    Exposure to organic solvent during work activities has been known to be associated with significant clinical conditions such as peripheral neuropathy and neurobehavioral changes. Three reported cases of peripheral neuropathy most likely due to exposure to chronic organic solvent were reported recently in Bentong Malaysia. These cases showed a compatible clinical history, occupational history, examination and neurological study that link with peripheral neuropathy due to organic solvent poisoning. Proper education and training with review of engineering control measures are among preventive and corrective measures recommended. More comprehensive study in order to establish significant causal-effect relationship as documented evidence is recommended.

    This paper presents the use of factorial experiments and response surface methodology to determine the best workstation design configuration of an existing electronic industry. The aim is to find the value of physical dimensions that gives the best performance for the workstation. Four performance measures are selected; the cycle time, the metabolic energy expenditure, worker’s posture during the task and lifting limitations. The methodology used in this study consists of two parts. The first part is based on factorial experiments and handles discrete search over combinations of factor-levels for improving the initial solution. In the second part, the solution that was obtained earlier is further refined by changing the continuous factors by using response surface methodology. The result of this optimization study shows that the optimum value of physical dimensions gives a significant improvement for the performance measures of the workstation.

    There are disturbing trends of emerging and re-emerging infectious diseases, globally and locally thus giving it a real cause of concern. These include diseases by agents hitherto unknown in human such as Severe Acute Respiratory Syndrome (SARS) and Ebola; those that were purely zoonoses but had now affected man such as bovine spongioform encephalitis (BSE) in United Kingdom and avian influenza in Vietnam and Thailand; those that were thought to be eliminated but reappeared such as plague in India and those that begun to show reverse trends such as tuberculosis (TB) and malaria. Malaysia is no exception. Viral fever EV71, Chinkugunya, Conjunctivitis C24 variant or Nipah encephalitis were local examples of unknown or exotic infectious diseases occurring in recent years. In this age of globalization with expanding air travel and industrial trade, Malaysia is vulnerable to a wide array of new and resurgent infectious diseases. Apart from the direct health consequences on morbidity, mortality and its staggering cost, these infections also have far reaching implications upon sustainable development, psychosocial, economic, political and global security.

    The objectives of this study is to evaluate subjective symptoms and neurobehavioral performances among workers exposed to lead and its relation with blood lead levels. The methodology of this study was restricted to 141 Malaysian battery manufacturing factories male workers with mean (SD) age of 35.2 (9.6) years, years of employment 9.1 (7.1), current blood lead concentration 40.5 (16.8) μg/dl were given WHO neurobehavioral core test battery. Results showed that highly exposed group blood lead level (high ≥ 40 μg/dl) performed less well in 4 of 13 responses reported higher subjective symptoms of weakness of lower limbs and anorexia. Significant correlation was found between blood lead and Digit Symbol, Digit Forward, Digit Backward, Aiming Pursuit Test and Trail B. Regression analysis showed reduction in cognitive, memory and concentration functions at ≤ 30 μg/dl blood lead levels with maximum lead effect at Digit symbol’s score at 40 μg/dl. In conclusion, this study is consistent with the larger body of neurobehavioral tests in lead exposure and has proven the ability of these tests in detecting low level of lead toxicity.

    This study aimed to validate the Malay Version of Copenhagen Psychosocial Questionnaire for Malaysian use and application for assessing psychosocial work environment factors. Validity and Reliability were studied in 50 staff nurses of Hospital Selayang. The validity of the questionnaire was evaluated by calculating the percentage of sensitivity and specificity at the different score level. Both percentage of sensitivity against specificity were plotted to produce a ROC (Receiver Operating Characteristics) curve, and score 52 has the highest both sensitivity and specificity was used as an overall index that expresses the probability that measure the psychosocial problems. For reliability purposes, a descriptive of Test-Retest Mean Scores and Paired Sample T-Test and the coefficient-correlation test were calculated. The Test-Retest Mean Scores and Paired Sample T-Test for all 26 scales were calculated and showed statistically not significant. The reliability of the questionnaire and its 26 scales was assessed by using Pearson (r) (overall questionnaire r within a range of 0.00 to 1.00). The COPSOQ appears to be a reliable and responsive measure of workers for Malaysian use and can be applied for assessing psychosocial work environment factors.

    Emergency in a major hazard installation may cause extensive damage to property and serious disruption both inside and outside the installation. The overall objectives of an emergency plan are: to localise the emergency and, if possible, eliminate it; and to minimise the effects of the accident on people and property. The off-site emergency plan is an integral part of any major hazard control system. In many countries the duty to prepare the off-site plan lies with the local authorities, including Malaysia. Thus, the preparations of written off-site emergency response planning is required to minimize the impact of major accident to the people , property and environment.

    The construction industry is an important industry in the Malaysian’s economy. Much has been said about the quality of the product as well as the image of the industry due to the small percentage of local workers on site. The industry’s welfare and safety record is not at all encouraging. To stop the rot, the government has taken important and significant steps by the establishment of the Malaysian Construction Industry Development Board (CIDB) and the National Institute of Occupational Safety and Health (NIOSH). These efforts have shown some significant positive improvement in the perception and action of those involved in the industry but we are still far from the standard shown in other developed countries in terms of site safety. This paper is to discuss the roles and responsibilities of the key players in the industry be it the clients, consultants or contractors. The focus is on the ‘upstream’ activities i.e. the pre-construction stage, rather than the ‘downstream’ i.e. the construction phase of a project.

    In general, the industrial accident rate in Malaysia is decreasing. However, statistically it is still relatively high
    if compared with that of other developing nations. One of the reasons why accidents keep on happening is poor
    learning from accidents. This paper discusses the level of accident learning, based on accident reports submitted to the
    Department of Occupational Safety and Health (DOSH) Malaysia and the Society Security Organization (SOCSO)
    Malaysia involving a total of 1,291 accident cases. Based on the quality and completeness of accident reports, the
    levels of learning were classified into five accident causation levels which are no, limited, fair, good and excellent
    learning.

    Recent development in industrialization and global economy has contributed to the increased number of workplace
    injuries and accidents. Safety culture has been seen as a central medium to curb the worrying trend of workplace
    accidents. The term of safety culture has emerged from the Chernobyl nuclear disaster in 1986 and the concept has
    been widely used until today. However, the conceptualization of safety culture suffers from several major drawbacks
    such as no definite understanding of how safety culture is being defined and measured. This paper hypothesized that
    higher levels of safety culture in the workplace will display lower numbers of accidents. Due to this concern, this
    paper seeks to provide a clear conceptualization of safety culture, dimensions used to measure it and common research
    methodology used in the previous safety research.

    The light train (LRT) is one of the important public transportation modes in the congested city of Kuala Lumpur. Train drivers drive the trains within their shift time on similar routes every day. This job activity may lead to stress. Physical fatigue is one of the health problems commonly experienced by the train drivers. There were three methods applied in this study, namely, Nordic Questionnaire, NASA-TLX and observations. There were a total of 52 respondents, consisting of the train drivers from Rapid Rail Sdn Bhd, a subsidiary company of Prasarana Malaysia Berhad. The questionnaires were analyzed using Statistical Software for the Social Science (SPSS) with a suitable statistical analysis. It was found that, the train drivers experienced pain on their necks, shoulders and lower backs. The main causes of physical fatigue that affect the performance of a train driver are sleep disorder and uncomfortable seating. Moreover, other effects of physical fatigue also prevent the drivers from carrying out activities at home. The industry has improved the drivers’ workstations such as their seats to reduce the rate of physical fatigue. However, more improvements are expected to be done.

    The energy price increased significantly since the early 1970’s and it shows the pattern of all over the world.
    According to the estimation of International Energy Agency (IEA), 53% global energy consumption will be increased
    by 2030, with 70% of the growth in demand coming from developing countries. Malaysia is one of the most developing
    countries among ASEAN countries next to Singapore, with GDP of US$15,400 per capita (PPP basis), and steady
    GDP growth of 4.6% in 2009. Malaysia as a developing country focuses on the energy efficiency approach. At this
    moment a lot of number of fire and electrical incident more towards overload current and the issues has been faced
    trough out the year. This paper highlight the issue on how to avoid the overload current by introducing the method
    establish by Energy Commission. The star (*) rating will help us to estimate the current use and the energy efficiency
    approach by calculate the current load. The data collected from home appliances are the very basic information rather
    than predict in a large scale as industrial and commercial building since the tariff also different in the category. The
    equipment such as amp meter, volt meter and the current load data logger will help the current consumption in every
    home appliances and it will show the direct reading as well. The issue on electrical safety should be response by
    consumer to prevent safety and health risk.

    Indoor air pollution is rapidly becoming a major health issue worldwide. The quality of indoor air inside building
    is important not only for occupants’ comfort but also for their health. Although researches are still under way to
    better define the nature and extent of the health implications for the general population, recent studies have shown
    significant amounts of harmful pollutants in the indoor environment. Poor indoor air quality (IAQ) has been tied to
    symptoms like headaches, fatigue, trouble concentrating and irritation of the eyes, nose, throat and lungs. In this study,
    occupants’ comfort satisfaction on IAQ of a museum building environment in a tropical climate will be studied. IAQ
    aspects which will be considered as parameters are chemical contaminants, gaseous pollutant and comfort factors
    (temperature, humidity and air movement). Museum, archives, library, heritage building and gallery are the types of
    buildings that can be considered as heritage building environment. At the initial stage, a pilot study will be conducted
    to identify the current IAQ conditions inside those selected buildings.

    Indoor Air Quality (IAQ) is a subset of Indoor Environmental Quality (IEQ), where IAQ is about what we
    breath. Poor indoor air quality (IAQ) can cause health problems to the residents. Air conditions in the shelter must
    be preserved, in order to ensure the safety and health of the residents. Certain indoor plants can filter out toxin found
    in the air. Other than that, indoor plants can help clean the air. In this study, seven types of indoor plants that can live
    in equatorial climate like Malaysian environment will be selected. At the initial stage, planting of all types of indoor
    plants will be done, from sowing seed until all plants grow up. In the next stage, all plants will be tested to determine
    their effectiveness to improve indoor air quality. The comparison of data before and after installation of indoor plants
    is made. To gain the benefits of indoor plants, detailed study should be done in terms of response and monitoring of
    indoor air. The reason of this study is to provide benefits to building occupants. Besides, having the interior plants as
    part of decoration items may improve workers’ productivity and reduce stress.
