Carbon dioxide (CO2) is added to soft drinks during the bottling process to give the drink its fizz. While the soft drink containers are being filled during the bottling process, large volumes of CO2 are emitted from the fillers into the filler room atmosphere. If the filling rooms and the work areas are not adequately ventilated, CO2 can accumulate in the indoor air.
CO2 is a colorless, odorless, tasteless gas that poses a potential risk to human health in high concentrations. CO2 level should be monitored to avoid CO2 accumulation.
