I have contacted Firepro which is making UL listed Aerosol units and asked them
the below questions, I would appreciate your comments on their answers:
1- According to NFPA 2010 "Aerosol fire-extinguishing agents shall not be used
on fires involving Deep-seated fires in Class A materials", then do you offer
Firepro units to be used in Paper/Book Archive Rooms facing deep seated fire in
class A material?
ANSWER: All fixed gas extinguishing systems, as well as aerosol systems are
tested and certified for Class A, surface burning fires. The test protocols for
polymeric materials and wood specify pre-burning times from 3.5 min. to 6 min.
respectively. Longer burning time is considered as deep seated fires.
2- According to NFPA 2010 "The potential adverse effects of agent particulate
residue on sensitive equipment shall be considered", then do you offer Firepro
units to be used in Server Rooms with sensitive hard disks.
ANSWER: FirePro has been independently tested by NLR (Dutch National Aerospace
Laboratory) and TNO (Netherlands Organisation for Applied Scientific Research),
proving that there are no effects on (a) corrosion of sensitive electrical
components, and (b) the operation of electrical equipment, respectively.
3- According to NFPA 2010 "aerosol systems shall be used in normally unoccupied
areas because of visibility obscuration and the potential health effects of
accidental exposure to the agent" then do you offer Firepro units to be used
in Monitoring Rooms where people usually exist?
ANSWER: Please see detailed response

4- Do you offer Firepro units to be in a place where dust or residue is a
matter of concern and clean-up procedure costs too much like a museum, art
gallery?
ANSWER: Please note, after a fire, there is a huge mess, Therefore, after a
fire, you are going to clean anyway ! FirePro has been used in museums and old
cultural buildings, etc, the consequences of other extinguishing agents such
as halocarbons, especially in electrical/electronic applications, can be more
serious; of paramount importance is the liberation/formation of HF (hydrogen
fluoride) and CO at high temperatures. So it is best to sweep/dust the FP
particles than to damage/destroy the electrical components with the
decomposition of halocarbons/FM-200.
Best,
Reza
