FK-5-1-12 Novec 1230 AKA Halon

Fire Extinguisher MRI
Non-magnetic clean gas fire extinguisher
Nuclear magnetic resonance MRI fire extinguisher
Proton Therapy PT fire extinguisher
The main feature of AKA Halon non-magnetic fire extinguisher is non-magnetic,
The container material is made of non-magnetic stainless steel.
The use of fire extinguishing agent FK-5-1-12 is
an important substitute for halon fire extinguishing agent.
It is colorless, odorless, low-toxic, non-conductive, does not pollute the protected objects and
will not cause damage to property and precision facilities, nor
It will cause human and livestock hazards during use.
It can reliably extinguish Class A, B, C fires and Class E electrical fires
with a low extinguishing concentration, and it does not contain particles or oily residues after release.
No damage to the atmospheric ozone layer, ODP is 0
The global greenhouse effect potential GWP is 1
The retention time in the atmosphere is 5 days
which meets environmental protection requirements. AKA Halon Chihailong non-magnetic
fire extinguisher is specially designed for MRI... and other strong magnetic field environments.
The clean gas fire extinguishers developed have been widely used in large hospitals and
scientific research institutions at home and abroad.

AKA Halon FK-5-1-12 is no corrosive, has good insulating property, never damages electronic equipment, precision instruments, paper documents, cultural relics and antiques, generates no residue after use, and may substitute for sprinkler system, and dry chemical and foam extinguishing system to protect the high-valued assets.

FK-5-1-12 extinguishing agent has excellent extinguishing characteristics and it can put out Type A, B and C fire, is non-conductive and after ejection it fast evaporates without any residue. Its extinguishing concentration is 3.5% and 4.5% for Type A or Type B fire, which mostly approaches that of halon extinguishing agent.

Ozone Depletion Potential Of Zero
FK-5-1-12 clean extinguishing agent has good environmental harmony, and its Ozone Depletion Potential (ODP) is 0, Global Warming Potential (GWP) <1.0, and the Atmospheric life Time (ALT) is 0.014 year

Results of toxicity test of FK-5-1-12

Test item	Test result
4-hour acute inhalation	Almost no toxicity (LC50＞100000ppm)
Carcinogenicity	No carcinogenicity
Acute oral	Low (LD50＞5000mg/kg)
Acute dermal	Low (LD50＞2000mg/kg)
Irritation to eyes	No irritation
Irritation to skin	No irritation
Allergy to skin	Non-skin sensitizer
Chromosome aberration	Negative

From the above it is clear that FK-5-1-12 extinguishing agent ensures the extinguishing efficiency, meets the requirements on use safety, is almost
harmless to human body, and is much suitable for extinguishing and protection
of the person-residing place.
