Decoupling is a method of releasing the excess of pressure (occurring when an explosion happens) in a safe way to a safe location. It is enabled by employing safe vents. They are designed to open when a nominal pressure value is exceeded.
Vents dimensions have to be adequate to explosion strength in protected appliance: silo, tank, filter, cyclone, industrial vacuum cleaner.
A whole construction and vent/bursting disc are in accordance to VDI 3673 (EN 14491, nowadays) guideline.
