Posted By Colin Reeves Ashley An odd comment "CO2 is definitely a No, No. This would be a very dangerous system and would have to have so many safety measures built in it would become un-useable." If this was the case 90% of the worlds ships would not be at sea! CO2 is the norm, with a secondary system (generally required to have 2 nowadays) being hi-fog in most cases. Colin

Posted By Ashley Wood Colin, you are correct about ships. IMO (International maritime organisation) and SOLAS require these systems to be manually activated from a safe position and any one entering the risk space has to wear breathing apparatus (after a fire). These spaces are also viewed by CCTV. Also, there have been several deaths at sea due to asphyxiation caused by CO2! Hi-Fog (High pressure water mist system manufactured by Marioff Oy in Finland)has been installed in hundreds of ships to protect engine rooms, generators, oil purifiers etc and they are often used as the primary system these days. These systems also protect accommodation spaces unlike CO2. To make a CO2 system safe for a land based risk would require a mechanical lock off, an electrical isolator, a discharge diverter valve. You then have to allow for cold shock to electrical circuit boards in the IT Kit. You would need to install CO2 alarms in the area and in the storage area. Then you have to get rid of the gas after discharge and this would have to be at high level so you have to install an extract chimney. Do I need to go on!
