[SystemSafety] LOPA

[paul_e.bennett at topmail.co.uk]

While the rest of you are being so quiet, I thought I would drop a
link to the video I saw recently. I know it is about a year old and the
event was more than two years ago, but I figured it would be of
interest here.

It seems that the catalyst  only had a single means of stopping its flow,
and its being eroded reduced its effectiveness. One might wonder why
a second slide valve in series, only used for shutdowns, was not thought
to be a useful protection measure that might have prevented the disaster.

How many think of doing a LOPA for the software they write? The adding
of definitive protective containments.
