Pineapple plantation workers are exposed to strenuous physical activities. This study aims to determine the prevalence
of musculoskeletal symptoms (MSS), analyse the body postural risks related to work tasks and identify relevant MSS risk factors
among pineapple plantation workers. This was a cross-sectional study performed at a pineapple plantation in Johor in 2016. MSS,
information on socio-demographic background and occupational history were collected via structured questionnaires. Identification
and risk assessment of ergonomic hazard and postural risk analysis were performed for a subset of workers. Data were entered into
statistical software and analyse according to relevant objectives. A total of 108 workers participated in this study. The prevalence
of MSS was 87.0% and was highest for the lower back (64.8%). In terms of ergonomic hazards, Harvesting were categorised as a
task with the highest risk. Harvesting was also the task with the highest postural risk. From the multivariate analysis, lower back
pain is mainly contributed by a working tenure of 10 to 25 years (Odds Ratio, OR: 3.90; 95% Confidence Interval, CI 1.05-14.4) and
more than 25 years (OR: 7.45 (95% CI 1.26 to 44.0). Workers who worked more than 7-hour daily have a higher risk for reporting
lower back pain. Pineapple plantation workers are exposed to excessive bending, twisting and carrying of heavy loads that may be
linked to MSS. Effective preventive strategies are required to address MSS in this population in order to minimize risk for subsequent
musculoskeletal disorders.
Local Exhaust Ventilation (LEV) is required to absorbed the chemical and at the same time to maintain the air quality. This
study is purposed to create new design of LEV system that believe can remove air contaminants in the chemical store buildings. This
research was conducted using two (2) types of LEV system which are 4 air-inlets LEV (type 1) and 3 air-inlets LEV (type 2). That LEV
has been simulated using ANSYS FLUENT software for their air flow performances. LEV material and the cost of production were
considered parameter for fabricating and effectiveness of LEV system. Results show that air velocity in LEV type 1 was gradually
uniform throughout its ducting network but it increased at the 90º bend section with a maximum air velocity of 31.054 m/s. In the LEV
type 2, the air flow simulations depicted uniformity velocity values of 8.12 m/s, 8.58 m/s and 7.69 m/s at every inlet respectively. The
finding suggests that LEV type 2 was more efficient compared to LEV type 1 due to increasing streamline air velocity.
Poor IAQ would lead to the occurrence of Sick Building Syndrome
(SBS) and other symptoms. This study aimed to investigate the IAQ and the symptoms
of SBS among the office workers in the two selected buildings (old and new). A
comparative cross sectional study was conducted among 90 office workers from an
old building (26 years of age) and a new building (5 years of age). The SBS symptoms
were assessed utilising the questionnaires adopted from Industry Code of Practice
(ICOP) 2010 while IAQ parameters were monitored using the Handheld 3016 IAQ
Particle Counter and Multi-Function Ventilation Meter. All the parameters studied
were below the standard limit as set by the Department of Occupational Safety and
Health (DOSH) and the United States of America’s Environmental Protection Agency
(US EPA) except for air velocity in the old building which was lower than the
acceptable standard range. The levels of PM10 and total particulate matter (TPM) in
the old building was significantly higher as compared to the new building (PM10: Z=
-2.495, p = 0.013 and TPM: Z = -2.873, p = 0.014). The SBS prevalence was 51.1%
among respondents at the new building while 64.4% for old building. However, the
difference was not statistically significant (p > 0.05). There was a significant
association of drowsiness among respondents between old and new building (2=
4.050, p = 0.044). Therefore, in order to ensure a good IAQ, regular maintenance of
ventilation and control measures should be conducted.
Recent fire accidents in schools have given rise to the safety
issues. Training on fire safety is very important to help improve the safety aspect
in schools while perceptions of fire safety training among school teachers are
crucial in order to identify methods to prevent accidents from recurring. This
study was conducted in order to analyze the perceptions of school teachers
towards fire safety training in schools. Survey questionnaires were distributed
among 400 school teachers from 111 schools randomly selected from ten District
Education Offices (DEO) in Kelantan. The results were analyzed using
Statistical Package for the Social Sciences (SPSS). They were based on 32% and
68% male and female respondents respectively. Descriptive analysis shows that
most of the school teachers agreed with the need for fire safety training to be
conducted in schools. This study suggests that school teachers require fire safety
training in order for them to help improve fire safety in schools. Thus, teachers
will be able to teach their students on the importance of fire safety, how to
prevent fire and actions to be taken if an emergency happens in schools. It is
hoped that the number of fire accidents in schools can be reduced with the school
communities’ commitment towards safety.
In order to have an effective preventive measures to reduce accidents
at the workplace, organisations need to take a robust step to increase safety
participation in Occupational Safety and Health Management System (OSHMS).
Accidents will affect employees' morale for work and employers will bear the
consequence of the direct and indirect recovery cost. Specifically, accidents will
cost big company’s good reputation. This study intends to examine the
relationship of organizational safety factors (management safety commitment,
safety training, extrinsic reward, intrinsic reward, employee involvement, safety
communication and safety advice) towards safety participation in OSHMS using
the resource-based view (RBV) and knowledge-based view (KBV) theories. A
total of 100 responses were analysed from the Malaysian manufacturing firms
with OHSAS 18001 or MS 1722 certifications. Data were analysed using
the Smart Partial Least Square (SmartPLS). It is found that safety training and
employee involvement have direct relationship towards safety participation in
OSHMS. Specifically, the safety advice showed a significant moderating effect on
the relationship between management safety commitment and safety
participation in OSHMS. The findings of this study are useful to both OSH
practitioners and organisation who wish to understand and apply safety capital
towards safety participation in OSHMS with specific reference to the role of
safety advice played by safety professionals.
This is a conceptual paper to study the factors that affect the
safety practitioner’s perception towards safety and health risk assessment,
namely HIRARC at oil palm plantation. Retrospective safety and health data
were obtained and analysed. Factors identified were both confusions on
hazard description and interpretation of risk assessment matrix. This paper
will examine those factors and make recommendations for future research in
Malaysia.
The low back is usually associated with the lumbar spine which supports the entire weight of the upper body and significantly, is vital to the body mobility. Injury to the surrounding soft tissues can cause mild to debilitating symptoms due to muscle strain and ligament sprain. The causes of injury to the lower back are probably due to sudden twisting movement, poor posture position at work and manual handling of heavy objects or with twisting or bending movements while lifting. An Ergonomic Risk Assessment was carried out on a dental laboratory worker who complained of unresolved low back ache after a year on treatment and follow up at the outpatient department of a health clinic. From the various investigative methods used, it was found that the worker in question was placed in a situation that will over time encourage her to develop musculoskeletal disease. Our recommendations for change include immediate awareness and training in ergonomic principles of work and to report all cases so that appropriate action can be taken, reassess the workstation and environment of work, job enrichment, and creating a conducive environment for work. Once the changes have been implemented, a review will be necessary in three months time.
A cross sectional study was conducted among tea plantation workers in Cameron Highlands from July to December 2006 to study the prevalence of low back pain and factors associated with it. One hundred and six tea plantation field workers participated in the study. Data was collected using self-administered questionnaire. Time motion studies were also conducted for 3 different job categories. The prevalence of back pain experienced throughout their work in the plantation was 81.1% and the prevalence of low
back pain experienced in the past 12 months was 64.2%. Feeling the need to work as fast as possible was a significant predictor of low back pain and increased the risk by 3.5 times, therefore it is suggested that both the management and workers give serious attention to this particular aspect to reduce the incidence of low back pain.
Computer work is common at shared service centres and employees are exposed to risk of musculoskeletal symptoms.
Although employees at this service centre had already been advised to complete an ergonomics self assessment using a checklist and
consult an occupational health doctor if symptomatic, almost half participants responded they were either unaware or unsure of the
company’s ergonomics self assessment checklist and all did not mention consulting an occupational health doctor if symptomatic.Most
participants had at least one musculoskeletal symptom. The main location of musculoskeletal symptom reported was shoulder, neck
and lower back. This was consistent with main location of musculoskeletal symptoms reported due to work which were shoulder, neck
and lower back. Most of the musculoskeletal symptoms affected wellbeing at work and almost half were at least moderately severe.
The incorrect posture often observed were: upper arm not close to body, shoulder not relaxed and hand not in-line with forearm..
The musculoskeletal symptoms reported were consistent with observation of incorrect posture. There is an urgent need to enhance the
effectiveness of the ergonomics program at this service centre.
The cultivation of indoor plants in indoor environment has become a topic of interest among researchers worldwide for its
potential to improve indoor air quality (IAQ). However, the adaptations of environmental factor of each plant need to be investigated
to correspond with the native environment. The study investigate the capability of plants selected to live indoor. Before experiment was
conducted, all plants selected were assimilated with indoor environment for two months. Photosynthesis proses in this experiment will
be a guidance to determine the comparative for every plant. The portable photosynthesis system equipment (LI-COR 6400) was used to
determine the level of photosynthesis rate for each of plants. Accordingly, among of all plants tested, Spider Plant showed less effective
to be grown with indoor environment by the rate of photosynthesis value up to -0.15. Moreover, light compensation point (LCP) of
Spider Plant also indicated the light intensity consumption was 2960 lux which is extremely higher than 300 lux. As a conclusion, only
six plants in this study which are Anthurium, Dumb Cane, Golden Pothos, Kadaka Fern, Prayer Plant, and Syngonium are able to
survive with indoor environment. In the next stage of study, this six plants may give good results to enhance the IAQ.
Indoor air quality (IAQ) can be described as the quality of air weather inside or surrounding the buildings and structures
which are associated with the health and comfort ability of occupants in the buildings. The level of IAQ in buildings can be influenced
by microbial contaminants activities, chemicals exposure and allergens that seriously can create health effects to the building’s
occupants. In the present study, the effect of environmental factors such as temperature and relative humidity on the optimum growth
of Aspergillus niger (A. niger) was investigated. The study revealed that the optimal fungal growth of up 43mm in diameter was
evidenced under room temperature of 30oC at the end of a five day incubation period. However, the relative humidity from 40% to 90%
applied is able to support the growth of the A.niger. The relative humidity of 90% shows the optimal effect where 56 mm of diameter
growth happened after 5 days of incubation. The significant finding to emerge from this study is that environmental factors such as
temperature and relative humidity do affect the growth of A.niger. The optimal temperature and relative humidity for A.niger to grow
are 30oC and 90%, respectively.
Concerns toward Indoor Air Quality (IAQ) in office building tend to risen since most people spend their working hours
indoors compare to outdoors. Exposure to indoor pollutants is a considerable problem. Therefore, there is a need to monitor IAQ in
order to deter further air quality deterioration in the workplace. The objective of this study is to determine the level of IAQ parameter
in selected academic office. The important IAQ parameters considered in this study were the air temperature, air velocity, relative
humidity, CO2, CO, TVOC, formaldehyde and respirable particulate matter. Measurements were conducted using commercial IAQ
instruments. From the study it was found that the levels of TVOC and respirable particulate matter were higher than the recommended
limit during photocopying activities. The formaldehyde, CO2 and CO level were observed to be acceptable for an office based on
Industry code of practice on indoor air quality (ICOP-IAQ 2010). Results shows that the temperature and air velocity are located at
acceptable value of 22-25 ºC and 0.1-0.1 m/s. Findings also show high relative humidity that exceeded the requirement level of 40%-
70%. Detail investigations are needed in order to provide certain guidance in improvement of IAQ conditions in office environment.
Students’ knowledge, attitude and practice towards safety and health are one of the important aspects of their learning
process in school. Negligence of this aspect can increase the risk of accidents among students. This study was conducted to assess the
level of knowledge, attitudes and practices (KAP) of students toward safety and health aspects in school. This study was participated
by 410 Form Four students that were randomly selected. They are from SMK Sultan Alauddin Riayat Shah 1 (SARS1), SMK Taman
Dato’ Harun (SMKTDH) and SMK Agama Sheikh Hj. Mohd Said (SHAMS). Questionnaire used consists of demographic components,
knowledge, attitude and practice items towards safety and health aspects. Majority of the respondents are female students (58.3%)
while the rest are male students (41.7%). Higher percentage of respondents are from SMKTDH (59.5%) followed by SHAMS (24.1%)
and SARS1 (16.3%). This study found that the level of knowledge, attitude and practice of students toward safety and health aspects
in school are high. The mean score of all knowledge, attitude and practice items in the questionnaire are 4.29±0.40, 4.07±0.46,
and 4.13±0.48, respectively. In addition, this study found that the school factors are significantly associated with student’s attitude
and practice, while the gender factor is only significantly associated with student’s attitude towards safety and health in school.
Meanwhile, correlation analysis showed a significant relationship between student’s knowledge, attitude and practice (p
The global demand for palm oil is growing, thus prompting an
increase in the global production. Such increasing demand for palm oil is due to
palm oil’s relatively cheap price and versatile advantage both in edible and nonedible
applications. Being world second largest producers, Malaysia’s palm oil
industry is growing in complexity and successively to succeed on the global level by
accounts for about 30% of the world production of palm oil in 2015/16. But,
reliability and safety issues are still problematic areas that need to be addressed by
all parties in this industry e.g. millings, refineries and oleochemicals. Although there
are laws and guidelines that provide protection for reliability, safety and health such
as OSHA 1994, OHSAS 18001 and MS 1722, palm oil industry is relatively lacking
behind in process safety as several catastrophic accidents occurred were believed
caused by process safety failures. Therefore, process safety management in palm oil
industry must be enhanced to standard similar to other industries such as chemical
process and oil and gas industries, so that it can prevent major hazard accidents
which can result in fatality, asset damage and environmental impact. This papers
investigates the needs of process safety management in palm oil industry and
proposes a generic process safety management framework which may be useful for
palm oil industry. From the study, it can be concluded that proactive actions are
certainly required to overcome process safety issue in palm oil industry as several
catastrophic accidents occurred were believed caused by process failures.
The purpose of this study is to assess the preferred temperature
(Tpref) of human participants exposed to air-conditioned temperature variations in
climate chamber experiments. Findings were later compared with an earlier Tpref
experiment by de Dear et. al. (1991). Twenty nine healthy college-age participants
underwent thirty minutes of preconditioned session before casting their thermal
preference and thermal sensation votes every 10 minutes for the remaining 150
minutes of the experiment. These affective votes were correlated against average of
ambient air temperature and participant's body temperature taken 30 minutes
before the experiment ends. The mean Tpref was 25.1°C (± 1.2), mean skin
temperature of 33.7°C (± 0.6) and mean body temperature of 36.3°C (±0.3). It can
be concluded that Tpref gathered in the preferred temperature experiment shows
significant difference in participants’ temperature preference which was 0.6 °C
cooler than earlier experiment suggesting change in how indoor ambient
temperature is preferred. In addition, mean skin temperature and gender did not
influence participants’ Tpref.
The occurrences of occupational accidents and incidents are increasing in parallel with the growth of industries
such as mining and quarrying. The main objective of this study was to analyze data on the perception of occupational
accidents in the mining and quarrying sector in Malaysia. The data was collected and examined based on the
questionnaires on the level of perception of accident investigation in mining and quarrying sector. Statistical data
reported by the Department of Occupational Safety and Health (DOSH) was also reviewed. The findings of this study
prove that the level of perception of workers towards occupational accident issues in mining and quarrying sector
is still in the moderate level with the mean value of 3.28. The findings show that 51.7% of the workers agree while
25.9% totally agree to the accident occurrence. Only 1.7% of the workers are not aware of accident occurrence at the
workplace. Employers and employees must carry out their responsibilities to prevent accidents by adhering to health
and safety practices at the workplace.
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.
In the development of current vehicle capabilities required an effective braking system, has a little wear, and
safety riding. The objective of the research is to determine wear and braking distance because of braking load and
speed motorcycle Honda supra X125 cc. This research used the speed of 50 km/h, 60 km/h, and 70 km/h. Braking load
used to be 4 kg, 5 kg, and 6 kg. The test was done by dynamic method and the research was done in two stages; testing
in the field and measuring brake wear in the lab using a profile projector. Testing the hardness of brake was done to
know hardness brake before and after testing due to the effect of wear, braking time, and braking distance.From testing
it was found that increasing of braking load, resulted in increasing wear. The smallest wear was 6 x 10-5 mm/sea at a
speed of 50 km/h, braking load of 4 kg, and braking time of 15.94 seconds. Increasing the speed resulted in increasing
braking distances with the smallest of braking distance was 55 meters at the breaking load of 6 kg, the speed of 50
km/h and braking time 9.93 seconds. The hardness of brake lining, increased after the brake lining wear testing. The
hardness before the test was 95.8 HRN and after the test was 100.4 HRN.
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
the southern region of peninsular of Malaysia. The objective of this research is to determine the level of awareness of
SME owners and also their employers towards the importance of implementing OSH in their daily tasks. This study
will be based on conducting a survey to 200 SMEs owners and workers throughout the southern region of Malaysia.
The results from this research can be use as a benchmark for other researchers to further enhance the research in this
area.
Brake pad apparatus is designed for help student and instructor in teaching and learning application. The objective
of this research is to differentiate the pressure effect and braking temperature condition of different pad. This apparatus
also aimed for learning the safety car and motorcycle braking system. This apparatus can to compare with theoretical
calculation in order to approve that this apparatus is useful. The main concept in this apparatus is thermocouple use
to detect the temperature gain while braking process. Speed motor controller used for set the angular velocity of the
motor in braking process. Pressure applied at brake pedal detected by pressure gauge and data logger function as a
connector. This apparatus also designed based on valid data for average of teenager in Malaysia which made on a
sample university student. Result show that the apparatus can function effectively by defines the different temperature
when applied the different pressure and different pad. Pad C shows the 880C for thermocouple 1 and 790C for
thermocouple 2 at the 20 psi and infrared thermometer show 1130C for pad C. Graph from calculation shows that the
pad A have 216.480C at 1000 rpm which have low temperature than pad B, C and D. high efficiency of friction and
pressure applied will cause more heat generate than low coefficient of friction and pressure applied.
