What could be a potential consequence of not venting air from the system prior to a pressure test?

• A. Reduced test efficiency.
• B. Water can leak from the system.
• C. Risk of explosion if the line fails.
• D. Increased test duration.

Answer: (C)

Failing to vent air from the system prior to conducting a pressure test can lead to a dangerous situation where an explosion risk exists if the line were to fail. When air remains trapped in the system during a pressure test, it can compress and create an unsafe environment. If the pressure becomes too high, especially with air present, it could cause the line to rupture or fail, resulting in a sudden release of energy and potential projectiles, which can be considered an explosive reaction. Additionally, the presence of air can lead to erratic pressure readings, making it difficult to accurately assess the integrity of the piping system. Proper venting ensures that only the test medium (often water or another fluid) provides a consistent and reliable means of assessing how the system withstands the applied pressure. Therefore, the correct course of action includes venting air to prevent not only inefficiencies but more critically, hazardous conditions during the pressure testing process.
