Regarding to confined space, WHAT are names of the meters those are being used for measuring the fowling:

Go through the PDO's specification "SP-1125 Isolation of Process Equipment" and you'll find all the answers.

OK I thought you can get it from any of your elder colleagues - everyone in Oman uses Shell/PDO standards, I guess

Try the NORSOK standard and see if it can give you more insightful view into the subject: http://www.standard....134/P-001e5.pdf

You're still not sleeping? It's 1:30 AM in Oman - not a way to go if you're professional engineer waking up at 5AM.
