Comparison Of The Effectiveness Of Disinfectant-Impregnated Wipes Versus Detergent Wipes For Surface Decontamination, Jacob Amadin

USF Tampa Graduate Theses and Dissertations

Over time, there is an increased need to adopt more advanced and effective ways of disinfection. The emergence of the coronavirus-2019 (COVID-19) pandemic reminded the world on the importance of disinfection. Disinfection has been a routine in the healthcare setting. However, with the current pandemic problem, it is more prominently and persistently done in the domestic setting and other business settings beyond healthcare. As such, the use of most disinfectants and detergent wipes to achieve a near sanitized environment has become a common practice around the globe. This research presents the efficacy of disinfectant impregnated versus detergents wipes through comparison. …

Does Time-Weighted Averaging For Wbgt And Metabolic Rate Work For Work-Recovery Cycles?, John W. Flach

USF Tampa Graduate Theses and Dissertations

Heat stress affects thousands of works annually by causing heat-related illnesses. Wet bulb globe temperature (WBGT) is a widely accepted metric to assess the environmental contributions to heat stress. WBGT-based occupational exposure limits (OELs) include the ACGIH TLVs and the NIOSH RELs. The OEL threshold is adjusted downward with increasing metabolic rate. Further, there is an OEL for acclimatized and non-acclimatized workers. An often-recommended intervention found within a heat stress management program is work-recovery cycles to manage exposure. To prescribe work-recovery cycles, the common practice is to use time-weighted averaging (TWA) for the WBGT and the metabolic rate. The purpose …

Acclimatization Protocols And Their Outcomes, Ayub M. Odera

USF Tampa Graduate Theses and Dissertations

Heat acclimatization provides the opportunity to better tolerate heat stress. Different methods are used to acclimatize participants as part of heat stress studies in the laboratory. The usual acclimatization protocols are greater than the occupational exposure limit represented by the ACGIH TLV® and NIOSH REL. The purpose of this paper was to examine the acclimatization state prior to and at the end of a one-week acclimatization program using two acclimatization protocols.

Prior heat stress studies at the University of South Florida (USF) used two heat stress conditions for participants’ acclimatization. Participants (n = 43) were evaluated using four different studies …

Face Mask Use To Protect Against Covid-19; Importance Of Substrate, Fit, And User Tendencies, Evelyn Kassel

USF Tampa Graduate Theses and Dissertations

In 2019, a novel respiratory illness appeared in China and spread rapidly though the country. It was determined that the SARS–CoV-2 virus was the cause of the COVID-19 pandemic. By the end of 2020, almost every continent was experiencing the effects of COVID-19. The virus caused health officials difficulty in determining its route of transmission. They worked tirelessly to discover it was spread via respiratory droplets. Panicked buyers wiped out protective equipment like medical masks and respirators, regardless of what was needed. Essential employees and first responders were subject to large scale personal protective equipment (PPE) shortages as health organizations …
