In Kingman, Arizona, a critical incident unfolded during a propane transfer operation on a hot summer day. As propane was being transferred from a railroad car to a storage tank, a fire broke out unexpectedly. The firefighters on the scene quickly responded to the flames, attempting to contain the situation. However, the intense heat caused the propane to pressurize, leading to a boiling liquid expanding vapor explosion (BLEVE). This catastrophic event sent fireballs into the air and devastated the surrounding area, including the presence of firefighters engaged in controlling the blaze. Unfortunately, eleven firefighters lost their lives in this tragic explosion, marking a significant moment in firefighting history.The BLEVE, more commonly associated with industrial accidents involving flammable liquids and pressurized vessels, underscores the critical need for rigorous safety protocols when handling hazardous materials. In Kingman, the aftermath of the explosion prompted a reevaluation of safety measures in propane handling not only in Arizona but across the United States. Investigations revealed that the explosion's intensity resulted from the ignition of the flammable vapor released during the incident, indicating the dire ramifications of inadequate safety practices in volatile environments.
