The unpopularity of the current hard hat among oil palm harvesters stemmed from the discomfort from wearing, which showed that the development of a new hard hat could lead to better usage and the greater likelihood of wearing a hard hat throughout the working day.

This study found that the workers had good KAP levels of risk management of steam boilers in palm oil mills. However, there is a need for the employers to revise the training of workers and ensure its effectiveness in heightening the awareness of risks and accidents despite the high level of KAP.

Introduction: Indoor air quality is an important aspect in defining Sick Building Syndrome (SBS). SBS triggered by inadequate IAQ may harm occupants. Objective: This study was conducted to establish the relationship between IAQ and SBS in the higher educational building. Methods: The research method is divided into three main categories; indoor air chemical and contaminant analysis, microbiological contaminant analysis, and questionnaire. A cross-sectional study was conducted at seven locations in a university in Shah Alam. Results: The results were compared to the Department of Occupational Safety and Health standard (DOSH). Significant correlation with temperature (p<0.05), relative humidity (p<0.05), and particulate matter (PM10) (p<0.05) were found.This study suggests that enhancing housekeeping standards and monitoring indoor air quality can enhance the indoor air quality in Malaysian higher education buildings. Conclusion: Based on correlation between IAQ and SBS symptoms, poor IAQ and SBS symptoms among occupants may impact teaching and learning process in the university. Conclusion: This study suggests that enhancing housekeeping standards and monitoring indoor air quality can enhance the indoor air quality in Malaysian higher education buildings.

Objectives Designs for low-cost air monitors and associated performance data appear in many peer-reviewed articles; however, few manuscripts provide feedback from end user's experiences or comprehensive evaluation. The present study addresses the usability of the wireless outdoor individual exposure indicator system from the viewpoint of the Malaysian Traffic Police (end users). This study is one of the first to chronicle end user experiences for low-cost pollution sensing. Method The evaluation involved 12 target end users to assess the usability of a prototype for Malaysian Traffic Police to manage their exposure to outdoor air pollution. The test evaluation includes a pre-test, post-task and post-test questionnaire (Post-Study System Usability Questionnaire). The main components in this Post-Study System Usability Questionnaire are Overall satisfaction, System Usefulness, Information Quality and Interface Quality. Findings The results of the Post-Study System Usability Questionnaire indicated the mean score of the Overall satisfaction item (2.33), System Usefulness (2.25), Information Quality (2.36) and Interface Quality (2.17) on a scale of 1–10. Prototype users were satisfied with the system because the score is close to 1 on the Post-Study System Usability Questionnaire. Conclusions A user-friendly wireless outdoor individual exposure indicator system is now available for Malaysian Traffic Police. Users have stated that they are happy to use the system at work. However, in addition to more technological advances, practical implementation requires evidence supporting its efficacy, viability and effectiveness.
