Letter “S” in model designation refers to “Switch” (integrated pressure switch). Letter “S-E” in model designation refers to “Switch
Economy”. More information about pressure switches are present below in this User Manual.
** Calculated at a 7 % (Electrical Fires) and 9 % (Engine Fires) design concentration at an ambient temperature of 20 °C (68 °F) for the
enclosure. Please note if a lower temperature is present the coverage potential will be reduced, please contact your local BlazeCut agent
for further information.
COMPONENTS OF THE SYSTEM AND THEIR DESCRIPTION
Extinguishing agent
Type of extinguishing agent: HFC-227ea
Chemical name: 1,1,1,2,3,3,3-Heptafluoropropane
Extinguishing agent is clean extinguishing medium, used in the BlazeCut
T Series for volume fire suppression. Extinguishing effects are due to cooling
and anticatalyst effect. Extinguishing agent siphons heat from fire, enters the
chain chemical reaction of burning, slows this reaction and stops it.
Extinguishing agent is not toxic or poisonous, it does not have carcinogenic
or mutagenic effects and it is considered environmentally accepted
substitute for halon extinguishing agents.
General characteristic: liquefied gas, colourless, odourless
GWP: 3220
Although the extinguishing agent is not toxic or poisonous, unnecessary excessive exposure of persons to its influence should
be avoided. Under no circumstances should persons be exposed to the extinguishing agent for more than 5 minutes also in
case when the extinguishing concentration does not exceed the LOAEL level (contact your local BlazeCut supplier for more
information).
During the system activation the extinguishing agent is discharged from the tube under high pressure and at very low
temperature. No permanent work place should be placed less than 1 meter (3.28 feet) from the system if the system is not
installed in enclosure that prevents the extinguishing agent being discharged onto the people or no other barriers are in place
preventing the extinguishing agent being discharged onto the people.
If people are constantly present in the protected area, always consult the use of the system with the supplier. The system must
be designed so that when the extinguishing agent is released the extinguishing concentration level, which could be dangerous
to people, is not exceeded.
Extinguishing agent under normal (atmospheric) pressure evaporates quickly. Do not breathe vapours. Exposure to high
concentrations may cause health problems: a temporary loss of nerve activity, numbness, dizziness, confusion, loss of
coordination, drowsiness, unconsciousness, irregular heartbeat, palpitations, depression, fainting, weakness. Exposure to
extreme concentrations of extinguishing agent may cause death without warning.
Extinguishing agent in liquid form may cause frostbite upon contact with eyes. Avoid contact of liquid extinguishing agent with
eyes. For installation, inspection, maintenance and repair of the system always use eye protection - wear appropriate protective
glasses with side-shields.
Extinguishing agent in liquid form may cause frostbite upon contact with skin. When leak of liquid extinguishing agent from the
system is detected use appropriate protective impervious working gloves.
Extinguishing agent is subject to thermal decomposition and forms toxic products - hydrogen halides after long exposure to high
temperatures in the fire area. Avoid prolonged exposure of extinguishing agent to high temperatures. After fire is indicated take
HFC-227ea Extinguishing Agent is
UL Recognized and FM Approved
