An incinerating toilet is a type of dry toilet that burns human feces instead of flushing them away with water, as does a flush toilet. [1] The thermal energy used to incinerate the waste can be derived from electricity, fuel, oil, or liquified petroleum gas. They are relatively inefficient because of the fuel used. [2]
A simpler, unenclosed, chemical toilet may be used in camping, travel trailers (caravans) and on small boats. [3] Many chemical toilets use a blue dye in the bowl water. In the past, disinfection was generally carried out by mixing formaldehyde, bleach, or similar chemicals with the toilet water when flushed. Modern formulations are nitrate ...
A chemical burn occurs when living tissue is exposed to a corrosive substance (such as a strong acid, base or oxidizer) or a cytotoxic agent (such as mustard gas, ...
Chemical burns can be caused by over 25,000 substances, [2] most of which are either a strong base (55%) or a strong acid (26%). [36] Most chemical burn deaths are secondary to ingestion . [ 2 ] Common agents include: sulfuric acid as found in toilet cleaners, sodium hypochlorite as found in bleach, and halogenated hydrocarbons as found in ...
The resulting chemical reaction can cause an explosion or a breakdown of the chemicals releasing toxic gases. Water should be used in that case. [8] [9] ABC dry chemical is inappropriate for certain metal fires and does not possess a saponification characteristic and should therefore not be used on Class K / Class F fires. [10]

To partially offset the cost of the FGD installation, some designs, particularly dry sorbent injection systems, further oxidize the CaSO 3 (calcium sulfite) to produce marketable CaSO 4 ·2H 2 O that can be of high enough quality to use in wallboard and other products. The process by which this synthetic gypsum is created is also known as ...
Flare stack at the Shell Haven refinery in England. A gas flare, alternatively known as a flare stack, flare boom, ground flare, or flare pit, is a gas combustion device used in places such as petroleum refineries, chemical plants and natural gas processing plants, oil or gas extraction sites having oil wells, gas wells, offshore oil and gas rigs and landfills.
