OHDMod© is a Microsoft® Excel workbook for predicting the oxygen content trends in environments where inert gas releases may lead to asphyxiation risks. ODHMOD uses a Near Field-Far Field approach and estimates the oxygen concentration percent by volume and as mmHg partial pressure over time in the two zones. In addition to output graphs, the time required for reaching a target level is provided. Results can be compared to reference values for typical human body reactions due to Oxygen Deficiency Hazards and the need for mitigation measures. Examples provide guidance on input values for multiple industrial scenarios. ODHMOD has a user-friendly multilingual interface like several other AIHA tools. This workbook is a product of collaboration between American Industrial Hygiene Association (AIHA) and Università degli Studi di Brescia (Italy). The details and description of the mathematical model and workbook can be found in: Elena Stefana, Filippo Marciano, Daniel Drolet, Thomas W. Armstrong. 2021, "A traditional Near Field-Far Field approach-based model and a spreadsheet workbook to manage Oxygen Deficiency Hazard", Process Safety and Environmental Protection 149, 537-556, https://doi.org/10.1016/j.psep.2020.11.014

Abstract
OHDMod© is a Microsoft® Excel workbook for predicting the oxygen content trends in environments where inert gas releases may lead to asphyxiation risks. ODHMOD uses a Near Field-Far Field approach and estimates the oxygen concentration percent by volume and as mmHg partial pressure over time in the two zones. In addition to output graphs, the time required for reaching a target level is provided. Results can be compared to reference values for typical human body reactions due to Oxygen Deficiency Hazards and the need for mitigation measures. Examples provide guidance on input values for multiple industrial scenarios. ODHMOD has a user-friendly multilingual interface like several other AIHA tools. This workbook is a product of collaboration between American Industrial Hygiene Association (AIHA) and Università degli Studi di Brescia (Italy). The details and description of the mathematical model and workbook can be found in: Elena Stefana, Filippo Marciano, Daniel Drolet, Thomas W.
