3D zone control: The strategy of 3D zone control intended to improve the safety of firefighters operating inside a burning structure.It attempts to safeguard the immediate locality of any space occupied by firefighters in resorting to various defensive actions that (a) confine the fire; (b) remove combustion products safely and effectively; or (c) mitigate dangers in the hot-gas layers.
The Essentials of Fire Fighting is the required training manual used in countless local fire departments and state/provincial training agencies in every region of the United States and Canada. Since the release of the first edition of this manual in 1978, more than 2.5 million copies of the Essentials of Fire Fighting have been distributed to ...
waste stream - Waste materials that are either of a particular type (e.g. 'timber waste stream') or produced a particular source (e.g. 'C&I waste stream'). waste treatment - where some additional processing is undertaken of a particular waste. This may be done to reduce its toxicity, or increase its degradability or compostability.
anti-dip stream A stream flowing in a direction approximately opposite to that of the dip of the underlying surface rocks. It is frequently, though not necessarily, an obsequent stream. [4] anticline A geological upfold that has an arch-like convex shape and its oldest beds near its center, often visible at the Earth's surface in exposed rock ...
Humans have had several effects on the flood pulse. Through ecosystem alterations such as dams, debris removal, channelization, levees, navigation, irrigation, contamination, logging, fire suppression, species introduction, and agricultural runoff, humans have contributed to the destruction of wetlands and the extinction of species.
The timeline for the Palisades Fire investigation is difficult to predict, Jones said, but noted the agency’s final report on the 2023 Maui wildfire did not come out until more than a year after ...
Riffles are very important to the life in a stream, and many aquatic species rely on them in one way or another. Many species of benthic macroinvertebrates rely on the highly oxygenated, fairly unsedimented waters present in a riffle. Many species of fish, including rare and endangered species use riffles to spawn in.
Much agricultural pollution is exacerbated by surface runoff, leading to a number of down stream impacts, including nutrient pollution that causes eutrophication. In addition to causing water erosion and pollution, surface runoff in urban areas is a primary cause of urban flooding , which can result in property damage, damp and mold in ...
