If the vapor density of a hazardous gas is 1.15, where is the gas most likely to be found in a confined space?

A vapor density of 1.15 indicates that the gas is heavier than air, which has a vapor density of approximately 1.0. In a confined space, gases that are heavier than air will tend to accumulate closer to the ground, as they are unable to rise and disperse like lighter gases. Consequently, hazardous gases with a vapor density greater than 1.0 can create dangerous conditions by pooling in low areas, posing risks such as toxic exposure or suffocation.

This behavior is essential for personnel working in confined spaces to understand, as it informs proper ventilation strategies and safety precautions. Recognizing where such gases are likely to collect can help in preventing accidents and ensuring a safer working environment.
