Safety valves and vibration

A news article mentions that there is a dispute between BP and OSHA over spring loaded safety valves. the article mentions that "OSHA is concerned because improperly set valves can result in too much shaking, said Jordan Barab, deputy assistant secretary of labor for OSHA. That vibration could cause the valves -which regulate the opening and closing of pressure vessels - to break.BP believes the valves "comply with industry standards and do not constitute a safety hazard," said spokesman"
The article also mentions that the total cost of the 2005 BP Texas city refinery explosion is 3.5 billion dollars.
