Work accidents are things that must be avoided, so that's not inflicted loss on the company and workers. However, several workers still pay attention to occupational health safety regulations in work area found potential hazards. The research is conducted at PT Pindo Deli Pulp Paper Mills Indonesia Karawang Regency focuses preventive corrective maintenance activities prevent paper machine break...

The paper deals with the development of a simulator for approaching human errors in complex operational frameworks (e.g., plant commissioning). The aim is to integrate the quantification capabilities of the so-called ‘first-generation’ human reliability assessment (HRA) methods with a cognitive evaluation of the operator. The simulator allows analysing both error prevention and error recovery. ...

The Pulverize is a major part of the boiler combustion system and an important part in the system of steam power plant (PLTU). Pulverizer plant serves to break chunks of coal into the coal ash was then fed to the burner. Type of feed coal into a pulverize is cleaned with a value product pulverize optimum 30%. The percentage of this value greatly affects the production of steam in the boiler. Th...

The size and complexity of industrial chemical plants, together with the nature of the products handled, means that an analysis and control of the risks involved is required. This paper presents a methodology for risk analysis in chemical and allied industries that is based on a combination of HAZard and OPerability analysis (HAZOP) and a quantitative analysis of the most relevant risks through...

Safety analysis (SA) procedures, such as Hazard and Operability analysis (HazOp) and Failure Mode and Effect Analysis (FMEA) are generally regarded as repetitious, time consuming, costly, and require a lot of human involvement. Previous efforts have targeted automated support for SA at the design stage of system development. However, studies have shown that the cost of correcting a safety error...

BACKGROUND The aim of this study was to identify the hazards, evaluate their risk factors and determine the measure for promotion of the process and reduction of accidents in the chemical unit of the power station. METHODS In this case and qualitative study, HAZOP technique was used to recognize the hazards and problems of operations on the chemical section at power station. Totally, 126 devi...

The safety and environmental aspects of a manufacturing process are important due to increased environmental regulations and life quality. In this paper, the concentration of aerosols in the breathing zone of the operator of Electrical Discharge Machining (EDM), a commonly used non traditional manufacturing process is presented. The pattern of aerosol emissions from this process with varying pr...

Risiko kecelakaan kerja pada proyek konstruksi merupakan risiko yang tinggi, namun terkadang faktor-faktor dapat mengurangi masih kurang mendapatkan perhatian. Menurut Peraturan Menteri Pekerjaan Umum Nomor : 05/PRT/M/2014 Bab 1 Pasal Sitem Manajemen Keselamatan dan Kesehatan Kerja Konstruksi adalah bagian dari sistem manajemen organisasi pelaksanaan pekerjaan dalam rangka pengendalian K3. Pene...

A prototype prediction based intelligent diagnostic system that is capable of integrating qualitative and quantitative process models and operation experience in the form of HAZOP result tables is proposed in this paper. The knowledge base of the system is organized in a hierarchical way following the hierarchy levels of the multi-scale model of the process system. This supports the focusing of...
