Rethink Emergency Stop with Safe-E-Stop

A wireless emergency stop used in conjunction with a hard-wired E-stop is an invaluable safety system. Companies that experience an accident are faced with a myriad of direct and indirect costs. And while the direct costs can be tracked, the indirect ones are often hidden and have a longer-term impact. This includes decreased employee confidence, time spent on ongoing investigations, providing additional employee training and support. As a result, employers are constantly looking to enhance their existing safety systems and processes with the goal of avoiding these situations entirely.  

Whether it is a localized worker dedicated to a machine, process or zone or a roaming worker responsible for multiple machines or locations within an area, there is no question that the combination of a hard-wired E-Stop with a wireless emergency stop will help prevent accidents and/or minimize scrap.

Hard-Wired E-Stop Plus Wireless Emergency Stop

There are four typical “steps” that a worker will pass through when a hard-wired E-Stop is in use and an emergency arises.

  • The worker recognizes that an emergency is happening. 
  • He/she locates the nearest E-Stop. 
  • Moves toward the E-Stop.
  • Presses the E-Stop.

Any delay in these actions increases the risk to workers and the amount of scrap material and waste. In addition, workers may have to move toward the danger zone to reach the E-stop.

The “steps” are reduced when a wireless emergency stop system is implemented with a hard-wired E-Stop. In the case of an emergency,

  • The worker recognizes that an emergency is happening.
  • He/she pushes the wireless emergency stop (Safe-E-Stop) that is clipped to their belt or vest. 

The rapid response and convenience enabled by the wireless emergency stop closes the time gap between the awareness of an emergency and the response. It provides another layer of critical protection to employees and productivity.  

Safe-E-Stop Overview

Safe-E-Stop is a Personal Safety Device (PSD) that is clipped to the vest or worn on the waist belt of workers giving them immediate, wireless access to conduct an emergency stop right from the worker location. Safe-E-Stop offers a SIL 3 safety rating and is certified by TÜV Nord to this standard. The PSD is a mobile extension of the machine’s hard-wired E-Stop.

Each Safe-E-Stop system comes with a Machine Safety Device (MSD) that is easily wired in series with the existing E-Stop system. The MSD can communicate with five PSDs at one time and has an operating range up to 100 meters (320 feet). PSD batteries last up to 14 hours and the system comes equipped with a battery charger so that the system can remain in use across multiple shifts.

Safe-E-Stop was designed to reduce the number of accidents in the workplace and works with existing safety systems to strengthen safety systems. Cattron has implemented Safe-E-Stop across a variety of applications in the material handling industry. Contact us at Request.NA@cattron.com to learn more.
