Some chemical compounds that must be considered as dangerous are:1. AgNO3 (Silver Nitrate)
These compounds are toxic and corrosive. Colored bottles and store them in a darkened room and away from materials that burn easily.
Potential Hazards: May cause skin burns and blisters. Gas / vapor also causes the same thing.
2. HCl (Hydro Chloric Acid) - Acid Chloride
Hydrochloric acid is the aquatic solution of hydrogen chloride gas (HCl). He is a strong acid, and is a major component of gastric acid. These compounds are also widely used in industry. Hydrochloric acid must be handled with appropriate safety wewanti because it is a highly corrosive liquid.
Since the Industrial Revolution, it becomes extremely important compound and is used for various purposes, including the mass production of organic chemical compounds such as vinyl chloride for PVC plastic and MDI / TDI for polyurethane. Other small usability include use in household cleaning, production of gelatin, and food additives. About 20 million tonnes of HCl gas are produced annually.
Potential Hazards: concentrated hydrochloric acid (fuming hydrochloric acid) will form acid mist. Both the mist and the solution is corrosive to body tissues, with potential damage to the respiratory organs, eyes, skin, and intestines. Instantly hydrochloric acid mixed with other oxidizing chemicals, such as sodium hypochlorite (bleach NaClO) or potassium permanganate (KMnO4), toxic chlorine gas will be formed.
3. H2S (Hydrogen Sulfide)
Hydrogen sulfide, H2S, is a gas that is colorless, toxic, flammable and smells like rotten eggs. This gas can arise from biological activity when bacteria break down organic matter in a state without oxygen (anaerobic activity), such as in swamps, and sewage. Gas was also featured on the gas arising from volcanic activity and natural gas.
Potential Hazards: Inhalation of this material can cause fainting, respiratory problems, even death.
4. H2SO4 (sulfuric acid)
Sulfuric acid, H2SO4, is a mineral acid (inorganic) is strong. This substance is soluble in water in all comparisons. Sulfuric acid has many uses and is one of the main products of chemical industry. World production of sulfuric acid in 2001 was 165 million tons, with trade worth U.S. $ 8 million. Its main use of minerals including ore processing, chemical synthesis, wastewater processing and oil refining.
Sulfuric acid is formed naturally through oxidation of sulfide minerals such as iron sulfide. Water produced from the oxidation is very acidic and is referred to as acid mine drainage. This acidic water can dissolve metals present in sulfide ores, which will produce a toxic vapor brightly colored. Oxidation of iron sulfide pyrite by molecular oxygen get the highest iron (II), or Fe2 +
Potential Hazards:The properties of sulfuric acid is corrosive eksotermiknya exacerbated by the reaction with water. Sulfuric acid burns could potentially be worse than a burn caused by other strong acids, this is due to additional tissue damage due to dehydration and thermal damage secondary to the release of heat by the reaction of sulfuric acid with water.
Sulfuric acid is considered nontoxic but corrosive hazard. The main risk of the sulfuric acid is in contact with skin causes burns and smoke inhalation aerosol. Exposure to acid aerosols at high concentrations will cause irritation to eyes, respiratory tract and mucous membrane damage. The irritation will subside quickly after exposure, although there is a risk of pulmonary edema if tissue damage is more severe. At low concentrations, the symptoms caused by chronic exposure to sulfuric acid aerosols are the most commonly reported is the erosion of teeth. Indications Chronic respiratory damage remains unclear. In the United States, established permissible exposure limits as 1 mg / m³. There are also reports that sulfuric acid ingestion causes vitamin B12 deficiency with subacute combined degenarasi.
5. NaOH (Sodium Hydroxide / Soda Fire)
This compound is hygroscopic and absorb CO2.
Potential Hazards:Can damage body tissues.
Skin contact with NaOH.
6. NH3 (Ammonia)
Ammonia is a chemical compound with the formula NH3. Usually these compounds are found to be a gas with a distinctive acrid smell (called the smell of ammonia). Although ammonia has a significant contribution to the presence of nutrients in the earth, ammonia itself is a compound caustic and can damage health. Occupation Safety and Health Administration United States provides the limit of 15 minutes of contact with ammonia in the gas volume concentration 35 ppm, or 8 hours to 25 ppm by volume.
Potential hazards:Contact with high concentrations of ammonia gas can cause lung damage and even death. Although ammonia in the U.S. is regulated as non-flammable gas, ammonia is still classified as toxic by inhalation, and transport of ammonia amounted to greater than 3,500 gallons (13.248 L) must be accompanied by a written permit.
Inhalation of these compounds at high concentrations may cause respiratory swelling and shortness of breath. Exposed to ammonia at a concentration of 0.5% (v / v) for 30 minutes can cause blindness.
7. HCN (Cyanide Acid)
These compounds are highly toxic, even at one of the foods that we often eat the cassava that suffered damage. Symptoms of damage is characterized by the release of a dark blue color due to formation of cyanide that is toxic to humans. Cyanide acids also exist in the fruit heels in love.Heels in love, kluwek, keluwek, keluak, or kluak (Pangium edule Reinw. Ex Blume; Achariaceae tribe, formerly included in Flacourtiaceae) is a tree-shaped plants that grow wild or half wild. Sundanese people call picung or Pucung (as did most people in Central Java) and in Toraja called panarassan.
Keluwek seeds used as seasoning kitchen cooking Indonesia that gives color to black on rawon, meat seasoning kluwek, brongkos, as well as soup konro. The seeds, which have seeds that can be eaten salute, when crude is highly toxic because they contain cyanide in high concentrations. When eaten in a certain amount cause dizziness (drunk).Toxins in seeds can be used as a poison for arrowheads. These seeds safely processed for food when it has boiled and soaked first.Also there is an article who stated that Cyanide Acid (Hydrogen Cynide) used as a weapon of mass murder in Nazi-era Germany.
8. HF (Hydrofluoric Acid)
Hydrofluoric acid is highly corrosive acid, can dissolve many materials, especially oxides. The ability to dissolve the glass has been known since the 17th century, even before hydrofluoric acid has been prepared in large quantities by Carl Wilhelm Scheele in 1771. Due to the high reactivity of the glass and moderate reactivity of many metals, hydrofluoric acid is usually stored in plastic containers although polytetrafluoroethylene (PTFE) is slightly permeable.
Potential Hazards:hydrogen fluoride is initatif of skin tissue, damage lungs and cause pneumonia (respiratory disorders).
9. HNO3 (Nitric Acid)
Nitric acid, also known as Aqua Fortis is a substance that is very corrosive and is a highly toxic acid.
Potential Hazards:Can cause burns, inhaling vapors may cause death.
Burned skin due to exposure HNO3
A coin which is soluble in the liquid HNO3 in 31 seconds ..
