An assistant that works to protect us: the HA hazardous areas control

The intensity of industrial work poses constant risks for us.

But instead of deterring us, this only challenges us to look for more complete solutions and comprehensive responses to the threats and demands that arise around us.

That’s why, in this post, we would like to talk to you about one of the most important developments that is now being applied in several industries and manufacturing centres: the hazardous areas control.

We must conceive this tool as an assistant that works to protect us from some of the great risks we face as industrial operators. We refer to this system as an “assistant”, because it’s a technology capable of helping us even when we are unable to react appropriately, ourselves.


Hazardous area control (HA) helps us prevent the falling of people to pits or conveyor belts. It also avoids accidents in presses, crushers and compactors and allows perimetral detections in pits – all of them, risks which probably sound very familiar if you work in the recycling sector and, more specifically, in paper and cardboard recuperators, but also in other sectors such as forestry, agriculture and the like.


The core of this system consists on having operators carry electronic key tags and installing detector antennas in all machines – and their respective conveyor belts – with adjustable ranges between 1 and 5 meters. When the person who carries a tag falls on a belt, either as a result of an accident, after having been hit or having fainted, the machine automatically detects the proximity of the device and stops its operation, this preventing a very serious accident.


It is also an easy-to-deploy system – all you need is a personal key ring, detector antennas for the machines, a test-tag, a control box and a key ring antenna. This is how Claitec has already installed this solution in more than 100 recovery plants, and we continue to receive numerous queries about this new system.

In addition, the system stands out for its durability and robustness. It’s not affected by interferences between antennas and metal structures. The detection of the key ring is achieved in any position even when the material is being covered.
