What is the purpose of purging a propane tank?

• A. To remove excess liquid propane
• B. To clear out contaminated air or trapped air
• C. To increase the overall tank pressure
• D. To test for leaks

Answer: (B)

The primary purpose of purging a propane tank is to clear out contaminated air or trapped air. Purging involves removing air and moisture from the tank to prevent issues that can arise from the presence of air, such as contamination or improper combustion when the propane is used. When a tank is purged, it ensures that only propane, which is more efficient and safe, occupies the tank, allowing it to operate effectively. The removal of air also helps in maintaining the correct pressure within the tank and prevents any potential explosion hazards associated with the flammable components of air mixing with propane. This step is crucial when newly filling a tank to ensure that it operates safely and efficiently from the moment it is put into service.
