If a product has a vapor density greater than 1, what will it do?

When a product has a vapor density greater than 1, this means that it is heavier than air. Because of this characteristic, the vapor will tend to sink rather than rise or disperse into the atmosphere. In practical terms, these heavier vapors can accumulate in low-lying areas, posing increased risks in confined spaces where they can displace oxygen.

This understanding of vapor densities is crucial in fire behavior, as the presence of such vapors can affect fire dynamics and the behavior of smoke and other byproducts of combustion. Products with a vapor density less than 1 would typically rise, which is not the case here. Understanding these properties helps firefighters and safety personnel make informed decisions about ventilation and escape routes during hazardous situations.
