What must be removed from cylinders immediately after hydrostatic testing?

• A. All traces of oil
• B. All traces of water
• C. All labels
• D. All gas

Answer: (B)

After hydrostatic testing, it is essential to remove all traces of water from cylinders. The testing process involves filling the cylinder with water to check for leaks and ensure the integrity of the container under pressure. If water is left inside, it can lead to internal corrosion, degrade the quality of the cylinder, and ultimately compromise safety and effectiveness when the cylinder is reused. Removing water is a critical safety precaution to maintain the integrity of the fire extinguisher or gas cylinder, thereby ensuring readiness for future use. This practice helps prevent corrosion, which is important for the long-term durability of the cylinder and the safety of those who rely on it during emergencies.
