Some have put the blame on the government for inadequate laws and road unworthiness. Others blamed the drivers for being ‘cash crazy’ and reckless while others have blamed the companies for hiring drivers that are not qualified and not putting safety policies in place. In all these cases, the degree of accidents that had taken place on these roads is alarming and someone therefore has to shoulder the responsibility for there to be a change. This article reviews the concept of the law of negligence citing cases of negligent behaviours from all partiesinvolved. The aim of this article is to create awareness on the ongoing cases of accidents, both reported and unreported for government intervention and to raise public awareness.

This postural alteration contributes to awkward posture, musculoskeletal disorders and spinal injury, especially in the lower back area, as it is one of the most severe modern diseases nowadays. Thus, the study aimed to evaluate the effect of lumbar support with a built-in massager system on spinal angle profiles among traffic police riders. A randomised controlled trial (pre-testpost-test control design) was used to assess spinal angle pattern while riding the high-powered motorcycle for 20 minutes. Twenty-four traffic police riders were randomly selected to participate and 12 riders were assigned to the control group and 12 riders to the experimental group. The pre-test and post-test were conducted at a one-week interval. Each participant was required to wear a TruPosture Smart Shirt (to monitor spinal posture). The TruPos...

This field analytical study was conducted to determine dermal contamination of spray operator during pesticide application under the influence of difference spraying flow rate at the rice farming village of Selangor, Malaysia. The fluorescent tracer technique was used to quantify the dermal contamination pattern of the spray operator, followed by quantifying the concentration of fluoresceine with the aid of digital fluorometer. In summary, the mixture of pesticides applied to the farmland with higher spray rate (L/min) showed an increased contaminant doses retained on the body surface. In summary, it is recommended that changes in application techniques, setting up buffer zones or selection of low spraying flow rate (L/min) could improve the efficacy and safety of pesticide contamination through dermal pat...

Even though BPA is not involved in polyethylene terephthalate (PET) manufacturing, recent study had reported the present of BPA in PET water bottle. This study was conducted to investigate effects storage conditions on release of BPA from PC and PET bottled water as well as to assess health risks associated with consumption. Methods: Solid phase extraction (SPE) was used to extract the samples, followed by analysis using ultra high performance liquid chromatography with fluorescence detector (UHPLC-FLD). The possibility of developing chronic non-carcinogenic health risk among consumers of bottled water was evaluated using hazard quotient (HQ). Results: Results showed that BPA migrated from PC and PET water bottles at concentrations ranging from 9.13 to 257.67 ng/L and 11.53 ng/L to ...

Several methods of extraction had been applied to extract PAHs from human blood samples such as solid phase extraction (SPE). The SPE represents one of the most common techniques for extraction and clean-up procedures as it needs low quantity of solvents with less manual efforts. Similarly, various analytical instruments like gas chromatography coupled to mass spectrometry (GC-MS) was used to measure the PAHs levels. Gas chromatography is a simple, fast, and very efficient method for solvents and small organic molecules. This review provides an overview of the measured concentrations of PAHs in human blood samples through the application of SPE and GC-MS during the last ten years. While these studies used various solvents, their application of SPE method and GC-MS revealed rewarding results about the determination of PAHs levels in the human samples.

Educators who are lacking disaster education background always find it difficult in knowledge delivery and trigger learners' curiosity in disaster learning. Therefore, this study aims to evaluate the effectiveness of knowledge transfer in disaster learning among school children by using two different learning methods with the same learning module. Methods: Two different learning methods, i.e. a customized learning kit and PowerPoint teaching slide were used in this pre-post intervention study. The prototype of the customized learning kit was developed based on the psychosocial development of children that emphasized the importance of “children play” in early childhood education. A total of 337 elementary school children a...

Schools that are supposed to create a safe learning environment for students have become a vulnerable place when hit by flood during school hours. Children would be in danger if facing with a flood situation without parents or adults with them to help and lacking in the knowledge and preparation in response toward flood disaster. This paper discusses the potential of developing a personalized child-focused and child-led disaster risk reduction educational approaches and techniques. This was done by intervening the customized flood education miniature and interactive e-learning into a disaster educational module to evaluate the school children’s flood preparedness knowledge levels. A quasi-experimental study was carried out among 110 schoolchildren whose school and house are located at the flood-prone areas. The prototyp...

Evidently, extant, yet very limited empirical underpinnings suggest that knowledge, practices and awareness of safety precautions are uncharacteristically poor among laboratory workers. As such, their demonstration of safety-related attitudes and practices have remained questionable. This paper, thus presents a systematic search of the literature on laboratory workers’ safety-related knowledge, attitudes, and practices. Specifically, literature published between 2007 and 2017 that characteristically attempted to evaluate knowledge, attitudes and practices among laboratory workers on Occupational Safety and Health were reviewed. Evidently, results from the review indicate poor knowledge, attitude and practice among the laboratory workers. It is critical that strategies be put in place by the management of the health facilities to institute and undertake activities in the form of training, improved safety manag...

In order to close the gaps that exist in the current OSH policy system, both employers and employees in any business organization are urged to demonstrate full commitment on OSH programs and plans. This paper aimed to summarize the latest OSH policy updates under the government bodies and agencies in Malaysia that affect business activities in all organizations. It is hoped that with these important policies made, the safe and healthy working culture would be positively implemented at the workplaces. To date, the rapid economic transformation in Malaysia requires more proactive insights into the OSH policy and mechanisms, to fulfill the demand of the rapid developmental goals. The summary findings of this OSH report overview could serve as the reference point to understand the development and gaps present from the ye...

Traffic police is a high-risk occupation that involves a wide range of tasks and, indirectly, faced with an equally wide variety of hazards at work namely, physical, biological, psychosocial, chemical, and ergonomic hazards. Thereupon, occupational injuries, diseases, and even death are common in the field. The objective of this paper is to collate and explain the major hazards of working as Malaysian traffic police especially in Point Duty Unit, their health effects, and control measures. There are many ways in which these hazards can be minimised by ensuring that sufficient safety measures are taken such as a wireless outdoor individual exposure indicator system for the traffic police. By having this system, air monitoring among traffic police may potentially be easier and accurate. Other methods of mitigating these unfortunate events are incorporated and addressed in ...
