Which statement is true regarding BLEVE susceptibility of stored gas cylinders?

The correct statement regarding BLEVE (Boiling Liquid Expanding Vapor Explosion) susceptibility of stored gas cylinders is that only certain types are susceptible. This understanding hinges on the characteristics of the gases contained in the cylinders and the presence of specific conditions that lead to a BLEVE.

Certain gases, particularly those that are stored under pressure and have low boiling points, are more prone to BLEVE events. For instance, flammable gases like propane or butane can pose significant risks if exposed to heat, as they may rapidly expand and cause a violent explosion if the cylinder fails. Conversely, other gases may not have the same risk profile due to their physical properties or because they are stored in a manner that mitigates this risk.

Understanding the susceptibility is crucial for fire safety protocols, as it influences how firefighters approach incidents involving these cylinders. Proper identification allows for tailored strategies to manage and contain potential BLEVE scenarios, focusing on the most hazardous cylinders instead of treating all cylinders as equally dangerous.

The other options do not accurately capture the nuanced risks associated with gas cylinders. Not all cylinders are susceptible, as many types of gases are stored in conditions that make them far less likely to undergo a BLEVE. Similarly, the idea that only empty cylinders are susceptible is misleading,
