The alcohol reservoir on the crane's air brake system is getting a bad rap. Some well-meaning operators walk around the vehicle before the day's run. While in a hurry doing the checks and services, they open the petcock for the alcohol reservoir, because they think it's an air tank for the air brake system. So, the alcohol is drained out of the reservoir. But the reservoir is supposed to be filled year-round.

* Water expands when it turns to ice. That kind of pressure will burst most anything. You can lose your brakes and control of the vehicle.
