CO2  -­‐  The  VersaEle  Agent  

•  Stored  as  a  liquid  -  CO2  is  stored  as  liquid,  under  pressure.      

-  When  a  system  is  acEvated,  the  liquid  CO2  flows  through  discharge  pipe  work  to  specially  designed  nozzles.    

•  Quick  VaporizaEon  -  The  agent’s  low  boiling  point  means  that  

the  liquid  vaporizes  rapidly  during  the  discharge,  providing  a  penetraEve  three-­‐dimensional  acEon.

CO2  -­‐  The  VersaEle  Agent  

•  Reaches  difficult  areas  -  The  rapid  expansion  of  the  gaseous  agent  allows  

fires  to  be  targeted  even  in  the  most  inaccessible  areas  of  the  risk.  

•  Fights  fire  on  two  fronts  -  Reduces  Oxygen:    Fire  is  exEnguished  by  reducing  

the  oxygen  level  in  the  risk  area  to  the  point  where  combusEon  cannot  be  sustained.  

-  Cools  Area:    Cooling  is  a  secondary  acEon  of  the  agent;  this  feature  is  used  in  local  applicaEons  where  the  liquid  phase  of  the  discharge  is  applied  directly  to  the  fire  and  risk  materials.

CO2  -­‐  Fast  &  Efficient  

•  CO2  is  fast  and  efficient  -  The  High  Pressure  CO2  system  uses  a  large  bore  

discharge  valve,enabling  high  mass  flow  rates  to  be  achieved.      

-  The  fast  acEon  of  the  control  system  and  valve  enables  the  system  to  react  within  the  first  few  seconds  of  a  fire  that  can  make  the  difference  between  a  nuisance  and  a  disaster.

CO2  -­‐  A  Clean  Agent  

•  CO2  clean:  -  CO2  is  a  colorless,  odorless,  dry,  inert  gas  and  is  

one  of  the  most  familiar  of  all  chemicals.      

•  No  residue:  -  AXer  exEnguishing  a  fire  it  vaporizes  fully  leaving  

no  residue.    There  is  no  mess,  nothing  to  clear  up,  no  water  damage.      

•  Safe  to  use  on  food:  -  It  is  non-­‐corrosive  and  will  not  contaminate  

foodstuffs.      

ROC Public: Green

CO2  -­‐  A  Clean  Agent  

•  Safe  for  electrical  fires:  -  It  is  non-­‐conducEve  and  so  can  be  used  on  

energized  electrical  equipment.

CO2  -­‐  Over  60  years  of  Experience  

•  Engineers  developed  carbon  dioxide  fire  ex5nguishing  over  60  years  ago  and  Kidde  have  been  responsible  for  every  major  improvement  that  has  been  made  in  this  branch  of  fire  protec5on.    

•  Exis5ng  Products  benefit  from  the  accumulated  experience  of  thousands  of  installa5ons  in  power  plants,  industrial  plants,  oil  refineries,  electronic  processes,  on  ships  and  in  a  wide  variety  of  hazardous  areas.  

ROC Public: Green

CO2  is  Low  Cost  

•  Carbon  dioxide  is  a  standard  commercial  product  with  many  other  uses  and  it  is  readily  available  throughout  the  world.      

•  Because  of  its  universal  use  it  can  be  obtained  cheaply  and  this  is  an  important  considera5on  when  frequent  recharging  of  storage  containers  is  necessary  as  in  local  applica5on  systems,  where  fires  may  be  more  frequent.

•  Safe  alterna5ve  to  CO2  

•  CO2  has  impact  on  central  nervous  system  and  heart  func5oning  

•  Normal  air  has  less  than  0.1%  CO2,  normal  breathing  rate  25-­‐30/min  

•  0.5%  is  the  safe  limit  for  spaces  occupied  for  less  than  8  hours  

•  Increase  to  3%  doubles  the  normal  breathing  rate,  causes  headache  

•  12%  consistency  causes  loss  of  consciousness  rapidly  and  death  in  a  couple  of  minutes  

•  CO2  fire  protec5on  systems’  consistency  is  min.  34%,  and  this  consistency  should  be  aTained  within  one  minute  (re.  NFPA  12),  and  maintained  over  the  en5re  protec5on  5me  (10-­‐40  minutes).
