SUN COAST PROJECT STUDY2Literature Review, Research Objectives, Research Question and HypothesesIntroductionSenior leadership at Sun Coast has identified several areas for concern that they believe could be solved using business research methods. The previous director was tasked with conducting research to help provide information to make decisions about these issues. Although data were collected, the project was never completed. Senior leadership is interested in seeing theproject through to fruition. The following is the completion of that project, and includes statement of the dilemmas, literature review, purpose statements, research methodology, design, and methods, research questions and hypotheses, data analysis, and findings. Statement of the Problems/DilemmasThere were six business dilemmas identified. Particulate Matter (PM)There is a concern that job-site particle pollution is adversely impacting employee health. Although respirators are required in certain environments, particulate matter (PM) varies in size depending on the project and job site. PM between 10 and 2.5 microns can float in the air for minutes to hours (e.g. asbestos, mold spores, pollen, cement dust, fly ash), while PM less than 2.5 microns can float in the air for hours to weeks (e.g. bacteria, viruses, oil smoke, smog, soot). Due to the smaller size of PM less than 2.5 microns, it is potentially more harmful than PM between 10 and 2.5 since the conditions are more suitable for inhalation. PM less than 2.5 are also able to be inhaled into the deeper regions of the lungs, potentially causing more deleterious health effects. It would be helpful to understand if there is a relationship between PM size and employee health. Air quality data have been collected from 103 job sites, which is reflected in PM size. Data is also available for average annual sick days per employee per job-site.
SUN COAST PROJECT STUDY3Safety Training EffectivenessHealth and Safety training is conducted for each new contract that is awarded to Sun Coast. Data for training expenditures and lost-time hours were collected from 223 contracts. It would be valuable to know if training has been successful in reducing lost-time hours and, if so, how to predict lost-time hours from training expenditures.Sound-Level Exposure Sun Coast’s contracts generally involve work in noisy environments due to a variety of heavy equipment being used for both remediation and the clients’ ongoing operations on the job sites. Standard ear-plugs are adequate to protect employee hearing if the decibel levels are less than 120 decibels (dB). For environments with noise-levels exceeding 120 dB, more advanced and expensive hearing protection is required, such as ear-muffs. Data have been collected for the primary variables that are believed to contribute to excessive noise. It would be important if
