Trip device - Merits and Demerits

Trip device operate on the principle of sensing the presence of the operator and stop the machine. They involve use of sensory devices such as pressure mats, trip bars and photoelectric devices that when activated stops the machine. Hence they do not provide physical barrier between the operator and the dangerous parts of machine.



Merits

Merits of trip devices are they operate through sensors – it won’t be easily possible to defeat its intended purpose by a less skilled worker.


De-Merits

Main limitations / De-merits of trip devices are – They don’t provide physical barrier to prevent access; can be over-ridden / avoided (e.g. using platforms to span a pressure mat); May not operate fast enough to prevent harm. At time, may be over sensitive resulting in frequent trips and production delays. So, Management / Operators will be willing / encouraged to bypass or disable them. In addition, frequent trips may also result in operator stress.
