Smart Emergency Stop

Prevent accidents with a more secure emergency stop mechanism

Switches providing secure stopping performance in case of an emergency

Emergency stop switch equipped in location not reachable by workers

Numerous measures have been developed to prevent industrial accidents in a wide variety of manufacturing sites. Although these include the proactive measures taken at food processing plants, there are still accidents involving workers having a body part or clothing caught up in machinery when equipment is suddenly operated by another person without noticing that maintenance or cleaning work is being performed, especially in the case of large processing equipment where it is not possible to have a sweeping view of the entire equipment. At some production sites there have been cases in which the worker realized that the machine was starting to operate and hurriedly tried to stop operation but the emergency stop switch was located too far away, preventing the worker from being able to press the switch. Inability to stop machine operation in an emergency is a huge problem. There is also the related problem of a worker slipping during normal operation and having a body part or clothing caught up in machinery, resulting in a failure to press an emergency stop switch. Finding a way to eliminate such risks certainly poses a great challenge to processing equipment designers.


Provide workers with a mobile switch allowing them to stop machine operation at any time

In order to solve this type of equipment safety problem, IDEC recommends operators carry our HE2G Grip Switches equipped with an emergency stop pushbutton switch as a risk-reducing solution. As the degree of danger when using large processing equipment increases when workers are positioned at some distance from the operating panel, use of grip switches with an emergency stop pushbutton switch that can be constantly held by a worker when performing cleaning and similar work enables an emergency stop to be performed from such positions. Now, workers in this food processing plant can work safely without fear of such physical dangers.

Taking into account the tendency of people not to act rationally during an emergency

There are also cases where a worker wants to move a rotary conveyor a little bit at a time to perform cleaning. The HE1G-L is equipped with a Three-Position Enabling Switch, making it perfect for such production lines. By lightly gripping the wearable grip switch, a worker can easily operate the equipment even in maintenance mode and stop operation just by removing his or her hand from the switch. The enabling switch cuts off the power circuit even if the switch is strongly gripped by a panicked worker due to a suddenly occurring emergency, providing the equipment with a secure emergency stop mechanism and increased safety. In this way, these enabling switches serve as a safety device that take into consideration the tendency for "humans to not act rationally in an emergency."
