Blind Flange Lockout

Best practice lockout solution
for pipeline maintenance

  • During pipeline maintenance, closed valves upstream could fail or residual material in the line may not be fully drained. These create potential exposure to downstream workers to chemicals, flammable gasses, oil, steam and other risks.
  • Use of a blind on a flange pipe is required by OSHA and provides a physical barrier against the unintentional release of energy.
  • The new blind flange lockout device provides the best practice solution to improve compliance and control of potential hazards. It ensures the blind will not unintentionally be removed until all work is complete and all personal safety locks are removed.

Blind Flange Lockout

An effective, locked out, physical barrier that helps prevent the removal of the blind until all workers have completed maintenance and remove their personal safety padlock.
