Description
본 발명은 작업 안전 관리 시스템에 관한 것으로, 더욱 상세하게는 웨어러블 장치와 단말기를 사용하여 작업전 안전 조치 절차를 수행하면 작업 허가서의 생성 작업 허가 절차가 자동적으로 수행되는 작업 안전 관리 시스템의 동작 방법에 관한 것이다. The present invention relates to a work safety management system, and more particularly, to a method for operating a work safety management system in which a work permit creation process is automatically performed when a safety measure procedure is performed before work using a wearable device and a terminal. it's about
산업안전보건기준에 관한 규칙에 따르면, 산소 결핍이나 유해 가스로 인한 질식, 화재 및 폭발 등에 의한 사고 위험이 있는 장소를 밀폐 공간이라고 정의하고 있다. 구체적으로 산소 농도가 18% 미만이거나 23.5% 이상인 경우, 탄산가스 농도가 1.5% 이상인 경우, 황화수소 농도가 10 ppm 이상인 밀폐 공간에서 작업자가 작업할 경우 질식 사고의 위험이 크다. 따라서, 질식 사고를 방지하기 위해 작업 환경에 안전 사고를 유발할 수 있는 유해 기체와 같은 환경 요인들을 감지하는 센서가 설치된다. According to the rules on occupational safety and health standards, an enclosed space is defined as a place where there is a risk of accident due to oxygen deficiency or suffocation due to harmful gas, fire, or explosion. Specifically, when the oxygen concentration is less than 18% or 23.5% or more, the carbon dioxide concentration is 1.5% or more, and the hydrogen sulfide concentration is 10 ppm or more, the risk of suffocation is high when workers work in confined spaces. Therefore, in order to prevent an accident of suffocation, a sensor for detecting environmental factors such as harmful gases that may cause a safety accident in the work environment is installed.
더불어, 최근에는 유해 가스에 직접 노출되는 작업자 주변의 유해 기체의 농도를 센싱하여 위험을 알려주는 웨어러블 디바이스가 보편화되고 있다. 웨어러블 디바이스를 스마트폰과 같은 단말기와 연동하여 운영할 수 있다. 유해 가스의 농도가 위험 수준에 도달하면, 작업자에게 알람을 통해 경고하고, 작업 관리 서버에도 전송하여 사고를 사전에 예방하는 효과를 제공할 수 있다. 특히, 질식 사고의 경우 근로자의 주변 환경을 실시간으로 감지하여 신속한 대처가 가능하다. In addition, recently, a wearable device that senses the concentration of harmful gases around a worker who is directly exposed to harmful gases and informs them of danger has become common. A wearable device can be operated in conjunction with a terminal such as a smartphone. When the concentration of the harmful gas reaches a dangerous level, an alarm is alerted to a worker and transmitted to a work management server to prevent accidents in advance. In particular, in the case of a suffocation accident, it is possible to quickly respond by detecting the surrounding environment of the worker in real time.
산업안전보건법 안전보건기준에 관한 규칙에 따르면, 밀폐 공간에서의 작업 전에는 밀폐공간안전보건작업 허가서의 작성과 부서장의 결재 및 승인이 있어야 작업의 시작이 가능하다. 밀폐 공간 작업이 이루어지는 현장에서는, 여전히 밀폐공간 작업허가서가 수기로 작성되고 책임자의 결재와 작업 허가된다. 그리고 작성 및 승인된 밀폐공간안전보건작업 허가서는 일정 기간 의무적으로 보관되어야 한다. 이러한 작업 절차는 밀폐공간안전보건작업 허가서의 작성 및 상신, 그리고 책임자의 결재 및 승인 과정은 복수 단계의 절차들과 서류의 전달 절차들이 동반된다. 따라서, 실무자 입장에서는 서류의 전달 절차나 승인 절차에서 상대적으로 많은 시간이 소요되는 문제가 있다. According to the rules on safety and health standards of the Occupational Safety and Health Act, before working in a confined space, a confined space safety and health work permit must be prepared and approved and approved by the head of the department to start work. In the field where confined space work is performed, a confined space work permit is still handwritten, and the person in charge approves and permits work. In addition, the written and approved confined space safety and health work permit must be kept for a certain period of time. These work procedures are accompanied by multi-step procedures and document delivery procedures such as drafting and reviewing confined space safety and health work permits, and approving and approving the person in charge. Therefore, from the point of view of practitioners, there is a problem in that a relatively large amount of time is required in the document delivery or approval process.
