39 control items for construction sites
Thread Content
The main measure we take is the accident-prone area control method. It involves categorizing all individual construction tasks, identifying the accident hazards that are most likely to occur in each type of work, taking preventive measures, and creating daily inspection sheets. The on-site safety officer is responsible for recording these inspections on a daily basis; any potential accident hazards identified must be reported promptly to the project supervisor, who will then take action to eliminate those hazards, thereby achieving the goal of preventing accidents. Through years of exploration and summarization, and in conjunction with standard compliance, we identified 39 subsystems within construction activities, which contain a total of 362 accident-prone points to be addressed on-site. By doing this, we have solved three problems: first, the safety inspections are highly targeted; second, on-site safety officers, regardless of their education level or experience, can carry out the tasks using the provided checklist; third, it is simple and easy to implement, requires little cost, and is easy to spread across different locations. The 39 subsystems where accidents are likely to occur are as follows: 1. Basic construction site systems, which can lead to various types of safety accidents and occupational hazards – 13 cases; 2. Trench excavation, which can result in soil collapse and mechanical injuries – 7 cases; 3. Manual hole-digging for piles, which can cause collapse-related injuries and blasting-related injuries – 8 cases; 4. Earthwork and stonework operations, which can lead to collapse-related injuries and blasting-related injuries – 8 cases; 5. Management of explosives, which can result in explosions and fires – 13 cases; 6. Use of electricity in construction, which can cause electric shocks and damage to electrical equipment – 10 cases; 7. Operation of mechanical equipment, which can lead to mechanical injury accidents – 32 cases; 8. Road transport, which can cause traffic accidents and vehicle overturns – 11 cases; 9. Scaffolding work, which can result in scaffolding collapse, falls from heights, and object strikes – 9 cases; 10. High-rise building construction, which can lead to scaffolding collapse, falls from heights, and object strikes – 6 cases. Last edited by Desert Poplar on 2009-2-5 15:28
