An evaluation of Manutention training in preventing back strain and resultant injuries in nurses

As the number of manual handling injuries in carers and nurses continues to be very high, the problem of how to prevent injury has not been solved. Despite the obvious need for optimum working environments, the literature does not really support that an ergonomics or systems approach solves the injury problem. Similarly, the evidence for training as a preventive strategy is equivocal, although clearly people handling requires trained handlers for both their own and the patient's safety. This research aimed to evaluate the outcomes of training in a method of manual handling of people, Dotte's Manutention method, which claims to decrease back strain and effort in carers. The study evaluated handling techniques and injury outcomes of a group of nurses in a nursing home trained in this method, using two other homes as comparisons. The study hypothesized that training in the Manutention method would decrease back strain and resultant back injuries in nurses working in geriatric care. The results showed a clear pattern of declining incidence of nurses' back pain for the nurses trained in Manutention and increasing incidence in the other two homes. These findings approached significance with a probability of < 0.1. Of those respondents who indicated a decrease in pain during the twelve month research period, all attributed it to their training. Ninety four percent of respondents who received training agreed it made their manual handling job easier. The observation method used was not sensitive enough to evaluate the multiple movements involved in a patient transfer. A supplementary controlled study was performed using videotaping and the Ovako Working Assessment System (OWAS). Manutention lifts were rated significantly better than non-Manutention on the critical variable of working posture (p < 0.01) and observed effort (p < 0.05). Accident statistics on patient handling did not show decreased injury rates at twelve months. The difficulties of controlling variables in the workplace and of the measurement of complex handling tasks were limitations of this study.     

Use of manual speed alerting and cruise control devices by car drivers

A number of in-vehicle technologies have been developed that have significant potential to reduce the incidence and severity of speed-related crashes. Two of the most widely implemented of these are conventional cruise control and manual speed alerting devices. However, almost nothing is known about the extent to which drivers use these devices and whether they are effective in helping drivers reduce speeding. This study assessed the use, acceptability and effectiveness in reducing speeding of manual speed alerting and cruise control devices to a sample of drivers from the Australian state of New South Wales. Four focus groups were conducted; two in Sydney (metropolitan) and two in Wagga Wagga (rural), involving 31 drivers aged 25–49 years, who were either users or non-users of the devices. The participants held positive attitudes towards manual speed alerting and cruise control systems and felt that these devices are generally effective in helping them to control and maintain their speed. However, the rural participants use cruise control more regularly than metropolitan participants, while the metropolitan participants reported that they use their speed alerting system more than rural participants. Preliminary recommendations deriving from the research are made.     

Occupational health and safety issues in the informal economic segment of Pakistan: a survey of construction sites

This research covers the current status of occupational health and safety (OHS)-related practices in the informal construction segment of Pakistan. Data were collected, through interviews, from 316 construction sites employing 3577 workers. The results of the study reveal that both employers and workers lack knowledge of OHS laws/standards and no practices of this nature are enacted at these construction sites. Alarmingly, work-related accidents, whenever they happen, are not given due attention and there is no formal injury-report system. The informal construction industry employs a huge portion of the informal workforce, and lack of OHS happens at tremendous human cost. These research findings may thus play their role in strengthening the case for reforms in the sector. This study, if properly utilized, may also enable employers of the sector by increasing their knowledge about OHS practices and, as a result, trying to offer safer environments for their workers.     

Small enterprises – Accountants as occupational health and safety intermediaries

Small enterprises face serious occupational health and safety challenges. The occupational risks are high and resources to control the risks are low. There is an ongoing search for ways that authorities and professional bodies can efficiently reach out to small enterprises with preventive measures. It has been suggested in the literature that accountants could act as intermediaries on health and safety. A pilot project was carried out in Denmark to test this possibility. State-authorized accountants were invited to training seminars to give them the necessary health and safety knowledge to provide advice to small enterprises. 164 accountants participated in the seminars and 74 accountants replied to a follow up questionnaire about their experience of advising their small enterprise clients about health and safety. Most of the accountants had actually given health and safety advice and for most of them it was a positive experience. However, they also faced constraints due to the relatively minor role health and safety played in their agendas with their clients and their own limited knowledge about health and safety even after taking part in the training seminars. This study concludes that it is possible for accountants to act as health and safety intermediaries, but that institutional support for the training activities is important to secure a broader application of this approach.     

Implementing risk management to reduce injuries in the U.S. Fire Service

IntroductionRisk management, a proactive process to identify and mitigate potential injury risks and implement control strategies, was used to reduce the risk of occupational injury in a fire department. The objective of this research was to study the implementation of the risk management process for future replication. A second objective was to document changes in fire personnel's knowledge, attitudes, and behaviors related to the selected control strategies that were implemented as part of the risk management process.MethodA number of control strategies identified through the risk management process were implemented over a 2-year period beginning in January 2011. Approximately 450 fire personnel completed each of the three cross-sectional surveys that were administered throughout the implementation periods. Fire personnel were asked about their awareness, knowledge, and use of the control strategies.ResultsFire personnel were generally aware of the control strategies that were implemented. Visual reminders (e.g., signage) were noted as effective by fire personnel who noticed them. Barriers to use of specific control strategies such as new procedures on the fireground or new lifting equipment for patient transfer included lack of knowledge of the new protocols, lack of awareness/access to/availability of the new equipment, and limited training on its use. Implementation challenges were noted, which limited self-reported adherence to the control strategies.ConclusionsFire personnel generally recognized the potential for various control strategies to manage risk and improve their health and safety; however, implementation challenges limited the effectiveness of certain control strategies. The study findings support the importance of effective implementation to achieve the desired impacts of control strategies for improving health and safety.Practical applicationsEmployees must be aware of, have knowledge about, and receive training in safety and health interventions in order to adopt desired behaviors.     

Change in frontline supervisors’ safety leadership practices after participating in a leadership training program: Does company size matter?

Introduction: The majority of construction companies are small businesses and small business often lack the resources needed to ensure that their supervisors have the safety leadership skills to build and maintain a strong jobsite safety climate. The Foundations for Safety Leadership (FSL) training program was designed to provide frontline leaders in all sized companies with safety leadership skills. This paper examines the impact of the FSL training by size of business. Methods: Leaders, defined as foremen or other frontline supervisors, from small, medium, and large construction companies were recruited to participate in a study to evaluate the degree to which the FSL changed their understanding and use of the leadership skills, safety practices and crew reporting of safety-related conditions. We used linear mixed modeling methods to analyze pre-post training survey data. Results: Prior to the training, leaders from small and medium sized companies reported using safety leadership skills less frequently than those from large ones. After the training, regardless of business size, we observed that the FSL training improved leaders understanding of safety leadership skills from immediately before to immediately after the training. Additionally, leaders reported greater use of safety leadership skills, safety practices, and crew reporting of safety-related conditions from before to two-weeks after the training. However, those from small and medium sized companies reported the greatest improvement in their use of safety leadership skills. Conclusions: The FSL training improves safety leadership outcomes regardless of the size company for which the leader worked. However, the FSL may be even more effective at improving the safety leadership skills of leaders working for smaller sized construction companies or those with lower baseline levels of safety leadership skills. Practical applications: The majority of construction companies employ a small number of employees and therefore may not have the resources to provide their frontline leaders with the leadership training they need to be effective leaders who can create a strong jobsite safety climate. The Foundations for Safety Leadership (FSL) training can help fill this gap.     

Using online databases to find journal articles on injury prevention and safety promotion topics: How do SafetyLit subscribers use other databases?

BackgroundA thorough search of the scholarly literature is an important part of any project. Although there are ethical and scientific reasons to justify the effort required to perform an exhaustive search, we hypothesize that many searchers do not use a sufficient number of databases nor do they use the query focusing techniques necessary to perform a comprehensive search.DesignSubscribers (approximately 19,000 people) to the SafetyLit email update, a weekly listing of recently published research on injury prevention and safety promotion, were surveyed to learn about their performance and knowledge of several key search behaviors necessary for conducting an exhaustive literature search.ResultsOver 90% of respondents perform searches of online databases and, although few have had any training in database use, they always or usually perform the search themselves. They reported performing searches using a wide variety of online bibliographic databases but only 10.3% queried two or more databases the last time they searched. Respondents’ assessment of their own knowledge and skills at searching a database had little to do with the amount of training they have received in the use of the database.ConclusionMost users self-limit the information they gather to that from one or two professional disciplines. Conducting a literature search using only one or two familiar sources can lead to a failure to access essential information published by researchers in parallel fields.

Leadership skills for strengthening jobsite safety climate

Introduction: Construction foremen may lack the leadership skills needed to create a strong jobsite safety climate. Many construction companies address this by sending their lead workers to the OSHA 30-h course; however the course does not include a leadership training module. This article describes the development and pilot testing of such a module and evaluation surveys designed to address this training gap. Methods: A 17-member curriculum development team, numerous subject matter experts, and an instructional design company helped us develop a comprehensive set of teaching resources and a set of survey instruments for evaluating the materials' effectiveness on improving safety leadership and safety climate. All materials and surveys were pilot tested with representative members of the target population. Results: Pilot surveys showed high reliability and data collected on the resulting Foundations for Safety Leadership (FSL) module indicated that the majority of foremen thought the training was helpful or valuable, particularly the discussion questions. The majority said they intended to use the skills on the jobsite. With the exception of the role-play activities, the trainers rated highly all other components, especially the videos and discussion questions. Modifications were made to the training materials and surveys based on pilot test findings. The most important result of the development and pilot testing efforts is that the OSHA Training Institute (OTI) included the FSL as an elective in the OSHA 30-h course. Conclusions: The FSL module fills a needed skills gap by providing safety leadership training to all foremen who might otherwise not have access to it through their company or union. The continued success of the FSL training will be ensured by dissemination via the OSHA 30-h course, an established nationwide safety training program. Practical applications: The FSL training module has already been widely accepted by the construction industry as a useful approach for providing construction foremen/See new abstract lead workers with the knowledge and skills they need to become more effective jobsite safety leaders.     

Knowledge, attitude, and practice of Nigerian commercial motorcyclists in the use of crash helmet and other safety measures

OBJECTIVE: This study was designed to evaluate the knowledge, attitude, and practice of some commercial motorcyclists in Nigeria in the use of crash helmet and other cycling safety measures. METHODS: At randomly selected commercial motorcycle parks from two South Western Nigerian locations (Lagos and Ile-Ife), we obtained verbal consent from commercial motorcyclists (randomly selected) and thereafter administered structured questionnaires to consenting motorcyclists. The questionnaire sought to know the respondents' biodata (age, gender, and educational attainment inclusive), cycling background, and experience (trainer, duration of training and cycling, and history of crashes). Furthermore, risk factors and practices like alcoholism, maintenance history of the motorcycle, maximum number of pillion passengers carried, and use of crash helmet were elicited. Respondents' knowledge of available safety measures was also investigated. Data was entered into an IBM compatible computer and analyzed using the SPSS 11.0 statistical software. Statistical significance was inferred at p value<0.05. RESULTS: There were 224 male respondents aged 15-58 years. Their peak age was 25-29 years and mean 35.1+/-8.9 years; 8.4% had no formal education; 10.3% received formal training but the majority were either trained by self (35.5%) or an acquaintance (34.6%). Training lasted相似文献   

Harmful postures and musculoskeletal symptoms among sanitation workers of a fish processing factory in ghana: a preliminary investigation.

This study investigated musculoskeletal symptoms among sanitation workers of a fish-processing factory. The methods used included administration of a questionnaire, walk through observation, interview, task analysis and future workshop. All 27 male participants answered and submitted their questionnaires. Of the 11 operations identified, all except one was considered safe. Bent back, bent legs, and heavy manual handling were observed to impose intolerable health risk on participants. This corresponds with questionnaire results in which musculoskeletal symptoms were mostly prevalent in the neck, the shoulder, the low back, the wrists/hands and the upper back regions. Poor psychosocial complaints were also made on the job. There was no significant correlation (p < .05) between musculoskeletal symptoms and age, working hours and length of service. Neither was any significant correlation observed (p < .05) between psychosocial work factors and musculoskeletal symptoms. Recommendations such as task redesign to eliminate high-risk elements in operations, workplace changes and worker training were suggested.     

Factors that influence the use of safe patient transfer technique in home care service

The aim of this pilot study was to explore whether home care service personnel used knowledge and skills in transfer technique in their daily work; knowledge and skills gained by participating in training programmes, and to identify factors that may hinder and support their use. Focus group interviews were held with 2 home care service groups in 2 Swedish towns. Individual interviews were conducted with the personnel's managers, unit leaders and safety representatives. Qualitative content analysis was used. The findings revealed that the personnel tried to use their knowledge and skills. However, there were both hindering and supporting factors for the use of safe work technique. The findings indicate that training programmes in transfer technique should not be implemented as isolated actions without considering the physical environment, the wishes of persons receiving care and their relatives, the work organisation, the safety culture and the role of managers.     

Equipment failures and their contribution to industrial incidents and accidents in the manufacturing industry

Accidental events in manufacturing industries can be caused by many factors, including work methods, lack of training, equipment design, maintenance and reliability. This study is aimed at determining the contribution of failures of commonly used industrial equipment, such as machines, tools and material handling equipment, to the chain of causality of industrial accidents and incidents. Based on a case study which aimed at the analysis of an existing pulp and paper company's accident database, this paper examines the number, type and gravity of the failures involved in these events and their causes. Results from this study show that equipment failures had a major effect on the number and severity of accidents accounted for in the database: 272 out of 773 accidental events were related to equipment failure, where 13 of them had direct human consequences. Failures that contributed directly or indirectly to these events are analyzed.     

Small Business Owners’ Knowledge of Their Occupational Health and Safety (OHS) Legislative Responsibilities

This article reports the results of a study investigating the nature and extent of small manufacturing business owners’ knowledge of Occupational Health and Safety (OHS) issues. Interviews were conducted with 33 owners of small manufacturing businesses in Sydney, Australia. Results showed that whereas the majority of owners had basic awareness of the existence of OHS legislation, they were often unaware about the extent of their legal OHS responsibilities. Owners were found to have minimal OHS training and practical OHS expertise. Lack of appropriate industry specific OHS information was found to be a major factor that inhibited the owners’ ability to deal with OHS issues effectively.     

Mechanical Equipment Injuries in Small Manufacturing Businesses. Knowledge,Behavioral, and Management Issues

This paper presents findings from an extensive study intofactors that impact upon the high rate of injuries due to mechanical equipment, especially in small manufacturing firms. Issues relating to knowledge of health and safety issues and to management practices have been shown to be extremely important with regards to safety in smaii businesses. Knowledge and awareness of hazards were found to be relatively low and few respondents, especially managers, had received adequate safety training. Managers did not regard the identification and control of risks as a priority. Workplaces generally lacked effective safety management procedures such as safety rules and regulations, procedures for recording and learning from accidents, and clearly defined responsibilities for safety. Some issues requiring further investigation, and some recommendations for improving safety in small businesses, are presented.     

Epidemiological and biomechanical evaluation of airline baggage handling

Objectives. Musculoskeletal disorders (MSDs) are prevalent among airline baggage handlers due to manual materials handling. In this study, the Nordic musculoskeletal questionnaire (NMQ), the revised National Institute for Occupational Safety and Health (NIOSH) lifting equation, and the University of Michigan 3D Static Strength Prediction Program? (3DSSPP) were used to analyze MSDs among baggage handlers. Methods. The NMQ was filled out by 209 baggage handlers and 46 arbitrarily selected baggage handlers were evaluated using the NIOSH method and 3DSSPP. Results. The obtained results showed that the most common MSDs occurred in the lower back region. The next risky regions included knees, neck, and upper back, respectively. The NIOSH results confirmed that the subjects lifted loads heavier than the permitted limit and their lifting postures were inappropriate. The results of the 3DSSPP also indicated that compression forces exceeded the NIOSH limit in these awkward postures. Conclusions. Relying on this study, holding compulsory ergonomic lifting training courses could be proposed for workers and regulations adjusting an upper limit for maximum baggage weight must be also enacted in order to improve occupational health and prevent the prevalence of increasing MSDs.     

Lower back pain and its association with whole-body vibration and manual materials handling among commercial drivers in Sabah

A cross-sectional study was undertaken to determine the prevalence of lower back pain (LBP) and its association with whole-body vibration (WBV) and manual materials handling (MMH). We studied 110 commercial vehicle drivers using a self-administered questionnaire and the VI-400Pro human vibration monitor. Prevalence of LBP was 66.4%. The percentage of drivers who had frequent manual handling of heavy loads was 45.5% and those who handled heavy loads in awkward postures accounted for 86.4%. Daily vibration A(8) averaged on the z axis was 0.25 (0.06) m·s^?2 and at vector sum was 0.29 (0.07) m·s^?2. Daily vibration exposures on the z axis, frequent manual handling of heavy loads and awkward posture during MMH were significantly associated with LBP. Drivers who are exposed to WBV and frequently handle heavy loads manually and with awkward postures probably have more LBP than drivers who are exposed to only one of these risk factors.     

The effects of ergonomics training on the knowledge, attitudes, and practices of teleworkers

PROBLEM: The rapid growth of teleworking has raised several social and legal issues regarding an employer's responsibility for the safety of an employee's home office. In this paper, researchers discuss the need for safety training for teleworkers and the effectiveness of a home office ergonomics training program. METHOD: Study participants (N = 50) were randomly assigned into a treatment or control group. The treatment group completed the ergonomics training and a pre- and posttest. The control group completed the pre- and posttests without training. RESULTS: The study demonstrated the need for teleworker ergonomics training. More than 85% of participants had not received teleworker training before, and 44% had experienced pain or discomfort while teleworking. Participants who completed the training significantly improved their scores on knowledge, attitude, and practices subtests. In a follow-up survey, participants indicated that they had made ergonomic changes to their offices based on the training. Several participants indicated that the pain or discomfort that they had been experiencing was eliminated or reduced as a result of the training.     

Occupational accident: An example of fatalistic beliefs among medical waste workers in Bangladesh

This study was conducted to see whether fatalism is an important factor in explaining occupational accidents among medical waste operatives in Dhaka, Bangladesh. Data were collected using a variety of qualitative techniques and included observation, formal and informal dialogue. Sampling strategies included formal representative sampling, purposive and authoritative sampling. Employers did not supply PPE or offer training to their staff. Most workers (73%) did not wear PPE regularly, and a further 18% wore only insufficient PPE. Consequently, most waste workers (95%) reported that they had experienced occupational accidents, mostly (75%) from used needles and other sharps. These observations were associated with fatalistic beliefs among the participants, both managers and employees, who attributed these events to “fate” reflecting their perceived lack of control over such accidents. This study reveals many examples of a lack of organisational awareness that can occur within a culture of fatalism.
