Emission of Toxic Explosive and Fire Hazardous Gases in Coal Piles Stored Under Atmospheric Conditions
Granular activated carbons (GACS) were developed from hard and soft lignocellulosic byproducts. Three activation strategies were evaluated which employed phosphoric acid, carbon dioxide or steam. A portion of these carbons were also subjected to air oxidation after activation. Uptake of both non-polar and polar, small organic compounds were followed as was the adsorption of copper. Our results ...
متن کاملModelling Toxic and Physical Hazard in Fire
Studies of incapacitation and lethality in laboratory animals and human fire victims, resulting from exposure to thermal decompqsition products from many materials, indicate two main mechanisms of toxicity, narcosis (asphyxia) and irritancy. Narcotic effects are caused by the common asphyiant gases, CO, HCN, low 02' and CO2 and can be predicted to a reasonable degree with existing knowledge. Ir...
متن کاملThree toxic gases meet in the mitochondria
The rationale of the study was two-fold: (i) develop a functional synthetic model of the Cytochrome c oxidase (CcO) active site, (ii) use it as a convenient tool to understand or predict the outcome of the reaction of CcO with ligands (physiologically relevant gases and other ligands). At physiological pH and potential, the model catalyzes the 4-electron reduction of oxygen. This model was immo...
متن کاملFire fighter deaths from tanker truck rollovers.
Mobile water supply vehicles, known as tankers or tenders, are widely used to transport water to areas beyond a water supply system or where the water supply is inadequate. Incidents in volving motor vehicles account for approximately 20% of U.S. fire fighter deaths each year; cases involving tankers are the most prevalent of these motor vehicle incidents. During 1977–1999, 73 deaths occurred ...
متن کاملUV spectrophotometry for monitoring toxic gases
The need for gas compound measurement concerns overall three domains: environmental monitoring, emission measurement and risk assessment. These fields are different because of concentration range (from 10–3 to thousands mg.m–3). A fast technique has been developed based on UV spectrophotometry. Simple robust optics and absence of interference from water vapour and carbon dioxide are two of the ...
