Risk Assessment Matrices For Workplace Hazards: Design For Usability, Roger C. Jensen, Royce L. Bird, Blake W. Nichols

Safety Health & Industrial Hygiene

In occupational safety and health (OSH), the process of assessing risks of identified hazards considers both the (i) foreseeable events and exposures that can cause harm and (ii) the likelihood or probability of occurrence. To account for both, a table format known as a risk assessment matrix uses rows and columns for ordered categories of the foreseeable severity of harm and likelihood/ probability of that occurrence. The cells within the table indicate level of risk. Each category has a text description separate from the matrix as well as a word or phrase heading each row and column. Ideally, these header …

Crosswalking Wet Bulb Globe Temperature And Heat Index, Paul Irvin

USF Tampa Graduate Theses and Dissertations

Wet bulb globe temperature (WBGT) is a common metric to represent the environmental conditions in the assessment of heat stress. Because WBGT requires some technical expertise and sufficiently accurate equipment, there is interest in using heat index (HI) as a substitute index for the environment. Because the underlying science for understanding heat stress exposures does not exist for HI, it is necessary to crosswalk between HI and a data-driven exposure method. Expanding upon previous research, the focus of this study is the exploration of the interrelationships between WBGT and HI. The simulated weather data of Morris et. al. (2019) served …
