Cartridges for mobile fire extinguishers
The second type of carbon dioxide cartridges are the ones in red. These are found on the outside of mobile fire extinguishers that are wheeled. When a fire occurs, the cartridges are hand turned to release the carbon dioxide propellant into the mobile fire extinguisher.
Due to the size of mobile fire extinguishers, these cartridges are larger and usually weigh at least 1 KG.
