Abstract: A large vessel, such as a container ship or an oil tanker, requires painting processes that include not only application, but also cleaning, substrate preparation and corrosion treatment. Moreover, these processes take place during construction (both in the construction of blocks in the workshop and in the assembly at the dock) and also during the operation phase of its life cycle, as part of its maintenance. This research analyzes the advantages of the implementation of key enabling technologies in painting processes versus the proposal of preventive measures, collective and individual protection, and training of workers in traditional manual processes. Using the Fine-Kinney method, which assesses potential hazards and associated risks, the degree of danger of the different tasks present in the current painting processes of large vessels is measured. These risk scores is compared with those of the new activities resulting from the simulation and automation of the associated processes, analyzing their justification by confronting their level of correctness (risk mitigation) with the cost factors of their implementation. The results show that, from a health and safety point of view, the proposal of these measures is fully justified. Therefore, it can be concluded that the inclusion of key enabling technologies in the painting processes of a ship throughout its life cycle drastically reduces risk levels, improving the safety and health conditions of the workers involved, without prejudice to an increase in the cost of services or in the delivery deadlines to the client, which confirms their reliability.

Abstract: This article is devoted to the description of methods for improving the efficiency and production of autoclaved materials and lime, as well as an increase in safety in their production. The basis of the proposed technical and technological methods is a new method for the production of autoclaved materials. As part of the scientific work on improving the quality of autoclaved products, an additive (copper sulphate) was found, which makes it possible to slow down the lime hydration time in the binder for several hours, which makes it possible to apply the mechanical activation of lime-silica binder with wet grinding and improve working conditions in the workplace.

Using LEC method to mine in the workplaces where harm worker healthy environments were evaluated and harm through improved LEC method for scientific management, and put forward effective countermeasures to control, for the prevention of occupational health hazards in mines and puts forward scientific basis for control.

Abstract: The work of occupational health and safety about construction industry has increasingly aroused peoples' attention ,so this article puts forward the problems existing in the occupational health and safety management of construction industry as well as the countermeasures and suggestions through the analysis of the construction labours' common occupational injury accident of the present stage in our country and the status quo in the aspects of professional physical,mental health and safety ,which is to develop the workers' way of life on safety,civilization and health.

Abstract: The performance of a commercially available Local Exhaust Ventilation (LEV) system for controlling mist, vapor and fume exposures during two-piece slim retractable aluminium can production line was assessed. This study focused on monitoring of LEV system performance in different phases of production which are drawing and wall ironing. Data such as static pressure, velocity pressure, transport velocity and flow rate values was obtained as a specific requirement to analyze the performance of the system. The first LEV system used to control mist exposure from drawing activities and the second system was implemented to control fume and vapor during ironing wall process. The performance of the system was investigated and compared with standard as required by USECHH Regulation 2000. The results of LEV system monitoring were discussed and several recommendations were proposed to improve the performance of the system and to reduce the mist, fume and vapor exposure for occupational safety and health purposes.

Abstract: This paper identifies the trends in existing literatures on management system standards such as Quality (Q), Environmental (E), Occupational Health and Safety (OHS), and Energy (En) Management System (MS). Literatures related to these management system standards (MSSs) and its integrations published between year 1980 to 2012 have been critically analyzed. It provides a general overview of the Integrated Management System (IMS) implementation and the composition of MSSs in developing IMS in various organizations. Based on the analysis, it is firm that the integration of these four (4) MSSs has not been well established. Despite that, the recurring themes of the literatures related to IMS are mainly, model for implementation, strategies and guidelines for implementation, benefits of implementation, barriers/ problems of implementation, audit of IMS, Critical Success Factors for implementing IMS and IMS Audits.

Abstract: ndoor Air Quality (IAQ) has become an important occupational health and safety concern in educational environment at institutions of higher learning. In a survey conducted on a polytechnic in Malaysia, many of the students and lecturers expressed feeling of discomfort and uneasy due to resulting smoke from the welding activities while attending the workshop session. They felt that the room temperature and humidity also contributed to discomfort. Consequently, students had difficulties to concentrate and focus on their learning. The objective of this study was to determine the indoor air quality of a selected welding laboratory in the polytechnic comprising arc and gas welding stations. The important IAQ parameters considered in this study were the dry bulb air temperature, relative humidity, CO₂ level and dust particles. Measurements were conducted using commercial IAQ instruments. From the study it was found that the levels of dust particles was higher than the recommended limit at times in the arc welding station. The CO₂ level was observed acceptable in both welding stations. On relative humidity, a mixed result was found. Overall, the results implied that the welding laboratory require attention in meeting acceptable Indoor Air Quality.

Abstract: This paper discusses the strategies for integrating Quality, Environmental, Safety and Health Management Systems based on survey and case studies results. Questionnaires were distributed to 87 companies that certified with both ISO9001 and ISO14001. Meanwhile, three case studies were conducted at the manufacturing companies that have integrated several management systems. There are two ways of integrating the management systems which are: (1) consecutive implementation of management systems followed by integration or (2) integrate the management systems simultaneously from the beginning. Based on survey and case studies, it was found that many organisations started with implementing individual management system first, and then followed by integrating the management systems. Almost all the survey respondents agreed that the sequence should start with establishing Quality Management System first, and then integrate with Environmental Management System and followed by Occupational Health and Safety Management System.

Abstract: All organizations, regardless of their size or complexity are faced with the challenge of implementing an Occupational Health and Safety (OH&S) management system that will prevent injuries and ill health to persons that are working under the control of the organization. The purpose of this paper is to show how organizations can improve their health and safety performance through the effective implementation of existing statutory requirements and regulations. Using a case study from a Printing Industry organization, the key requirements needed to implement a H&S programme and focus on the concept of hazard identification, risk assessment and risk control were investigated. The organization is a large company, which has implemented a system to the requirements of the Occupational Health and Safety Act: 2005. Findings reveal that there is a lack of control procedures to ensure compliance to legal requirements. The Health and Safety Policy needs to be reviewed. Significant hazards need to be prioritized. The company does not regularly conduct risk assessments. Employees need more training on H&S issues. Use of hazardous substances must be properly controlled. Appropriate H&S objectives and targets have to be set and regularly monitored. Internal auditing, which has up to now been limited to their ISO 9000:2008 certification, should be extended to the OH&S Management systems. To enable a better control of the situation, it is recommended that OHSAS 18001:2007 should be implemented, including the concept of continual improvement, to assist in more effective control of the Occupational Health and Safety regulations.
