Safety
James R. Risko
Cold traps — steam traps that no longer drain condensate — are often ignored in lieu of less-critical leaking traps, until a catastrophic event, such as a plant shutdown or personal injury, occurs. Use historical data to accurately estimate the annual cost of these cold traps to justify their swift repair.

CEP: Editorial - The Invention that Wasn't

November
2012
Editorial
Cynthia F. Mascone
On the first day of our visit to Walt Disney World, my then-seven-year-old son got lost in the Magic Kingdom. Luckily, he was somewhere on Tom Sawyer Island, so our search area was limited. On the second day, he wandered off in the Honey, I Shrunk the Kids attraction (also an enclosed space, thankfully). Those experiences gave me an idea for what I called Kid LoJack — a biocompatible microchip that parents could inject under a baby’s skin, and later activate to locate the child if he or she got lost or kidnapped (or stayed out past curfew). I’ve often wondered — civil liberties issues aside — whether I could have patented such a device.

CEP: Spotlight on Safety - LOPA — A Valuable Risk-Reduction Tool

November
2012
Spotlight on Safety
John F. Murphy, P.E.
Layer of protection analysis (LOPA) is a simplified process risk-assessment technique that uses order-of-magnitude estimates for initiating events, consequence severity, and likelihood of failure of independent protection layers (IPLs) to approximate the risk of a scenario. It is generally used after a process hazard analysis (PHA) team has identified a hazard scenario that requires further analysis to ensure the adequacy of the safeguards that exist or are being proposed.
