<h3>What is a chemical?</h3>

A chemical substance is a chemical compound resulting from the union of two or more chemical elements. Compounds have different uses depending on their properties. However, some can be harmful and life-threatening to humans.

<h3>Potential acute effects.</h3>

The potential acute effects of some compounds may be related to skin contact causing:

Inflammation
Redness
Rash
Burns
Dry
Among other.

On the other hand, the chronic effects of chemical compounds can be:

Diseases in the central nervous system.
Respiratory diseases.
Skin diseases.
Degenerative diseases of the bone system.

<h3>What to do when a chemical is ingested?</h3>

There are a large number of chemical substances and each one has different properties. Therefore, it is very difficult to generalize about a treatment in case of ingestion. What must be done is to know the level of risk of the substance that is being handled and avoid ingesting it at all costs. However, if it is ingested, go to the emergency room.

<h3>Product flammability</h3>

Not all chemical compounds have the same flammable response to fire. Due to the above, it is necessary to identify if the substance that we are handling is highly or slightly flammable, for this we can consult the manual of the substance or the label of its packaging.

<h3>3 Chemical that produces a potentially dangerous reaction with hydrochloric acid.</h3>
