What happens to vapor with a density of less than 0.6 in a fire situation?

• A. It will settle on the floor
• B. It will rise to the ceiling and accumulate
• C. It will dissipate rapidly
• D. It will condense into liquid

Answer: (B)

In a fire situation, a vapor with a density of less than 0.6 is lighter than air. Because of this property, it tends to rise when released into the atmosphere. As it moves upwards, it can accumulate at higher levels, such as near the ceiling of a room. This behavior happens due to the buoyancy effect, where lighter substances rise compared to heavier ones. It is essential in fire safety and investigation to understand the behavior of vapors, as their accumulation can lead to hazardous conditions, such as increased flammability or explosive atmospheres. Recognizing that lighter-than-air vapors will ascend is critical in evaluating fire risks, ventilation needs, and proper safety measures in the event of a fire.
