blowout

A blowout is a sudden and uncontrolled release of pressure or contents from a container, vessel, or system. The term is used in several domains to describe different phenomena that share the core characteristic of rapid, often violent discharge, and is sometimes used metaphorically to describe a lopsided competition score.

In automotive contexts, a tire blowout occurs when a tire rapidly loses air, usually due to puncture, tread wear, impact damage, or improper inflation. It can cause loss of vehicle control, particularly at high speeds. Safety steps include easing off the accelerator, steering to maintain control, signaling, and moving to a safe area to inspect or replace the tire.

In the energy industry, an oil or gas well blowout is an uncontrolled release of fluids from a well, typically resulting from insufficient well control, high formation pressures, or equipment failure such as a blowout preventer. Consequences can include fires, explosions, and environmental damage. Prevention relies on careful well design, accurate mud weighting, proper cementing, and the reliable operation of surface and subsurface safety equipment. Response measures include containment, sealing, and capping the well, along with environmental cleanup.

Geologically or in geomorphology, a wind or water blowout is a depression formed by the rapid removal of loose surface material, such as sand or soil, by deflation or erosion. These features are common in deserts and beaches and can influence local drainage and vegetation.

In sports, a blowout refers to a game decided by a large margin, signaling a dominant performance by one side and a relatively one-sided contest.
