What are the key points and control measures for dust control at construction sites?

1. Control points 1.1 Whether the project department’s dust control management system is sound and implemented, the key lies in implementation.

1.2 Whether the funds for dust control are implemented, whether they are earmarked, and whether they are allocated and used in a timely manner.

1.3 Whether the construction waste cleared from the construction site is cleared and stacked in accordance with the specifications.

1.4 When moving earthwork in and out of the construction site, whether the troughs and wheels of the vehicles are washed clean, and whether they are properly covered and cleaned.

1.5 Whether dust-proof measures such as fences and coverings are taken for dust-producing materials such as cement, dust, sand and gravel piled at the construction site.

1.6 Whether equipment that easily generates dust, such as woodworking machinery on the construction site, is placed in a relatively closed operating shed, and whether the wood chips, waste, etc. generated are cleaned up in time.

1.7 When cleaning the construction site, are there any watering or other dust prevention and vacuuming measures?

2. Control measures 2.1 This project establishes an environmental protection responsibility system with the project manager as the first responsible person, and establishes and improves it with the participation of all subcontractors and labor teams of the builder, supervisor, and construction unit. Dust control leading group and management network (specific list and network are attached).

2.2 The construction unit shall implement the funds for dust control, and the construction unit shall ensure that the funds for dust control shall be earmarked exclusively (the funds shall be managed by comrades).

2.3 This construction organization design plan will be reviewed and signed by the relevant functional departments of the project department. After the project department stamps and confirms it, it will be approved and signed by the company’s chief engineer and functional department heads. After stamping and confirmation, it will be reported to the supervisor. Filing.

2.4 Establish a dust control responsibility system and system, and prepare dust control accounts for phased operations.

2.5 The dust control measures and commitments of the project department shall be publicized in conspicuous places around the construction site.

2.6 Designate comrades to be responsible for the management of dust control at the construction site, and establish dust control files, work summaries, implementation plans, meeting minutes, publicity materials, etc.

2.7 Educate and publicize the knowledge and importance of environmental protection, dust control and other relevant aspects to all personnel participating in the construction operations of this project.

2.8 Decompose and implement the responsibilities of dust control work, namely: project manager → on-site construction person in charge → on-site dust person in charge → length of each construction operation → each professional subcontracting team, labor subcontracting team, The person in charge of the work team → the worker ensures that the dust control system at the construction site is implemented at all levels and controlled in place.

2.9 According to relevant regulations, the height of the fence around the construction site shall not be less than 3 meters. It shall be built with red bricks, painted with cement mortar, and then painted with white paint. Use red letters to write environmental protection and other promotional slogans.

2.10 Temporary fencing facilities shall be no less than 2 meters and shall be made of color steel plates firmly.

2.11 The working surfaces facing the street and residential areas are fully enclosed with green dense mesh safety nets.

2.12 The main roads at the construction site should be paved with reinforced concrete pavement with a thickness of not less than 20cm. The ground in the site should be hardened. Areas that are not hardened due to construction reasons should be covered with melon seed sheets or green netting to prevent the soil from being exposed. .

2.13 Cement and other dust-producing materials stacked at the construction site must be managed in a closed manner and exposed storage is not allowed. Lime, sand and gravel must be reliably enclosed and covered with green dense mesh at any time.

2.14 If construction waste and engineering slag cannot be removed from the site within 24 hours, a temporary storage yard will be set up, and dust prevention measures such as fencing, covering, and insulation will be implemented around the storage yard.

2.15 Bulk materials and construction waste above 6m3 must be transported in a closed manner. Construction waste and engineering slag cleared from the construction site must be bagged or transported in a closed manner.

2.16 If there is any vacant land that has been idle for more than three months on the construction site, the exposed ground should be temporarily greened or covered with green netting.

2.17 Before the transport vehicle leaves the construction site, the tank and wheels of the vehicle must be washed clean with high-pressure water gun equipment, and dust prevention measures such as fencing and covering must be taken. It is strictly prohibited to use compressed air to clean dirt from vehicles and the ground.

2.18 Construction sewage and mud at the construction site must be discharged after settling in the third-level sedimentation tank, and a dedicated person shall be responsible for regular cleaning.

2.19 When cleaning up construction waste or waste on floors, scaffolding, high-rise platforms, equipment and other materials, use water spraying and vacuuming measures. It is prohibited to use bamboo fences, board shovels, or air compressors. Dust blowing and other methods that generate dust are strictly prohibited. When cleaning garbage on the floor, it is strictly prohibited to directly dump the garbage on the ground and scatter it at high altitude.

2.20 Commercial concrete, commercial mortar and dry mortar will all be used in this project. For small amounts of concrete and mortar less than 30m3, you can mix them yourself, but practical dust prevention measures must be taken.

2.21 Within 30 days after the completion of the project, the construction site and surrounding areas shall be leveled, soil and piles removed, and the exposed ground shall be temporarily greened or covered with green netting.

2.22 From the start of this project to the completion of the project, the construction operations involving dust in this project must take measures to prevent and control dust in accordance with the requirements of this plan.

2.23 Teams, teams and individuals who violate the dust control measures in this plan will be punished in accordance with the relevant regulations of the company and the project department. Those responsible for causing adverse impacts will be punished in accordance with relevant laws, regulations and the company's regulations. Otherwise, they will be expelled from the construction site of this project and shall not be re-employed.
