Catastrophic emissions

Emissions of phosgene most commonly arise as a result of its release during manufacture and use, its formation from the decomposition of chlorinated hydrocarbons, and its formation from the photochemical oxidation of air-borne chlorinated organic materials, particularly the C, and C chloroalkanes, and chloroethenes. The location and estimation of air emissions from sources of phosgene have been described by the US Environmental Protection Agency [2088b], Catastrophic emissions and accidental spills and leaks are discussed in Section 3.6. 

It has been estimated (although without substantiation) [1484] that some ten thousand workers were potentially at risk to occupational phosgene exposure during its manufacture or use in 1976. In addition, exposure to phosgene can result from the decomposition of various chlorinated organic materials as described in Section 3.3. Risks to the populace, as a result of catastrophic emissions, are described in Section 3.6. 

Catastrophic Incident An incident involving a major uncontrolled emission, fire or explosion that causes significant damage, injuries and/or fatalities onsite and have an outcome effect zone that extends into the surrounding community. 

Catastrophic release Under OS HA PSM and EPA RMP, it means a major uncontrolled emission, fire, or explosion, involving one or more highly hazardous chemical substances (per OSHA) or regulated substances (per EPA) that presents serious danger to employees in the workplace (per OSHA) or imminent and substantial endangerment to public health and the environment (per EPA). 

Catastrophic Release - A major uncontrolled emission, of hazardous material that presents serious danger to workers or the public. 

Individuals and companies that buy insurance products could be stimulated to address climate change-seeking mechanism to facilitate mitigation of GHG emissions and adaptation to the inevitable impacts of climate change [16]. In addition, the insurance companies themselves are motivated to take significant actions to mitigate GHG emissions and increase adaptive capacity to reduce overall uncertainty and other barriers to insurability and are also motivated to limit the insurers potential exposure to catastrophic risks in excess of their capacity to avoid the potential for property and liability claims in excess. 

Atmospheric vapor releases or liquid spills within a petroleum or related facilities commonly occur every day. They are a major source of the origin of catastrophic incidents. In order to provide an inherently safer facility the common release of process vapors to atmosphere or liquids to grade within the facility should be prevented or eliminated wherever practical. Not only does this improve the safety of a facility it also decreases the amount of fugitive emissions or liquids that occur therefore decreasing any potential harm to the environment. Containment of waste gases and liquids, human surveillance, increased testing, inspection and maintenance, gas detection and adequate vapor dispersion features are all measures to lesson the probability of an incident occurring. 

In general, the use of FE signals accompanying the deformation and fracture of composites offer elucidation of failure mechanisms and details of the sequence of events leading upto catastrophic failure. The extent of interfacial failure and fiber pull-out are also potential parameters that can be determined. FE can assist in the interpretation of AE and also provide an independent probe of the micro-events occurring prior to failure. FE has been shown to be sensitive to the locus of fracture and efforts are underway to relate emission intensity to fracture mechanics parameters such as fracture toughness (Gjp). Considerable work still remains to fully utilize FE to study the early stages or fracture and failure modes in composites. 

At a current of the order of 1 to 2 jlA, a catastrophic decrease of the field-emission current is observed. In a small fraction of a second, the field emission current drops to zero. 

Global warming pressure groups would have the world believe that catastrophic changes in the earth s climate will occur without drastic limitations of carbon dioxide emissions—this in spite of the fact that the carbon dioxide levels in the earth s atmosphere have been much higher than today s for much of geological history. For example, as documented by the work of Berner,13 atmospheric carbon dioxide concentrations were some five 15... 

The products from these reactions are distributed into the galaxies by slow emission from the red giants and by the catastrophic explosions of novas and supernovas. This dispersed material condenses in the population II and later the population I stars...
