Hi
Recently I was visiting a power station and someone mentioned there were new requirements by NFPA 20 for pumps to be physically separated from each other by a wall. I've never seen this anywhere. I read through NFPA 20 and did not find anything regarding this matter.
Could someone please...
The answer might seem obvious to some of you but this is the first time I've faced a fire protection system installation like this (without a pump), so please bear with me.
The question in the thread title (which I had to summarize due to lenght constraints)is regarding the annual performance...
I'll start by saying that I am very familiar of physicochemical analysis of oil for different rotating equipment such as turbines and pumps, but the case I have now is a large size pump that uses grease for lubrication, not oil but just grease.
So I was wondering if someone could recommend if...
Hi
I think to remember that plastic or rubber hoses (maybe they are called tubes or pipes) used to "read" the fuel level of the motor of a fire pump are not allowed. Am I right? If so, could someone please tell me the code (and paragraph if possible) where this is forbidden?
Hi
Last week I read about the University of Stavanger in Norway running a gas turbine purely on hydrogen but despite the several artickes I checked, none mentioned the power of the turbine and the ones that gave more information about tbis issue, said it was a micro turbine.
Does anyone have...
Hi
Someone mentioned to me that in seismic activity prone areas, battery banks should have a type of "wedge" (sorry if this is not the right word in English) between the first and the last batteries and their corresponding sides of the frame to prevent that in case of an earthquake, the...
Hi,
In my job as a loss control engineer for an insurance company I come across different turbines, some are well known and some I've never heard of them before and determining if that specific series has been in operation for enough time is key to my analysis. So my question is if there is...
Hi
I understand that the criteria to consider a relatively new combustion turbine as proven may differ from a manufacturer to another, but I guess there should be at least some minimum requirements, so is there a list somewhere where you can check if a specific CT is considered as proven...
NFPA 33 allows sprinkler heads inside spray booths to be covered by thin cellophane bags to prevernt them from being splashed with paint which would make them useless.
Does this refer to water sprinkler heads only or could heads from a gaseous agent extinguishing system that meets all...
Hi
During a recent risk inspection visit to a soft drink manufacturing plant where ammonia is used, someone mentioned that vent pipelines should not vent to the atmosphere but to a vessel containing water to avoid the creation of an ammonia cloud. Is this true? If so, what code recommends this?
Hi
I couldn't find a forum dedicated to gas, so i thought this would be the right one to post my question but if it isn't I apologize in advance.
I'm a loss control engineer working for the insurance industry where the NFPA codes are the most common, but for this specific question I think...
According to the large amount of information on the web about hydropneumatic tanks and their large use in industrial hydraulic applications I got to wonder, why is it that fire systems (for sprinklers and/or hoses) do not use them? Is there a dissadvantage if one would use them?
I know that connecting lamps with flexible cable is not a good practice according to NEC, but why is it?
Why the lamps of a warehouse located way above circulation paths, shouldn't be wired like that?

Hi
What could be used as fire protection in a tunnel under construction? I guess portable extinguishers, but how far apart should they be placed and how do you fix extinguishers to solid rock?
The tunnel is for a hydroelectric plant, so the tunnel will be filled with water once the plant...
Hi
I know this isn't exactly a civil engineering question, but maybe some of you have faced a situation like this and could help me.
There is this company that is doing some civil works on a street right in front of inhabited houses. The work consists in installing new pipes for the sewage...
Hi
There is this company that is doing some civil works on a street right in front of inhabited houses. The work consists in installing new pipes for the sewage system so it takes a couple of months and meanwhile, the people that inhabit the houses have to put up with it. There have been a few...
I'm aware of the distances for emegency exits required by NFPA 101, but what if a large warehouse (295 ft -90 m- long) has other warehouses (of different applications and owners) on all its sides except for the front? How can you comply with emergency exit distances when they can only be located...
When reviewing any standpipe system I've followed the 500 gpm @ 100 psi for 2 ½” hoses and 100 gpm @ 65 psi for 1 ½” hoses, which gives a 15.000 gallon tank for the half hour (at maximum demand) it should provide while the firefighters arrive.
This week someone mentioned to me that in NFPA 14...
What fire protection system can be installed in a large (2.500 m2 - 27.000 ft2) storage warehouse where the only product is quicklime in big bags, since quicklime produces a violent exothermic reaction when in contact with water and in such a large area an extinguishing gas would be unthinkable...
