Manu_2000 Posted May 13, 2019 Report Share Posted May 13, 2019 Is a Co2 extinguisher safe for a confined space such as a subway station? We're planning to put cartridge 9l foam extinguishers + 2kg Co2? Are These when discharges dangerous enough to result in asphyxiation? Another alternative we didn't like was dry powder, it's very messy! You may reccomemd me water mist, but fire ratings are EXTREMELY LOW! what about inside the trains? What should I install?

AnthonyB Posted May 14, 2019 Report Share Posted May 14, 2019 Absolutely safe, there is no way you are going to get a dangerous concentration, you only get a cubic area of gas sufficient to fill 2 bathtubs from 2kg of CO2, as long as your volumetric area is at least 10 times that (which an underground station certainly is) you are fine Quote Link to comment Share on other sites More sharing options...
AnthonyB Posted May 14, 2019 Report Share Posted May 14, 2019 London Underground uses 9 litre spray foam and 2kg CO2 at fire points as an example Quote Link to comment Share on other sites More sharing options...
