Acetylene is an unstable compound and should not be compressed _________ psi when in free state?

• A. 25
• B. 50
• C. 15
• D. 30

Answer: (C)

Acetylene is indeed an unstable compound, particularly under pressure. When compressed, its tendency to decompose increases, which can lead to dangerous reactions. The correct answer indicates that acetylene should not be compressed beyond 15 psi when in its free state. This limit is established to ensure safety and prevent the risk of explosive reactions that can occur at higher pressures due to the instability of acetylene. At pressures exceeding this threshold, the risk of third-party detonation or hazardous decomposition significantly escalates, making it crucial to adhere to these guidelines in pipe fitting and gas handling practices. Therefore, understanding the safe handling limit of acetylene is essential for anyone working with this gas in piping systems.
