Exposition Des Travailleurs Aux Substances Chimiques Et Aux Agents Biologiques Dans Les Usines De Biométhanisation Des Matières Organiques Putrescibles : Évaluation Exploratoire, Bouchra Bakhiyi, Geneviève Marchand, Yves Cloutier, Yves Beaudet, Marc Veillette, Marie-Ève Dubuis, Hamza Mbareche, Joseph Zayed, Caroline Duchaine, Jacques Lavoie

Rapports de recherche scientifique

La biométhanisation est un procédé de transformation anaérobie des matières organiques putrescibles (MOP) en biogaz et en digestat destiné à l'épandage en milieu agricole. Ce procédé est en forte croissance en raison de la Politique québécoise de gestion des matières résiduelles qui prévoit le bannissement de l'enfouissement des MOP, et ce, dès 2020. L'exposition des travailleurs affectés aux activités de biométhanisation a fait l’objet de peu de publications scientifiques. L'objectif général de cette recherche est donc d'évaluer de manière exploratoire l’exposition de ces travailleurs. Plus spécifiquement, cette étude vise à 1) détecter et à mesurer la présence et les concentrations …

Rapports de recherche scientifique

L’exposition aux bioaérosols de différents milieux de travail n’est pas étrangère au développement de maladies respiratoires; les moisissures y tiendraient d’ailleurs un rôle important. De par les activités qui y sont menées, certains milieux de travail génèrent de grandes quantités d’aérosols (incluant des moisissures), qui proviennent de la matière présente dans l’environnement. Des facteurs, tels que l’humidité relative et le type de ventilation du bâtiment peuvent accentuer l’effet de l’exposition aux moisissures dans les environnements touchés. La présence de moisissures dans l’air a d’abord été confirmée par l’emploi de méthodes d’analyse par culture. Ces méthodes dites classiques induisent un …

Ability Of The Iso Predicted Heat Strain Method To Predict A Limiting Heat Stress Exposure, Edgar Prieto

USF Tampa Graduate Theses and Dissertations

Heat stress is one of many physical agents to which thousands of workers are under constant exposure. Oftentimes it is necessary to work above the WBGT-based heat stress exposure limits. It is therefore important to consider alternative measures that include an exposure time limit to manage the heat stress. Predicted Heat Strain (PHS) (ISO7933) is one of those alternatives. PHS uses both personal factors like height and weight and job factors of environment, metabolic rate and clothing. The purpose of this project is to determine whether the PHS is an adequate method to predict short term exposure limits.

The study was also conducted to determine UFP and nanoparticle exposure in the breathing zones of the welders as well as the breathing zones of pipefitters and fire watchers, who commonly sit 6ft behind the welding arc. In order to determine if UFP and NP exposures differed with base metal and filler wire, all welding processes utilized the same welding machine for metal …

Nonlinear Associations Between Working Hours And Overwork-Related Cerebrovascular And Cardiovascular Diseases (Ccvd), Ro-Ting Lin, Lung-Chang Chien, Ichiro Kawachi

School of Public Health Faculty Research

Long working hours are recognized as a risk factor for cerebrovascular and cardiovascular diseases (CCVD). We investigated the relationship between working hours and different CCVD severity outcomes—death, disability, and illness—across industries in Taiwan from 2006 to 2016. We applied a generalized additive mixed model to estimate the association between working hours and the rate of each severity outcome, adjusted for salary, unemployment rate, time, and a random intercept. Industry-average working hours were significantly associated with each outcome level of overwork-related CCVD, especially when monthly working hours increased from 169 (relative risk [RR] = 1.46, 95% confidence interval [CI] 1.002–2.12) to …

Developing Certification Exam Questions: More Deliberate Than You May Think, Cheryl (Cheri) L. Marcham, Treasa M. Turnbeaugh, Susan Gould, Joel T. Nader

Publications

For more than 40 years, the multiple-choice examination has been the standardized assessment tool used in the certification process of OSH professionals (Wright, Turnbeaugh, Weldon, et al., 2015). The use of a multiple-choice exam to award a credential, however, has been criticized by many OSH professionals. This may be primarily due to a perception that relates to their previous academic experience with multiple-choice exams and a misunderstanding of the science behind the development of such exams.

The use of standardized tests clearly ensures a consistent and rapid method of scoring, but the use of such tests is legally defensible only …

Assessing The Ordinality Of Response Bias With Item Response Models: A Case Study Using The Phq-9, Venessa N. Singhroy

Dissertations, Theses, and Capstone Projects

Improper scale usage in psychological and clinical assessment is an important problem. If respondents do not use the scales in a consistent manner, the reliability of a composite is likely to be attenuated. This is particularly problematic when particular items are singled out for special treatment or when subscales are of interest, not just a total score. This study used both non-parametric and parametric item response theory (IRT) methods to gain further insight into the validity of the PHQ-9, a dual purpose instrument that assesses the severity of depressive symptoms using nine Likert-scale items and allows the investigator to establish …

Nanoparticle Penetration Of Respirator Masks At Construction Sites, Jefferson W. Doehling

Honors College Theses

This experimental investigation studies the effectiveness of N95 respirators at blocking particles between 11.5 and 154 nm in diameter during 4 different construction activities. It is well known that large amounts of dust and debris are generated during construction activities. New research has found that significantly more nanoparticles are generated during construction activities than previously thought. Consequently, the N95 respirators commonly worn to protect against these particles are only rated to block 95% particles larger than 0.3 microns in size. In this investigation, two respirator models were tested, a NIOSH TC-84A-0007 pleated N95 respirator and a NIOSH 42CFR84 foldable N95 …
