Dear Sir, Madam:

Is there a specification on Fire Water? I checked NFPA; however, there is no clear specification. I want to know if it possible to use river water as Fire Water or if some type of treatment is required. I want to know the quantified specifications (Total Dissolved Solid, PH, Conductivity...)

Dear Ghasem.

In my experience in the design of fire water systems I have seen in several plants that water quality is not a big issue.

For example, some refineries use river water and ohter uses sea water for fire suppresion. The only treatment that I saw was filters with differtent mesh at the pump's inlet basin or piping to ensure no solids in the water. This is valid for a system that takes water from a contunouos source (like rivers or sea bays), but if you have to store water in a tank for fire purposes, consider to use fresh water with no solids.

Another topic are the materials of the equipment and piping/valves according the fluid handling. You have to compare costs of use corrosion resistant materials or use treated water.

I hope that this will be useful for you.

Dear Ghasem

I don't know about any Fire Fighting experience/witnessing the Fire fight on your part.
However my Consideration of 'Fire'[/color] in a petroleum, petrochemical, phamaceutical, food or other industries is 'A final unfortunate result after all the preventive/protective systems failure usually to a great extent' and it is an extremely emergent condition.

In most cases the on-site fire water resource may run-out, thereafter any type of ample water supply resource becomes MANDATORY TO USE [color="#006400"] for the sake of survival/ Fire extiguishment.

Hope this explains in very general terms the concept about fire water type in emergency situations.

Hi
in plants, Fresh (Desalinated) water with back up by sea water is provided as FIRE WATER
you can see in IPS IPS-E-PR- 310 section 7.1.7.4 & 7.1.7.5 as a reference
