For the last 5 years, I've been using a CIP re-circulation system, which has tanks equipped with 15psi pressure valve(s) and re-circulation under 10psi. After filling the FV (fermentation vessel) with the correct amount of hot water and caustic solution, I'd run the CIP for 15-20 minutes with all the vents closed. Does this lack of ventilation during the process put the tanks in jeopardy of exploding and/or imploding?

When you empty a tank, there is typically a bit of carbon dioxide (CO2) remaining. If you run the CIP using caustic without venting, you take the chance of the caustic (solution) reacting with the carbon dioxide, creating a vacuum inside the tank and possibly causing it to collapse. More importantly, if no anti-vac valve exists on your closed tank, the risk of implosion of that tank is significantly increased.
