    This study aims to investigate a visual status and prevalence of visual problems in relation to eye safety and health amongst
    visual display terminal (VDT) users in industries. A visual profile questionnaire (VPQ) and visual tests were conducted on workers
    from 9 type of industries aged 20 to 60 years old in between October 2015 and June 2016. Workers with a history of exposure to VDT
    more than 2 hours a day were used as a baseline for recruitment. Respondents who did not complete the visual profile questionnaires
    (VPQ) and visual tests were excluded from the study. A total of 1214 respondents with mean aged of 39.33 ± 9.80 years have completed
    the study. Most respondents show moderate to high in vision problems in related to VDT, low knowledge on visual hazards and policy
    in relation to eye safety and health at the workplace and high percentage of not getting proper eye tests while serving their industries.
    Visual Profile (VP) is needed as a key indicator to profile eye safety measures and the need for policy to help prevent eye problems and
    improve employees’ productivity at workplace.

    Evacuation profile systems in high rise building are important to determine the safety level during any fire
    emergency. In relation to this, the study was conducted with its objective to develop the evacuation profile for
    NIOSH Tower. Evacnet-4 software was used to develop models for building evacuations using the building network
    descriptions and the initial content of the occupant at the beginning of the evacuation. The results show that it
    requires 390 seconds to evacuate NIOSH tower, with the highest number of bottlenecks recorded for the Third Floor.
    Identification of bottleneck is important to determine the evacuation periods. The information gained from the model
    may be used for the emergency response planning and for support material. The model should be tested in real time
    to have its reliability verified.

    Working in a safe working posture is a necessity to enhance occupational health of industrial workers. Poor
    working posture may lead to injuries, discomfort and fatigue to the workers. The objective of this study is to survey the
    postures practised by the Malaysian industrial workers. A questionnaire survey was performed among 282 Malaysian
    industrial workers in 10 different industries. From the answered questionnaire, it was observed that shoulder at chest
    level (30.1%), back in a bent forward (33.3%) and lifting heavy load (44.7%) are the major work postures practised by
    most of industrial workers. This survey identifies that working with shoulder and hand at chest level and back region
    moderately bent forward is the main working posture practice by worker. Workers also reported lifting load below 5 kg
    at the workstation. This survey recommended for industrial workers to be aware of the comfortable working posture
    to avoid injury.

    when used while standing. The important parts in this invention are rostrum head and platform. The rostrum head is
    adjustable so the users can set the height of rostrum head for their suitability and comfort. Another important part in
    this invention is platform. The purpose of the platform is to help users reach the rostrum head. The platform can flip
    into the rostrum body. This invention can be used by anyone especially for Malaysian people because its designed was

    This study aims to assess the level of Knowledge, Attitude and
    Practices (KAP) on Musculoskeletal Disorders (MSDs) from employer perspectives
    in Malaysia industries. A developed KAP questionnaires were distributed and
    returned by 39 employers. Most employer show good scores to majority of items in
    Knowledge and Attitude sections. However, good practices are still lacking as the
    scores are quite low for half of the items. Kruskal-Wallis test for independent sample
    was used to test the relationship between gender and KAP scores. It was found out
    that gender is linked with few items in Knowledge and Attitude section (r < 0.05)
    while no indication of relationship with Practice scores. As the number of reported
    MSDs cases are increasing in Malaysia, hence understanding of KAP factors are
    crucial in order to tackle the problem.
