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.
In this research, the biodiesel from WCO is used in order to reduce the exhaust emission and to investigate the
community perception regarding to the human health. Biodiesel production is conducted using trans-esterification
process with holding time of 2 hours, temperature of 60 oC and conventional frequency of 20 kHz and then followed
by washing process with holding time of 1 hours, temperature of 50 oC and the frequency of 5 kHz. Biodiesel can
reduce exhaust emission of NOx up to 55%, NO gas up to 57%, increase CO gas up to 25% and increase CO2 gas up
to 43.18% as compared to diesel fuel. In addition, biodiesel is achieve good responds from 35 respondents about the
biodiesel importance.
The energy price increased significantly since the early 1970’s and it shows the pattern of all over the world.
According to the estimation of International Energy Agency (IEA), 53% global energy consumption will be increased
by 2030, with 70% of the growth in demand coming from developing countries. Malaysia is one of the most developing
countries among ASEAN countries next to Singapore, with GDP of US$15,400 per capita (PPP basis), and steady
GDP growth of 4.6% in 2009. Malaysia as a developing country focuses on the energy efficiency approach. At this
moment a lot of number of fire and electrical incident more towards overload current and the issues has been faced
trough out the year. This paper highlight the issue on how to avoid the overload current by introducing the method
establish by Energy Commission. The star (*) rating will help us to estimate the current use and the energy efficiency
approach by calculate the current load. The data collected from home appliances are the very basic information rather
than predict in a large scale as industrial and commercial building since the tariff also different in the category. The
equipment such as amp meter, volt meter and the current load data logger will help the current consumption in every
home appliances and it will show the direct reading as well. The issue on electrical safety should be response by
consumer to prevent safety and health risk.
The objective of this research is to analyze and evaluate the hand arm vibration exposure of hand held grass
cutter machines during their normal operation time. On-site field measurement for five different types of hand held
grass cutter machines. In this research, the hand arm vibration exposure levels of different machines were measured
at practical cutting condition in accordance to guidelines on occupational vibration which are presented in the
occupational safety and health standard manual. The hand arm vibration level on the worker’s both right and left
handles of the grass cutter machine were measured and analyzed, respectively. The vibration frequency weighting
acceleration was calculated by using h-weighting. The hand arm vibration acceleration value was expressed in the
root-mean-square (rms) combination of all three major axis (ahwx, ahwy & ahwz). The estimated daily vibration exposure,
A(8) were differ between 2.1 to 20.7 ms-2 for right hand while 2.7 to 29.1 ms -2 for left hand. In short, worker will
induce fingers blanching in 10% of the exposed person after less than 3.7 years exposed to hand arm vibration.
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.
Indoor air pollution is rapidly becoming a major health issue worldwide. The quality of indoor air inside building
is important not only for occupants’ comfort but also for their health. Although researches are still under way to
better define the nature and extent of the health implications for the general population, recent studies have shown
significant amounts of harmful pollutants in the indoor environment. Poor indoor air quality (IAQ) has been tied to
symptoms like headaches, fatigue, trouble concentrating and irritation of the eyes, nose, throat and lungs. In this study,
occupants’ comfort satisfaction on IAQ of a museum building environment in a tropical climate will be studied. IAQ
aspects which will be considered as parameters are chemical contaminants, gaseous pollutant and comfort factors
(temperature, humidity and air movement). Museum, archives, library, heritage building and gallery are the types of
buildings that can be considered as heritage building environment. At the initial stage, a pilot study will be conducted
to identify the current IAQ conditions inside those selected buildings.
Indoor Air Quality (IAQ) is a subset of Indoor Environmental Quality (IEQ), where IAQ is about what we
breath. Poor indoor air quality (IAQ) can cause health problems to the residents. Air conditions in the shelter must
be preserved, in order to ensure the safety and health of the residents. Certain indoor plants can filter out toxin found
in the air. Other than that, indoor plants can help clean the air. In this study, seven types of indoor plants that can live
in equatorial climate like Malaysian environment will be selected. At the initial stage, planting of all types of indoor
plants will be done, from sowing seed until all plants grow up. In the next stage, all plants will be tested to determine
their effectiveness to improve indoor air quality. The comparison of data before and after installation of indoor plants
is made. To gain the benefits of indoor plants, detailed study should be done in terms of response and monitoring of
indoor air. The reason of this study is to provide benefits to building occupants. Besides, having the interior plants as
part of decoration items may improve workers’ productivity and reduce stress.

Indoor air quality has been a major public concern recently. Several health effects are related to this problem.
Findings from several studies have shown MVAC system as the main contributor for IAQ problem. Good practice of
maintenance and servicing is important to maintain MVAC system, especially the filter. Good air filtration for MVAC
system is needed to make sure adequate air is received by the occupants. This paper illustrated a recent study of air
filtration for MVAC system especially for several industries that used MVAC system in their premises. This paper also
proposed an air filtration study for a better air quality. Several Acts and Regulations related to Safety and Health were
identified to create the framework for the proposed study. Air filtration technique was used in this preliminary study
to set up guidelines to create safe and clean indoor spaces for workers and occupants.
Evacuation profile systems in high rise building are important to determine the safety level during any fire
emergency. In relation to this, the study was conducted with its objective to develop the evacuation profile for
NIOSH Tower. Evacnet-4 software was used to develop models for building evacuations using the building network
descriptions and the initial content of the occupant at the beginning of the evacuation. The results show that it
requires 390 seconds to evacuate NIOSH tower, with the highest number of bottlenecks recorded for the Third Floor.
Identification of bottleneck is important to determine the evacuation periods. The information gained from the model
may be used for the emergency response planning and for support material. The model should be tested in real time
to have its reliability verified.
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.
Lack of safety awareness among quarry workers caused a number of accidents in quarry industries. The objective
of this study is to gauge the awareness level towards safety among quarry workers. A questionnaire was distributed
randomly among quarry workers in Pahang, Terengganu and Kelantan. The questionnaire consists of 6 questions
regarding safety at workplace. Results revealed that 56.9% of the respondents agreed and totally agreed for the health
and safety suggestions made to be given consideration and used. As many as 79.3% respondents admitted that they
obeyed all the safety rules stated at the workplace and 86.3% respondents said that they always focused and gave
full attention while completing their task. A high percentage of 88% of the respondents agreed for all accidents
to be reported to responsible persons while 77.6% respondents agreed for all personal protective equipment to be
used suitable with the task given and 86.2% respondents answered that they performed their task following the safe
operation procedures provided by the company.
Unsafe behaviour is the key factor which contributes to the high number of incidents. Applying Behavior-Based
Safety (BBS) into safety risk controls has been adopted in major industry toward improving safety performance.
This approach to prevent incident has a number of advantages. The objective of this study is to identify the BBS
factors which can contribute to reduce incidents at the workplace. Human factors, behaviour and environment have
been identified as BBS factors. Human factors are influenced by knowledge and understanding of the workers while
behaviour factors are influenced by culture and practices in a daily life. In addition, environmental factor involves
equipment and work area. For an effective BBS approach, level of knowledge, understanding and practices by the
workers become the main concerns in the implementation of BBS. The findings can become the reference model for
future implementation in other organizations and as a guidance for better safety management.
This objective of the study is to estimate occupational accident cost in manufacturing industries, especially in
wood based related industries. The study attempts to identify, define, and classify the cost components of occupational
accident related cost and to catalogue the various economic approaches used to estimate the entire costs of occupational
accident and to propose the risk prevention plan. The study uses local specific approach by reviewing company
historical records on occupational accident as reported in JKKP 6, JKKP 8, JKKP 9 and company internal investigation
reports. For each occupational accident, the site safety officer in charge, human resource and, account employee,
supervisor, victim, related co-workers and relatives were interviewed in order to estimate direct costs, indirect costs,
prevention costs and other personal cost related to the accident. Other related information such as personal data of the
victim, type of injuries, location of injuries and cause of injuries were recorded. A total of 24 occupational accidents
data for the past five years were analyzed in the cost of accident summary report to determine the overall ratio of direct
to indirect cost and ratio of total cost of accident to prevention cost. A further analysis was carried out to determine
the most significant cost of accident related to demographic profiles for Malaysian and Non Malaysian employees. In
conclusion, this study has determined the ratio of direct to indirect cost of occupational accident and has proposed the
risk prevention plan with additional information on cost of accident and cost of prevention.
Medium penyampaian maklumat merupakan media pengajaran utama yang digunakan dalam menyampaikan
maklumat kepada pekerja tempatan dan juga asing dalam Kursus Induksi Keselamatan dan Kesihatan (KIKK).
Justeru, kertas kerja ini menumpukan kepada perbincangan mengenai permasalahan serta hasil kajian lepas berkaitan
penggunaan media penyampaian maklumat sedia ada oleh pekerja asing dalam KIKK. Kesimpulan hasil kajian
perpustakaan mendapati terdapat beberapa masalah penggunaan media penyampaian maklumat sedia ada ini daripada
aspek penggunaan bahasa, cara penyampaian dan medium penyampaian. Bahasa Melayu lazimnya digunakan sebagai
bahasa pengantar semasa penyampaian maklumat dalam KIKK sama ada dalam bentuk teks mahupun penyampaian
lisan. Namun, penggunaan Bahasa Melayu ini didapati tidak difahami oleh kebanyakan pekerja asing terutamanya
pekerja asing bukan warga Indonesia. Cara penyampaian maklumat juga dilihat bersifat satu hala dan kurang difahami
serta medium penyampaian yang digunakan kurang interaktif dan berbentuk presentasi. Malah, medium penyampaian
maklumat seperti PowerPoint yang digunakan masih belum cukup kemas untuk memenuhi keperluan kerja pekerja
asing di tapak bina yang mana teks bahasa Melayu terlalu panjang digunakan, susunan teks dan grafik tidak kemas,
saiz teks tidak konsisten serta penggunaan grafik yang kurang jelas.
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.
Indoor air quality is a term which refers to the air quality in and around buildings and structures, in which it
is related to the health and comfort of those who are in the building. The study aims to identify the relationship
between environmental factors with microbe growth by investigating the concentration of airborne bacteria and
fungi at National Institute of Occupational Safety and Health (NIOSH) and to determine whether indoor bacteria and
fungi concentration were associated with environmental factors such as temperature relative humidity and carbon
dioxide concentration. This research was conducted concurrently with indoor air quality sampling as per requirement
under the Malaysian Code of Practice of Indoor Air Quality (COP IAQ). The COP IAQ requires minimum of one
sample to be taken from each area. If an area consists of a few separated rooms, each room is sampled and measured
independently. Also this approach was used to determine whether there is a difference of indoor bacteria and fungi
in different microenvironments. Results show that there is a significant correlation between humidity and bacteria
concentration and fungi concentration; and between temperature and bacteria concentration. However, there is no
significant correlation between temperature and fungi concentration. This study has also established significant
difference on bacteria concentration and fungi concentration between microenvironments.
According to annual reports from the Social Security Organization (SOCSO), between years 2009 and 2011,
metal industry has the highest reported number of accidents compared to the other manufacturing industry in small
and medium enterprises (SMEs). Therefore, the aim of this study was to investigate the actual causes of problems that
lead to the accidents involving metal industries within SMEs. In this study, a checklist through site visits was used to
collect the data. The overall results revealed that the main causes of accidents are; organization failure, human factor,
machine failure and surrounding environments.
The accident rate in metalworking industries does show a slight reduction over the years. However, it is still so
much higher compared to those of the other industries. Despite the various incentives provided by the government of
Malaysia to improve this situation, the problems still remain. Therefore, this paper aims to investigate the commitment
and implementation of occupational safety and health (OSH) aspect in the metal working industries. A survey was
carried out by posting a total of 550 questionnaires to metal manufacturing companies throughout Malaysia. As
many as 131 questionnaires were returned and a statistical analysis was done. Results of the analysis show that the
employers’ commitment for safety operations is high but the implementation of OSH programmes is poor due to lack
of resources and OSH knowledge.
Pemprosesan padi adalah salah satu daripada sektor pertanian yang terbesar di Malaysia. Kekerapan kemalangan
