Burn and damage organic tissues

Caustic is defined as something that, due to its properties, can burn and damage organic tissues . The handling of caustic substances, therefore, is dangerous since contact of said products with the skin causes injuries .

For example: “Be careful with that cleaner because it is caustic: do not forget to use it with gloves” , “Disinfection is very important but you have to be careful with the caustic components” , “A caustic spill on the road put the authorities on alert ” .

Regarding their risks to humans, we can divide them into categories:

Something caustic, finally, is offensive , sarcastic or biting : “The caustic response of the interviewee made the journalist uncomfortable” , “I am fed up with your caustic comments and your constant irony” , “The artist's caustic sayings generated a great stir” .

In the first example, the nature of the words that the interviewee chooses to respond to the journalist manages to make him uncomfortable, since he uses daring language, which leaves the comfort zone expected by the media and manages to provoke a reaction . Sarcasm or bitingness in these cases can be very productive if it is used for a genuine purpose, such as fighting for a cause such as corruption, poverty or violence.
