What is a potential hazard of improperly stored CNG?

• A. Risk of combustion due to heat
• B. Risk of explosion due to high pressure
• C. Risk of contamination from water
• D. Risk of corrosion in storage tanks

Answer: (B)

Improperly stored Compressed Natural Gas (CNG) primarily poses a risk of explosion due to high pressure. CNG is stored at very high pressures—typically between 2,900 to 3,600 psi. If storage containers are not designed for these pressures or if there are any leaks or failures in the containment system, the gas can escape, accumulate, and create an explosive atmosphere. Since CNG is lighter than air, it can disperse quickly in outdoor environments; however, in confined spaces, it can pose a significant explosion hazard if ignited. The integrity of storage systems is crucial; hence, proper storage procedures and equipment specifically designed for high pressure must be followed to mitigate these risks. Ensuring that both pressure ratings of storage containers and the maintenance of these systems meet regulatory standards is essential for safety.
