An ergonomics study of a semiconductors factory in an IDC for improvement in occupational health and safety

Bin WS, Richardson S, Yeow PH

Int J Occup Saf Ergon, 2010;16(3):345-56.
PMID: 20828490

The study aimed to conduct an ergonomic intervention on a conventional line (CL) in a semiconductor factory in Malaysia, an industrially developing country (IDC), to improve workers' occupational health and safety (OHS). Low-cost and simple (LCS) ergonomics methods were used (suitable for IDCs), e.g., subjective assessment, direct observation, use of archival data and assessment of noise. It was found that workers were facing noise irritation, neck and back pains and headache in the various processes in the CL. LCS ergonomic interventions to rectify the problems included installing noise insulating covers, providing earplugs, installing elevated platforms, slanting visual display terminals and installing extra exhaust fans. The interventions cost less than 3 000 USD but they significantly improved workers' OHS, which directly correlated with an improvement in working conditions and job satisfaction. The findings are useful in solving OHS problems in electronics industries in IDCs as they share similar manufacturing processes, problems and limitations.

Simulation of motorcycle crashes with w-beam guardrail: injury patterns and analysis

Ibitoye AB, Hamouda AM, Wong SV, Umar RS

Proc Inst Mech Eng H, 2009 Nov;223(8):1033-40.
PMID: 20092099

This study uses computer simulations to study the impact of a motorcycle with the conventional w-beam guardrail. A three-dimensional computer simulation of a scaled hybrid III 50th-percentile male dummy mounted on a motorcycle and colliding with a w-beam guardrail is carried out. A multi-body model of the motorcycle and finite element model of the guardrail are developed using commercially available software. The simulation model is validated with a physical crash test conducted with same initial impact configurations. Impacts at speeds of 32, 48, and 60 km/h at an impact angle at 45 degrees are considered. The predicted forces and accelerations are compared with the biomechanical limits for each body part and the risk of injury to the rider are evaluated. Speed was found to have a significant influence on the level of injury to the head, neck, chest, and femur. A significant reduction of the severity of injuries was found when the impact speed was reduced from 60 to 32km/h. The accelerations experienced by the head and chest are found to be higher than safe levels for impact speeds of 48 and 60 km/h. The biomechanical limit for the right femur is exceeded at all three considered impact speeds. Neck injuries are also a concern, with the predicted tension values and neck bending extent being higher than the biomechanical limit for the 60 km/h impact speed. In light of these results, it is suggested that the design of guardrails should be reviewed with a focus on the safety of motorcyclists.

Fulltext Handlebar herniation: a case of near missed abdominal injury

Chew KS, Amin NM

Med J Malaysia, 2009 Jun;64(2):170-1.
PMID: 20058582 MyJurnal

Timely identification of specific injuries in a polytrauma case is of paramount importance in order to reduce morbidity and mortality. Unfortunately, some of these injuries are subtle and can be missed on initial primary and secondary assessments. In this paper, we report one such injury in a case of a 16-year old motorcyclist who complained of abdominal pain over the right lumbar region after the motorcycle handlebar hit his abdomen. Although initial assessment was uneventful, he was subsequently diagnosed to have a traumatic abdominal wall herniation on abdominal computed tomography after more than 24 hours of observation in the ward.

Radin Umar RS

Int J Inj Contr Saf Promot, 2006 Jun;13(2):71-9.
PMID: 16707342

This paper presents the approach taken by the Malaysian Government to contain motorcycle casualties in Malaysia. It involves the exposure control, crash prevention, behaviour modification and injury control related to humans, vehicles and the environment based on pre-crash, crash and post-crash scenarios of motorcycle accidents. These initiatives emanated mainly from the research and development carried out by the Road Safety Research Centre at Universiti Putra Malaysia. Recent outcomes from these initiatives are presented and their impact is highlighted.

The value of life and accident costing: a willingness-to-pay study amongst motorcyclists in Malaysia

Mohd Fauzi MY, Nor Ghani MN, Radin Umar RS, Ahmad Hariza H

Appl Health Econ Health Policy, 2004;3(1):5-8.
PMID: 15702934

Motorcyclists constitute a large proportion of total road casualties in Asian countries Unfortunately, studies conducted for the purpose of evaluating the cost of traffic crashes, and cost-benefit analyses of safety interventions, are almost nonexistent in these countries. The loss-of-output approach to valuing life has been used for many years, yet this method has also long been criticised as it results in significant resource misallocation. This study attempts to overcome this problem by estimating the value of a statistical life among motorcyclists using the willingness-to-pay method that is commonly used in developed countries. The study recommends adopting a value of MYR1.1 million (almost five times the previous estimate) per statistical life for public policy analysis involving motorcycle safety.

Sequelae of traumatic laryngotracheal separation: the need for individualized long term treatment plan

Mazita A, Sani A

Auris Nasus Larynx, 2005 Dec;32(4):421-5.
PMID: 16051456 DOI: 10.1016/j.anl.2005.05.002

Laryngotracheal separation is a rare variant of laryngeal trauma. However it is life threatening and potentially fatal. Patients with this injury usually succumb at the site of the accident itself. Here we present two cases of laryngotracheal separation of different etiology and of different outcomes. The treatment advocated for laryngotracheal separation is initially airway stabilization followed by formal repair of the transected trachea. However both our cases illustrates that the outcomes can be different and that a long term treatment plan should be individualized to each patient.

Analyzing the relationships between travel mode indicators and the number of passenger transport fatalities at the city level

Asadi-Shekari Z, Moeinaddini M, Sultan Z, Shah MZ, Hamzah A

Traffic Inj Prev, 2016 08 17;17(6):650-5.
PMID: 26890058 DOI: 10.1080/15389588.2015.1136739

OBJECTIVE: A number of efforts have been conducted on travel behavior and transport fatalities at the neighborhood or street level, and they have identified different factors such as roadway characteristics, personal indicators, and design indicators related to transport safety. However, only a limited number of studies have considered the relationship between travel behavior indicators and the number of transport fatalities at the city level. Therefore, this study explores this relationship and how to fill the mentioned gap in current knowledge.
METHOD: A generalized linear model (GLM) estimates the relationships between different travel mode indicators (e.g., length of motorway per inhabitants, number of motorcycles per inhabitant, percentage of daily trips on foot and by bicycle, percentage of daily trips by public transport) and the number of passenger transport fatalities. Because this city-level model is developed using data sets from different cities all over the world, the impacts of gross domestic product (GDP) are also included in the model.
CONCLUSIONS: Overall, the results imply that the percentage of daily trips by public transport, the percentage of daily trips on foot and by bicycle, and the GDP per inhabitant have negative relationships with the number of passenger transport fatalities, whereas motorway length and the number of motorcycles have positive relationships with the number of passenger transport fatalities.

Murder and robbery by vehicular impact: true vehicular homicide

Nadesan K

Am J Forensic Med Pathol, 2000 Jun;21(2):107-13.
PMID: 10871122

True vehicular homicides are defined as those occurrences in which a motor vehicle is intentionally used as a weapon in taking of a life. A case is presented in which the deceased was traveling in the front passenger seat of a motor car that was deliberately rammed by a heavy jeep that came in the opposite direction, resulting in a serious frontal collision. Immediately after the impact, while the occupants of the car were lying in a dazed condition, the two persons riding in the jeep escaped with a bag containing money that was in the car, leaving the jeep behind. The impact mainly involved the driver's sides of both vehicles. The driver of the car sustained serious injuries but was found to be alive, whereas the front-seat passenger, who did not show any serious external injuries, was found to be in a collapsed state and was pronounced dead on admission to the hospital within 30 minutes of the accident. The autopsy revealed that death was caused by closed hemopericardium from a ruptured right atrium. The evaluation of the external and internal injuries confirmed that the fatal injury and a few serious internal injuries were caused by the seat belt (tertiary-impact injuries). The ruptured right atrium was attributed to blunt abdominal trauma by impacting against the lap belt. The case was a true vehicular homicide in which a motor vehicle had been used as a weapon to kill a person. Various aspects pertaining to road accidents, the safety of the occupants, and the advantage and disadvantage of the safety devices are discussed.

Lumbosacral nerve root avulsion

Chin CH, Chew KC

Injury, 1998 6 13;28(9-10):674-8.
PMID: 9624350

Lumbosacral nerve root avulsion is a rare clinical entity. Since the first description in 1955, only 35 cases have been reported. It is often associated with pelvic fractures and may be missed in the initial clinical examination as these patients usually present with multiple injuries. We present three such cases with clinical and radiological findings. These patients were involved in road traffic accidents. Two had fractures of the sacroiliac joint with diastasis of the symphysis pubis (Tile type C 1.2) and one had fractures of the public rami (Tile type B 2.1). All three had various degrees of sensory and motor deficit of the lower limbs. Lumbar myelogram shows characteristic pseudomeningoceles in the affected lumboscral region. Magnetic resonance (MR) imaging provides an additional non-invasive modality to diagnose this condition.

Fulltext Circumstances surrounding accidental poisoning in children

Azizi BH, Zulkifli HI, Kassim MS

Med J Malaysia, 1994 Jun;49(2):132-7.
PMID: 8090091

Circumstances surrounding accidental ingestion of poisons were investigated in families of 70 hospitalised children. Indian children were more likely to be hospitalised for poisoning. Poor safety measures directly contributed to poisoning incidents. Poisons had not been stored safely and only in 12.9 per cent of families were the poisons allegedly kept in cupboards. Kerosene had been ingested from soft drink containers in 70 per cent of instances. Medications had been taken mainly from plastic envelopes (57.9%) or bottles (31.6%). Safety practices in the homes of cases and 140 controls were compared. As a whole parents of victims had poor safety practices when compared with parents of controls. Poisoning incidents were discovered by mothers in 75.0 per cent of the cases. Vomiting was induced by parents in 32.3 per cent of cases involving medications and non-volatile items, and in 41.6 per cent of kerosene ingestions. Before hospitalisation 59.4 per cent were brought to general practitioners and 22.7 per cent to government clinics. Mothers were the main attendants when children were brought for medical care. This study highlights the need for measures to prevent childhood poisoning and reduce its morbidity. Household products and medications should be made safer to children through improved packaging, prescribing instructions and education. Safety and first aid education may be directed towards parents, particularly mothers, through the media and health facilities.

The dental identification of victims of an aircraft accident in Malaysia

Nambiar P, Jalil N, Singh B

Int Dent J, 1997 Feb;47(1):9-15.
PMID: 9448783

On 15 September 1995 a Malaysian Airlines (MAS) Fokker 50 plane plunged while descending and crashed, killing thirty-four passengers aboard. The dental disaster victim identification team comprising dental surgeons from the Dental faculty, University of Malaya; Ministry of Health, Sabah; and the Malaysian Defence Forces played an active role in the identification process. Most of the bodies were badly mutilated, disfigured and severely incinerated. Problems were encountered due to inadequate facilities and space at the mortuary. Difficulties were also encountered during the procurement and deciphering of information from dental records. This disaster has however created greater awareness amongst Malaysians of the important role of forensic odontology in mass disasters.

Measuring driver responses at railway level crossings

Tey LS, Ferreira L, Wallace A

Accid Anal Prev, 2011 Nov;43(6):2134-2141.
PMID: 21819844 DOI: 10.1016/j.aap.2011.06.003

Railway level crossings are amongst the most complex of road safety control systems, due to the conflicts between road vehicles and rail infrastructure, trains and train operations. Driver behaviour at railway crossings is the major collision factor. The main objective of the present paper was to evaluate the existing conventional warning devices in relation to driver behaviour. The common conventional warning devices in Australia are a stop sign (passive), flashing lights and a half boom-barrier with flashing lights (active). The data were collected using two approaches, namely: field video recordings at selected sites and a driving simulator in a laboratory. This paper describes and compares the driver response results from both the field survey and the driving simulator. The conclusion drawn is that different types of warning systems resulted in varying driver responses at crossings. The results showed that on average driver responses to passive crossings were poor when compared to active ones. The field results were consistent with the simulator results for the existing conventional warning devices and hence they may be used to calibrate the simulator for further evaluation of alternative warning systems.

How safe are standard certified motorcycle safety helmets? Malaysian postal delivery riders scenario

Yellappan K, K C Mani K, Md Tamrin SB

Traffic Inj Prev, 2019;20(6):624-629.
PMID: 31329467 DOI: 10.1080/15389588.2019.1626985

Objective: The objective of this study was to determine the proportion of motorcycle safety helmets (MSHs) used by postal delivery riders (PDRs) that comply with the Standards and Industrial Research Institute of Malaysia's (SIRIM) MSH standard guidelines and identify factors that contribute toward compliance of used MSHs with the standards. Methods: The presence of SIRIM certification label, the status of MSH, type of chinstrap, MSH crash history, and duration of MSH use were observed. The dependent variable was the results of the SIRIM testing procedures (SIRIM tests). MSHs that passed the SIRIM tests were considered "standard certified" MSHs. Results: The odds of the complimentary MSHs passing all of the SIRIM tests were 3.7 times the odds of the self-purchased MSHs passing the tests. The odds of MSHs with the SIRIM certification label passing all of the SIRIM tests were 24.2 times the odds of MSHs without the SIRIM certification label, and the odds of MSHs used <3 years passing the SIRIM tests were 3.75 times the odds of the MSHs used ≥3.8 years. Conclusion: PDRs provided with complimentary MSHs with the SIRIM certification label by the employer for their daily delivery routines and duration of MSH used for less than 3 years were found to be safe MSHs for male occupational riders in Malaysia.

Coercive pressure as a moderator of organizational structure and risk management: Empirical evidence from Malaysian construction industry

Tagod M, Adeleke AQ, Moshood TD

J Safety Res, 2021 06;77:139-150.
PMID: 34092304 DOI: 10.1016/j.jsr.2021.02.011

INTRODUCTION: The construction industry in Malaysia has been bedevilled by myriads of risk issues that have hampered its smooth operations in recent times. This paper is an empirical assessment that aims to examine the effect of coercive pressure on the relationship between organizational structure and construction risk management among construction industry in Malaysia.
METHOD: Based on the proposed model, a quantitative method was employed to obtain data from G7 construction industry operating within the peninsular Malaysia. Out of the 180 copies of questionnaire, 165 copies were properly filled, returned, and used for the analysis. PLS-SEM was used to analyze the obtained data.
RESULTS: The findings of the study affirmed that specialization, centralization, and management of risk by the construction industry had positive correlation.
CONCLUSIONS: As anticipated, coercive pressure had positive moderating correlation with both formalization and the management of risk by the construction industry. Similarly, it was also found that in the course of carrying out construction activities, coercive pressure made significant interactive influence on formalization, specialization, and centralization. Practical Applications: Coercive pressure reduced the frequency of accidents among workers in the process of carrying out construction works.
