Process Safety

Controlling the sequence of events in which process activities are conducted, has been achieved historically using a Permit to Work (PtW), accompanied by documented instructions. However, this system is hostage to ‘human factor’ distractions. Failure to interpret instructions correctly or ignorance of the system, can all lead the operator to make errors, which can manifest themselves in industrial accidents of varying magnitudes.

Trapped Key Interlocks are simple, mechanical devices, which can be customized to implement a safe sequence of operation in any process activity.  Smith Flow Control’s Process Management Systems provide effective protection to clients’ investments in plant and equipment as well as improving employee safety and reducing the risk of damage to the environment.
