Gerzayn:
I would firstly determine if these are miscible or not.
Get samples, at least 100 mL, and mix with water; observe and decide.
If these are pure oils and extracts, they will be immiscible.
No way of knowing the oil/extract concentrations unless you ask or
obtain samples.
Flammable liquids presented as pure oils or extracts in plastic
containers are a REAL fire hazard.
I am not looking up the exact protection criteria, so I don't know
precisely, but it will be serious.
Miscible liquid protection is usually a bit downgraded from that for
immiscible, if that is what
0.6 gpm/sq. ft poses as.
Get the best quality foam that you can. Citrus oil probably has acetates,
which are polar. If there
are a lot of acetates, you are going to want to deliver the foam onto
the surface as gently as you
can. That means your kind of screwed for optimal "soft-application"
from an automatic overhead
discharge system. Specify a QUALITY alcohol-resistant foam. A
quality foam can last 20 years, and knock down a pool
fire with no more than 0.1 gpm/sq. ft. Include in the bladder tank
capacity, half again as much
foam as prescribed for extinguishment, to control the room during
overhaul.
I would also specify at least a couple a 100-lb dry chemical extinguisher.
Otherwise, if it is a spill fire
without dry chem, you may be waiting until the upper containers burn
down before the foam starts to work.
I would have a full forward-flow test header, and a drainage and clean-up
plan.
