This paper aims to investigate the potential pesticide dermal contamination among the agricultural community by observing the microenvironmental and macroactivity interaction between farm children and adult farmer. A 24 hours timeline activity was observed and recorded in the agricultural farming village, Kuala Selangor. In this study, 2 homes were monitored for 2 days following a pesticide application. A total of 2 adult farmers and 5 children (7-10 year old) were recruited to participate in this study. Twenty-four hour videotape segments and time-activity diaries were collected during the study. The microenvironment and macroactivity interaction were modelled in this study. By considering only the potential dermal exposure pathway, the different biological vulnerability and exposure pattern to pesticides were observed. Finding showed a greater extent of interaction between human and its environment, where adult farmers are the main contributor of environmental contaminants, and children is one of the vulnerable receivers of the contaminants’ residuals from the environment. The daily activities and behaviors practiced by the agricultural community were among the contributing factors which help to highlight the pesticide dermal contamination pathway in the farming village. This study recommends the necessary to consider the microenvironment and macroactivity of the target community when assess their exposure levels to the environment contaminants.​

Introduction: School can be considered as a relatively moderate risk working environment due to the various hazards assembled in the school. Nevertheless, Occupational Safety and Health (OSH) training is yet to formally inclusive into teachers’ training module, and the current one-off or ad-hoc OSH training mainly targeted among school students. The different OSH awareness exists among teacher and student have hinder the provision of sustainable and effective safety and health training program at school levels. Objective: To assess the knowledge, attitude and practice among primary and secondary school teachers towards OSH at the school environment. Method: A cross-sectional survey carried out at three (3) primary schools and three (3) secondary schools after stratified random sampling. School teachers from these schools were randomly selected among those who had at least one year work experience as permanent teacher at the current school through the fishbowl technique. A structured questionnaire was used and total 136 teachers were assessed on their knowledge, attitude and practices on OSH at schools. Result: Study found that primary and secondary school teachers have different knowledge, attitude and practices of OSH at school levels. Overall, the knowledge level of secondary school teacher (62.1% of high to medium knowledge levels) are higher than the primary school teachers (41.1% of high to medium knowledge levels); at the same time, 93.1% of secondary school teachers show positive attitude while 88.5% of primary school teachers show positive attitude on safety and health at schools. In general, OSH practice level among the primary (88.5%) and secondary school teachers (86.2%) are at relatively good levels. Besides, there is positive association with knowledge and attitude on OSH behavior among primary school teachers. Apart of this, there is positive but relatively weak association with knowledge and practices and knowledge and attitudes among primary and secondary school teachers. Conclusion: Considering the background differences between primary and secondary school teachers, a sustainable OSH learning mechanism should be planned and designed together with OSH practitioners and Ministry of Education to achieve a sustainable safety and healthy sound school environment for teacher to work and for students to learn.

Introduction: Tanjung Karang is a paddy growing town in Selangor, Malaysia. The paddy farmers in Tanjung Karang were using pesticides to control pests from invading the crops during agricultural activities with limited knowledge of its deleterious effects on their health. Objective: This study aims to (i) determine the respiratory health symptoms of paddy farmers due to occupational exposure of commonly used pesticides through inhalation and (ii) assess correlations between climatological conditions and the concentrations of pesticides in personal air samples among paddy farmers in Tanjung Karang, Malaysia. Methods: A cross-sectional study was carried out to assess the occupational exposures to pesticides among 83 paddy farmers in Kampung Sawah Sempadan. The data were collected with face-to-face interviews with the farmers based on a set of questionnaire. Results: The self-reported respiratory health symptoms of paddy farmers were as follows: breathing difficulty (16.9%), chest pain (15.7%), cough (41.0%), phlegm (39.8%), and wheezing (18.1%). Simple logistic regressions analysis indicated that exposure to azoxystrobin, buprofezin, chlorantraniliprole, fipronil, isoprothiolane, pretilachlor, propiconazole, tricyclazole and trifloxystrobin were contributing factors that affect self-reported respiratory health symptoms in this study. Spearman’s correlation coefficient test stated that the concentrations of chlorantraniliprole, fipronil and pymetrozine were affected by wind speed and temperature. Conclusion: The information obtained in this study is useful to understand the exposure of pesticides among paddy farmers and useful for risk management in the agricultural community.

Abstract Introduction: Malaysian traffic police are always working on the public roads to alleviate traffic congestion and therefore exposed them to the polluted air every day. In particular, polluted air containing PM2.5 is dangerous to their respiratory health as they can penetrate deep into the lungs, leading to bronchitis, lung cancer and many more. Hence, this research examined the relationship of personal exposure level to PM2.5 with respiratory symptoms among traffic policemen in Kuala Lumpur and Johor Bahru. Methods: 134 participants among traffic policemen were agreed to participate in this study. They were requested to complete a questionnaire regarding the sociodemographic background and respiratory health information. The questionnaire was adopted from International Union Against Tuberculosis Lung Diseases (1986). Personal exposure level of PM2.5 was measured using an air pump with 5.0µm pore size PVC filter. Results: The mean exposure level of PM2.5 among traffic policemen was 28.69 µg/m3. It was found that some of them possess respiratory symptoms (Coughing 33.6%, Phlegm 25.4%, Wheezing 14.9% and Shortness of breath 32.1%). There was significant association detected at p-value < 0.05 in coughing. Despite, there was no significant association in other symptoms such as phlegm, wheezing and shortness of breath. Conclusions: Traffic police were exposed to a relatively high level of PM2.5 (12.4 µg/m3 to 55.3 µg/m3) and showed symptoms of respiratory effects. Therefore, recognition of the risks connected with occupational lung disease and exposure monitoring must be a high priority. This baseline data can serve as a reference to the top management of traffic police officers in order to develop an occupational safety and health guideline for police officers as required by Occupational Safety and Health Act (OSHA, Act 514 1994).

Abstract Discomfort measurement has usually been attempted by asking the participants to rate the scale of their discomfort which commonly termed as a subjective scale. Various studies had conducted the discomfort level on vehicle seat by using Visual Analogue Scale (VAS) and Likert scale. VAS is a tool that use to measure a discomfort or characteristics in range across a continuum of values. Meanwhile, Likert-scale is a tool consist of items that require respondents to rate their degrees of comfort or discomfort with various declarative statements. Thus, the purpose of this study is to review, discuss and compare between the VAS and Likert scale used on the development and assessment of sitting discomfort survey in seat vehicles. The literature on various topics related to questionnaire development on discomfort in seat vehicle were collected from electronic databases. Four high-quality studies were eligible and met the inclusion and exclusion criteria. Overall, there is no evidence and conclusion that neither visual analogue scale nor Likert scale are better to one another. Therefore, it can be concluded that either of this scale still applicable for the ergonomic research application as both of this scale have their own pros and cons.

Background: Occupational Safety and Health Master Plan for Malaysia 2015 was intended to increase awareness, knowledge and commitment to Occupational Safety and Health in all undertaking to reduce the number of injuries, diseases and fatalities. Objectives: The purpose of this study is to determine the effectiveness of Occupational Safety Health Master Plan for Malaysia 2015 (OSH-MP 15) in enhancing government leadership and preventive workplace culture. Methods: This cross sectional study covered all the states in Malaysia, constituting of 309 employers, 350 Occupational Safety Health practitioners and 360 employees as respondents. There were three questionnaires for three different groups which were employers, Occupational Safety Health practitioners and general employees. The respondents were selected through random sampling. Results: For strategy 1, there was a significant difference in mean of effectiveness of OSH-MP15 between sectors for general workers [F (11, 348) =12.06, p=<0.001], OSH practitioners [F (11, 338) =1.19, p=0.033] and employers [F (11, 297) =5.62, p=<0.001]. For strategy 2, a significant difference in mean of effectiveness of OSH-MP15 between sectors was found for general workers [F (11, 348) =4.52, p=<0.001], OSH practitioners [F (11, 338) =2.28, p=0.011], employers [F (11, 297) =5.74, p=<0.001]. Conclusion: There was a significant difference between the effectiveness of fostering, and enhancing government leadership and inculcating preventive workplace culture among respondents. This study acts as the baseline data for the effectiveness of Occupational Safety and Health Master Plan 2015 in enhancing government leadership and preventive workplace culture.Keywords: Occupational Safety; health; leadership; prevention; accidents

Background: Quality of Work Life (QWL) is a subset of the quality of life which expresses the interactions between workers and their total working environment with individual or human dimension. Objectives: The objective of this study was to determine the prevalence of QWL among Malaysian workers. Methods: 2740 respondents (1921 males and 819 females) were randomly selected from 11 different industries from all states of Malaysia. Respondents were aged between 18 to more than 55 years and were a local OSH Personnel and local general workers. Face to face interviews were conducted in all the selected industries using a structured questionnaire form adapted from Malaysian OSH Profile 2016. Respondents have completed the questionnaire under instructions and supervision of the research team. Results: Majority of the respondents were male (70.1%) and from manufacturing industries (76.3%). 50% of the respondents identified a high level of QWL in each component like not having a stress with the work load (85.5%), good work environment (78.4%), family life (83.1% and 83.6%), enough income and distribution (58.9%), good communication and harmonies relationship between colleagues and boss (93.4% and 88.7%), good facilities (88.6%), welfare at work (71.3%) and productive working condition (80.8%). There is a significant difference between QWL and type of industries [F(10)=12.897, p=0.001] where agriculture industry had the highest QWL. There is significant difference between QWL and gender (p=0.009) where male reported higher QWL compared to female. Conclusion: These findings could be used by the organizations in order to enhance its performance, productivity, employees’ commitment and satisfaction.

In order to accomplish a wide range of duties and responsibilities that may be done under unpleasant working conditions, prolonged standing posture is common with school teachers. Nevertheless, standing upright for a long time or otherwise regarded as prolonged standing frequently contributes to body pain and discomfort, muscle fatigue and even health problems such as musculoskeletal disorders (MSDs). The aim of this paper is to review MSDs arising from prolonged standing and spread information on existing ergonomic and non-ergonomic interventions to alleviate prolonged standing discomfort. Systematic review on prolonged standing school teachers with specific keywords were recognized to discover the appropriate studies and information in a systematic search. The informations in this review may be helpful to guide teacher, school management and researchers to implement the suitable interventions in order to minimise the health issue due to MSDs among school teachers.

Laboratory workers exposed to diverse occupational exposures to accidents. 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 management practices, organizational commitment and improved safety culture.
