Soil gases (soil atmosphere [1]) are the gases found in the air space between soil components. The spaces between the solid soil particles, if they do not contain water, are filled with air. The primary soil gases are nitrogen, carbon dioxide and oxygen. [2] Oxygen is critical because it allows for respiration of both plant roots and soil ...
Only pure chemicals belong here not fuel air mixtures to be here a gas must have an upper explosive limit of 100%. Pages in category "Explosive gases" The following 9 pages are in this category, out of 9 total.
Of greatest concern to the environment are secondary explosives, such as TNT, RDX, and HMX because they are produced and used in the greatest quantities. [2] Explosives and their residual post explosion products can partition between multiple environmental compartments including aquatic, soil, atmosphere, and the biosphere. [2] [3]
An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: chemical energy, such as nitroglycerin or grain dust
Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
A balloon filled with gaseous hydrogen exploding.. A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.
Environmental regulators have found explosive levels of methane in a popular Berkeley park. Regulators and the city are sparring over the source of the gas and what to do about it.
