Regulation on occupational safety and health in Malaysia had evolved from the prescriptive Factory and Machinery Act (1967) to a self-regulated Occupational Safety and Health Act (1994). However, from the authors’ observation the high standards of occupational safety and health culture that surpass the legal requirement were not widely practiced by small and medium enterprises (SMEs). The two main objectives of this study are: first, to identify and determine the level of conformity; and second, to investigate the reasons of nonconformity to Occupational Safety and Health Act (1994) regulation in SMEs involved the chemical industry sub-sectors. The survey questionnaire was distributed to 150 SMEs in chemical industry sub-sectors. Forty one of the survey questionnaires were completed and returned, giving a response rate of 27.3% for the survey. The survey results revealed that an overwhelming majority (92.7%) of the respondents from SMEs are likely not conforming to the basic requirement of Occupational Safety and Health Act (1994). In addition to this, the survey also found that only 3.1% of the management personnel can be considered competent in terms of knowledge, skill and ability in carrying out occupational safety and health regulation within their respective organization. While, 96.9% of the respondents that participated in the survey can be considered not competent. The authors hope the result of this survey could assist the relevant authorities in formulating a better policy and strategy for implementing occupational safety and health in SMEs involved in chemical industry sub-sectors.
Working environmental conditions in automotive industry are very challenging to the human workers. Meanwhile, products quality is very much dependent on workers’ health, safety and comfort in their working environment. Environmental factors, such as temperature, illuminance and humidity levels have significant effect on workers’ performance at the production line. In this experiment, temperature, humidity, illuminance levels and productivity rate were observed in a control room. An automotive manufacturing firm production line was chosen to be simulated in the control room to observe the temperature, relative humidity, illuminance and worker’s productivity rate. The experimental data collected was analyzed using Response Surface Method (RSM). RSM is an analysis technique, which combined statistical systems and mathematical methods. It can be applied for research and development, reform and optimize a process, which involves several design variables. As a result, the combined effect of temperature, illuminance and humidity toward productivity can be clearly seen. Optimum environmental factor cannot be predicted using first order RSM analysis because it gives low reliability for obtaining the optimum level. Thus, a second order RSM analysis was generated for obtaining the optimum level of environmental factors.
Environmental factors such as temperature, lighting and noise have very significant impact to workers’ health, safety, comfort, performance and productivity. In an ergonomically design industrial work environment, these factors need to be control at their optimum levels. The main objective of this study is to find the effect of temperature, illuminance and sound pressure level on workers’ productivity in automotive industry. To perform this study a workstation in an automotive component manufacturing was selected as the location of the study. Results of data analysis showed there were relationships between temperature, illuminance and noise on workers’ productivity. Later, the authors’ developed multiple linear equation models to represent the relationships between temperature, illuminance and noise on the workers’ productivity. These multiple linear equation models could be used to predict the production rate for the workstation by referring to the value of temperature, illuminance and noise level.
Anthropometric Test Devices (ATDs) of different nominal percentile values have long been used as human surrogates in automotive crash testing. The Hybrid III family, which is one of the widely used ATDs in frontal crash test, was designed based on the anthropometry dimensions of US adults. Thus, this paper aims to assess the anthropometric differences between Malaysian adults and Hybrid III dummies in terms of 5th percentile (small female), 50th percentile (midsize male) and 95th percentile (large male). A series of anthropometric parameters of Malaysian adults was obtained from a database of 1321 subjects with 708 males and 613 females. The results revealed that the current midsize male population differs from the ATD’s statures and body weights by about 35 and 40 percentile points, respectively. This demonstrates that the current ATDs are not truly representative of the current Malaysian adults, which may potentially lead to different injury responses in road traffic crashes. Thus, car manufacturers may as well consider this discrepancy issue in developing their future models especially with regards to safety.
Agricultural activities have always been associated with hazards and injuries. Most common injuries experienced by workers are health, safety and ergonomic injuries. It stems from many causes, such as the use of manual tools, incorrect working position, inadequate rest and overloading. This paper aims to reveal the daily hazardous work task of oil palm plantation workers with highlighting the ergonomics problems and risk of injury they faced. Observations of work tasks and distribution of Modified Nordic Questionnaire (MNQ) were performed for every work unit. Worker’s activities and posture while performing work tasks were recorded extensively using camera and video recordings for ergonomics analysis. Results from the observation and questionnaire survey conducted, showed that oil palm plantation workers are exposed to the risk of dangerous work every day. Fresh fruit bunches cutter and loose fruit collectors were having highest body pain complaints and almost from them are having low back pain problems. Therefore, it is necessary for an immediate action from the management in order to determine the current prevalence of ergonomic injuries. Using of manual tools should be avoided and plantation workers should be provided with ergonomics machines that can help them reduce their workload and injuries.
Drivers’ posture is one of the factors that can contribute to driving discomfort. Subjective evaluation is needed in determining the driving discomfort problem. The purpose of this study is to examine the reliability of different driving postures that may lead to drivers’ discomfort. A total of thirty-four healthy Malaysian drivers were involved in this study. Respondents were required to sit on the driver’s seat with the required adjustments of three different postures and fill-in the given subjective evaluation form. The same procedure was repeated for each respondent after three days for purpose of conducting test retest evaluation. The reliability statistical analysis result shows the study was reliable and valid with a Cronbach’s alpha coefficient equal to 0.827. The comparison means that ANOVA analysis also shows significance difference between these three groups of postures for all measured parameters. In conclusion, the result from this study shows the subjective evaluation conducted is reliable and can be used for drivers’ posture discomfort study.
Development of ergonomic sofa design is a design process that has the basic framework specification and type of
material that is applied on the sofa design. This is due to human consumption that is closely related to ergonomic
design of this specification which will affect human physical. To achieve this goal, a survey involving 30 respondents
of sofa makers was conducted to get feedback regarding the sofa design specifications. Survey questions emphasize
on the basic specifications and material dimensions of sofa materials used. The results of data analysis show that the
size of basic dimensions and materials is essential in designing an ergonomic sofa. The survey is very important to
find out the basic specifications in the development of ergonomic design through perception of sofa maker.
Substantial studies reported musculoskeletal disorders among the working population in the developed country, however, a limited number of studies were conducted in Malaysia. The objective of this cross sectional study was to determine the physical activity risk factors for low back pain among automotive workers in Selangor. Modified Risk Factors Questionnaire (RFQ) was used to assess physical activity with the occurrence of low back pain. The significant physical activities associated with the 12 months point prevalence are lifting weight (
Introduction It is well known that low back pain among working population is a global
problem throughout the world. However, the current situation of occupational
low back pain in Malaysia is still vague due to limited number of studies
conducted locally.
Objective A cross sectional study was conducted among three automotive industry
workers in Selangor, Malaysia from October 2010 to April 2011.
Methods This study aims to determine the prevalence and risk factors of low back pain
among automotive industry workers performing manual material handling
tasks using self-administered questionnaire survey.
Results A modified Standardised Nordic Questionnaire was used to assess low back
pain problem, to obtain personal and psychosocial risk factors information.
The prevalence of low back pain showed increment in the point prevalence of
57.9%, 49.5%, and 35.1 % for 12 months, one month, and of 7 days
respectively. Working hour, frequency of overtime, stress at work, work
pace, and faster movement were found to be significantly associated with the
12 months prevalence for low back pain.
Conclusions This finding indicates that psychosocial risk factors are associated to the
occurrence of low back pain.
Mobile phone distraction is a global issue in road safety perspective especially involving the pedestrians. A lot of
research findings had suggested that the use of mobile phone increase the risk for pedestrians while crossing the
road, but there have been very few studies that could explain the said threat in Malaysia’s situation. This study aims
to identify the distracted pedestrian behaviour via the video recording method. More than 300 samples were
observed as involved in mobile phone distractions while crossing the roads from a total of approximately 1,500
analysed samples. The study also found that the highest mode of distraction observed among pedestrians was the
“handheld usage” (conversing) as compared to the “hands-free” and “application usage” modes. In addition, the
distractions had significantly affected the time to cross and the observed road users who were involved in
“application usage” took longer time to cross. These results provide a prevalence material that may be useful in the
development of countermeasures.
Validity test is important during the development of ergonomics measurement. Failure to conduct validity tests will result in the measurement method being developed to be incapable of providing reliable ergonomics measurements. The objective of this study is to conduct validity test on the simple method ergonomics measurement which was developed. The method named Simple Ergonomics Risks Assessment (SERA). Content validity test and criterion validity test were conducted. The content validity test consists of 6 ergonomics experts who actively provide inputs and positive feedbacks to improve the measurement method being developed. Meanwhile, the criterion validity test involves data collection of complaints on body parts among oil palm workers which were derived from Nordic Musculoskeletal Questionnaire (NMQ) and ergonomics risk assessment scores obtained from SERA. Both findings were tested with the Chi-square test to explore possible relations between the two findings. Results from the test conducted showed that there are significant relations in the scores of neck posture; hip, right and left shoulder, right and left wrists and the right hand associated with fresh fruit bunch (FFB) harvesting activities. In the loose fruits collection, the Chi-square test showed significant relations in the scores of neck posture, hip, right and left shoulders, right wrist, right arm and the left hand. However, there are body parts such as the legs which showed no significant relation. More tests should be conducted to further explore the validity of the method being developed. Findings from both validity tests show that SERA were verified by the experts and tested with validated method so that it is valid to be applied in the future.
The main purpose of this study was to establish the comfort zone for bus drivers in a seated position. In addition, this study is to investigate the seated pressure distribution among Malaysian bus drivers. The study consists of 10 bus drivers randomly selected to be a part of this study. The FSA pressure mat was utilized in order to investigate the force distribution of buttock to the seat pan of the drivers’ seat. This device is placed on the driver seat and backrest. Later, the subject would sit on for several minute. The finding reveals that most of the bus drivers feel discomfort by having low back pain and musculoskeletal disorder. The seat pressure distribution of Malaysian busses indicated that the seat not able to absorb high pressure generated from buttock that later may cause the discomfort and restricted the performance of drivers.
Road transport is the movement of passengers or goods on the road. To date, issues concerning the safety of students
and school institutions have continued to attract public attention. The recent spate of incidents inside and outside
the school compound has brought the issue of children safety into our attention. These include the escalating number
of road casualties. This study was conducted to observe road hazard outside the school compound and analyse the
safety risks faced by school children by using the risk matrix. The risks are calculated to include likelihood and
severity of hazard as identified in the Guideline of HIRARC 2008. The area selected was the East Coast state of
Peninsular Malaysia, with over 111 schools randomly selected in Kelantan. Results were then analysed and six
highlighted hazards were discussed. The results show that the main road posed the highest risk due to speeding
vehicles. These vehicles failed to slow down when approaching the school area. The school
administration must enhance the safety of the staff, students, and public while in the school area. In conclusion, road
safety awareness must be instilled among teachers, students, parents and road users alike.
Awareness of occupational noise and its effects is growing. At No. 11 squadron base, Sukhoi jet was identified as the main culprit of occupational noise that affects not just the employees of the base but also civilian people in the surrounding area. The objective of the study is to identify the noise level produced by Sukhoi two-engines jet during maintenance operations. Investigations were carried out using Bruel & Kjaer 2250 sound level meter hand-analyser. Measurements were performed directly under the Sukhoi jet body and then 10 metres, 50 metres, 100 metres, 1000 metres and 1500 metres away. The jet engines could operate at two levels, at 72% RPM and at 85% RPM. The civilians are only exposed to its noise from more than 1000 metres away. The results from this study are analysed and noise mapping and noise contouring are produced which give the level of noise exposure. The maximum noise is recorded t 122dB(A) and the minimum is at 60dB(A). The farther the noise from the jet is measured, the lower the values recorded. From the noise mapping, the effects of noise exposures on both the employees at the base and the civilian at the neighbouring surrounding could be identified. Even though the exposures are only for 5-10 minutes, it is still considered as a threat
Road Safety remainsone the most important issuesaffecting educational institutions especiallythe school. The
prevalence of road accidentsin recent news reportsunderlines the importance of this issue. Such accidents involving
school pupils have further escalated this concern. As such,safety awareness among school teachersis crucial in order
for them to identify the suitable methods to prevent more road accidents in future. This study was conducted to
analyse teachers’ awareness of road safety in school to gauge the training requirementson road safety. Road safety
education and training in school is just as important as improving safety for road users outside schools. For this
study, a set of survey questionnaire wasdistributedto 400 school teachers from 111 schools randomly selected from
the 10 District Education Offices in Kelantan. Results were then analysed using Statistical Package for the Social
Sciences (SPSS). From the results, 40% of respondentswere male and 60% of them were female. Descriptive analysis
showed that school teachers understood road safety as 90% of them possessed basic safety knowledge, while 10% of
them lacked basicknowledge on road safety. However, they did not implement safety practice that may have
contributed to unfortunate eventshappening outside of school including road accidents as reported in the news. This
study suggests that school teachers must undergo road safety training to promote and improve road safety in
school.With higher awareness and more information about the road safety, the teacherscould create a safer
environment in their school. Undoubtedly, teachers have a vital roleto ensure safety of their pupils and their
commitment will likely reduce the number of road accidents.
