health resources, related legal requirements, code of practice and directives, sources of potential mercury exposure,
and how health surveillance is conducted. It shares BASF’s experience in analyzing and controlling exposure to
mercury. The paper discusses the similarities and differences of the BASF Ludwigshafen approach with respect to
health surveillance practice for mercury in Malaysia.
Malaysia is blessed with oil and gas resources, which form raw materials for the petrochemical industry. The petrochemical industry creates added value to this resource and is an important contributor to the national economy. The petrochemical industry however also creates hazards of which fire or explosions and chemical release are of special concern. These hazards pose a risk not only to workers but also to the surrounding population and environment. To ensure industry is prepared to cope with emergencies, a comprehensive emergency response programme is necessary. This is inline with both the Malaysian Occupational Safety and Health (Control of Industrial Major Accident Hazards) Regulations 1996 and the Responsible Care initiative of the chemical industry. This paper describes elements to be considered in an emergency response programme for industry such as the concept of emergency management, organisation, duties and responsibilities, emergency system, training and mutual aid plans and agreements. We shall provide related examples based on a multinational petrochemical company practice.
There is a high prevalence of chronic diseases in the community. Promoting health at the workplace is an effective measure to manage such diseases. This study shares the findings of country-wide company health screening program. The prevalence of high cholesterol among participants was 29 %, high blood pressure was 8% and high blood sugar was 3%. The prevalence of high cholesterol from workplace screening was higher than the community prevalence but the prevalence of high blood pressure and high blood sugar was lower than the community prevalence. The various factors influencing these findings are discussed.
How people perceive risk influences their behaviour towards these risks. We do not know how workers perceive risk of dying from activities or technology. This study was conducted among 198 workers of a security company in Malaysia. The workers were asked to score on a Likert scale of 1 to 5 the perceived risk of death of Malaysians from activities and technology. The highest perceived risks of death were, in order of ranking, motorcycles, motor vehicles, handguns, alcoholic beverages and smoking. The difference in perception and reality is discussed.
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.
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.
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.
The objective of this study is to identify the type of occupational related musculoskeletal disorder among Malaysian Shipping Industry workers and to determine the relationship between workers sosio demographic factors with occupational related musculoskeletal disorder and injuries. This is a cross sectional, retrospective study using secondary data that is available at the physiotherapy centre of Malaysia Shipping in Selangor. The study population is the shipping port workers received physiotherapy treatment from 2011 and 2012. A total of 90 samples comprise of 85 male workers and the remaining is female. The mean age is 34.1 (±7.36). Crane operator is the largest number of workers seeks for physiotherapy treatment (68), office (15) and 7 from maintenance. The mean of employment duration is 8.02 (±4.47) years with the maintenance group of workers have longest working duration of 9 years. Muscle and ligament sprain strain known to be the commonest condition (80%) refer for physiotherapy rehabilitation, tendinitis (14%) and fracture (6%). Young age group of workers were significantly 9 times higher (95% CI 1.83 – 40.35) of getting back injuries. The prevalence of musculoskeletal disorder based on work categories vary with office type workers has 4.5 times higher (95% CI 1.06 – 19.7) on hand injuries. This study has revealed that workers age, different type of work categories, working experience, and body mass composition were associates with the occupational related injuries. The training programme emphasise on preventive measures should be tailored to empower the employee on safety measures at work.
Work-related Musculoskeletal Disorders (WMSDs) are common occupational injuries among workers in the construction industry. Epidemiological studies indicated that WMSDs include neck pain, lower back pain, knee pain, leg fatigue as well as ankle and feet discomfort. The objectives of this study are to identify the WMSDs experienced by the workers during construction works and discuss the causes of those WMSDs. Subjective approach associated with modified Nordic Musculoskeletal Questionnaire (NMQ) was applied to identify the symptoms of WMSDs. A case study was conducted in several construction sites situated at the southern region of Peninsular Malaysia. During the study, 37 construction workers with different age and scope of works were interviewed to determine the WMSDs that they have experienced. Based on distributed questionnaire, almost all workers experienced pain in the region of lower back, upper back and biceps. These pains were contributed by manipulation of heavy load and high force exertion. Based on discussed causations, control measures via engineering controls method and administrative controls method were proposed to alleviate the risk of WMSDs among construction workers.
Comparative cross sectional study was conducted to determine the prevalence of hearing impairment among workers in one of the airport in Malaysia and the factors associated with it. A total of 248 subjects comprising 175 from the exposed group and the remaining control group were sampled. The main tools used in this study were validated questionnaire on hearing assessment and pure tone audiometric test. Response rate was 94%. Both area and personal exposure monitoring have exceeded action level for 8 Hrs TWA in the exposed group but within normal limit in the control group. The prevalence of hearing impairment was 88% among the noise exposed group and 11% in the control group with prevalence odds ratio (POR) 3.569 (95%CI 1.210-10.53, p
Occupational health hazards as a result to exposure to mineral dust containing silica has been established long time ago in occupational health history. Its effects on lung function and symptom was evaluated in a cross sectional studied among 49 small enterprise pottery workers in the county of Sayong clustered in 3 villages. Respiratory symptoms and lung function was evaluated using MRC respiratory questionnaire 86 and standard spirometry performed. The prevalence of chronic cough, phlegm and chest tightness was 24.5%, 16% and16% respectively. There was no significant decrement in lung function parameters from the predicted normal value with the mean predicted FVC; FEV1 and FEV1/FVC ratio was 85.32%, 83.87% and 99.22 respectively. The relationship between lung symptoms and lung function parameters was evaluated and the result was not significant.
Precast concrete panel is one of the Industrial Building System (IBS) components currently used in modern construction industry, especially, in a highly populated urban area in Malaysia, owing to its cost and time efficiency in a project completion. However, the constraints lie in Musculoskeletal Disorders (MSDs) when IBS workers manually lift the concrete panel repeatedly. The aim of this study is to analyze the recommended weight limit (RWL), lifting index (LI) and physiological experience among workers while lifting precast concrete panel with 3300mm x 600mm size and compressive strength of 40MPa. The methods involved include a survey through the Nordic questionnaires, interview sessions, NIOSH lifting index calculation, recommended work limit calculation, Rapid Upper Limb Assessment (RULA) and video recording. The results yielded the MSDs problem. The guidelines of recommended weight limit and lifting index are produced. They benefit workers and increase their awareness on the MSDs issues.
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 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.
Introductions: Call center has been defined as a working environment in which uses telephone and computer for the purpose of marketing and manage communication with prospect clients or existing clients (Rocha, Glina, Morinho and Nakasato, 2005; Sprigg, Smith and Jackson, 2003).
Methodology: The study was conducted via observation of working condition and face to face interview with call center operators. Measurement of anthropometrics was also conducted.
Results: Ergonomics issues found at call center were inappropriate work condition and workstation which lead to awkward sitting posture (sitting with forward leaning posture, raised shoulder, feet not supported on floor). Besides that organizational policy which required high job demand and subsequently lead to prolonged sitting and static posture (very minimal posture changes). Combination all these factors lead to musculoskeletal symptoms and the operators reported of having neck, shoulder, upper back and lower back pain compared to other body parts.
Conclusion: The management should embark on organization wide ergonomics management program and should review the current policy and create safe and healthy working environment by providing suitable workstation for the operators in order to prevent musculoskeletal.
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.
There is a need to develop an Occupational Safety and Health Management System (OSHMS) Critical Success Factors (CSF) Monitoring among gas contractor in Malaysia. Critical Success Factors (CSF) can be used for future implementation, adaptation and practice for gas contractor work for both by clients and contractors in Malaysia. The main purpose of CSF implementation is to reduce the number of accident related with Occupational Safety and Health (OSH). The need for CSF is due to the requirement by law and standard that require companies to establish an arrangement related to the identified OSH risks. The objective of this study is to assess the established of OSHMS among gas contractor in Peninsular Malaysia and to identify the CSF imposed by these industries. A cross sectional study for eighty gas contractor companies using established questionnaire has been done. All data consolidated in order to determine the OSHMS and it CSF among gas contractor in Peninsular Malaysia that has registered with Department of Occupational Safety and Health. Established questionnaire are based on OSHMS MS 1722:2011 elements requirement No 1: Policy, No 2: Organizing, No 3: Planning and Implementation, No 4: Evaluation and No 5: Action for Improvement as parameters to come out with organization means and Z-scores. Descriptive statistic showed that element mean (standard deviation) score for policy is 75(6.6), for Organizing is 63(5.2), for Planning and Implementation is 59(9.4), for Evaluation is 66(5.1) and Action for Improvement is 63(1.3). Percentage of company that complies with the main element for Policy is 15%, for Organizing is 8.8%, for Planning and Implementation is 11.3%, for evaluation is 11.3% and for Action for improvement is 13.8%. Percentage of companies that partially comply with Policy element is distributed between 61.0% to 85.0% which is 76.3 %, for Organizing score is mainly distributed between 46.0% to 60.0% which is 62.5%, for planning and Implementation score for 80 companies distributed mainly in group score between 46.0 to 60.0% which is 56.3 %, for Evaluation the partially comply score is distributed in group score between 61.0% to 85.5% which is 41 % and for Action for Improvement partially comply score, the distribution is mainly distribute in range of 61.0% to 85.0% which is 62.5 %. Z-score for element policy is five points from policy mean, for organizing Z-score is three points from Organizing mean, for Planning and Implementation the Z-score is three points from Planning and Implementation mean, for Evaluation the Z-score is three points from evaluation mean and for Action for improvement Z-score is two to three points from Action for Improvement mean. Percentage of compliance with OSHMS MS 1722:2011 elements by gas contractors in almost main element and sub element are still low and can be further improved by focusing on all company element score for continual improvement of OSH elements compliances.

A cross sectional study to determine the exposure of heat and its biological effects on the workers in a plastic factory located in the Shah Alam Industrial Estate, Selangor, Malaysia. Forty five respondents from the polymer section in the factory were selected as the respondents. Variables measured were the environmental temperature (WBGTin), air velocity, relative humidity, body temperature, average heart and recovery heart rate. QUESTEMP°34 Area Heat Stress Monitor was used to measure the environmental temperature in °C (WBGTin) and relative humidity (%). Velocicheck Model TSI 8830 was used to measure the air velocity in meter per second (m/s) while the OMRON Blood Pressure Monitor Model T3, was used to measure average heart rate and recovery heart rate. Body temperature (°C) was measured by the Instant Ear Thermometer-OMRON Gentle Temperature Model MC509. Interviews using questionnaires were used to determine respondents’ socioeconomic background, previous risk factors on heat exposure and other information related to heat stress. Results showed that the mean environmental temperature for the exposed group was 28.75°C, the mean air velocity was 0.15 m/s and the mean relative humidity was 58.1%. These production workers were exposed occasionally to heat when loading plastic powder into the molds as well as demolding the finished plastic products from the molds. The average time of monitoring was 2 hours for intermittent exposure and 8 hours duration for overall exposure. Maximum demand for work load was measured 1 minute after work activities were stopped at the demolding section. There was a significant difference between body temperature and average heart rate before work, after 2 hours of work and after 8 hours of work ( p < 0.001). The mean recovery heart rate after 1 min was 88.0 ± 12.0 beat per min. (bpm), indicating that there is no excessive physiological demand. Body temperature (36.8 ± 0.40°C) and average heart rate after 8 hours (78 ± 12 bpm) indicated a good body control of heat exposure. Five out of six workplaces monitored had temperatures of greater than 28°C (ACGIH TLV). The workers were exposed to moderate heat stress during the study period, however, body temperature and average heart rate measurement did not reach unacceptable level of physiologic strain.
The paper writes on the possible origin of off-limit cases found in a noise project conducted internally in a factory in Malaysia. Out of 691 sampled workers’ that attended audiometric test results (some repeated), it was found that the mode of hearing ability is between 20 to 30 dB depending on individual worker’s age ranging from 20 to 55 years. Out of the total results, approximately 100 workers are above a limit defined here in this paper as the off-limit condition. The chance of a worker originating from a good condition to an unhealthy condition is about 1 percent. The data are tabulated to show that a sway pattern could be an explanation of workers’ origin. Although the data is profound, there is no evidence of a trace due to a short test period. Possibilities are highlight here to outline the severity of a cross over to the unhealthy condition (here defined as the off-limit condition). Some advises are mentioned here with individual susceptibility on the matter though there is no data to substantiate. Further findings are required to show a trace. In conclusion, the severity is highlight. A chart, developed to know the limits of hearing ability, is illustrated ased the findings.
