I saw a sprinkler system with only water for an identified oil risk (lubricating oil). Quite weird, no? The identified risk concerns oil contained in a pump. This pump circulates a fluid at high temperatures. I'm not sure, but it should be about 20 liters.
1) Do we have to use WATER+EMULSOR or WATER only is OK?
Moreover (I take advantage of the generous soul who will be able to answer the previous question) :
2) Is there a minimum oil quantity threshold from which a sprinkler system is necessary?
3) What is the required spray density for oil risk?
4) What is the surface to consider : the entire room, the retention or the projected pump surface on the floor?
I would like to thank in advance the person who can answer me.
