4.5.5.3.(1)

Intent 1:

To limit the probability that flanged joints in piping will fail, which could lead to the escape of liquid, which could lead to the accumulation and subsequent ignition of vapour from a nearby ignition source, which could lead to damage to the building or facility.

Intent 2:

To limit the probability that liquid will escape through flanged joints in piping , which could lead to the escape of liquid, which could lead to the accumulation and subsequent ignition of vapour from a nearby ignition source, which could lead to damage to the building or facility.

Intent 3:

To limit the probability that the flanged joints will not be of sufficient design which will lead to premature failure of the joint, which could lead to the escape of liquid, which could lead to the ignition of vapour from a nearby ignition source, which could lead to damage to the building or facility.

Intent 4:

This is to limit the probability that internal stress, or mechanical damage will lead to failure of the joint which could lead to the escape of liquid, which could lead to the ignition of vapour from a nearby ignition source, which could lead to damage to the building or facility
