The Dangers of halogens in the workplace

[ad_1]

halogens are highly reactive elements and can be harmful or even fatal in sufficient quantities. It is surprising to think that something as benign and table salt contains chlorine, which in its elements, is poisonous yellow gas. A small amount of bromine used in halogen bulbs and iodine is essential for the health of

5 halogens are :.

  • Fluoride
  • Chlorine
  • Bromine
  • iodine
  • astatine

halogens are nonmetals and found in the environment only in compounds or ions in many minerals and sea. Elements of their name is derived from two Greek words which when combined mean, ‘salt manufacture. When combined with hydrogen, halogens, to form compounds known as a halide, a series of very strong acids, one of which is hydrochloric acid.

Fluoride

At room temperature, it is pale yellowish- brown gas, one of the most reactive elements in existence. It is corrosive, toxic and highly toxic and even under cool, dark conditions, react with hydrogen explosion. Fluoride is such a reaction it is difficult to

found in the container where it can be stored safely. It is so powerful that if stored in normal laboratory glass, it is possible to act, forming kísilfkóroxíð, a very toxic gas which when inhaled causes lung edema could lead to death. It will be treated with materials such as Teflon, very dry glass or metals such as copper or steel, forming a protective layer of fluorine on the surface thereof. Fluoride is very corrosive, burning skin and eyes, and can cause respiratory problems if inhaled.

Chlorine

is highly toxic, pale greenish-yellow gas, which is about 2½ times as dense as air with choking, disagreeably pungent smell. Benign compound of chlorine and sodium has resulted in sodium chloride, common but necessary, our table salt. Chlorine is a powerful oxidant and packaging can explode if exposed to heat, igniting combustible. It is used to manufacture many chemicals, including chloroform and carbon tetrachloride. It has been implicated in the depletion of the ozone layer in the atmosphere. Chlorine gas was first used as a weapon in World War I. It has reappeared in the war in Iraq where chlorine bombs have been used by insurgents against coalition forces and locals ..

Bromine

Is brown volatile liquid that fumes are toxic and corrosive. It has a strong, disagreeable, suffocating odor, similar to chlorine. Its name is derived from the Greek word for’stench ‘which aptly describes it. It is a powerful oxidizing agent and can explode violently if it contacts Acetylene, ammonia, potassium, and quite a few other elements and compounds. It is very dangerous in contact with the skin, causing burns and blisters. If inhaled, toxic fumes can cause serious damage to the respiratory system.

iodine

This grayish black solid is at least chemically active halogen. It is highly corrosive and can cause dark pigmentation of the skin, penetrating burns, corneal irritation and eye damage that can lead to blindness. If inhaled, it is not as toxic as some of the other halogens which can cause shortness of breath and can lead to serious respiratory problems. Iodine is volatile solid that will explode if it comes into contact with bromine and certain other elements and compounds.

astatine

This is the rarest naturally occurring element and scientists estimate that there is not more than 25 grams, less than a penny, in the crust. It is radioactive and is rapidly, making it difficult to study its properties. It is essentially due to the decay of uranium and thorium.

After reviewing the properties of halogens, it becomes very obvious that they must be

treated carefully in the workplace. All these factors present varying degrees of risk, ranging from violent explosions titanium tetrachloride to risks dense clouds of hydrochloric acid gas.
