Hazardous Materials

Hazardous materials are substances which can endanger or damage in certain concentrations (amounts) people, animals, environment and real values.

These materials can be existent firmly, liquidly, gaseous or also in the form of radiation.

Appearance of hazardous materials
Different transport ways (streets, rails, water, air)
Storage, manufacturing, processing in buildings and mills
During fires as a result of the combustion (pyrolyse products)
Hospitals, indoor swimming pools, collecting points of problematic goods
Agriculture

Chemical materials
Caustic materials
Develop a direct irritation and caustic impact on eyes, skin and tissues of humans and animals.

Acids and bases (heavy caustic materials)
Cause corrosions of the eyes, the skin and the respiratory system as well as destroy clothes and equipment.

Materials which are harmful to the environment
Damage depending on their character and effect plants, soil, ground water and bodies of water.

Poisonous materials
Provoke the damage of blood, nerves or cells of humans and animals.

Nitrogen fertilizer
Decompose at temperatures > 130°C. In this process are generated nitrous gases and ammoniac gas.

Mineral oil products
Are harmful to the base water and can cause danger of fire and explosion depending on their character.

First aid at corrosions and toxication

Corrosion can caused by

Acids (e.g. sulphuric or hydrochloric acid)
Bases (e.g. sodium hydroxide, caustic portash) causes injuries on skin and mucous membranes, redness, blistering and sloughing.

Measures:

Flush injured body parts with a lot of water,
Flush eye injuries with running water.

Toxication
Measures:

Measures are limited to the survey of the vital functions,
Give the rest of the toxin, packaging or other indications on the kind of toxin to the emergency rescue service.

Hazadouse need chemical hazard symbol on their storage, in hazadous chemical storage.

Removing Iron Rust Using Electrochemical Process

One way to remove iron rust is by electrochemical process. The iron or metal that will be rusted is given a negative charge and the other electrode means that it is positively charged, so the rust will be released from the metal because negative ions will come out of the metal and go to the positive electrode. If the process is continued, the iron may become shiny, not because it is coated in therapy because the surface is partly faded. This is because the iron functions as a negative electrode, where the ions on the surface of the iron will decay and dissolve into the chemical solution. To give an idea of this process, see the following video:

Sodium Sulfite and Sodium Hydrosulfite

Sodium Sulfite Sodium sulfite is a compound that is very easily oxidized. For this reason, it is employed in many cases where a gentle reducing agent is desired, e.g. to bleach wool and silk, as an antichlor after the bleaching of yarns, textile and paper, as a preservative for foodstuffs, and to prevent raw sugar solution from colouring upon evaporation. It is very widely used in the preparation of photographic developer to prevent from oxidation from hydroquinone and other agents. It has a small application in the field of medicine as an antiseptic and as an antizymotic for internal use. About 60% of the total merchant market is in the paper Industries. While merchant capacity is about 145,000 t/year, the paper mills have twice capacity to captive use. The demand for boiler feed water treatment is about 15%. It is use to remove oxygen from water and thus help to prevent corrosion and scale formation. These were four major production in 1891, one of which provided 50% percent of the

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo
