Tear gas killing lungs and blindness and lead to death

Tear gas killing lungs and blindness and lead to death

Returns the historical sources the use of tear gas to about a thousand years ago, according to earlier Chinese in this area with the loss of their enemies vision, being tossed to the ground pepper envelope with rice straw. The tear gas from the old methods used to control the civilian protests and rallies, and end the riots.

Deadly gases damage the so-called tear

What is happening now is the use of police and security forces of tear gas bombs, to disperse political demonstrations, we differentiate between States described as democracy and qualify the dictatorship.

Tear components if they are not internationally prohibited!

And tear gas consists of solid particles micro turn when released in the atmosphere, causing injuries to her breathing with different symptoms, ranging from coughing and burning lungs and eyes, tears and sometimes lead to burns or temporary blindness, and in rare cases leads to continuous vomiting leading to death.

The tear gas on any mucous membranes in the eye, nose, mouth and lungs, causing crying and sneezing and coughing and difficulty in breathing, this is done by using black pepper spray and three chemicals symbolised by the letters (CNN), (CR) and (CS).

And vary the effects of tear gas by type and quantity, which breathed the targeted person, result in the world these gases almost 15 kinds of best three differ according to their effects:

-Least influential: it is commonly made of gas (CNN) the timely effect which fades quickly.

-Average effect: manufacture of gas (NCS) more effective and is toxic and harmful to the environment.

-The strongest impact: was used in 1956 because of ongoing vomiting causing effects may lead to death.

Tear bomb components:

And make the tear gas used to disperse political protests, mostly from an external body of aluminium above five holes and the bottom hole, all covered with a layer of wax adhesive, and launching tear bomb to melt wax adhesive layer and outflow of gas from the bomb.

Damage resulting from exposure to tear gas.

And could cause exposure to tear gas for long periods in poorly ventilated places, serious health problems, including glaucoma causes sometimes, and second degree burns, and death resulting from chemical burns to lungs or pharynx, exposing pregnant women to abortion.

Human rights organizations and advises international political wishing to demonstrate, to prevent the effects of tear gas, using masks, or a handkerchief moistened with water and vinegar on the nose, or already face wash with water and olive oil SOAP, and not touching the eye when injury.

Laws regulations require democratic police force described to practice well to use tear gas, and not launched only if necessary taking into account the specific legal standards, but those standards are not paying attention to in many States that its security is used tear gas to disperse rallies.

Gas (CNN):

 

Alvinasayl chloride, a substance of interest in organic chemistry as a syntactically correct for other molecules derived. Consists of alvinasayl chloride molecule asitavinon rate, historically has been used in riot under the name CN gas.

Alvinasayl chloride is available commercially and can be manufactured using the interaction of Friedel-c. crafts by unsheathed him gasoline with alklorwasitil chloride in the presence of aluminium chloride as a catalyst. alvinasayl chloride experience took place (the gas) during the first and second world wars, but not actually used for that purpose because of the high toxicity, and tear gas currently used widely is the CS gas.

And is very similar in its impact with the fence that Mr. s that causes irritation of the mucous membranes of the mouth, nose, conjunctiva, trachea and bronchi. And sometimes cause general effects such as fainting and loss of balance and confusion. As noted in rare instances skin irritation and contact dermatitis.

In high concentrations occur "Elsie" corneal tissue damage, and at least five deaths due to pulmonary damage caused by use of or alasvxia or both.

Gas (NCS):

Is the common name of klorobnzalmalononitrale, and is the tear gas used to disperse demonstrations. And is really not gas, but there is a spray of solvent volatile plus a alklorobnzalmalononitrale (NCS), and is solid at room temperature. Gas is considered "NCS" non-lethal material, American has discovered two Ben Corson and Roger they will come in midlberi College in 1928, and derived his name is common (NCS) from the first two letters of my name my family his discovered.

And developed a "CS" and underwent testing in field experiences of porton down in Wiltshire, England (and a field test used by the British army in chemical weapons experience) in the 1950s and 1960s, initially used on animals and then on volunteers from the British Army soldiers, it was noted that the impact of the "NCS" on animals is limited due to its less developed and the lacrimal a fur is some sort of protection. as result, Mr. Vegas and interaction 2-klorobenzaldihade wemalononitril by using "knovinagl" intensified interaction. And use a weak base (such as albibridine or alpyridine) as a catalyst, and method for producing article has not changed since westaoton discovered by Corson, some suggested a different base materials and methods without the use of solvents and means of stimulation with high waves minors to improve production.

The chemical, which has described the article 1928 discovered physiological properties: "cause certain types of bilateral alnitrile in the effects similar to the effects of gases of sneezing and tear gas, it does not cause damage when you catch her if being moist, but the catastrophic effects of dry powder (expression)".

Given that 2-klorobnzalmalononitrale are solid and not soft at room temperature, there are several techniques used to make using these solid as a spray: (dissolve and sprinkled a softened-resolving in an organic solvent, using powder "CS 2 ″ dry (Mr. s to powder form mslken wemzeror) – a Mr. svn thermal bombs hot gases).

15 type of tear gas, the most serious gas "CNN" and "CR"

From the effects of tear gas and other substances used in riot between simple and aladmaa between immediate and physical collapse vomit. The best known and most commonly used chemicals that "CNN" and "CR", although there were about 15 different types of tear gas (such as aladamsight or albromwasiton, and to me, and the sea). But using Mr. s was greater in view of the raised-with lower toxicity compared to other similar chemicals. Mr. effect depends on being in the form of lotion or spray, which is the size of the drops or particles spray solution of its impact on the human body.

Interact with moisture on the skin and in the eyes, causing the feeling of burning sensation and close the eyes immediately. Usually effects include runny tears from the eyes and nose, coughing, feeling a burning sensation in the nose and throat, loss of concentration, dizziness, and difficulty breathing. As Mr. r burns on the skin in moisturizing the race or if exposed to the Sun. And may cause severe coughing and vomiting when used in high doses. And ending all the symptoms almost within minutes of exposure.

Doubts about the classification of Mr. r that non-lethal gas

 

Although Mr. r classifies as non-lethal weapon used to disperse the crowd, but many studies have raised doubts about this classification. In addition to that may cause severe injury to the lungs, it might also affect great effects on the heart and liver.

On 28 September 2000, Professor Uwe Heinrich John Danforth study of us Consultancy Office using the FBI to CS gas at Mount Carmel Center (headquarters of the Protestant sect known as the aldaoodih). The study found that two factors determine the possibility of death as a result of the use of this gas: use gas masks or not, and whether they are attacked with gas in an open area or enclosed area. It was concluded that when not using a gas mask, and in the case of the attackers in an enclosed area ". There is a distinct possibility that contributes to such exposure to CS gas in causing death, and could even cause them directly ". Many studies also link between exposure to CS gas and an abortion, and is consistent with earlier reports from causing imbalance in the chromosomes (chromosomes) cells in mammals.

Also Mr. Vegas inside the body to be cyanide. The report issued by the u.s. Army Center for health promotion and preventive medicine to Mr. Vegas gas called "highly toxic fumes when heated to decomposition, and that Mr. gas at high concentrations pose a sooner to life and health. The report also said that providing immediate medical treatment to victims of this gas.

The MiBK solvent used to dissolve the "CR" to convert them to spray is harmful substance, causing skin infections and burns and damage to the liver cells. You can remove the effects of CS gas by using alkaline solution consists of water and sodium sulfite-concentration 5%.

(CR):

Or die bnzoxazibin (dual albnzoxazibin), is a tear, causing temporary paralysis, developed by the British Ministry of defence for use in breaking up demonstrations in the late 1950s and early 1960s this century.

And "CR" is a solid Crystal aroma similar to the smell of pepper. It is poorly soluble in water and is dissolved. There is usually a very small granules in the form of hanging in its material propylene glycol liquid. Unlike the apparent name, Mr. r gas is really a gas, but is solid at room temperature.

CR gas is chemically with alloxabin (a typical antipsychotic) and packaged in small cylinders (alibat), producing a cloud of spray at a steady rate when the temperature rises and the gas "CRV" is a tear, measuring 6 to 10 times the power of CS gas. CR gas causes irritation of the skin, particularly around moist areas of the body, and spasm in the eyelid causing temporary blindness, coughing and difficulty in breathing and panicking. It also can result in paralysis.

It is suspected that a CRV a carcinogen, is Sam if swallowed and both exposure and to a lesser extent of CS gas, and may cause death if exposed to large amounts of it, which could happen especially in poorly ventilated areas, where a person could inhale lethal dose within minutes. Cause of death in such cases is alasvxia or pulmonary crisis.

Continue to effect a "CR" for long periods, and may remain on the surfaces, especially porous surfaces, for up to 60 days.

In contrast to CS gas, which effects can be removed using large quantities of water, the use of water in the case of Mr. r might exacerbate its effects. And may cause Wash contaminated skin with CR in acute pain lasts for 48 hours after exposure.

And remedial actions in these cases are just measures to ease symptoms. Remove contaminated clothing, and wash the eyes, skin, and eye drops can be used to relieve the pain of the eyes.
