Silo collapses from stressed structural weld

Information:

A silo containing 300,000 litres of milk collapsed at a dairy co-op factory recently.

The collapsed occurred after the dome bottom tore away, causing a large hole in the silo. The contents then rapidly discharged, creating a negative pressure which sucked in the upper ‘barrel’ and subsequently collapsed the silo.

Fortunately no one was injured.

Following the collapse, the factory conducted a visual inspection of all other silos and found minor to severe cracking to the structural welds.
