Why the gap? Experts say there are different approaches to mass control and political protests. „Riot`s control officers are much more often used to suppress communication rights than they are used to stop real unrest,“ Anna Feigenbaum, author of a groundbreaking book on tear gas, told Vice. Tear gas, experts say, is often a method of deterrence that is used as a first reaction rather than as a last resort. Exposure to tear gas can have many short- and long-term health effects, including the development of respiratory diseases, serious eye injuries and diseases (such as traumatic visual neuropathy, keratitis, glaucoma and cataracts), dermatitis, damage to the cardiovascular and gastrointestinal systems, and death, especially in cases where high concentrations of tear gas or the use of tear gas in enclosed spaces.  The use of tear gas during recent demonstrations has caused frustration and turned into a political debate that has stirred controversy over why police officers are allowed to use tear gas against civilians, but not during the war. Tear gas seems admirably adapted to isolate the individual from the mob spirit… he is thrown into a state where he can think of nothing but relieving his own distress. Under such conditions, an army disintegrates and a mob ceases to be; He becomes a blind stampede to move away from the source of torture. As with all non-lethal or less lethal weapons, the use of tear gas poses a certain risk of serious and permanent injury or death.   This includes the risk of being hit by tear gas canisters that can cause severe bruising, vision loss or skull fractures resulting in immediate death.  A case of severe vascular injuries due to tear gas grenades has also been reported in Iran, with high rates of nerve damage (44%) Amputation (17%), as well as cases of head injuries in adolescents. The first line of defense is the wearing of an artificial respirator.  Alternatively, the entire face should be covered with a wet cloth, wet bandana or mask; with a tight show z.B.
swimming goggles. You have to wear full clothes, the goal is to cover the skin as much as possible.  Do not wear contact lenses or make-up. Try to move towards a higher descent when the tear gas particles settle.  Law enforcement around the world relies on tear gas to disperse crowds, but its use is controversial. Supporters say it is a crucial tool for maintaining law and order, while some experts say there are better ways to respond to protests. As police across the country try to disperse protesters, allegations have emerged on social media that tear gas is a chemical weapon banned during the war, but legal for repressive purposes. There are other approaches. In Stockholm, for example, officials known as dialogue police negotiate with protesters and explain police actions.
In Berlin, police use placards and depositions to keep protesters informed of their intentions. Spanish police are using third-party negotiators [PDF] to exchange information between the police and the public. Supporters say that such community policing practices, which aim to facilitate peaceful political expression rather than suppress it, can prevent escalation, which often ends with the use of tear gas by police. Glatter said tear gas not only irritates cells, but also activates pain receptors, causing intense pain in the eyes, throat, lungs, skin and mucous membranes. Tear gas can also cause excessive muscle spasms in the eye and sensitivity to light that leads to eye closure. Some support for the American interpretation of the protocol came from the United Kingdom and Japan.
