Safety and Productivity
• Developed Safety Culture - Without the buy-in of everyone from upper management down, implementation of effective safety systems is difficult.
• Formalized Risk Management processes - Establish a formalized risk management strategy to identify, prioritize and mitigate risks.
• Investments in technologies that improve both safety and productivity – taking advantage of available diagnostics, and the use of information technologies to provide information to the broader manufacturing environment.

Benefits of a ContemporarySafety Solution
• Reduced time to design, program, install and start-up
• Reduced space requirements – floor space and panel space
• Wiring reduction, wiring simplification and network integration
• Improved operator diagnostics and increased opportunities for alternative methods to Lock-Out-Tag-Out for routine tasks (where applicable)
• Reduced maintenance MTTR, reduced downtime
• Accommodates future process or safety changes
• Accommodates tasks and processes and does not require workers to “work around” the safety system,…reducing risk
