Abstract. The North-South Expressway (NSE) (Lebuhraya Utara-Selatan) is the longest expressway in Malaysia with the total length of about 772 km (482 miles) running from Bukit Kayu Hitam in to Johor Bahru. It is known named after the highway's concessionaire, Projek Lebuhraya Utara Selatan Berhad (North South Expressway Project) abbreviated as PLUS Expressway. A study on the occupational safety among maintenance workers of PLUS Expressway was conducted. The aim for this research is to identify the hazards and determine the risk level of highway maintenance works. This research has identified the hazards occupies during highway maintenance works. Subsequently, the levels of risk for hazards during highway maintenance works are determined. The scope of this study is along the northern PLUS Expressway specified from Southern Ipoh to Bukit Kayu Hitam and focused on the maintenance workers of Projek Penyelenggaraan Lebuhraya Berhad (PROPEL). Eighty (80) sets of questionnaires survey on likelihood and severity of highway maintenance hazards have been distributed to highway maintenance workers. The data were analysed by using Excel to compose weightage average index (WAI) in order to compute the risk level of those hazards. The result concluded that the extreme level of hazard that occurred during maintenance of highway are hazards related to electricity, hazards that engage with scaffolding, hazards while using crane and hazards involve fire and explosion.

Abstract. The function of minimization of construction solid waste is to reduce or eliminates the adverse impacts on the environment and to human health. Due to the increase of population that leads to rapid development, there are possibilities of construction solid waste to be increased shortly from the construction works, demolition or renovation works. Materials such as wood, concrete, paint, brick, roofing, tiles, plastic and any other materials would contribute problem involving construction solid waste. Therefore, the proper waste minimization is needed to control the quantity of construction solid waste produced. This paper identifies the type of construction solid waste produced and discusses the waste minimization practice by the contractors at construction sites in Selangor, Kuala Lumpur and Putrajaya, Malaysia.

Operation of Pakistan Research Reactors 1 and 2, radioisotope production plants, and allied laboratories at the Pakistan Institute of Nuclear Science & Technology (PINSTECH) generates radioactive waste effluents of low and intermediate level. These waste materials are managed in a way to keep the human health and the environment free of radiation associated hazards. The prime practice has been of shallow ground or near-surface disposal type. Different measures and operational procedures at the institute, in step with the international norms for the management of low and intermediate level waste, have been adopted. To ensure the safe disposal practices and radiation safety of the workers and of the general public, radiological safety related routines are practiced with due concern. Some safety aspects of the prevailing practices are discussed in this presentation.

Abstract. The development of Malaysia's economy gives the opportunities for companies to explore and operate overseas. A company has to ensure that the selected individuals are willing to work abroad, have high perseverance and always ready to meet challenges. The success of implementing the overseas assignment does not solely depend on technical expertise. It also depends on non-technical issues such as the ability to interact with colleagues at work, adaptability to the new environment and openness to the local culture. Past studies found 65% of the companies indicated that 5% of their expatriates returned prematurely from their assignment. This research, however, proved that non-technical factor such as work adjustment ought to be considered by the company. One of the non-technical factors that contribute to the failure is the expatriate's inability to adapt to the new environment. This paper will also look into the factors that are faced by the expatriates during expatriation. The findings are obtained from empirical study and 64 respondents from Malaysian expatriate executives overseas. Suggestions and recommendations are given to improve the work adjustment of the expatriates.

This study focuses on the piling works of Mass Rapid Transit (MRT) line 1 construction project along Sungai Buloh Station to Kajang Station in Malaysia, considering that piling work is one of the high risk construction activities. This study utilizes risk assessment tool using Hazard Identification, Risk Assessment & Risk Control (HIRARC) to create safe construction workplace. The hazard identification is a process of examination work area and task inherent to piling activities. The risk assessment of piling works calculated using likelihood and severity. Based on the hazard identification and risk assessment results, control measures or risk control are taken into action. The risk assessment sheets as the research instrument tool were filled by 30 construction professionals and safety practitioners i.e. safety officers, safety supervisors, site engineers and site supervisors. The results indicated that there were seven hazards that associated with piling works. One of the hazards which caused structure collapse during test pile activity was assessed as the extreme risk. Other six hazards were assessed as high risk. The total 27 risk control measures were resolved in order to eliminate and reduce hazards as well as prevent accident during piling work at the MRT construction project.
