Use Of Silica Dust And Lunar Simulants For Assessing Lunar Regolith Exposure, Layzamarie Irizarry-Colon

USF Tampa Graduate Theses and Dissertations

The utilization of the lunar regolith holds immense potential for future space exploration, but the potential health risks associated with lunar regolith are a significant concern. This literature review seeks to critically assess the use of silica and lunar simulants standards and permissible exposure limits (PELs) to evaluate the adverse health effects of lunar regolith. The literature review covers an extensive analysis of existing research, health risks, toxicological properties, and physical and chemical composition associated with silica, lunar simulants, and lunar regolith by using three main sources: regulations, scholarly articles, and Kennedy Space Center (KSC) discussion. This comprehensive analysis forms …

Assessment Of Iso Heart Rate Method To Estimate Metabolic Rate, Karl Williams

USF Tampa Graduate Theses and Dissertations

Thermal equilibrium is primarily maintained by the body’s ability to dissipate internal heat generated during muscle contraction. A number of methods have been used to quantify this thermal burden such as charts and observation of workplace activities and behavior, however these have varying levels of validity. ISO 8996 defines a more accurate method of metabolic rate estimation that uses heart rate and maximal work capacity (MWC); however this requires the use of laboratory settings and equipment that are rarely available in the field. Equations such as the ACSM metabolic equation for the total energy expenditure of walking, hereafter referred to …

Evaluation Of Two Methods To Estimate Wet Bulb Globe Temperature From Heat Index, Stephi Pofanl

USF Tampa Graduate Theses and Dissertations

The Wet bulb globe temperature (WBGT) is a common method to evaluate environmental factors that contribute to occupational heat stress. The Heat Index (HI) is readily available as an alternative to exposure methods. They both assess the most important contributors that are air temperature and humidity. WBGT also includes radiant heat and air motion. To account for radiant heat and/or air motion, some investigators have suggested adjustments to HI. The purpose of this study is to explore two methods to estimate the usefulness of WBGT from HI.

WBGT data were collected in a variety of locations that included direct sun …

Relationships Between Leading And Trailing Indicators At Construction Sites In Yanbu Industrial City, Saudi Arabia, Anas H. Halloul

USF Tampa Graduate Theses and Dissertations

Statement of Purpose: This study sought to assess the relationship between leading and lagging indicators in construction safety Management in the Kingdom of Saudi Arabia. In particular, it sought to determine whether construction sites with higher leading indicators predicted fewer incidents/accidents.Rationale for Study: Construction safety management is a critical occupational health concern globally. Scholars have researched approaches to improve safety measures and performance in construction sites. However, there is little discourse assessing the relationship between the leading indicators and the occurrence of incidents and accidents in construction sites. General Methods: A quantitative analysis was used in this study. Data were …
