Disintegration

The container sustains a general loss of integrity, occurs in containers that are made of a brittle material

Runaway cracking

A crack develops in a container and continues to grow rapidly, Breaks the container into two or more relatively large pieces

Attachments open or break

May fail, open, or break off when subjected to stress, leading to a total failure of a container

Puncture

Occurs when foreign objects penetrate through a container

Split or tear

Containers may also breach through a split, such as a welded seam

Detonation

Instantaneous and explosive release of stored chemical energy of a hazardous material

Deflagration

An explosive release of stored chemical energy at a rate slower than the speed of sound

Violent rupture

Immediate release of chemical or mechanical energy caused by runaway cracks

Rapid relief

Fast release of a pressurized hazardous material through operating safety devices or damaged valves, damaged piping, damaged attachments, or holes in the container

Spill/leak

Slow release of a hazardous material through holes, rips, tears, or usual openings/ attachments.
