Differential pressure hazards (Pressure difference other than hydrostatic, causing strong water flow, usually towards the hazard) [46] Diver may get drawn into moving machinery or trapped against an intake opening, and may be directly injured or unable to escape and may run out of breathing gas and drown.
Divers must avoid injuries caused by changes in pressure. The weight of the water column above the diver causes an increase in pressure in proportion to depth, in the same way that the weight of the column of atmospheric air above the surface causes a pressure of 101.3 kPa (14.7 pounds-force per square inch) at sea level.
Evaporation under reduced pressure allows it to be concentrated further to about 40%, but then it decomposes to perchloric acid, chlorine, oxygen, water, and chlorine dioxide. Its most important salt is sodium chlorate, mostly used to make chlorine dioxide to bleach paper pulp. The decomposition of chlorate to chloride and oxygen is a common ...
Snorkel breathing is inherently negative pressure breathing, as the lungs of the swimmer are at least partly below the surface of the water. [16] There appears to be a connection between negative pressure breathing and a higher risk of pulmonary oedema while diving, as it increases the pressure difference between alveolar blood and gas.

The proponents of raw water praise the fact that it doesn't contain chemicals like chlorine, fluoride or chloramines -- but that might not be a good thing. Why that ‘raw water' trend is actually ...
Hypochlorous acid is an inorganic compound with the chemical formula Cl O H, also written as HClO, HOCl, or ClHO. [2] [3] Its structure is H−O−Cl.It is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming a hypochlorite anion, ClO −.
A chloride ion is a structural component of some proteins; for example, it is present in the amylase enzyme. For these roles, chloride is one of the essential dietary mineral (listed by its element name chlorine). Serum chloride levels are mainly regulated by the kidneys through a variety of transporters that are present along the nephron. [19]
Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill bacteria, viruses and other microbes in water. This method is used to kill bacteria, viruses and other microbes in water.
