海龍滅火器全氟己酮 FK-5-1-12 全氟-2-甲基-3-戊酮 756-13-8 C6F12O Fire Extingguisher 3M Novec1230 全氟己酮滅火器

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.
