Currently accident cost calculations involve lengthy process of data collection procedures. Accident cost
calculations can be categorized into direct and indirect costs. Many manufacturing industries are having difficulties
in identifying and quantifying the accident cost category. Besides, it involves manual data collection which is time
consuming and has high tendency to make errors throughout the process. The data collection process also involves
various parties. For example, getting direct cost data from human resource department while indirect cost data need
to be obtained from manufacturing and safety department. The objective of this study is to propose Web-Based
interactive Accident Cost Calculator (WBACC) for manufacturing industries. This WBACC has two options; option
1: calculations based on input data at the time of accident. Option 2: calculations based on historical data such as
previous accident records. Option 1 is much simpler because it only requires accident demographic data while option
2 is much more complex. However, option 2 is more accurate compared to option 1. This proposed WBACC can be
used by safety and health practitioners to convince their top management in making decisions especially on safety
budget allocation.
Small and Medium Enterprises (SMEs) are known to be one of the major contributors to the national economy.
However, in terms of Occupational Safety and Health (OSH) implementation and performance, these SMEs,
especially in the metalworking sector have yet to meet the necessary standard. This paper discusses the statistical
analysis of accidents in metalworking industry by using accident reports submitted to the Department of Safety and
Health (DOSH) which involved 740 accident cases. The main objective is to identify the real causes of accidents and
recommend an appropriate action plan for accidents prevention at the workplace.
There are several alternative sampling and analytical methods available for the determination of respirable
crystalline silica exposure among workers. The commonly used ones are, (1) NIOSH Manual Analytical Method
No.7500(NMAM 7500) which is Silica, crystalline, by X-ray difractometer via filter deposition(NIOSH 2003), and
(2) MDHS 101 (Methods for the Determination of Hazardous Substances (MDHS) Guidance No.101: Respirable
crystalline silica in respirable airborne dust). The aim of this study is to compare applicability of respirable crystalline
silica sampling and analysis between method MDHS 101 and NMAM 7500. Laboratory procedures will be performed
strictly based on MDHS 101 and NMAM 7500. Both methods apply X-ray diffraction as analytical technique with
many variations on sampling techniques and laboratory preparations. Quality assurance values such as detection
limits, accuracy and precision are derived from both data and will be compared to determine which of the method
establishes better quality assurance. The method which establishes better quality assurance will be recommend to be
used in Malaysian respirable crystalline silica monitoring programme. The strength of this research lies on its potential
to provide local capabilities in analysis of respirable crystalline silica in Malaysian setting.
Legionellosis is a respiratory infection caused by gram-negative bacteria known as Legionella. Although there are
many species of Legionella, the majority of all reported cases of legionellosis were caused by Legionella pneumophila.
Investigations of Legionella outbreaks comprised sampling building water systems for the presence of Legionella.
The aim of this study is to determine the isolation techniques with the most optimal yield for detection of Legionella
based on the Australian/New Zealand Standard Waters –Examination for Legionella (AS/NZS 3896:2008). This is an
experimental research, in which, Legionella species will be spiked in a bottle of water and various isolation techniques
will be conducted. As most cases of Legionellosis are caused by Legionella pneumophila group, this group of species
will be used.
Working in a safe working posture is a necessity to enhance occupational health of industrial workers. Poor
working posture may lead to injuries, discomfort and fatigue to the workers. The objective of this study is to survey the
postures practised by the Malaysian industrial workers. A questionnaire survey was performed among 282 Malaysian
industrial workers in 10 different industries. From the answered questionnaire, it was observed that shoulder at chest
level (30.1%), back in a bent forward (33.3%) and lifting heavy load (44.7%) are the major work postures practised by
most of industrial workers. This survey identifies that working with shoulder and hand at chest level and back region
moderately bent forward is the main working posture practice by worker. Workers also reported lifting load below 5 kg
at the workstation. This survey recommended for industrial workers to be aware of the comfortable working posture
to avoid injury.
This study is carried out to establish the prevalence of Work-related Musculoskeletal Disorders (MSD) among
the Malaysian workforce population in order to propose some measures to benefit the people at large. Secondary data
from three studies among drivers, clerical workers using visual display terminals (VDT) and fabrication workers were
used to report the prevalence of MSDs and the associated risk factors. The study identified high prevalence of MSDs in
multiple body regions. The MSD occurrence was also significantly associated with psychosocial factors. There is need
for organisations to consider such factors in work design, which will reduce the high prevalence and high financial
implications associated with MSDs among workers.
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.
The indoor air contaminations in the buildings are normally contributed by causes from humans, animals and air
borne fungi. These factors greatly cause the problem of sick building syndrome and indoor air pollutant. This study
was undertaken to discover the potential efficiency of biocide potassium sorbate to remediate the indoor air fungal
especially on wood material. Samples of fungal were collected according to NIOSH Method (NMAM 0800). The total
amount of fungi and bacteria were enumerated at 806 cfu/m3 and 280 cfu/m3, respectively in a lecturer’s room. The
study also revealed that the growth of fungi was at the minimum when incorporated with a biocide treatment according
to ASTM D559000 standard. This biocide has been proven to be effective and able to reduce the growth rate of indoor
fungi. Overall results showed that this type of biocide is effective to overcome the fungal problem on wood material
in the buildings.
The trends of safety incident process have been put in the statistical research and development in order to prevent
and mitigate the phenomenon. One of the incidents is known as dust explosion. It represents a constant hazard to
industries which includes any manufacturing using and handling combustible dust materials. Lack of sharing and
know-how on best practices in managing the workplace must be avoided throughout the industries. The severity and
the consequences of not taking the safety precautions at workplace have not been foreseen by the process team. This
present paper discusses the best practices in managing the hazards from the catastrophes to happen again. In addition,
the mitigation response has also been explored thoroughly through database of best practices.

Automobile exhaust emission control is one of the trending issues in automobile research field. It caused by high
pollution such as carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons (HC) distributed by automobile
especially form diesel engine. These pollutants give a harmful effect to the environment and human health. Therefore,
this paper proposed in reviewing methods on fabrication of modified catalytic converter. FeCrAl is used as substrate
which treated using ultrasonic bath technique which could improve the exhaust emission control. This metallic catalytic converter used as the replacement of precious metal that have high production cost.
Pesticides are commonly used for pest control in oil palm
plantations. The knowledge, attitude and practices (KAP) while handling pesticides
may potentially result in adverse health effects among the estate workers. The aim of
this study is to determine the KAP of pesticides used and the capacity of selfreporting
health conditions among workers in palm oil plantations. A crosssectional
study was conducted to investigate the KAP and its self-reporting health
symptoms by using questionnaires and face-to-face interviews to 120 male estate
workers who use pesticides in their daily work routine in the oil palm plantation. At
least 85.8% of respondents had a good knowledge of pesticide used, 46.7% of them
indicated neutral level of attitude on the pesticides’ usage, and 68.3% of them
demonstrated a good practice while handling mixture of pesticides. Overall, there is
a significant association between the practices of pesticide usage with the selfreporting
health symptoms, such as dizziness, excessive vision, cough,
nausea/vomiting, redness of skin, difficulty in breathing, skin rashes, blurred vision,
excessive sweating and hand tremor. More than half of the estate workers indicated
a moderate to good knowledge, attitude and practices level of pesticide handling in
oil palm plantations. This study suggests that the self-reporting symptoms are real
and not over-reporting by workers. The increase in KAP of pesticides usage among
these workers have highlighted the necessity to improve the traditional field training
method of safe handling of pesticide to a sustainable field practical-based learning.
The latter training approach is to engage theory into practice.
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.
Safety behaviour is important in preventing industrial accident.
Safety leadership attribute by the supervisors is one of the determinants of safety
behaviour among the employees. This study aimed to determine the influence of
employer’s safety leadership towards worker’s safety behaviour within Small and
Medium Enterprises (SME)-Manufacturing in Negeri Sembilan. Three independent
variables representing safety leadership namely safety motivation, safety concern
and safety policy were selected whilst safety compliance and safety participation
were the dimensions used to measure safety behaviour. Self-administered
questionnaire were distributed and answered by 210 employees of Negeri
Sembilan’s SME-Manufacturing. The results revealed that safety concern and safety
policy had significantly influenced safety compliance. Whilst, safety motivation and
safety concern determined the workers’ safety participation. No significant influence
found by safety motivation towards safety compliance as well as safety policy
towards safety participation. Safety concern was the important component of safety
leadership as it consistently explained the variance in all dimensions of safety
behaviour.
