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 earmuffs. Historical data have been collected from 1,503 contracts for several variables that are believed to contribute to excessive dB levels. It would be important if these data could be used to predict the dB levels of work environments before placing employees on-site for future contracts. This would help the safety department plan for procurement of appropriate ear protection for employees. New Employee TrainingAll new Sun Coast employees participate in general health and safety training. The training program was revamped and implemented six months ago. Upon completion of the training programs, the employees are tested on their knowledge. Test data are available for two groups: Group A employees who participated in the prior training program and Group B
SUN COAST RESEARCH6employees who participated in the revised training program. It is necessary to know if the revisedtraining program is more effective than the prior training program. Lead ExposureEmployees working on job sites to remediate lead must be monitored. Lead levels in blood are measured as micrograms of lead per deciliter of blood (μg/dL). A baseline blood test is taken pre-exposure and postexposure at the conclusion of the remediation. Data are available for 49 employees who recently concluded a 2-year lead remediation project. It is necessary to determine if blood lead levels have increased. Return on InvestmentSun Coast offers four lines of service to their customers, including air monitoring, soil remediation, water reclamation, and health and safety training. Sun Coast would like to know if each line of service offers the same return on investment. Return on investment data are availablefor air monitoring, soil remediation, water reclamation, and health and safety training projects. If return on investment is not the same for all lines of service, it would be helpful to know where differences exist. Literature ReviewAfter providing a brief introduction to this section, students should include the literature review information here. Delete this before you begin.Research ObjectivesSun Coast has specific concerns for the health and safety of their workers, also they are interested in understanding if the programs they have in place are adequate in their depth and scope. To address these concerns, it is important to narrow the research objectives to specific
SUN COAST RESEARCH7areas. These research objectives will be used to provide Sun Coast solutions to their concerns and help drive the restructuring of their health and safety programs.
