Is it true that a vapor cloud explosion could break windows up to 0.2 km away from an LPG tank?

• A. True
• B. False
• C. Depends on the tank size
• D. Only in enclosed spaces

Answer: (A)

The assertion that a vapor cloud explosion could break windows up to 0.2 km away from an LPG tank is indeed true. A vapor cloud explosion involves the rapid expansion and combustion of gas that has accumulated in the air, often resulting from a leak of a volatile substance such as liquefied petroleum gas (LPG). These explosions can generate intense shock waves. The energy released can be significant enough to produce strong pressure waves that travel considerable distances. Studies and historical incident analyses indicate that windows can be shattered by the powerful shock waves generated by such explosions at distances up to 0.2 kilometers or more, particularly under favorable atmospheric and environmental conditions. The other options do not hold up under scrutiny; for example, while the size of the tank may influence the scale of an explosion, it's established that vapor cloud explosions can produce significant pressure effects at considerable distances, making it plausible for windows to break even outside of a direct proximity to the tank. Similarly, the effects of pressure waves are not restricted solely to enclosed spaces, as overpressure can propagate through open areas as well.
