could you complete this table?
Utility :

What's the risk of each utility and how do you prevent a hazardous situation for each utility?

Plant Air
Instrument Air
Nitrogen
Sea water(cooling water)
Service Water
Deminerlised water
Potable water
LP Steam and Condensate
High Pressure steam

Betty,

Welcome to the forum. First of all, it is not clear what do you mean by terms "risk of each utility", and "hazardous situation" for each utility.

From the plant/personnel point of view, utility systems are considered to be completely harmless, and they are usually located within the "green zone" areas in the plant. If you look at fire/explosion and toxicity risk levels associated with utility systems, you'll find them to be essentially zero.

I hope you'll get more detailed answer from an experienced risk/safety engineer (e.g. Guido), and you should also put some more efforts from your side and clarify the question you've just posted.

[betty]

yeah, I'll clarify. E.G., Plant air will contains some particles that are not filtered, so by this way may be will effect on the equipment after long time.

did you get what i want >>?

Betty:

I would like to help you - but I can't identify what you really need. Do you need an explanation behind these utilities - or do you just need answers to turn in as a response to a class assignment?

You have failed to "clarify" why it is that if you can identify the risks behind the use of plant air, why is it that you can't also do the same logic and review of all the other subjects.

Obviously you did some original, specific thinking on the subject of plant air. You certainly can duplicate the effort for each of the other eight subjects you list. This exercise is not meant for OUR benefit. It is meant for YOUR benefit. However, there can be no benefit to you if you don't honestly put some personal, dedicated work effort into the assignment. That's the whole nature and logic of the assignment: to force you to use your own initiative and thinking in solving problems that will confront you in your future career as a professional engineer.

YOU are supposed to meditate, think, concentrate, or conjutate on the problem at hand and use your logic and knowledge to come up with what you can identify as potential hazards caused by the need or use of these utilities. If we dedicate our work effort to detailing the answers for you (which, I can assure you we can do in great detail), what will you really gain from our effort? You may get a good grade ---- but you certainly will not have learned anything from the process and will continue on to become an ineffective and useless engineer that probably won't be hirable .

I think, believe, and hope that you should do the mental and research work involved instead of relying on us to do it for you. Such is the life of an engineering student. You have to prove to others that you can think for yourself.

dear Mr: thankyou for your replaying>>>>(I would like to help you - but I can't identify what you really need. Do you need an explanation behind these utilities - or do you just need answers to turn in as a response to a class assignment?)

Believe me I'm uderstanding you and as you said >>I need an explanation behind these utilities
if you don't mind and I think this will be one my key to build my asnswers!!!

Thanks

No, betty, we did NOT get what is needed to supply you with a meaningful answer. That is what Mr. Montemayor has tried to tell you. You have a knowledgable, helpful audience "out there" that would be happy to assist you. BUT, you must assist us by formulating direct, succinct, meaningful questions that clearly indicate your needs and adequately supply all that the reader needs to develop a response. When you don't get a response, then either no one knows the answer (which is unlikely IF you have correctly identified your topic), or you have failed to meet the criteria stated above.

With your most general inquiry, all you can expect is a very general response. So, what are the hazards? Well, you might have high temperatures, high pressures, substances that could exclude oxygen, etc. That's about all I can say given the information you have provided.

Also, it is normally understood that hazardous = dangerous to humans. The above statement suggests that you are asking about possible erosive behavior to equipment. What is it?

Dear betty Hello/Good afternoon
I re-iterate a phrase referred by my deceased father(basically a teacher by profession)
Almost 'half of the answer is present in the question itself'

Your question(s) still remain vague and as such nobody can help.

Please do clarify what particular hazards,Risks associated with each of the querried utility you would like to control or eliminate

Everyone is ready to come forward with help;kindly do your part urgently.
Regards

Are you looking to be spoon fed answers here?

I agree with the other contributors that you need to help yourself, do some work and provide the forum with some specifics.

However, (and I'm taking a guess at what you're after) if you're trying to rank the hazard level associated with the various utilities that you've listed, then I would suggest that you help yourself by approaching it from a quantitative / engineering perspective.

How about you tabulate the various relevant properties that these fluids exhibit?

As mentioned previously, pressure and temperature are the 2 hazard parameters that readily come to mind. Then you could consider flammability and toxicity. You've mentioned contaminants already, so you could include that in your table.

Hopefully that gives you a start. The hard work is up to you.
