These trapped key interlocks ensure energy isolation in LOTO procedures. Courtesy: KIRKEnhancing lockout tagout procedures with trapped key interlocks ensures energy isolation procedures cannot be circumvented. The trapped key interlocks can aid in isolating the energy source and the lock and tag can be applied to the interlock. The key is removed from the trapped key interlock and is with the person leading the lockout tagout procedure. The equipment cannot be re-energized until the uniquely coded key has been re-entered into the sequence after all workers are clear from the completed task.  A time delay unit can be added into the process to allow the hazardous energy to dissipate prior to allowing access.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
