preparing for cold weather at chemical and other process facilities. 

As outdoor air temperatures drop, it is important for chemical and other facilities to be prepared for the unique safety challenges posed by cold weather, such as the hazards of water freezing and expanding, which can damage equipment or cause instrumentation to fail. When the temperature drops, the freezing process begins, and materials expand. This can crack or break pipes and rupture or damage process equipment. This damaged equipment may not become evident until the temperature rises, the ice thaws, and a leak develops. More subtle hazards may also exist, such as the formation of a hydrate, where water chemically combines with a compound, forming a solid that can also block process piping. This can happen even above freezing temperatures.
