I am a fire sprinkler fitter a military installation. Have a question regarding low expansion foam systems with the use of Viking Grate nozzles.
Of course with the concerns of AFFF, there are many issues and decisions flying around about the existing systems we have out here in our aircraft hangars.
Is it acceptable to use the Viking grate nozzles without the low expansion foam?
How does this provide any fire protection?
Obviously, this is not how the system was designed, in my opinion.
Please help me understand how this can be acceptable. I appreciate any and all input.
