CO2 extinguisher have a max test pressure of 20,700 kPa. Max design operating pressure of 18,570 kPa. The min burst pressure of a cylinder must be at least 2.7 times the max operating pressure. So the burst pressure of a CO2 fire extinguisher will be at least 50,139 kPa
When it comes to fire extinguishes, the smaller the volume of the extinguisher the more pressure the gas has. So if the size of the fire extinguisher is small, the pressure might be high.
No. The diaphragm on the pressure gauge is leaking, and the gauge will soon be inoperative. Have the extinguisher serviced and repaired.
In a 5 kg DCP cartridge type extinguisher .the co2 cartridge pressure becomes 7 kg/cm2.
I have read it some where that the inside pressure of Co2 in fire extinguisher is 55 to 58 kg/cm2 at 21 deg C. However the pressure varies as per the ambient temperature.
Many pressurized water fire extinguishers are charged with air at 100 psi.
Yes, an automotive fire extinguisher needs to be recharged whenever you have used it or whenever the pressure gauge falls outside of the green range.
A fire extinguisher is meant to extinguish a fire, or at least a portion of the fire within the fire extinguisher's capacity.
how does a fire extinguisher work
A Class C fire extinguisher.

You would not want to use a pressure water extinguisher on any electrical fire due to the possibility of electricity being conducted through the water and injuring someone. A CO2, dry chemical or "clean agent" (e.g., "Halogenated") extinguisher would be a better choice for an electrical fire, knowing that dry chemical powder will make quite a mess.
We are use the co2 as fire extinguisher
