Open doors caused dangerous icing?
A meatpacking warehouse in Oklahoma had poor control of its manual dock doors. Occasionally, doors were accidentally left slightly open (2-4 inches). Being a freezer dock kept at 20 degrees Fahrenheit, any outside air was warmer than the inside dock air. In the heat of a southern summer, temperatures outside commonly hit 100 degrees Fahrenheit, with humidity to match. This caused two main problems: fogging in the dock area that would create icing on the coils in the cooling towers and fogging that would hit the cold dock levelers and form a thin layer of ice, making loading a trailer dangerous.

Any open door with no trailer would have immediately prompted the system to send alerts to maintenance and management, preventing the situation from escalating to dangerous icing.
