What type of hazard are striking injuries that are the result of a BLEVE?

• A. Thermal
• B. Etiological
• C. Mechanical
• D. Chemical

Answer: (C)

Striking injuries resulting from a Boiling Liquid Expanding Vapor Explosion (BLEVE) are classified as mechanical hazards. BLEVEs occur when a vessel containing a pressurized liquid fails and the liquid rapidly turns into gas, causing a violent explosion that can project debris and shrapnel over considerable distances. These striking injuries are categorized as mechanical because they are directly related to the physical impact from the explosion and the resultant force of flying objects.

In the context of hazards, thermal hazards would pertain to exposure to high temperatures or flames, which are not the primary concern in this scenario. Etiological hazards involve biological agents that can cause disease, and chemical hazards refer to harmful substances that can cause reactions or toxic effects. While a BLEVE can involve thermal and chemical components, the immediate injuries from such an event categorize striking injuries as mechanical in nature due to the physical impact involved.
