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.
Fire emergencies are threat to the occupants of a residential college. Some of the Malaysian residential colleges were built in the 1970s. Back then, the compliancy to Uniform Building By-law 1984 was not entirely practiced. This study aims to evaluate fire safety measures in selected residential colleges of a Malaysian University, which were built before 1984. This includes occupants’ level of awareness and knowledge of the occupants regarding fire safety measures. This study was conducted in selected residential colleges, built before 1984, which were named as A, B, C, and D Colleges. One new college building was selected to be the control variable, the E College. Survey questionnaires were given to 401 respondents to obtain information regarding the fire safety awareness and knowledge. Fire safety inspections were conducted to determine the level of fire safety protection systems in colleges and the documentation of emergency response plan were reviewed. From the study, the level of fire safety awareness among the occupants were higher compared to their fire safety knowledge. Fire safety inspection result indicated that overall buildings inspected complies with the local regulation while safety documentation reviews were satisfactorily adequate. Overall, the score for fire safety measures in all selected colleges were sufficient and in good condition. This study is significant for those in the field of safety and health practice pertaining to fire safety engineering and regulations, to plan for better and more efficient fire hazard and risk assessment.
Work shift has been shown to correlate with accident rates. Understanding of such correlation is pertinent especially among emergency response personnel since the decisions that they make determines not only the outcome of their responses but also the risks of accidents to themselves. A questionnaire data derived study used together with a semi quantitative risk analysis method was adopted to estimate the levels of accident risks between firefighters working on two work shifts. Two hundred and forty eight Malaysia’s Fire and Rescue Department firemen from 24 fire stations working on shifts were selected as respondents. The accident rate among firefighters in year 2006 was 52.8 %. Results showed that the Accident Risk Index (ARI) among firefighters working the 24 hours shift was higher (ARI = 3.14) compared with those in the 12 hours shift (ARI = 2.98). However, there were no significant difference in overall severity of the accidents between the two shifts (p>0.05). The difference in risk levels was attributed to the difference in the likelihood of accident occurrence.
The main objective of this study is to determine the association between respirable hexavalent chromium compounds with urinary β2-microglobulin levels among welders in an automotive components manufacturing plant. 49 welders and 39 workers involved in stamping process were selected as the exposed and the comparative group. β2-microglobulin is a protein renal tubular dysfunction marker that can indicate renal dysfunction caused by heavy metal. Air samples of worker’s breathing zone were collected using personal air sampling pump and filter papers. Filter papers were then diluted and analysed with Atomic Absorption Spectrophotometry (AAS). Workers’ urine samples were collected at the end of 8-hour work shift and analysed with β2-microglobulin ELISA Kit (IBL-Hamburg) and a microtiter reader. Meanwhile, creatinine levels were analysed with creatinine test strips and Reflotron®. A mean concentration of respirable hexavalent chromium compounds in air for the exposed group was 0.135 ± 0.043μg/m3 while for the non-exposed group was 0.124 ± 0.029μg/m3. The mean level of urinary β2-microglobulin per creatinine for the exposed group was 84.996 ± 39.246μg/g while that of the comparative group was 61.365 ± 21.609μg/g. The concentrations of respirable hexavalent chromium compounds were higher in the exposed group compared to the comparative group (Z=-2.444, p=0.015). β2-microglobulin level was also higher in the exposed group compared to the non-exposed group (t=3.821, p=
Homocysteine could be a mechanism that underlies the effects of lead on cardiovascular system. This study aims to identify the relationship between lead exposure and homocysteine levels among workers. A comparative cross-sectional study was carried out on 80 workers of an automotive components manufacturing factory; that comprised of 40 exposed workers and 40 non-exposed workers. Blood samples of respondents were taken by fingerprick. The blood samples were analyzed for blood lead concentration by using Atomic Absorption Spectrometry Graphite Furnace Model GBC 908AA. Besides that, ELISA Kit was used to show the homocysteine level among the respondents. Questionnaires were used to obtain demography information of respondents. Results from the statistical analysis showed that the mean blood lead concentration for exposed respondents was 5.53±4.74 μg/dL and 3.53±2.81 μg/dL for the comparative respondents. Mann-Whitney U test showed that there was no significance difference between the mean blood lead concentration of the exposed and comparative group (z=-1.178; p=0.075). The blood lead concentration ranged 0.68-17.95 among the exposed group and with a range of 0.084-11.96 for the comparative group. The mean homocysteine level (μmol/L) was 32.48±2.481μmol/L for the exposed group and 16.50±4.0960 μmol/L for the comparative group. There was a significant difference in homocysteine level (μmol/L) between the exposed (32.48±2.481) and comparative (16.50±4.0959) groups (z = -7.699, p
Two EU directives which are RoHS and WEEE have restricted the usage of certain hazardous substances in
electrical and electronic equipment. This has led to the introduction of green compound which is halogen free. The
non-halogenated molding compound with different recipes was developed by compound manufacturers without
compromising the reliability performance of electronic packages. The focus, often, has been on product reliability
performance while qualifying new materials which overlook relevant safety and health concerns that might incur
during the production stage. This paper is intended to study the forming of crystalline deposits which are found at
the exhaust inlet of the Post Mold Cure Oven (PMC) arising from the usage of this green compound. The writers will
investigate the underlying reasons and the impact on the work environment and the potential risk on health. From the
initial evaluation result, the writers have indentified Compound A as the cause of this deposition. Data analyzed from
the Thermo-Gravimetric Analysis (TGA) revealed higher weight loss which was 0.26% for compound A compared to
other green compounds which are also used. Differential Scanning Calorimetric (DSC) test shows melting temperature
of crystallized particle at 139°C while cold crystallization temperature at 80°C. The temperature in the interior of the
oven is 180°C while the temperature at the exhaust inlet which is exposed to room temperature, and thus, providing
the opportunity for this deposition. Further study carried out using Fourier Transform Infrared (FTIR) spectroscopy
on one of the ingredient of the green compound (material C) observed a 95% spectrum matching compared to the
crystallized particle. Material C is a catalyst added to the mold compound for epoxy-phenolic reaction. It is also
considered to have the capability to enhance flame retardation. This paper will discuss in detail the characteristics of
Compound A green compound and its impact on human and environment.
The question about which is the best approach to facilitate the effective safety evaluation, training processes
involved have become and on-going debate. This article reviews current approaches to evaluation of safety training. It
was focusing theoretical framework suggested and used in the previous literature. Furthermore, possible summary of
several methodologies of safety training evaluation presented.
Licensed person is a third party who was awarded a license to perform statutory inspection for certificated
machinery under the provision of section 40 (1A), Factories and Machinery Act (Amendment) (FMA) 2006. The
objectives of the study is to identify issues related to statutory inspection in Malaysia and to make comparisons with
respect to the statutory inspection by Licensed Person adopted by other countries. The enforcement of Licensed
Person in Malaysia is still in not yet implemented although Section 40 (1A) in FMA (Revision) 2006 regulating on
Licensed Person had been introduced on 2006 and compared with other countries especially our neighboring country
Singapore. Based on the DOSH inspection data analysis, the main issues relating to statutory inspection in Malaysia
is the increment in backlog cases due to lack of number officers compare to the number of registered certificated
machineries in Malaysia. As a conclusion, the implementation of Licensed Person is crucial in Malaysia to reduce the
work and financial burden of Department of Occupational Safety and Health (DOSH) officer in enforcing FMA 1967
and also to improve the quality of statutory inspection for the safety in workplace.
Individual factors have been considered to be a key issue to organizations’ performance and survival. Specifically, previous studies provide evidence that individual factors are closely associated with accidents in the workplace. Therefore, this study seeks to investigate the relationship between individual factors and workplace safety. 50 respondents have been randomly chosen from a manufacturing company in Johor Bahru, Malaysia. Data are collected using a survey and are analyzed using SPSS version 16.0. A descriptive statistic, cross tabulation, independent sample t-test and one-way between groups ANOVA are employed to interpret findings of the study. Findings show that employees’ perception on safety performance is at high level (Mean= 115, Standard Deviation= 17.73). Furthermore, the results of cross tabulation demonstrate that individual factors play a key role to determine the organization safety performance level. Another significant finding reveals that there is a significant difference of safety performance mean to two of individual factors namely gender and tenure of service. Individual factors namely gender, age, tenure of service and academic qualification give a significant impact to employees’ perception on safety performance.
Recent development in industrialization and global economy has contributed to the increased number of workplace
injuries and accidents. Safety culture has been seen as a central medium to curb the worrying trend of workplace
accidents. The term of safety culture has emerged from the Chernobyl nuclear disaster in 1986 and the concept has
been widely used until today. However, the conceptualization of safety culture suffers from several major drawbacks
such as no definite understanding of how safety culture is being defined and measured. This paper hypothesized that
higher levels of safety culture in the workplace will display lower numbers of accidents. Due to this concern, this
paper seeks to provide a clear conceptualization of safety culture, dimensions used to measure it and common research
methodology used in the previous safety research.
Work-related musculoskeletal disorders of the upper limb (WRMSDs-UL) account for one of the largest types of occupational disorders worldwide. This broad term includes several disorders, such as carpal tunnel syndrome, tendonitis, tension neck syndrome and lateral epicondylitis (tennis elbow) which are generally caused by poor postures, repetitive strain and psychosocial factors. Various workplace interventions have been investigated and employed to prevent the different WRMSDs-UL, but a common consensus to address the problem has yet to be achieved. This paper reviews and discusses the efficacies of some interventions which have been tested for the most prevalent type of WRMSDs-UL, carpal tunnel syndrome (CTS). The focus will be on computer users who developed CTS out of the prolonged and repetitive use of keyboards and pointing devices. The interventions studied include engineering design, management strategies, personal development, medical treatment and multi-dimensional approaches. Outcome of the study reveals that the most effective approach would be one that is multi-dimensional in nature, with the inclusion of at least two or more intervention strategies at the same time.
This study analyzes the determinants of workplace injuries across 44 four-digit manufacturing industries in Malaysia from 1993 to 2008 through the business cycle and structural approaches. The results of fixed-effects estimations revealed that workplace injuries in Malaysian manufacturing sector were negatively influenced by firm size and positively influenced by business cycle. Consistent with the findings of previous studies in other countries, the empirical evidence of this study supports the pro-cyclical behavior of injury rates in manufacturing industries towards business cycle. The analysis demonstrates that both structural and cyclical variation effects are important determinants of workplace injuries in Malaysia.
In September 2011 at the 19th World Congress on Safety and Health at Work in Istanbul, I met a Turkish prominent scholar and we exchanged our ideas on the topic of work safety. Turkey, as you well know, is one of the Muslim majority countries and Muslims comprise 99% of the whole population. And I have heard that in Turkey, a fatalism based on its faith is so pervasive among people that Turkey has a lot of cases on injuries and deaths at the workplace. In such a fatalism, an accident would be accepted as a fate which their God has already decided, because of God being in control of everything.
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.
The aim of this paper is to identify, review and carry out comparison to seven guidelines where the main focus is on its risk
assessment elements related to confined space activities. This is due to lack of the specific approach of the Legislation for confined
space such as entry procedure requirements, risk assessment method, existing practice of risk assessment is too general and additional
references are required for conducting risk assessment which would lead to poor response from industries. The selected guidelines will
be summarized on its requirements, followed by a review of each guideline and finally the comparison of Legislations will be carried
out. The results from the study would be used as a contribution factor to promote an ideal method in developing an effective risk
assessment tools for working safely in confined space. Furthermore, several literatures which have been referred could give additional
input for developing the risk assessment tools.
This paper discuss thermal comfort studies of an under air conditioning in hot and humid climate which at one of the higher institution in East Coast of Malaysia. Indoor thermal environment is important as it affects the health and productivity of building occupants. The paper reports on an experimental investigation of indoor thermal comfort characteristics under the control of air conditioning. Firstly, the well known Fanger’s thermal comfort model was simplified for the current experimental investigation. This is followed by reporting the experimental results of indoor thermal comfort characteristics under the control of temperature, with eight different of temperatures which are 22oC to 29oC. Finally, indoor thermal comfort was merely affected by the increment ventilation and outdoor climate. PMV value was higher when near from the window because of the effects of the wall radiations and the metabolic heat.
Studies have identified working postures as a major risk factors associated with Work-related musculoskeletal disorders (WMSD) in industries. This study investigated the prevalence of WMSD among assembly workers in Malaysia and how psychosocial factors such as personal values and workers relationship with family and superior are associated with discomfort and pain. A survey was conducted among 127 workers at assembly process in the manufacturing industry. The workers were aged 28.74±6.74 years and 64.6% of them were males. Analysis of Variance (ANOVA) was used to determine the effect of workplace factors on WMSD at different body regions. Spearman’s rank correlation was used to investigate association between psychosocial factors and occurrence of discomfort and pain. Only occupation and job activities revealed any significant different with WMSD in the major body regions while there was no significant difference in gender, age and work duration classifications. Shoulder painis the most prevalent in terms of frequency and intensity of occurrence. Psychosocial issues that have to do with person values, effect of job on family relationship and workers rapport with superiors are all found to be associated with the discomfort and pain among the occupational group. Employers and concerned government agencies need to take more proactive steps in tackling the problem as the occurrence of WMSD will have a significant effect on the overall wellbeing of the working population.
The increase in Musculoskeletal Disorders (MSDs) cases in the context of manufacturing industry in Malaysia in
the recent years has become a national concern. Therefore, the study aims to compare the severity of the WMSDs cases
involving electronic workers by using survey, interview, observation and experimental methods. The questionnaire
was designed and distributed to 204 assembly workers performing printer and inserting semiconductor in the electronic
sector. The ergonomic risk was assessed through direct observation of workers’ posture at their workstation using
WERA. In addition, Electromyogram (EMG) analysis was used to measure the muscle activity of workers. The result
shows that standing workers are exposed to consistent MSD more than sitting workers in all body regions except for
the upper back. According to WERA results, both postures contribute to high risk of MSD especially at wrist and leg
regions. In conclusion, there is a significant correlation in the findings from the survey, observation and EMG analysis
about the prevalence of MSDs among the workers, although the degree of prevalence differs in some body regions.
Hence, there is a need to identify more interacting variables associated with the problem.
