As a dissolved gas, if the solution is not kept under pressure, or if there is space above the solution, the Chlorine Dioxide gas will come out of solution. If the solution is in an enclosed space, such as a tank or chemical tote, the gas will accumulate in the space above the solution. At a concentration as low as 3,000 mg/l, this accumulation of gas is right on the edge of the “Safe Zone” at 77 degrees F as shown by the Fig. 1 chart. If the temperature of solution rises above this threshold, the potential for explosion increases significantly. However, at 700 mg/l, the temperature of solution must be much greater than 86 degrees F to venture into an area of caution.
