Associations of Cognitive Function Scores with Carbon Dioxide, Ventilation, and Volatile Organic Compound Exposures in Office Workers
A Controlled Exposure Study of Green and Conventional Office Environments Background: The indoor built environment plays a critical role in our overall well-being, both due to the amount of time we spend indoors (~90%) and the ability of buildings to positively or negatively influence our health. The advent of sustainable design or green building strategies reinvigorated questions regarding the specific factors in buildings that lead to optimized conditions for health and productivity. Objective: To simulate indoor environmental quality (IEQ) conditions in “Green” and “Conventional”...
A fatal case of CO(2) intoxication in a fermentation tank
Carbon dioxide (CO(2) ) is an odorless constituent of air. Higher concentrations can be detected in geothermal and automotive emissions, fermentation, and sublimation of dry ice. An unskilled worker entered a fermentation tank to clean it, which had not been done for about 5 months allowing for high concentrations of CO(2) to build up. A second worker entered the tank to rescue the first one. Shortly after both were found the first worker was rescued directly whereas the tank had to be rotated to pull the second worker out. Cardiopulmonary resuscitation was successful only for the first worker...
Assessment of the major hazard potential of carbon dioxide (CO²)
HSE has published a technical paper on its website which sets out an initial assessment of the hazards resulting from loss of containment incidents from vessels containing large quantities of carbon dioxide, and discusses the subsequent major accident potential associated with such events. Source:
La prévention des intoxications dans les silos à fourrage
Les silos utilisés en milieu agricole sont réputés être des espaces clos selon le Règlement sur la santé et la sécurité du travail (RSST). Les espaces clos tels que les silos à tour conventionnelle comportent de multiples risques. Ceux-ci sont liés en partie à une atmosphère trop pauvre en oxygène remplacé par le dioxyde de carbone, à une présence de substances toxiques dont le monoxyde d’azote et le dioxyde d’azote, à des microorganismes ou encore, à une présence...
Comparison of risks from carbon dioxide and natural gas pipelines
Carbon capture and storage (CCS) is likely to form a significant part of the UK's strategy for achieving its Kyoto targets for CO2 emission reduction. CO2 is not currently regulated as a dangerous fluid under the Pipeline Safety Regulations (PSR) so further investigation is required to determine if it should be re-classified. Source :
