construction process, they should be reported to our station and the relevant competent authorities within the specified time, and the site should be protected. Late reports, concealed reports, Those who damage the accident scene will be punished according to relevant regulations.
