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

When a product has a vapor density of less than 1, it indicates that the vapor is lighter than air. As a result, this lighter vapor will tend to rise into the atmosphere. This behavior is due to the difference in density compared to air, and it is essential in understanding the behavior of gases and vapors during fire scenarios.

For example, gases with a vapor density less than 1 are likely to disperse upward, which can affect how they spread in the environment and influence the effectiveness of ventilation strategies during firefighting operations. Recognizing that lighter vapors rise is crucial for anticipating fire behavior and potential hazards associated with vapors in different conditions.
