Ergonomics can be viewed as an approach to reduce injury and illness rates to improve the overall working
conditions for employees by addressing risk factor exposure that may occur during manual tasks. The objective
of this research was to analyze ergonomics risk factors by associating the perception of employer and employees
towards their workplace condition in quarry and mining industry. A Questionnaire on Ergonomics Risk Assessment
was used to determine the comparison level awareness and perception analysis among quarry and mining industry in
Malaysia. The findings of this research prove that the exposure of ergonomics risk factors towards the workers is in
a moderate level with a mean of 3.59 for the overall respondent review about the ergonomics risk among workers at
their workplace. Besides, the most concern in ergonomics is about the awkward posture at work. Some 8.8% of them
agreed and 6.6% of them totally agreed that they were in awkward posture while doing their work. As a conclusion,
assessment of ergonomics in quarry and mining industry will be a platform to provide a safe and healthy working
environment.
The frequency of occupational accident in small medium industries decreased from 2008 in general, but fluctuated each year,
which shows that improvement is needed in handling safety and health of the employees. It is believed that safety climate perception
and occupational safety health management system (OSHMS) influence occupational accident in an organization. A safety audit
checklist and self-administered questionnaire was distributed to the involved small medium industries. The findings show that safety
climate perception was high in small medium industries while OSHMS show low compliance. Findings also showed that there were
significant relationships between safety climate perception and OSHMS with occupational accident in the organizations (p
This study has been conducted in a new constructed building of NIOSH Malaysia located at Bandar Baru Bangi, Selangor. The goal of the case study is focusing on the level of Indoor Air Contaminants (IAC) including chemical contaminants within three consequent stages which are before furniture install, after furniture install and during one month occupancy. This study was divided the sampling area into two main facilities which are training and office setting. The contaminants has been measured consist of sixparameters such as Carbon Dioxide (CO2), Carbon Monoxide (CO), Total Volatile Organic Compounds (TVOC), Formaldehyde, Respirable Particulates (PM10) and Ozone. The result of Carbon Monoxide (CO), Total Volatile Organic Compound (TVOC), Respirable Particulates (PM10) and Ozone show an increasing trend across the three sampling stages. The Formaldehyde show an increasing trend in the first and second stages but were reduced significantly the last stage of sampling. These finding indicates that furniture and fittings installed might be a potential sources of indoor air contaminants. The management should be aware to their indoor air status to protect the occupant from the risk of unwanted exposure especially during the early stage of building occupancy.
A preliminary study has been conducted in a new constructed 8 stories building (2 level of Hostels facility, 3 level of Training Room, 2 Level of Offices and 1 level of Exhibition Halls and Rooms) in Bandar Baru Bangi, Selangor. The Hostels facility is a floor tile and furnished with build in locker and use split air conditioning system while the Training Room and Exhibition Rooms used floor tile. The Offices and Exhibition Hall are carpeted furnished. All these spaces were using centralized air conditioning systems. A pre-commissioning assessment on 5 chemical parameters of indoor air pollutants such Total Volatile Organic Compounds (TVOC), Formaldehyde, Respirable Particulates (PM!
This paper is focusing on developing theoretical model on the effects of psychosocial and physical safety climate
towards workers task performance. Psychosocial and physical safety climate can be defined as workers’ perception
on organizational policies, process, and procedures outline, specifically on psychosocial issues and physical safety
aspect. This paper is based on sociotechnical philosophy by highlighting the integration of both psychosocial and
physical safety climate in predicting task performance. According to the philosophy, workers working performance is
dependent on both social and technical context in environment to accomplish the task and will influence both physical
products and psychosocial outcomes. Thus, it is essential to investigate the integration of psychosocial and physical
safety climate in predicting performance outcome.
Engineering control is a method of controlling the risk of exposure to contaminants. Health effects to industrial workers are more severe whilst high exposure and time exposed to contaminants at workplace. Installation of industrial ventilation or local exhaust ventilation (LEV) system is the proposed method to reduce the risk. This paper discusses the past, present and future relating to LEV system in Malaysia. Current issues related to monitoring reported by Hygiene Technician in compliance with Occupational Safety and Health (Use of Standard Chemical Hazardous to Health Regulation 2000) carried out in several states in Malaysia as a sample. The nanotechnology is a new area at present and future. The involvement of government, employers and employees need to be justified due to the attention to prevent and control of any exposure. It is suggested that using the Computational Fluid Dynamic (CFD) simulation, a new design of LEV system can be upgraded and predicted.
The paper focused on the examination and testing of local exhaust ventilation (LEV) systems at one of Electrical Company to check the transport velocity whether it meet the recommended American Governmental Industrial Hygienist (ACGIH) Standard. The industrial hygiene approaches, AREC (Anticipating, Recognize, Evaluate and Control) were adopted in this study. This is to ensure that the LEV system installed has the optimum efficiency to extract out the contaminants from the workstation. Objective of this study is to make comparison with previous and current monitoring data. The efficiency and the other parameter measured will be the main source to analyze for the particular applications. The differential of data was discussed and several recommendations are proposed to make sure the LEV system performance is excellent.
Stress reduces the performance and productivity of employees.
One of the most important stressors originate from organizational factors,
which are decision latitude, psychological demand, social support and job
insecurity. This creates four kinds of jobs: passive, active, low strain and high
strain. The objective of the study is to determine the association between
organizational factors with occupational stress and cortisol level among
lecturers in University Selangor. This cross-sectional study used a purposive
sampling, which involved 45 lecturers from various faculties. The instrument
used in this study was Job Content Questionnaire (JCQ) which is a
Psychosocial Job Assessment Instrument designed by Karasek et al., (1998).
The questionnaire has been translated to Malay version by Edimansyah et al.,
(2006). 10ml of blood sample was collected from each respondent by certified
phlebotomist. Results from the statistical analysis showed that majority of the
respondents were female (75.6%), aged below forty years old (82.2%), married
(77.8%) and hold a master degree (68.9%). Most of the respondents were
found having low decision latitude 35(77.5%). Majority of the respondents
were also found in passive group 13(28.9%) which were having low
psychological job demand and low decision latitude, while others are in low
strain 11(24.4%), high strain 11(24.4%) and active group 10(22.2%)
respectively. There was a significant association between two organizational
factors with occupational stress level, which are decision latitude and
psychological job demand (p0.05). As a
conclusion, two out of four organizational factors, which are decision latitude
and psychological job demand showed a significant association with
occupational stress levels. Cortisol as one of stress biomarkers may not be
significant due to small sample size.
This study aims to determine the awareness level of safety
management and safety behavior among SMEs workers. Safety management as a
subsystem in the overall management of the organization. It is designed to control
hazards that can affect the safety and health of workers. Small and Medium Enterprise
(SMEs) in Malaysia continue to face many challenges both traditionally and new.
80% to 90% of occupational accidents occurred involving worker of SMEs industry.
A self-administered questionnaire was distributed to the involved small medium
industries. Questionnaires form that consist of three sections, namely socio
demographic, safety management and safety behavior. This study was conducted at
selected SMEs located in Klang Valley. 226 workers responded. In order to interpret
the level of awareness among the respondents, a 3-level scale (High: 3.68 – 5.00,
Moderate: 2.34 – 3.67, Low: 1.00 – 2.33) based on the mean score was used suggested
by Ashari & Mahmood. The findings show that the highest level of awareness was
safety behavior while the lowest awareness level was safety promotion policy
respectively. Findings also showed that, there were moderate correlation between
safety management and safety behavior. Understanding the concept of the OSH
management system will help us to understand the application of OSH management
system in Malaysia. OSH Management very important to prevent accident, ill health
& injury at workplace towards development of safety culture.
Today, more accidents reported in school, resulting not only minor injuries but also severe injuries such as fire in schools, mercury spills and falling from high places. The study was aimed at measuring the level of occupational safety and health practices in schools. The study was conducted at 205 schools in Kelantan, Malaysia. This study is a semi-quantitative study using observation method. Data collection is conducted based on Hazard Identification, Risk Assessment and Risk Control (HIRARC) Guidelines provided by the Department of Occupational Safety and Health, Malaysia. Hazard identification, risk assessment and risk control are determined using the HIRARC form. The findings were measured by determining the discrete data according to the number of low, medium and high-risk levels found. The study found that there were two dominant hazards namely physical hazard and ergonomic hazard. Therefore, the management should increase and improve classroom safety awareness to ensure safety and health of all occupants.
Local exhaust ventilation (LEV) is used in industries to capture contaminants such as gases, dusts, mists, vapours or fumes out of workstations to protect occupants’ exposure to contaminants. LEV is allocated and installed by employers, however it doesn’t work accordingly. LEV design is often overlooked and underappreciated. Effectiveness of LEV system can be achieved if more attention is focused to proper design of LEV system. To solve this issue, computational fluid dynamics (CFD) can be performed. CFD is a software tool to predict and simulate fluid dynamic phenomena. CFD is used to forecast or reconstruct the behaviour of an engineering product under assumed or measure boundary conditions. However, CFD is just a prediction tool, which can lead to inaccuracy of predicting airflow due to problems with pre-processing, solver and post-processing with parameter from actual experimental results. Therefore, validation is needed to help minimizing percentage error of CFD methods. In this research, measurements of airflow parameter of LEV system at National Institute of Occupational Safety and Health (NIOSH) Bangi, Selangor were conducted. Control Speed panel found at NIOSH Bangi, which is used to increase or decrease speed of fan, was performed using Control Speed of 20%, 40% 60% and 80%. Upon validation, average absolute error obtained from four different control speeds ranges from 3.372% to 4.862%. Validity of CFD modelling is acceptable, which is less than 5% and good agreement is achieved between actual experimental results and CFD simulation results. Therefore, it can be concluded that CFD software tool can be performed to simulate air velocity in LEV system. CFD methods can save labour costs and time consumption when it is used during earliest stage of LEV design, before actual construction is implemented. The outcome of this paper can be used as a baseline for factories equipped with LEV system to protect occupants’ exposure to contaminants.
In the recent years, an extensive number of scientific researches on occupational diseases have been done to
identify occupations at high risk of inducing diseases. There are many categories of occupational diseases, and unitary
of them are occupational respiratory diseases. This study was conducted in a tea factory located in Cameron Highlands,
Malaysia, with an output of 600,000.00 kg per annum. Its objective was to evaluate respiratory diseases among the
workers, conducted via questionnaires, interviews and lung functional tests. A total of 38 workers participated in this
study, 19 in the exposed group and 19 in the control group. The most common chronic symptoms for the exposed
group are wheezing, dyspnea (short of breath) and phlegm. The result shows that, among the tea processing workers,
the exposed group suffer from respiratory diseases.
Introduction: This study explores the health status of injured workers in return to work (RTW) programs based on their ability and capacity. Injured workers were diagnosed with work-related musculoskeletal disorders. The findings will help not only the service provider plan a specific strategy but also allow stakeholders to review their role in the RTW program.
Methods: 102 participants were chosen from a national RTW program, and categorized into three groups based on different phases of the RTW program: off-work (n=30, 29.4%), work re-entry (n=44, 43.1%) and maintenance (n=28, 27.5%). Self-report questionnaires identified demographic data, health surveillance via SF-36 and perceived physical and psychological workload by 10-point numerical scales. Analysis of variance (ANOVA) and Kruskal-Wallis Test was employed to examine the differences in three phases of the RTW program. Paired t-test analyzed the differences of related samples of physical and psychological workload before and after injuries.
Results: The domains of health status are below the average compared to the norm-based population. Mental health component summary is better than physical health. At the domain level, there are significant differences among injured workers, specifically in the three RTW program phases. The SF-36 domains are: role-physical, vitality, bodily-pain, general health, and mental health (p ! 0.049). In contrast, non-significant differences were found in physical and social functioning, and role of emotion status. Moreover, their self-perceived physical and psychological work-load significantly worsened after injuries (p ! 0.020).
Conclusions: The case manager-coordinated RTW program provided further opportunities to improve injured workers’ health status when looking at their differences for different phases of RTW. Other health professionals like occupational therapists, ergonomists and psychologists should become involved in the RTW program. Specific guidelines and regulations have to be implemented to ensure full participation with all parties in the workplace.
The effects of propylene stored in pressurized spherical vessel were investigated using radiation & explosion modeling using PHAST 6.7 software in one of the refinery in Malaysia. The simulations were performed for various weather conditions with different leak scenarios in deterministic approach. Modeling approach was standard with current industry practice. Resulting events such as jet fire, vapor cloud explosion, boiling liquid evaporating vapor explosion effects shown in thermal radiation and overpressure towards targeted technical buildings. The effects of resulting jet fire flame length increase with release rate and explosion overpressure effects increase with degree of confinement and volume fraction respectively. The results were reviewed, interpreted against industry standard. The sensitivity cases show that, using lower inventory with moderate operating conditions will keep the consequence in acceptable region. This consequence analysis will form a basis for layout development, safety distance and fire zone segregation during conceptual design stage. Propylene storage conditions, layout arrangements and blast protections were recommended as part of preventive and mitigative measures.
This study illustrates about the most hazardous and risky activities associated with well drilling operation at on and offshore
oil and gas drilling sites by adopting exploratory research design (quantitative leading to qualitative). In this study researcher has
targeted three oil and gas industries each from Malaysia, Saudi Arabia and Pakistan for the identification of associated hazards
and nature of hazardous activities faced by drilling crew during well drilling operation. Eighty (80) drilling crew members have
been randomly selected for answering the survey questionnaire. Likewise, nine (09) drilling health and safety officials have been
conveniently selected based on their safety expertise in oil and gas drilling field for semi structured in-depth interview. For analyzing
quantitative findings descriptive statistical methods has been used. While for qualitative section thematic analysis approach has
been utilized. Based on the findings, respondents from Malaysian oil and gas industries reported starting drilling activity as highly
hazardous at onshore well drilling, while handling drilling pipe has been considered more hazardous activity at offshore domain.
Similarly, in the context of Saudi Arabia, respondents highlighted that the handling drilling pipes are cause of major injuries at onshore
well drilling site. Whereas drilling fluid preparation and coring process is considered harmful at offshore sites. In contrast, participant
from Pakistan indicated coring process as a highly hazardous activity at on and offshore well drilling operation. According to overall
results based on the participant response, oil and gas well drilling operation at onshore domain is considered more hazardous
at Pakistani oil and gas industry as compare to other targeted industries with mean range 3.42. While for offshore well drilling,
Malaysian industry is recorded highly hazardous as compare to others leading with mean value 3.39 and related with chemical and
safety hazards in well drilling activities.
Occupational safety and health (OSH) in Small and Medium Enterprises (SMEs) have not received the proper
attention not only in Malaysia, but also in most countries all over the world, in terms of research or support for
implementation. In Malaysia, many agencies such as the Department of Occupational Safety and Health (DOSH),
Social Safety Organization (SOCSO), National Institute of Occupational Safety and Health (NIOSH) and many more
agencies related to OSH have been in collaborations to conduct and promote a safety working environment and to
protect human rights economically, morally and legally. This research mainly focuses on the implementation of the
occupational safety and health in small and medium industries in the southern region of peninsular of Malaysia. This
exploratory study will be based on conducting a survey to 500 SMEs owners and workers throughout the southern
region of Malaysia to get the in-depth knowledge on how the implementation of safety and health management system
in the SMEs will affect them both morally and economically. A site visit will also be conducted in order to enhance
and to get to know the real situation happening in the real working environment. The results of this study will be used
to make and initial evaluation of the implementations of OSH management system in SMEs and hopefully will help
for future interventions and researches.
Occupational safety and health (OSH) in Small and Medium Enterprises (SMEs) have not received the proper
attention not only in Malaysia, but in most of the countries globally, in terms of research or support for implementation.
This research focuses on the implementation of the occupational safety and health in small and medium industries in

area.
Pemprosesan padi adalah salah satu daripada sektor pertanian yang terbesar di Malaysia. Kekerapan kemalangan
di tempat kerja yang berlaku dalam sektor ini berpunca daripada pelbagai faktor. Antara faktor utama ialah tahap
pengetahuan dan kemahiran tentang keselamatan dan kesihatan pekerjaan (KKP) yang rendah. Objektif kajian
ini adalah untuk menilai tahap pengetahuan KKP dan hubung kait antara tahap pengetahuan dan amalan pekerja
berkaitan KKP dalam sektor ini. Seramai 300 orang responden yang terdiri daripada petani dan pemilik sawah padi
di Sungai Besar, Selangor dipilih untuk menyertai kajian ini. Penyelidik menggunakan pendekatan soal selidik dalam
mengumpulkan data kajian. Nilai Cronbach Alpha didapati daripada ujian kebolehpercayaan menggunakan perisian
SPSS 20.0. Hasil kajian nenunjukkan bahawa jumlah responden tertinggi adalah seramai 138 orang yang bertugas
membaja dan meracun. Selain itu, seramai 254 responden mengetahui cara bekerja dengan betul dan selamat. Manakala,
seramai 242 responden mengetahui bahawa bahan kimia boleh meresap ke dalam kulit, mulut, sistem pernafasan dan
seterusnya mata. Hasil kajian mendapati responden yang terlibat mempunyai tahap pengetahuan memuaskan tentang
pendedahan risiko fizikal dan pendedahan risiko kimia terhadap tubuh badan mereka serta peralatan perlindungan
diri yang diperlukan. Walau bagaimanapun, terdapat segelintir responden yang tidak peka untuk meletakkan amaran

A study has been conducted on trans,trans-muconic acid (t,t-MA) as the biomarker for benzene exposure among
oil and gas petrol tanker drivers. The objectives of this study are to determine the significant difference and the
correlation between Benzene personal exposure and urinary t,t-MA among exposed and non-exposed workers. A total
of 92 questionnaires were distributed to obtain demographic and descriptive data. Benzene personal exposure was
sampled using SKC passive samplers and the data was analyzed using GC-FID. Urinary t,t-MA was collected at end of
work shift and analyzed using HPLC-UV detector. A total of 30 non-exposed workers were also sampled. The averages
of urinary t,t-MA were 96.65 ug/g creatinine for exposed workers and 0.51 ug/g creatinine for non-exposed workers.
Meanwhile, the averages of Benzene personal exposure were 0.37 mg/m3 and 0.01 mg/m3 for exposed workers and
non-exposed workers respectively. No significant correlation was found between exposure to benzene with excreted
urinary t,t-MA of workers occupationally exposed (p-value > 0.05) as well as to workers non-exposed to benzene
(p-value > 0.05). In conclusion, there is no significant correlation found between Benzene personal exposure and
urinary t,t-MA among exposed and non-exposed workers. Applicability of using t,t-MA as the biomarker of benzene
exposure shall be further discussed with all the other confounding factors to be taken into account.
Recent statistics from the Social Security Organization (SOCSO) of Malaysia shows Commuting Accident (CA)
increased consistently by 1500 cases per year from 2008 to 2012. This has resulted in the rising of fatality rate,
extensive claims of compensation payment and not to mention loss of valuable talents. However, little is known
about the contributing factors to the occurrences of CA in Malaysia because CA is never considered to be work
related before. This study aims to explore work related factors with occurrence of CA using 5-year statistical data
from SOCSO, Malaysia. Moreover, we also reviewed studies published between 1990s and 2014 to support the
statistical findings. Motorbike is found as the most common vehicle used which involved in CA. Individual factors
concerning workers behaviour is a main risk factor of CA. Family related factors (parenting responsibility), work
burden, workplace support as well as environmental factors such as bad weather and bad road conditions are also
significant contributions of CA. It is very important to develop behavioural intervention strategies and provide proper
training. Hence, more attention should be directed to young individual workers in balancing them with capabilities and
organization performance demand. This may lead to the elimination of the other causes of CA. In conclusion, solutions
to this problem involve not only a particular party to ensure the wellbeing of workers in Malaysia, but all authorities
should play roles in enhancing safety and health matter of workers especially on the occurrence of accident.
