Safety valves and their importance

A news article (a little old) mentions about an accident in an alumina digestor plant where 2 persons were killed apparently when a safety valve "exploded" and spread chemical around . Safety valves will do their job of relieving pressure if they are properly maintained and erected. Many times, plant and mechanical personnel do not bother to observe whether the safety valve downtake pipe (if open to atmosphere) is located away from personnel. The testing of safety valves is very important. All data regarding safety valves must be preserved carefully as part of your asset integrity program.
