Analyzing actual hazard indications in the field
Risk factors are analyzed by analyzing the scaffolding installation work and the state in which the safety hook is not fastened when moving on the scaffold. In particular, it was analyzed that the risk of an accident was greatest when workers who did not fasten the safety hooks without the work scaffolding installed.
KOSHA Safety Accident Report Analysis
It is analyzed that such an accident could have been prevented if the work had been carried out after checking the loosening of the scaffold connection or connection, installing safety belt attachment facilities, and wearing safety hooks before dismantling the scaffold.
Analysis of Visual Intelligence Technology Applications
Development of image recognition target derivation process
Regulatory analysis for deriving image recognition targets
Among the safety and health rules established by KOSHA, related laws and regulations are analyzed by selecting the installation and dismantling of scaffolding and the conclusion of safety hooks when working on scaffolding. The contents of the analyzed laws and standards are regulated so that they can be observed under the leadership of the employer.
Analyzing image recognition elements
By analyzing the elements that need to be recognized in the image in order to recognize the image, and by analyzing the image recognition elements according to the process using the information obtained through legal review, the process can be used to establish the order of objects to be recognized in the image for safety hook engagement.
Image recognition applied to the case site
1. Job definition
- System Scaffolding Installation Task
- Working on system scaffolding and unloading scaffolding
2. Compliance with laws and Compliance
- Is the working platform properly installed before work?
- Does the safety belt attachment facility be installed?
- Did the worker wear a safety belt and hang it on the attachment facility?
3. Image Recognition Element Analysis by Process
- Recognition of exterior walls (installation)/scaffolding (work on scaffolding and dismantling)
- Check if the work platform is installed
- Check if the safety belt attachment equipment is installed
- Wear safety belt and check safety hook connection
4. Derive image recognition targets
- Exterior wall (installation)/scaffolding (work and dismantling on scaffolding)
- Working platform
- Attachment of safety belt
- Safety band
- Safety ring
