Risk Matrix

Certain construction projects are carried out in an unfavorable natural environment. They are exposed to special situations or factors that require a differential prevention planning, adapted to their characteristics. This is the case of maritime works in open waters, where the influence of climate factors such as tides, wind and swell may cause extraordinary professional risks that need a prevention system particularly adapted to that environment.

In order to suppress these risk factors, emerges the design of a risk matrix, capable of applying the measures of professional risk prevention defined in the safety plan, by means of a computerized system that measures the changing climate conditions, which may influence the safety of the employees working on a construction site with these features. It is done in a systematic way, using the direct data analysis or a regularly updated statistics as main data source.

It has also been foreseen the incorporation of specific data reception systems, as well as individual and collective protections that interact with the matrix depending on the risk at all times.

PREVITALIA participated together with FCC and the University of Oviedo in the development of this alert, protection and prevention system, especially developed for the harbor works.

The risk matrix is completed with individual and collective protections especially designed for their installation and use on the working platforms arranged on the formwork trolleys of maritime dikes. It is about a set of various elements bound between them that we call intelligent life line. Once more the environment and the location of the formwork trolleys during the dike conformation advise that the protections, either individual or collective, have automated systems in order to inform the worker about the obligation of using them, while alerting about their lack of use.

The invented device contributes to reinforce the obligatory nature of the harness use during the railing formwork on those maritime dikes, in order to prevent falling at sea. When an operator is located on the working platform, various warning signals are shot, perceivable on a distance. They facilitate a permanent supervision of the use or lack of use of the installed protection, making possible corrective actions regarding possible unsafe acts. These signals are acoustic and luminous type. The first one warns about the presence of an operator on the working platform and it would be activated by a detection device.

This sign remains connected until the life line is being used. That would be the moment when the second, luminous sign is activated, warning this time about the correct use of the protection. This sign remains visible from all the observation points, both from the dike itself and from the working camp.
