Problems with human health harmful substances are chemical elements known as persistent organic pollutants (POP)
They are found in the environment because they are used by different manufacturing and agricultural sectors.
These harmful substances are listed as \"priority lists\" because they often pose the most potential threat to the environment and human health.
Threat issues mean constant exposure or prevalence in the atmosphere, causing harm to human health and wildlife, polluting water and its sources, and polluting air and soil.
Therefore, employers and workers are advised to understand the different types of hazardous substances used to control, prevent and avoid.
They are divided into four types: corrosive, flammable or flammable, reactive or flammable and toxic.
As toxic and harmful substances, they are further classified as narcotic drugs, asphyxi agents, sensitizers, carcinogens, mutators and hallucinators.
Corrosive harmful substances are considered corrosive substances, if they are able to eat through metal when in contact, burn the skin of a human or animal, and emit steam or smoke that can be applied to the eye
Examples of corrosive harmful substances are: fluorine against monic acid-this is also known as super acid because of its strength and its ability to burn anything, including substances that should not react with acid.
It is a mixture of antimony pentfluoride and hydrogen fluoride.
According to the study, it is said that it is 20 times more powerful than sulfuric acid.
This super acid can be found in industries that require chemical reactions to achieve transformation, just like refining crude oil into high acid.
The process of converting oil shale into crude oil.
They can also be found in the plastic manufacturing industry.
Hydrochloric acid-commercially known as muriatic acid, is considered one of the most common and important compounds in manufacturing.
Hydrochloric acid is a chlorine gas that burns in hydrogen to produce hydrogen chloride (HCl).
When HCl is combined with water, hydrogen ions are released to form hydrochloric acid and can be commercially divided into two grades;
Technical grade with concentration of 35-
38% and commercial grade known as muriatic acid with a concentration of 30-32%.
In industry, the technical grade is used for metal, electroplating, activation of geothermal oil wells, processing of electronic products, and manufacture of fertilizers and dyes.
In the food industry, HCl is used to process starch, glucose and protein.
Muriatic acid is widely used in the home as an effective defacing agent for floor tiles and other kitchen and bathroom fixtures.
Sulfuric acid-this substance is also known as sulfuric acid or sulfuric acid oil for industrial processing by dissolving sulfur dioxide in water.
Once the saturation point is reached, it becomes a smoke-generating sulfuric acid known as smoke-generating sulfuric acid for processing other organic chemicals.
Sulfuric acid is also considered to be one of the most important chemicals in the industrial sector for manufacturing dyes, pigments, fertilizers, detergents, explosives, inorganic salts and acids.
It is also the main acid in lead.
Acid battery.
There are other uses in the petroleum refining industry and metallurgical processing.
Nitric acid-this harmful substance is highly corrosive and can have the properties of smoke corrosive liquids, which are considered inorganic compounds.
Its importance can be found in industries such as fertilizer and explosive manufacturing and spent fuel reprocessing.
Used for steel etching and photographic engraving.
For descriptions of our environment of other types of hazardous substances, please go to the next page.
Flammable/flammable if a hazardous substance is prone to combustion and has certain properties of a fire hazard, it is considered flammable or flammable.
When an aerosol produces a flame projection of more than 18 inch, the aerosol is considered flammable when subjected to a test method called 16 CFR 1500 45, which opens the entire valve.
Some liquid substances can be flammable by having a flash point at 100 degrees Fahrenheit, while some flammable liquids are a mixture with a flash point of 141 degrees Fahrenheit or higher.
Gasoline and solvents can easily be identified as flammable and harmful substances, but you may not know that some foods, metal dust and wood also have flammable ingredients.
If there are three elements, a substance is flammable or becomes flammable: oxygen, fuel, and firearms, such as the form of heat.
Keep in mind that oxygen always exists because it always exists in the atmosphere.
The ignition will provide the spark that causes the fire, while the fuel will keep the flame burning.
Examples of ignition are sparks, open flames, static electricity, friction, heat, welding arc, cigarette butts with residual fire, indicator lights and similar ignition sources.
As you guide, flammable substances such as gasoline, acetone, ammonia, ethylene oxide and pentane are all liquid dangerous substances;
Acetylene, propane, carbon monoxide are in the form of gas, while solids such as rubber, plastics, wood, packaging, textiles, plastic foam, wood dust, sugar dust and surface dust are also flammable.
In the event of a fire or explosion, use a thick blanket or non immediately
Flammable materials for the removal of oxygen, as the fire cannot last without such elements.
When active or combustible hazardous substances are combined with another chemical, there is a tendency to form toxic gases or explosions.
A good example is chlorine bleach, which, if combined with ammonia, produces an active substance and a toxic substance.
Other examples of reactive or combustible hazardous substances are flax seed oil as a paint ingredient, oily cotton waste, carbon, copra and white phosphorus, which react when it comes in contact with air.
Some chemicals are known to be water.
Active substances such as alkaline metal, alkaline earth metal, anhydrides, hydrides, insurance powder and phosphorus aluminum.
It is important for workers to understand water.
Activity and air
The reactive materials they are dealing with may even include combustible cleaning materials.
They should be avoided from being stored in a damp environment or ensuring that they are kept in compatible containers with equal strength.
The learning of these waters
Reactive combustible materials are also important to avoid water use when trying to put out a fire.
It is a safe choice to use a suitable class D fire extinguisher.
Toxic toxic organic pollutants have become widespread and diverse;
Therefore, the example given below is based on the way they are toxic or toxic behavior.
This is important especially in the workplace or occupation involving printing, paint, coating and paint or coating manufacturing, skim, dry cleaning, dye workers, in the application of glue and similar solvents, carpentry, textile manufacturing, aircraft modification, refining and the treatment of polymers, medicines and agricultural products.
Here is the son
Classification of toxic substances: anesthesia/deification
Sensitivity/paraly-this means that toxic or harmful substances can cause numbness and thus damage physical and mental function. De-
Sensitive substances usually exist like n-
Hexane, tinone and sulfur-dioxide carbon.
Choking-the most common choking is carbon monoxide, which can cause blockages that hinder the exchange of oxygen in the body.
Another most common example is the combination of bleach and ammonia, where oxygen replacement can cause discomfort in the respiratory system.
Sensitizer is a harmful substance that can cause allergic reactions such as formaldehyde, algae killer and similar biological agents, bread yeast and isocyanate.
Foam products.
These toxins are also present in spores, mold and mildew because they contain mycotoxins, and their severity affects people who are not allergic.
Since mold spores come from volatile organic compounds, they may appear on your wall (VOC)
Or exposed to materials that promote the growth of spores or molds at high humidity that produces moisture.

Continue to describe toxic and harmful substances carcinogens-are carcinogens found in asbestos, cigarette smoke, genetically modified foods, benzene, and other substances labeled risk indicator R40, r45 or r49.
The most common carcinogens can be found in workplaces, consumer goods, pet products and even food.
Examples of carcinogenic chemicals and substances are formaldehyde, which is usually encountered as an ingredient in a toilet cleaner, usually found in a dry environment.
Cleaning solution for pesticide composition, carpet cleaner and freckle remover, dichlordiphenol acetate and Sodium 2, Army price product No. 15, FD & C Red No. 40, fluorine phenol, and tobacco or cigarette smoke and smoke and many other chemicals. Mutagens-
Is a substance that can change the structure or composition of cells or DNA, which may be composed of x-
Rays, cosmic rays, gamma rays, and ultraviolet rays.
The mutagen is different from the carcinogens because some mutagen does not cause human cancer and only animal cancer.
They usually cause free radicals in the cells, causing DNA damage.
However, it is scientifically observed that DNA is constantly destroyed, but it can also be repaired. Teratogens-
These substances are called feto-
Toxic substances.
They affect the fertility of men and women because they affect sperm or eggs.
Prevention or care should be taken not only during pregnancy or breastfeeding, but even before the reproductive and fertility stages of the child.
These substances should be properly labeled and clearly marked with the following indicators: R60 (
Damage to fertility); R61 (
Hurting unborn children); R62 (
Risk of declining fertility rate); R63 (
May cause harm to unborn children)and R64 (
May cause harm through the way of the breastfeeding).
For example, in half-
Manufacture or repair of paint in conductor industry.
Vinyl chloride, PX, toluene, styrene, acetone, benzene and sub-methane chloride, ethanol and ethanol are only a few organic and inorganic chemicals considered to be hallucinogenic agents in industrial workplaces.
The database used to verify information on toxic and hazardous substances is clear that the list of types of hazardous substances is long but still incomplete.
If you need to study or verify certain chemicals, the tools you can use are from the Environmental Protection Agency (EPA’s)
Toxic reference database (ToxRefDB).
