In the blowdown process, what is the last step to be completed?

• A. Close outside (slow) valve
• B. Close inside (quick) valve
• C. Open outside (slow) valve
• D. Check for leaks

Answer: (B)

In the blowdown process, the last step to be completed is to close the inside (quick) valve. This is an important step because the inside valve is typically the first point of control for the flow of water or steam from the system that is being blown down. By closing the inside valve last, the operator ensures that any residual pressure or potential contaminants are fully expelled from the system before sealing it off. This sequence helps in preventing any potential backflow or contamination into the system, as it allows the process to discharge any unwanted substances completely prior to closing it off. Closing the inside valve too early in the process could trap contaminants and water in the system, which defeats the purpose of the blowdown. Therefore, completing the process by closing the inside valve ensures that the procedure is executed safely and effectively.
