Proper winterization of plant equipment – a message from the US Chemical Safety Board

 

At a refinery near Dumas, Texas, in February 2007, a water-containing pipe froze and cracked, releasing high-pressure liquid propane; the resulting fire burned three workers and caused more than $50 million in property damage. In January 2001, two workers burned to death at a large Indiana steel mill after they were sprayed with flammable gas condensate, which ignited. The accident occurred after ice had cracked and damaged a valve in the mill’s coke oven gas distribution system. 

 

The US Chemical Safety Board just issued a video on the need to properly winterize pipes and connections to prevent major chemical accidents.
