abstract: The true number of food borne illness occurrences that stem from the home is largely unknown, but researchers believe the number is much greater than represented in national data. The focus on food safety has generally been directed at food service establishments, which have made great strides at improving the methods of how their food is prepared. However, that same drive for proper food safety education is lacking in home kitchens, where the majority of food is prepared. Young adults are among some of the riskiest food preparers, and limited research and education methods have been tested on this vulnerable population. This study examined the effect of a basic food safety intervention on consumer food safety knowledge in young adults in the United States (U.S.) over a week period. The study had a pre/post survey design, where participants answered a survey, watched a short 10-minute video, and then recompleted the same survey a week later. Ninety-one participants age 18-29 years completed the initial food safety knowledge questionnaire. Twenty-six of those participants completed both the pre- and post-intervention food safety knowledge questionnaires. A paired t-test was used to analyze changes in questionnaire scores pre/post intervention. The majority of participants were female (78.9%), Arizona State University (ASU) students (78.0%), did not have any formal food safety education (58.2%), prepared a minimum of one meal per week from home (96.7%), and had completed 0-1 college nutrition courses (64.8%). The average overall score for all participants who completed the initial questionnaire was 62.6%. For those that took both the initial questionnaire and the follow up questionnaire (n=26), their scores shifted from 66.8% to 65.5% after the intervention. Scores increased significantly only for one question post-intervention: 38.5% (n=10) to 53.8% (n=14) for the safest method for cooling a large pot of hot soup (p = 0.050). This was the first study of its kind to test a video intervention in attempts to increase food safety knowledge in young adults, and additional studies must be done to solidify the results of this study. Other means of education should be explored as well to determine the best way of reaching this population and others. / Dissertation/Thesis / Masters Thesis Nutrition 2019

Thesis (MBA.) --University of Limpopo, 2008 / Chemicals are found to be enormously dangerous on the health and safety criteria. In academic laboratories, chemical safety has always been a major concern. Safety risks are either not perceived at all, or perceived to be less dangerous than what they actually are. The climate of safety in any organization consists of employees’ attitudes towards, and perceptions of safety behaviour. In academic departments, safety is influenced by factors such as the organisational environment, management attitude and commitment, the nature of the job or task, and the personal attributes of the individual. This study is concerned with safety climate and chemical management practices in academic departments. More specifically, it investigates the safety perceptions, attitudes, and chemical management behaviours of university employees. It represents the empirical results of a questionnaire survey administered in a university department and direct observations of safe and unsafe chemical management behaviours, targeting employees who work with chemicals. Based upon the survey analysis results, this study demonstrates that employees in the academic departments under study have a good degree of risk awareness and a relatively high degree of safety consciousness. The results also reveal employees’ intentional unsafe chemical management behaviours. Further, it was found, empirically, that overall employees’ intentional unsafe behaviours seem to be best explained by employees’ perceptions of management attitude and commitment to safety, social and physical work environment, priority for safety, as well as their perception of the risk they are generally exposed to in their work environment. The study, thus, establishes that perceptions of management attitudes and actions have a direct effect on employees’ behaviour. There is a positive correlation between workers’ safety climate and chemical management safe behaviour in academic departments.

Background: The burden of fatal and non-fatal injury for the New Zealand construction industry is larger than most other industrial sectors. Injury preventions efforts for construction have however been hampered because of insufficient, industry-specific, surveillance data that is essential for the effective targeting and evaluation of interventions. Aim: This thesis aimed to describe and test a feasible framework of Injury Surveillance for the New Zealand construction industry. Accordingly, the specific objectives to accomplish this aim were: To identify an optimal surveillance dataset for New Zealand construction injuries; To assess potential sources of data and collection methods; To describe an ideal study design for undertaking injury surveillance; To implement an operational design based on industry stakeholder input; To undertake and evaluate an injury surveillance trial; and To suggest how a viable surveillance system could be permanently established. Method: A trial injury surveillance system was developed by identifying known construction injury risk factors from the literature, reviewing the data collection practices of the New Zealand industry and other potential data sources and consulting with industry stakeholders about the most feasible collection methodology. This surveillance framework was then tested by combining national data from routine Government sources and data from 3 construction companies that employed approximately 720 workers between them. National construction injury data was obtained from the Accident Compensation Corporation, the Department of Labour and the Injury Information Manager. The trial Surveillance System was then evaluated in terms of its ability to collect the full range of an optimal dataset, the quality and completeness of information actually collected, the ability to identify and monitor injury priorities for the industry, and the future viability and acceptability of this surveillance design to the industry. Results: A total of 468 medically treated injuries were recorded by the participating companies, with 15 (3.2%) considered to be Serious Harm injuries as defined by the Health and Safety in Employment Act. The level of data completeness across companies was especially low, with on average 18 out of 34 data fields (53%) completely unrecorded. The data from one company was sufficiently complete (i.e. 63% across all fields) to allow individual risk factor analyses to be conducted, whereas the absence of complete denominator data prevented the completion of the same analyses for the other two companies. Viewed overall, Government agency data was sufficiently detailed to estimate national longitudinal trends, injury agency and mechanism priorities for specific occupations and industry subsectors, and allowed a rudimentary evaluation of a national intervention programme. However, questions about data accuracy, completeness and under-reporting were raised for each of the Government data sources used. Conclusions: Using data entirely from Government sources appears to be the most immediately viable framework of Injury Surveillance for the New Zealand construction industry. As such, the relevant range of analyses demonstrated by this study should be continued, expanded and improved. In contrast, obtaining injury surveillance data from companies in the manner that was tested does not appear to feasible, given the difficulty in recruiting companies and the poor data completeness of those companies that did participate. However, the increased range of prevention targets identified by the company that did largely contribute data as intended, demonstrated that company surveillance had merit relative to existing procedures. Suggested steps toward implementing viable construction injury surveillance within New Zealand are outlined, including a recommendation to the industry�s Health and Safety organisation, SiteSafe, to investigate the most feasible data collection protocol for its members.

This thesis describes the development, application and evaluation of an OHS measurement tool incorporating positive performance indicators to measure OHS performance in Australia Post, a large multi-site postal organisation. Positive Performance Indicators (PPIs) are identified as systematically implemented measures of the management processes initiated to achieve strategic goals. A literature review indicated that there was widespread support for the use of PPIs to measure OHS performance, with proponents advocating their use to monitor and promote implementation of target OHS strategies, and to evaluate the effectiveness of these strategies by using PPIs in conjunction with outcome indicators. Despite this widespread support, there was little practical guidance published on the development or application of PPIs, nor was there empirical evidence validating the claims of advocates. A series of research projects was undertaken to firstly develop - then evaluate - a set of OHS self-assessment tools incorporating PPIs. These projects comprised: review of the Australia Post OHS strategic plan, as the basis for the development of PPIs to measure that plan; development of a set of paper-based self-assessment tools incorporating quantitative OHS PPIs to measure the local implementation of the OHS strategic plan; quasi-experimental pilot study of the use of the OHS PPI self-assessment tools by Postal Managers, to investigate the reliability and effectiveness of the OHS PPI process in monitoring and driving conformance of OHS management processes; experimental study of the use of the OHS PPI self-assessment tools by Postal Delivery Facility Managers, to validate and extend the findings of the pilot study; development of a web-based software application to facilitate OHS PPI data collection and reporting; and, the use of correlation statistics to study the relationship of OHS PPIs with OHS outcome measures, and to assess their role in evaluating the effectiveness of specific OHS strategies. The studies demonstrated that the OHS PPI self-assessment tool could be effectively used by local facility managers to assess and report their implementation of the OHS strategic plan. In addition, the OHS PPI self-assessment process proved to strongly improve the local implementation of those OHS management processes measured. The study further showed that the consistent attention to OHS management processes driven by the OHS PPI measurement process assisted in the achievement of impressive OHS outcome improvements. However, the study showed that the use of correlation statistics to link OHS PPIs with outcome measures to evaluate the effectiveness of OHS management strategies has only limited value. Limitations in both the OHS PPI and outcome measurement data and in the correlation statistics restrict the extent to which findings can be interpreted or that conclusive judgements concerning the effectiveness of strategies can be drawn. The thesis concludes with an account of Australia Post's experiences in integrating OHS PPIs into its OHS management system.

The study was conducted to evaluate the use and perceived effectiveness of occupational safety and health consultative services among Oregon corporations. The three types of consultative services examined: workers' compensation insurance; private; and Oregon Occupational Safety and Health. The research examined if corporations, categorized by corporation size, within the four high-risk industry classes used each of the three types of consultative services. The four high-risk industry classes included: agriculture; construction; manufacturing; and wood products. Based on the results of the study, fewer than one-half of the respondents reported they had used consultative services; however, two out of three respondents indicated they were aware that consultative services were available. Of the three types of consultative services, workers' compensation insurance consultative services were used most frequently. In contrast, private consultative services were used least frequently even though respondents were most aware of the availability of the services. Overall, small corporations, primarily from the agriculture industry class, used consultative services the least whereas large corporations were most likely to use consultative services. Almost half of all respondents, who were aware of the availability of the consultative services and indicated that they had not used or would not use these services in the future, reported that they believed these services were unnecessary for their corporation. In addition, over half of the respondents cited cost as a prohibitive factor in requesting private consultative services. Among those respondents who implemented the recommendations of occupational safety and health consultants, over 84 percent of the respondents felt that the recommendations were either very effective or somewhat effective for all three types of consultative services. Although this percentage of perceived effectiveness was high, the percentage of respondents who reported that consultative services were instrumental in loss reduction was considerably lower than the perceived effectiveness. This finding indicates that respondents' perceived effectiveness of occupational safety and health consultative services include more than loss reduction elements. Future studies need to discern what these additional elements include. / Graduation date: 2000

The purpose of this study was to investigate the safety culture and safety behaviors of metropolitan professional firefighters. A validated and reliable safety culture survey was used to assess the safety culture of a metropolitan fire department. A safety behavioral checklist was created and used to assess the safety behaviors of professional fire fighters. The sample for the study included 156 firefighters from a metropolitan fire department in North Carolina. A Pearson correlation was used to determine if there was a significant relationship between safety culture and safety behaviors. ANOVA and t-tests were used to determine if significant differences existed in safety culture and/or safety behavior on selected demographic factors. Data analysis revealed a significant correlation between safety culture and safety behavior. Results indicated the more positive safety culture is viewed, the more likely the firefighter is to practice safe behaviors. Findings also indicate that demographic factors such as education, marital status, work experience, and dependent status have no significance on how firefighters view safety culture and on the safety behaviors of firefighters. Data analysis did indicate a marginal significance in safety culture by participants who reported being moderately or severely injured ‘on the job’.

Quality in pharmacies includes aspects such as error management and safety issues. The objective of this thesis was to explore these aspects of quality in Swedish community phar-macies. The specific aims were to compare a paper-based and a web-based reporting system for dispensing errors, regarding reporting behaviour and data quality. The impact of an intervention; a technical barrier, for preventing dispensing errors was evaluated. A survey tool, the Safety Attitudes Questionnaire (SAQ), was adapted to Swedish pharmacies and used to describe the safety culture in these pharmacies. The potential relationship between safety culture and dispensing errors was also explored. Data was retrieved from the paper- and web-based reporting systems, semi-structured interviews as well as from a survey, using SAQ. The change in reporting system for dispensing errors increased the reporting of errors and enhanced the completeness of reported data. The web-based system facilitated follow-up and identification of preventive measures, but was associated with implementation problems. The intervention was associated with a significant decrease in the overall number of dispensing errors and, specifically, reports on errors with the wrong strength, and errors caused by registration failure in the pharmacy computers. The Swedish version of the survey tool, SAQ, demonstrated satisfying psychometric properties. No correlation between the SAQ Safety Climate dimension and dispensing errors was seen, while a positive relationship between the SAQ Stress Recognition dimension and dispensing errors was established. A number of other pharmacy characteristics, such as number of dispensed prescription items and employees, displayed positive relationships with dispensing errors. Staff age demonstrated a negative relationship with dispensing errors while other demographic variables such as national education background showed a positive relationship.

Problem: Nurses are potentially exposed to hazardous drugs (HDs) in their practice. HD exposure is associated with adverse outcomes (reproductive problems, learning disabilities in offspring of nurses exposed during pregnancy, and cancer occurrence). Safe handling precautions (safety equipment and personal protective equipment, [PPE]) minimize exposure to HDs and decrease the potential for adverse outcomes. Despite existing OSHA recommendations, adherence to precautions is below recommendations. The purpose of this study was to examine relationships among factors affecting nurses’ use of HD safe handling precautions, to identify factors that promote or interfere with HD precaution use, and to determine nurse managers’ perspectives on use of safe handling precautions. This study used a conceptual model which proposes that both individual and organizational factors influence precaution use. Methods: A cross-sectional, correlational design was used. Nurses (N = 165; 46% response rate) from oncology centers across the US who reported handling chemotherapy completed a mailed survey. Instruments measured HD precaution use, knowledge, self efficacy, barriers, perceived risk, conflict of interest, interpersonal influences and workplace safety climate. Hierarchical regression was used. Twenty managers of nurses handling chemotherapy were interviewed. Results: Nurses were experienced in oncology (M = 15.8 ± 7.6) yrs, well-educated (62.5% ≥BSN), certified in oncology nursing (85%), worked in outpatient settings (69%), and on average treated 6.8 ± 5.2 patients per day. Chemotherapy exposure knowledge was high (M = 10.9, ± 1, 0-12 scale); as was self efficacy for using PPE (M = 20.8 ± 3, 7-24 scale), and perceived risk (M = 3.14 ± .6, 0-4 scale). Total precaution use during HD administration and disposal was low (M = 1.9, SD = 1.1, 0= never to 5 = 100%). Nurse characteristics did not predict HD precaution use. In the final model (R2 = .29, F (2, 155) = 24.6, p < .000), fewer patients per day, fewer barriers and better workplace safety climate were independent predictors of higher precaution use. Conclusions: Results emphasize the importance of organizational influence on nurses’ HD safe handling precaution use and suggest fostering a positive workplace safety climate and reducing barriers as interventions.

Safety is considered as one of the most important areas in future research and development within the automotive industry. New functionality, such as driver support and active/passive safety systems are examples where development mainly focuses on safety. At the same time, the trend is towards more complex systems, increased software dependence and an increasing amount of sensors and actuators, resulting in a higher risk associated with software and hardware failures. In the area of functional safety, standards such as ISO 26262 assess safety mainly focusing on qualitative assessment techniques, whereas usage of quantitative techniques is a growing area in academic research. This thesis considers the field functional safety, with the emphasis on how hardware and software failure probabilities can be used to quantitatively assess safety of a system/function. More specifically, this thesis presents a method for quantitative safety assessment using Bayesian networks for probabilistic modeling. Since the safety standard ISO 26262 is becoming common in the automotive industry, the developed method is adjusted to use information gathered when implementing this standard. Continuing the discussion about safety, a method for modeling faults and failures using Markov models is presented. These models connect to the previous developed Bayesian network and complete the quantitative safety assessment. Furthermore, the potential for implementing the discussed models in the Modelica language is investigated, aiming to find out if models such as these could be useful in practice to simplify design work, in order to meet future safety goals.

Abstract The sustaining management of the enterprise is in addition to increasing productivities and promoting with product quality, should be also based on "Safety". Perfect and systematical management for safe hygiene cannot only improve the industrial safety performance, but also enhance the job-satisfaction. In fact, "person" is just root. Master of management Peter Drucker also point out:"The spirit of the company should be created out by leader". What influence does the different leadership style and effective safety management on the industrial safety performance exactly is the topic of this study. The purpose of this study aims to understand the leadership styles for high-ranking management of each enterprise, the differences under the different background variables, and explore the moderations of leadership style for high-ranking management of each enterprise between industrial safety system and industrial safety performance, job-satisfaction. The scope of the research regard the high-risk industries affirmed by the Industrial Development Bureaus such as steel manufacturing industry, petrochemical industry and chemical industry etc. in Kaohsiung area as the main inquisition object. The valid samples were 88 copies in the aggregate. (Including 30 business units) Through statistic analysis, the major results in the study were as follows: 1. There is a significant positive correlation between industrial safety system, benevolence leadership and the industrial safety performance. The authoritarianism leadership and cognition industrial safety performance have no significant correlation. 2. There is a significant positive correlation between benevolence leadership, industrial safety system and the job-satisfaction. The authoritarianism leadership and job-satisfaction have no significant correlation. 3. The interactive effects between the industrial safety system and benevolence leadership on the industrial safety performance are significant, that means the industrial safety system and the industrial safety performance don¡¦t reveal significant correlation under the interference of benevolence leadership. The benevolence leadership and the industrial safety performance reveal significant positive correlation. In other words, the higher degree benevolence leadership is, and the better industrial safety performance is. 4. The interactive effects between the industrial safety system and authoritarianism leadership on the job-satisfaction are significant, that means the industrial safety system and the job-satisfaction don¡¦t reveal significant correlation under the interference of authoritarianism leadership. The authoritarianism leadership and the job-satisfaction reveal significant negative correlation. In other words, the lower degree authoritarianism leadership is, and the higher job-satisfaction is. So, through the leadership style of the kindness and the management of the participate type, the high-ranking administrators cannot only improve the industrial safety performance effectively by adequate communication and encouragement, but also enhance the employee's job-satisfaction. On the contrary, through the authoritarianism leadership style, the rather strict management and the commending tone, based upon the conclusions of this study, the high-ranking administrators will not improve the industrial safety performance significantly, but reduce the employee's job-satisfactions. There was "authoritarianism " characteristic on most of the high-ranking administrators in the Taiwanese enterprises; they should establish the right leadership style on these grounds to promote organization performance successfully.
