BLEVE:
Just spent the day reviewing a basis of safety document setting out a rationale as to why DSEAR does not apply to the internal enclosure of an automated machine.

The written report was produced from a highly reputable international organisation authored and subjected to an internal technical review prior to issue.

The report examines the use of two substances Acetonitrile and Methanol, each with different surface areas and logically this has an affect on anticipated evaporation rates.

The report goes on the state that "based on saturated vapour pressure" the basis of safety will consider acetonitrile as the vapour release from this agent is greater than that of methanol.

On closer examination of the report, it is noted that the author had used the Psat applicable to methanol for the Acetonitrile this along with a multiple of other errors in the accompanying calculations has resulted in anything other than a basis of safety.

Interestingly, this report had been commisioned and reviewed by the equipment manufacturer, the client and others.....should make for an interesting meeting as the kit is in transit.

Goes to show that technical reports etc can be seriously flawed.

CivvyFSO:
Ever seen a fire engineering strategy?

I have not yet seen one that is not seriously faulted in some way or another, and the first draft is often a particular worry.

BLEVE:
Seen a few and written a few ;)Hopefully you are not talking about mine  :D

Tom Sutton:
Come back Kurnal all is forgiven.

BLEVE:
Can you imagine submitting a fire strategy doc to Civvy

Now that makes me smile

How lucky are we that we still have fire Certs
