An outage is defined as _________.

An outage is defined as the process of liquid expansion as it becomes warm. Outage is an important concept to understand for CDL drivers because it can affect the safety and performance of their vehicles. When a liquid expands, it can increase the pressure inside a tank. If the pressure is too high, it can cause the tank to rupture or explode. CDL drivers can prevent outage by monitoring the temperature of their liquids and taking steps to cool them down if they become too warm. They can also avoid outage by filling their tanks only to the manufacturer's recommended level.
