A model of safety climate for the manufacturing sector

Cheyne, Alistair January 2000 (has links)
This research examines the structure of safety climate in the manufacturing sector. It does so by examining and comparing attitudes to, and perceptions of, safety issues in two manufacturing organisations and one organisation involved in the supply of construction materials. The concept of safety climate, and the associated concept of safety culture, have been the subject of much research and theory building in recent years and this thesis builds on previous work. The research framework used here employed a mainly quantitative methodology in order to investigate the architecture of safety climate using structural modelling. Statistical modelling has been applied in other safety studies, often involving safety climate as one variable in a global description of safety systems. However it has rarely been used to model and describe the structure of safety climate as an indicator of safety culture, as in this research. The structure of safety climate described in this research is characterised by the interaction of organisational, group interaction, work environment and individual variables, which provide indicators of influences on individual levels of safety activity. Structural models of the data from all three participating organisations fitted the broad pattern of organisational variables influencing group and work environment variables, which, in turn influence individual variables. A more detailed comparison of organisational structures, however, highlighted slight differences between the two manufacturing organisations and more pronounced differences between these and the construction material supply organisation, suggesting that most elements in the structure of attitudes to safety described here are industry specific. These results are explained in terms of working environments. Differences in structure, consistent with job roles, were also apparent between occupational levels. The research, in line with previous work in the field, has highlighted the importance of management commitment to, and actions for, safety, as well as the role of individual responsibility in the promotion of safety activity. The work reported here has emphasised their importance in developing and maintaining an organisational culture for safety.

The Food Safety Knowledge Level of Certified Food Managers Who Attended Two Self-Selected Training Courses

Payton, Larry Sean 03 October 2013 (has links)
The foodservice industry is dependent on millions of employees daily to ensure proper and safe food handling of food products consumed by the general public. The State of Texas requires food establishments’ management or person in charge be trained in food protection. For this inquiry, the researcher studied the knowledge level gained by food mangers from two food companies and two certification courses. There were 90 food service operations that participated in the study. The data was collected through the use of a food safety knowledge test instrument. The scope of the study was to explore the level of food safety knowledge of two self-selected certified food managers in Texas. Sixty-five percent (65.6%) of the certified food managers were certified by course A and 34.4% were certified by course B. The researcher explored two educational theories that are often utilized in the agricultural education discipline. Adult education and training programs in agriculture should use appropriate and effective instructional methods. Creswell and Martin (1993) inferred a linkage between adult education and instructional design as it related to agriculture. This study explored the phenomenon regarding certified food manager training courses and knowledge level through certification. In agricultural education, lives are affected through education and training. Trede and Wade (1993) suggested that agricultural education helps people improve their lives through an educational process using scientific knowledge. The participants’ knowledge test scores were as follows: course A (n=59) 72.9% and course B (n=31) 69.0%. The resulting t-test was determined to the knowledge test score of course A and course B, and proved not to be statistically significant at an alpha level .05. Thus, the researcher concluded instructional design and adult learning theory did not have an impact on the knowledge level of participants as a result of the two self-selected courses for certified food manager training in this study. Food safety knowledge of participants who spoke English or Korean as their native languages were analyzed closely as they represented the largest population of the participants. Korean as a native language represented the largest group at 45.6% of the population. English as a native language represented the second largest group at 43.3% of the population. Certified Food Manager Training is offered in these languages throughout Texas. Differences were found within the participants’ native or first languages. The certified food managers who identified as English and Korean native or first language resulted a statistically significant comparison when analyzed via independent t-test. The researcher recommends further research on affects of native language on certified food manager training. This research study discusses potential improvements that may be implemented in future research for certified food management training. The scope of this study utilized two self selected courses that were available to the participating certified food managers. For example, the Food Safety Knowledge Test instrument which was developed specifically for the scope of this research. Although this instrument was only used once it served as a suitable tool for this research project and could serve as a guide for the development of future research instruments. The researcher suggests that future researchers consider utilizing a tested and established research instrument. A study with a broader scope including courses supported by other National and State level accreditation organization as well as increasing the number of participant; may yield additional findings.

Patient safety: factors that influence patient safety behaviours of health care workers in the Queensland public health system

Wakefield, John Gregory, Public Health & Community Medicine, Faculty of Medicine, UNSW January 2009 (has links)
ABSTRACT Objectives: To develop and validate in an Australian setting, an instrument to effectively measure patient safety culture; to survey health care workers (HCWs) in a large public healthcare system to establish baseline patient safety culture; and, using the Theory of Planned Behaviour (TPB), to use behavioural modelling to identify the factors that predict and influence Patient Safety Behavioural Intent (PSBI) Eg. Reporting clinical incidents and speaking up when a colleague makes an error. Design: Cross sectional survey analysed with multiple logistic regression (MLR). Setting: Metropolitan, regional and rural public hospitals in Queensland, Australia. Participants: 5294 clinical and managerial staff. Main outcome measures: 1) Behavioural models for high-level Patient Safety Behavioural Intent (PSBI) for senior and junior doctors, senior and junior nurses, and allied health professionals. 2) Odds ratios to compare levels of PSBI between professional groups. Results: 1) The factors that influence high-level PSBI for each professional group give rise to unique predictive models. Two factors stand out as influencing high-level PSBI for all HCWs (R2 0.21). These are: i) Preventive Action Beliefs (Adjusted Odds Ratio (AOR) 2.38) (HCWs??? belief that engaging in the target behaviour(s) will lead to improved patient safety) and ii) Professional Peer Behaviour (AOR 1.79) (HCWs??? perceptions of the safety behaviour(s) of one???s professional peers). 2) There was a six-fold difference in the level of target behaviour (PSBI) across the clinical groups with few (29.6%) junior doctors having a high-level of PSBI. When compared with the junior doctors, the senior doctors were nearly 1.5 times more likely (Odds Ratio (OR) 1.46, 95% Confidence Interval (CI) 1.01-2.13), allied health staff 2.7 times more likely (OR 2.71, 95%CI 1.91-3.73), junior nurses 3.9 times more likely (OR 3.86, 95%CI 2.83-5.26), and senior nurses 6.0 times more likely (OR 6.01, 95%CI 4.78-9.16) to have high-level PSBI. Conclusions: This is the first published study to develop behavioural models of factors that influence HCWs??? intention to engage in behaviours known to be associated with improved patient safety. The findings of this study will greatly assist in the future design and implementation of targeted and cost-effective patient safety improvement initiatives.

Comparative Qualitative Research Distinguishing Safety Features Among Aviation Safety Action Programs in the United States Airlines

January 2016 (has links)
abstract: Over the years, aviation safety has been influenced by continuous implementations of both proactive and reactive policies by both regulatory boards and also, aviation service providers. This achievement has been possible mainly because of the safety management tools like the Aviation Safety Action Program (ASAP) which derives its roots from the much earlier Aviation Safety Reporting System (ASRS). Federal Aviation Administration (FAA) provides guidelines and procedures for installation and development of an ASAP, for every airline in the United States. In this study, how different United States air carriers apply ASAP in their organizations is investigated. / Dissertation/Thesis / Masters Thesis Technology 2016

A Product Development of Safety Car Seats for Children

Despotovski, Natali, Vuletic, Sonja January 2018 (has links)
Car accidents happens daily, and it is very important to protect all involved in a carno matter the age. Persons that are old enough and can take care of themselves, usescar seat belts to be protected in traffic. A child, however, must be placed andfastened in a safety seat by a parent or another caregiver, to be fully protected. Children that are correctly secured in safety seats have a 2.7 times bigger chance tosurvive a car crash without serious injuries compared to unstrained children (Berget al., 2000; WHO,2004). Regardless tests and safety seats that are available ontoday’s market, there are still issues that needs to be eliminated. Daily users of thisproduct are a good starting point since these people want a safe seat for their childthat can be easy to install and affordable; and they can best tell what issues theyencounter. Based on several scientific articles in a combination with interviews andobservations, issues with the safety seats could be confirmed. The primary issue isthe seat belt that is attached to the safety seat. Children can develop a habit ofwriggling out of the belt in safety seats. There are belt collectors available on themarket which holds the shoulder belts in place. In this way, it is harder for thechildren to slide out of the belt and helps to keep the belt properly positioned(BeSafe, 2018). Instead of having this as an accessory, it has been considered in thebelt that have been developed. Another issue is that the belt is complicated tofastened since two straps has to be simultaneously clicked in the belt buckle. If thisis done incorrectly, the belt cannot be fastened, and it takes time to try it again. Tomake this easier, two straps and the strap between the child's leg will be fastenedseparately in a seat buckle each. In this way, parents and other caregivers will beable to fasten the belt easy and properly. They will also be sure that the child issafely fastened and will minimize injury during an accident or another situation.

A balanced score card perspective of the safety management of two exemplary construction companies in the Western Cape

Hannie, James January 2015 (has links)
Magister Commercii - MCom / Occupational Health and Safety is largely determined by the creation of a Safety Culture that minimises risk. In South Africa the construction sector is the second most hazardous industry after mining. This study focuses on two exemplary construction firms in the Western Cape. The main research question is "How do the companies ensure coherent safety management practices that create a safety culture?" Based on a modification of a Balanced Health and Safety Scorecard for the Construction sector five sub-questions address safety management practices from a Management Perspective, an Operational Perspective, a Learning Perspective and a Client and Compliance Perspective. Data has been gathered from company documents, semistructured interviews, together with on-site observation. In conclusion the study reveals that management commitment, active communication and employee acknowledgement contribute positively to creating an effective safety culture on-site. Further studies are recommended with a specific view on small and medium companies in the construction sector.

Identification and analysis of manual materials handling tasks within a commercial warehouse in South Africa

Walraven, Lynne Louise January 1989 (has links)
Lifting and overstraining are major causative factors related to musculoskeletal injuries and low back pain. A great number of work-related injuries arise from the handling and/or mishandling of materials. Hence there is a need to quantify risk factors in situ and develop guidelines for safe lifting practises in industry. The aim of this study was to make appropriate in situ quantification, within a commercial warehouse, of the stresses and physical demands imposed on the worker when performing two handed lifts in the sagittal plane. The performance of employees was assessed under normal working conditions through an observational methodology of data collection. Task performance evaluation was based on detailed measurement of all containers handled, an activity and time analysis, and the 'Work Practices Guide to Manual Lifting’ (NIOSH, 1981) which was used as the primary guide to developing theoretical recommendations to probable MMH risk factors for the workers involved. Of the 191 tasks analysed 103 were deemed unsuitable. Appropriate task factor adjustments were made where necessary to both the frequency and Hfactors (horizontal distance between the centre of gravity of the container and that of the worker) in order to reduce the risk factor for the workers

Safety first : En kvantitativ studie om ledares säkerhetsklimat och safety performance i byggbranschen

Eriksson, Emil, Forssén, Michael January 2022 (has links)
Denna kandidatuppsats syftade till att mäta säkerhetsklimatet bland ledarna i en organisation verkandes inom elbranschen och jämföra detta med branschgenomsnittet samt andra branscher. Vidare undersöktes säkerhetsklimatet i relation till safety performance inom organisationen. Studien syftade även till att finna samband och skillnader relaterade till upplevelsen av klimatet som baseras på faktorer såsom individens erfarenheter och sociala omgivning. Dessa faktorer låg till grund för kategorierna ålder, år i organisationen och yrkesbefattning. Frågeställningar uppsatsen ämnade att besvara var: Skiljer sig denna organisations resultat jämfört med andra branscher? Hur ser sambanden ut mellan ledarnas säkerhetsklimat och safety performance? Finns det samband mellan social omgivningen såsom yrkesbefattning, ålder och antal år i organisationen som påverkar säkerhetsklimatet? För att mäta säkerhetsklimatet användes frågeformuläret nordic safety climate questionnaire (NOSACQ-50). Resultatet visade att organisationens säkerhetsklimat var högt jämfört med andra branscher men likväl fanns ändå rum till förbättring. Vidare visade resultatet att det var möjligt att observera samband mellan det goda säkerhetsklimatet och ökningen av riskobservationer/tillbud. Resultatet påvisade samband mellan lågt antal olyckor och högt upplevt säkerhetsklimat. Den sociala omgivningen kopplat till yrkesbefattningar tenderar att påverka uppfattningen av säkerhetsklimatet. Detta då chef/projektledare och ledande montörer svarar höga värden beroende på om frågorna rör ledning eller medarbetare. Analyserna visade på samband mellan upplevt säkerhetsklimat och erfarenheter, äldre individer skattade säkerhetsklimatet högre samt att de med fem år eller mindre hos organisationen skattade högre. Detta resultat skulle kunna ha influerats av organisationens ökade fokus i nutid gällande säkerhetsarbetet. Slutligen var det 60 respondenter med ledande positioner som deltog i denna studie.
