What is the purpose of providing a means of venting vapors trapped in sloped tanks?

• A. To allow for easier inspection of tanks
• B. To facilitate tank tightness testing at a later date
• C. To prevent overfilling of tanks
• D. To improve the flow of product

Answer: (B)

The purpose of providing a means of venting vapors trapped in sloped tanks is primarily to allow for proper functioning and safety of the tank system. When vapors accumulate in sloped tanks, it can lead to pressure build-up that might cause operational issues or hazards. By venting, operators can ensure that the internal pressure is regulated, allowing for accurate measurements and assessment of the tank's integrity, which is critical for tightness testing in the future. Venting helps maintain the right conditions within the tank, which makes it possible to accurately check whether the tank is sealed properly and that there are no leaks. This proactive measure is necessary for compliance with environmental regulations, as well as for preventing potential safety hazards that could arise from vapor accumulation.
