We explain to you what the chemical risk is, in what circumstances it is higher, what types exist and the characteristics of each one.
What is the chemical risk?
In chemistry, chemical risk or chemical hazard is understood as those conditions of potential harm or health caused by uncontrolled exposure to chemical agents of various kinds. In other words, it is about the danger that chemical compounds and chemical substances, capable of causing diseases, chronic effects or death, entail.
The severity of these risks depends on factors such as the nature of the chemical agents, their concentration, or the time and route of exposure to them.
It is not exaggerated, however, if it is affirmed that virtually every reactive chemical has a potential for change in the nature (chemical contamination) or in the organism of a living being, s What some will be more short-term harms and others, on the other hand, will be less immediate.
There is a potential chemical risk in jobs involving the handling of toxic substances, or in those that are underproduced and not properly managed, or in which personnel lack the minimum protections b Sicas
However, there is also a chemical risk in nature itself, since the dumping of chemical substances into the environment is carried out in alarming daily proportions. And not always nature can deal with them effectively and autonomously.

Types of chemical risk
The chemical risks can be diverse, depending on the effect they may have on living beings, particularly the human being. So, we talk about:
- Flammable Substances that react easily with the environment or with themselves after the injection of some energy, releasing very high amounts of heat, that is, caloric energy. Generally this is accompanied by the creation of flames, that is, of fire, capable of spreading to other materials.
- Explosives Materials that react quickly and violently to combustion, generating huge amounts of heat, light and kinetic energy (movement), either in a controlled and usable way, or uncontrolled and catastrophic.
- Oxidizers Substances capable of generating violent oxidation in flammable substances, that is, that can trigger fire or delay its extinction.
- Corrosive Those compounds endowed with a great capacity of oxide-reduction before organic matter, generating an exothermic and highly destructive reaction, capable of producing burns without the need for flame. Corrosive materials can oxidize metal or destroy organic tissues by contact.
- Irritants A lighter version of corrosives, capable of producing reversible lesions on human skin or mucous membranes, but not completely destroyed.
- Toxic These compounds have molecular properties that make them highly reactive with the organism, thus causing unpredictable effects on it.
- Radioactive These are athemically unstable substances, whose molecules emit particles (neutrons, protons, etc.) constantly as they decompose into another stable element. The emission of these particles can alter the genetic code and damage the tissues.
