Pressure Wave generated by a 1-ton Cl2 cylinder catastrophically failing (WCS for Cl2 1-ton cylinder inside a Cl2 building)

So I asked Google Gemni + to calculate the pressure wave in a room that is 40′ X 40′ X 20′ tall with the catastrophic failure of a 1-ton chlorine cylinder. In a 32,000 ft³ room, we must determine the volume of gas released during the “instantaneous flash” and the resulting internal static overpressure.
