5 Reasons to Protect Your Workers with Trapped Key Interlocks

June 15, 2017


Trapped key interlocks have been used in machine guarding applications, protecting workers in the US, since 1932.  The process of eliminating human error using trapped key interlock safety systems has prevented injury and death for countless workers.


Five key reasons to implement a trapped key interlock solution are:


  1. Fulfills ANSI Z244.1 requirements for machine guarding

  2. Delivers an enhanced level of protection vs. LOTO

  3. Removes the dangers of short cuts and mistakes

  4. Withstands harsh environments for decades of protection with a robust design

  5. Ensures no worker left behind in full body access areas with the use of a personnel key
