MANY THANKS to my friend and NH3 PSM Guru Brian Chapin, Compliance Services Manager - RC&E for sharing this with his TAO Compliance Group. Hansen recently discovered that certain pressure relief valves sold to our customers for industrial use from February 16, 2011, to April 4, 2013, are more susceptible to internal corrosion when exposed to standing water inside the valve. Even though the risk is remote, the failure of a pressure release valve could conceivably result in serious personal injury and/or property damage. Consequently, Hansen has initiated a program to send replacement valves so that any valves currently at risk can be replaced promptly. Hansen has not received any reports to date of any valve failures that have resulted in personal injury or property damage, but Hansen is taking this action in the interest of safety and avoiding potential risks. We are therefore issuing this recall of all valves that may be potentially impacted.
