Case study: Second stage in the implementation of the Traffic Control System in GSK

As we saw in the first post pertaining to the GSK’s success story, the company prioritised the care and welfare of its employees by installing a Traffic Control System (TCS) in its plant’s production area. After verifying the success of the solution in the first phase, the company took another step towards industrial safety, incorporating Claitec’s Traffic Control System to its warehouse area.

The purpose of this solution is to adequately segregate pedestrians and forklifts, ensuring a safe work environment for both operators. Like many of Claitec’s solutions, the Traffic Control System is a passive approach that does not require the attention or operation of a person. It works by placing a TZ2-Tag device in the warehouse which, detects the presence of trucks in turn equipped with another activator. It also includes traffic lights, signage, safety gates and pedestrian railings.


During the first phase of the TCS implementation in the production area we encountered a unique problem – the corridors were very narrow. This made it difficult to separate pedestrian crossings and forklift trucks properly. There were also more forklifts in the warehouse and more free space, causing them to travel at faster speeds. If we add the fact that in the warehouse there are few pedestrians and that the forklift operators work with a lower degree of alertness, we have before us a place with greater risk of accidents.

The objective of the second phase was to adequately segregate pedestrian and forklift traffic. This required a combination of technology for adequate signalling, detectors, as well as doors that ensure the safety of operators by preventing their passage to risk areas. In this video you can see how the TCS solution was installed to allow us to successfully meet the objectives of this second phase and to provide a more efficient and safe work for GSK’s warehouse operators.


As seen in the video, the solution includes detectors that identify the presence of a forklift in the area. Signalling devices – two traffic lights – alert pedestrians to the presence of a nearby forklift. But the great novelty of the solution lies in the gates as these close automatically in the presence of the forklift, preventing any operator on foot from entering the area. When the area is free of forklifts, they open again, allowing the normal passage of any pedestrian with or without carts.

The gate has the added advantage of a motorised opening and closing system – extremely useful for operators with occupied hands, particularly if pushing a cart. Besides the obvious safety it provides pedestrians, these gates help forklift drivers work more safely and efficiently, with the assurance that there will be no pedestrians in their transit zones. They can even “forget” about potentially crossing paths with pedestrians in poor visibility areas.


Worthy of mention also is the fact that the traffic lights indicate green or red according to the situation, providing extra security for all those involved.


GSK took a new step towards providing greater safety to its operators. After the first two phases, in which the company secured the safety in the production plant and the warehouse, GSK plans to implement a third stage, installing the solution in its medicine plant. This would complete the implementation of Claitec’s pedestrian warning and traffic control system of its Aranda de Duero plant.
