Worksite accommodations for manufacturing employees in a pipe fabrication facility

Through the use of professional experience and case studies, this article will examine the occurrence of injuries and work site accommodations for employees in a pipe fabrication facility. Specific means early injury intervention and environment or ergonomic controls can benefit both worker and employer regarding return-to-work transition will be discussed. Three case studies will be cited to specifically describe means a condition of events may contribute to a successful return-to-work outcome.     

An on-site ergonomic program: A model for industry

Work related conditions caused by overexertion or repeated trauma affect millions of American workers. These conditions can result in time off from work, decreased productivity, and high financial costs, not to mention impairment of the worker. According to the Occupational Safety and Health Act (OSHAct) of 1970 [26], employers are required to provide hazard free workplaces for their employees. Fortunately resources exist to help employers set up on-site ergonomic programs to reduce the hazards that contribute to cumulative trauma disorders (CTDs) or other injuries. Companies that have implemented comprehensive ergonomic programs have reported benefits, most significantly, decreased injuries, and cost savings. A model is described for industry on starting and managing a successful on-site ergonomic program.     

Workplace aesthetics: Impact of environments upon employee health?

Associations between self-reported need for aesthetic improvements in the workplace and the need for ergonomic improvement and health factors were investigated to determine the possible impact of aesthetic needs on job performance. The need for aesthetic improvements were compared with the need for ergonomic improvements. All employees at a Swedish broadcasting company were invited to participate in this cross sectional study. Of those who fulfilled the inclusion criteria the participation rate was 74% (1961/2641). Demographic data was obtained from company files and pre-validated questionnaire was used for data collections from the participants. additional questions on needs for improvement were developed, tested for repeatability, and demonstrated to be within acceptable limits. Differences between 'high rank' and 'low rank' aesthetic needs and ergonomic needs were correlated to set ups of demographic, work environmental and organisational and health variables.The perceived needs for aesthetic and ergonomic improvements showed significantly different distributions (p<0.001). Aesthetic needs were more frequently reported than ergonomic needs. There was no significant gender related difference in response distribution of aesthetic or ergonomic needs, whereas differences between occupational groups were shown (0.006 and 0.003). 'High rank' needs for aesthetic improvement were associated to psychologically demanding work, negative work stress, sleep disturbances, problems at work, musculoskeletal pain and lower age. Gender and physical training did not differ between 'high and low rank' responders regarding neither aesthetic nor ergonomic needs. Sick leave was stronger related to ergonomics. The independently tested associations with aesthetic needs were similar to, but fewer than those for ergonomic needs with regard to the variable set ups. Sixteen studied factors out of 24, showed significant difference between 'high and low rank' aesthetic needs, and 21/24 of ergonomic needs, independently tested. The study results show a relation between work place aesthetics and health and well-being. Future work health promotion and prevention may benefit from the inclusion of an assessment of workplace aesthetics.     

Participatory ergonomic intervention for prevention of low back pain: assembly line redesign case

This paper gives an overview of a participatory ergonomic intervention aimed at reducing low back pain cases in the dispatch department of a catalogue and e-commerce retail company. Based on the findings of the ergonomic analysis and design committee, the company's own employees redesigned the assembly line's layout. As a result of these changes two job tasks that involved manual material handling of boxes, identified by the revised NIOSH equation as posing an increased risk for lifting-related low back pain, were totally eliminated, and the employees responsible for moving boxes from the end of the assembly line to pallets on the ground were given more control over their jobs, and these jobs were also enriched with a new, less heavy task. These results demonstrate that participatory ergonomic interventions are a viable and effective strategy to reduce the exposure to work-related physical and psychosocial risk factors for low back pain.     

Managing ergonomics in the development of rotation between workstations in the automotive industry. A balance between health and traceability of tasks

Abstract When the subject rotation between workstations (job rotation) is inside the organizations it's seemed that technically there are lots of restrictions to the development of an adequate system of rotation. We went from the need for an advanced ergonomic study and even possible restrictions of versatility and training of employees. The implementation of the ideal system of rotation passes through stages of development and research ergonomic study of the level of employee versatility, awareness and discussion with employees, implementation of the proposed system, feedback and audits for maintenance of the ideal sequence and time of rotation. For the success of the project there is a need for multidisciplinary involvement in the areas of manufacturing engineering, industrial engineering, human resources, medical services and manufacturing. Rotation between the tasks may mean that a worker should conduct two or more different activities in different parts of the day (ie. change between activity A and activity B "between 1 hours and 2 hours interval). An important consideration is to ensure that different activities do not present the same ergonomic risk for the same body part. The tracing of the execution of the activity is an important factor for production processes. Thus it is possible to conduct appropriate levels of training for employees and ensure safe and sustainable processes in terms of workers' health, productivity and quality.     

A single-subject design of ergonomic intervention effectiveness for university employees in a new facility

As clinicians are searching for evidence to support their practice interventions, it is sometimes hard to find the "real-world" studies that incorporate the complexities of actual practice. Following calls in the public health, nursing and medical literature for clinicians to participate in practice-based evidence, this pilot study explores the effectiveness of a single-subject design for practice-based evidence. Twenty-five "well" university employees participated in an ergonomic intervention over the course of one academic semester that consisted of a 15 min ergonomic intake session, a 45 min group hands-on ergonomic educational session and a 15 min individual ergonomic consult in their offices. Participants were sent postural comfort surveys weekly and their subjective ratings were analyzed to determine the effectiveness of the intervention to decrease their perceived postural discomfort at a computer work station. Twenty-one of the twenty-five participants reported an improvement in postural comfort over the course of the study. This pilot study suggests that further investigation needs to be conducted to determine the effectiveness of hands-on ergonomic education and consultation for well populations working at computer workstations.     

The ergonomics analysis of work: a case study in a experimental farm

This work presents the initial steps of ergonomic analysis of industrial activities, which are being held in the premises of an Agricultural Experimental farm belonging to an institution of higher education. The methods employed in the initial step was confined to desk research, its purpose was to know the demographic profile and understand organizational structure followed by systematic observations in workplaces using semi-structured interviews and a questionnaire of perception to operators. The presentation of the results will provide a summary of the analysis of activity sectors visited, understanding the biomechanical efforts entered (posture and strength), as well as the evaluation according to the perception of officials to respect the constraints, ambience and suggestions. It was noted that 90% of employees surveyed feel some kind of discomfort. It also highlights the age factor of this questionnaire, in which the majority (90%) is above 40 years old, and this fact confirms and reinforces the appearance or accumulation of injuries among the employers. At this stage there was no intention to deploy improvements, but create assumptions and guide future intervention actions that can be performed.     

BASE als Programm zur Pr?vention von (Rücken-)Beschwerden in der betrieblichen Gesundheitsf?rderung

Common occupational health problems, especially low back pain, are associated with physical demands of work, like lifting heavy weights. The study examined a multidimensional methodological approach (BASE) to reduce physical stresses in a logistic company in three stages: (1) theoretical background and implementation of the program, (2) evaluation of outcome-effects of a box lifting training (10 weeks) and (3) learning and lasting effects of workers?? knowledge and behaviour with regard to ergonomic box lifting. Video analysis and questionnaires were used for breakdown analysis. Stage (2) and (3) collected intervention effects with a controlled pre?\post test design (N?=?41 males; 37.8?±?10.8 y.). The breakdown analysis revealed low back pain (65?%) as a result of repeated manual lifting processes. Participants of the intervention showed a more ergonomic movement initiated by a more functional cognitive representation in long term memory. We suggest that especially this group of employees, with little motivation to participate in health promotion, benefit from the whole methodological approach of the BASE-program.     

Ergonomics in a hospital and a university setting: The effect of worksite analysis on upper extremity work-related musculoskeletal disorders

OBJECTIVES: The purpose of this study was to determine whether individuals with work-related injuries receiving worksite analysis would have less lost workdays than individuals not receiving worksite analysis. Therapeutic management of work-related injuries in a hospital and a university setting were also compared. STUDY DESIGN: Over a one-year period, employees who sustained an upper extremity work-related injury were issued questionnaires regarding their injury, treatment, functional status and pain level. Participants were divided into three groups: group 1 consisted of hospital employees (N=14) who underwent worksite analysis, group 2 included university employees (N=15) who underwent worksite analysis whereas group~3 included university employees (N=14) who underwent no analysis. RESULTS: All groups were similar in demographics, functional status, and pain level. Satisfaction with the worksite analysis was similar for groups one and two. CONCLUSION: A pattern of less absenteeism but greater modified duty days was associated with those individuals undergoing worksite analysis.     

Workplace aesthetics: impact of environments upon employee health as compared to ergonomics

Associations between self-reported needs for aesthetic and ergonomic improvements were studied to analyse a possible impact of aesthetic needs on job performance as compared to ergonomic needs in 11 occupational groups. Employees at Swedish broadcasting company were invited to participate in a cross sectional study. 74% (n=1961/2641) fulfilled the inclusion criteria. Demographic data from company files and a pre-validated questionnaire were used. 'High rank' and 'low rank' aesthetic and ergonomic needs were compared. The perceived needs for aesthetic and ergonomic improvements showed significantly different distributions (p<0.001). Aesthetic needs were more frequently reported. No gender related differences were observed. Differences between occupational groups were shown (p=0.006, 0.003).'High rank' needs for aesthetic and ergonomic improvements were similarly associated to psychological demands, stress, pain and age. 16/24 factors showed significant differences between 'high and low rank' aesthetic needs, whereas 21/24 between ergonomic needs. Sick leave was stronger related to ergonomics. The study results show a relation between not only work place ergonomics but also work place aesthetics to health and well-being. Future work health promotion and prevention may benefit from the inclusion of workplace aesthetics.     

Participatory ergonomics intervention in a sterile processing center: a case study

The following case study describes an ergonomics intervention program, designed and implemented by an occupational therapist (OT), which included principles of participatory ergonomics, had full support of management and administration, and addressed the work, worker, and environment. The ergonomics program took place in the Sterile Processing Center (SPC) of a 398 bed, mid-western hospital. The SPC was responsible for the collection, sterilization, and reassembling of hospital surgical equipment. The 30 employees of the SPC were vulnerable to injury, having experienced 19 in only two years (of the 19 injuries, 9 were WMSD or ergonomics-related injuries). Over a two and a half year period, the OT and SPC manager conducted ergonomic evaluations, implemented employee training, designed a new SPC department, and modified work processes and equipment. In the year following the training and changes, the SPC staff experienced no injuries. Because of it's success, the program is continuing on a quarterly basis to ensure new problems are addressed quickly, new processes or equipment are evaluated, and new staff are properly trained.     

Care giving and nursing, work conditions and Humanitude®

Increased lifespan in western societies causes the increase of hospitalization in the old age, notably for patient showing forms of dementia including Altzheimer disease. These patients relate poorly to care givers and nurses, and cases of maltreatment have repeatedly been reported. To prevent abuse and increase patient's quality of life, Gineste and Pelissier (2007) proposed a philosophy of care based on the Humanitude? concept. Acknowledging that being human is being vertical and related to other humans, the pillars of Humanitude? are gaze, touch, talk, and standing. These modes of relation are systematically developed in care giving techniques derived from the concept. After several studies in geriatric hospitals, to assess psychosocial and ergonomic aspects of work, we present an analysis of the gap between the logic of human care and the logic of hospital organization, impacting employees work conditions and psychological welfare. Care giving is not only a "one to one" relation with the patient but needs to be integrated in the whole organization. Psychologists and ergonomists should be instrumental in defining the project and the organization linking human care giving towards the patients and better work conditions for healthcare employees.     

Ergonomic recommendations and their impact on child care workers' health

The purpose of this study was to determine the impact ergonomics has had on the occurrence of musculoskeletal symptoms and injuries among child care workers in Wisconsin using a Classroom and Work Methods Survey developed for this investigation. Information on perceived need for and knowledge of ergonomic interventions, the extent to which ergonomic interventions had been introduced to child care settings, and barriers to implementation of ergonomic recommendations was gathered. Two hundred and fifty-eight respondents completed the survey. The majority of respondents was aware of most (18 of 20) of the recommended ergonomic interventions for child care centers and did not perceive a need to make ergonomic changes. Although the majority of respondents had implemented 15 out of the 20 recommendations, they were currently experiencing musculoskeletal pain while performing their jobs. The results of this study highlight the need for further analysis of specific child care tasks and identification of more effective methods to reduce the risk for musculoskeletal pain and injuries.     

Ergonomic considerations in school environments - the need for widening the scope

Behaviour patterns specific to children pose them at greater risk of environmental hazards than adults. Ergonomics is the science of matching human interaction with the proximate environment. Conventionally ergonomic principles were applied on adult work places to ensure safety of the working environment. With emerging scientific evidence, school environments are being a focus to apply ergonomic principles. Children spend more time within schools during critical developmental stages of their life. Everybody feels that the schools are safe places, but they are not. A multitude of ergonomic hazards have been identified in school settings. Widespread mismatches between anthropometry and school furniture, heavy schoolbag carriage and unhealthy bag behaviour are significant. Negative effects range from general tiredness, musculoskeletal pains, spinal deviations, shoulder level shifts, injuries and psychological disturbances. There are fragmented efforts to widen ergonomic concepts to health care professionals and other stakeholders of child health. Addressing ergonomic issues will ensure that children, the future productive generation contributing to economic growth and development of a country, are provided with opportunities in a healthy environment. This paper emphasizes the need for a concerted effort on widening the scope of ergonomics to cater for the evolving demand.     

Needs of ergonomic design at control units in production industries

During the last decades, an increasing use of innovative technologies in manufacturing areas was monitored. A huge amount of physical workload was replaced by the change from conventional machine tools to computer-controlled units. CNC systems spread in current production processes. Because of this, machine operators today mostly have an observational function. This caused increasing of static work (e.g., standing, sitting) and cognitive demands (e.g., process observation). Machine operators have a high responsibility, because mistakes may lead to human injuries as well as to product losses - and in consequence may lead to high monetary losses (for the company) as well. Being usable often means for a CNC machine being efficient. An intuitive usability and an ergonomic organization of CNC workplaces can be an essential basis to reduce the risk of failures in operation as well as physical complaints (e.g. pain or diseases because of bad body posture during work). In contrast to conventional machines, CNC machines are equipped both with hardware and software. An intuitive and clear-sighted operating of CNC systems is a requirement for quick learning of new systems. Within this study, a survey was carried out among trainees learning the operation of CNC machines.     

A controlled case study of supervisor training to optimize response to injury in the food processing industry

The role of supervisors to aid injured workers, access health care, and provide reasonable accommodation may prevent prolonged disability among workers reporting musculoskeletal pain. Although supervisor training has been a common element of broad-based ergonomic interventions to prevent injuries, the impact of supervisor training alone to improve injury response has not been studied. In a controlled design, 11 supervisors in an intervention group and 12 supervisors in a delayed intervention control group from the same plant were provided a 4-hour training workshop. The workshop emphasized communication skills and ergonomic accommodation for workers reporting injuries or health concerns. Workers' compensation claims data in the 7 months before and after the workshop showed a 47% reduction in new claims and an 18% reduction in active lost-time claims versus 27% and 7%, respectively, in the control group. Improving the response of frontline supervisors to employees' work-related health and safety concerns may produce sustainable reductions in injury claims and disability costs.     

What makes age diverse teams effective? Results from a six-year research program

Based on a new model of productivity in age diverse tams, findings from a six-year research program are reported in which data from more than 745 natural teams with 8,848 employees in three different fields (car production, administrative work, financial services) were collected. Moreover, central assumptions of this model were tested with a representative survey of the German workforce (N = 2,000). Results support both significant advantages and disadvantages for age-mixed teams. Based on the findings, the following preconditions for the effectiveness of age diverse teams are identified: high task complexity, low salience and high appreciation of age diversity, a positive team climate, low age-discrimination, ergonomic design of work places, and the use of age differentiated leadership. Based on these insights, we developed a new training for supervisors, which addresses the aforementioned aspects and seeks to improve team performance and health of team members. It was found that the training reduces age stereotypes, team conflicts and enhances innovation. Thus, we can conclude that effective interventions for a successful integration of elderly employees in work groups are available and that combinations of measures that address ergonomic design issues, team composition and leadership are to be strongly recommended for practice.     

Women, work and childcare: where have we been? Where are we going?

Working mothers who simultaneously manage a job, raise children, and maintain a home may find the endeavor to be physically and emotionally challenging. By means of a case study, this paper explores the impact of work-related injury on one mother's ability to meet the physical demands of childcare and homemaking tasks without jeopardizing her physical recovery or job security. Following a musculoskeletal injury at work, the subject received traditional occupational therapy intervention as well as specific education regarding ergonomic childcare techniques. Her ability to perform routine homemaking and childcare tasks was assessed prior to and following treatment using the ErgoMomics MOMS (Measure of Musculoskeletal Symptoms) survey. The case study suggests that educating mothers in ergonomic techniques related to vocational as well as avocational tasks may be beneficial in helping them manage the dual demands of family life and career. Additional informal interviews were conducted with twelve mothers, ages thirty-five to sixty-eight, in order to frame the case study within a wider historical perspective concerning the role of work in women's lives.
