An over-pressurization of a container is an example of which type of explosion?

An over-pressurization of a container is classified as a mechanical explosion. This type of explosion occurs when a container that holds pressurized materials becomes unable to withstand the internal pressure, typically resulting in a rupture or catastrophic failure of the container. Mechanical explosions are often characterized by the physical and structural failure of the vessel due to the forces acting upon it, such as pressure buildup beyond safe limits.

In this case, the explosion is driven by mechanical stress rather than a chemical reaction, such as in a chemical explosion where a sudden and rapid reaction between substances generates gases and heat, or in a nuclear explosion that results from nuclear reactions releasing vast amounts of energy. Electrical explosions involve electrical energy leading to an explosive event, which is distinctly different from the physical rupture of a container due to pressurization. Such clear distinctions help identify the nature of the explosion based on the underlying mechanisms involved.
