Each component of the system, whatever it is (tank, pump, valve, pipe or fitting) must be in harmony with the surroundings of the function for which it was designed. For operation safety and protection of the environment and people, nothing can be left to chance, the slightest possibility of a malfunction or accident, due to inexperience, negligence, external events, must absolutely be avoided. In that context, avoiding thinking 'so far it has never happened', a 'not minimal' design with an adequate margin of safety, will give the certainty of the tranquility of the proper functioning.
It is easily understood how automated systems may have influenced the safety, in the last thirty years, if we think on the car airbags, the home kitchens -- with the interruption of gas if the flame goes out -- the progressive deformation of cars, the fire alarms, we realize that we can not do without certain 'lifesaver' applications. In this context, considering also the saving that is obtained, in terms of production speed and saving of time, to mention just two factors, each component can be equipped with accessories and devices necessary to reach the maximum efficiency, avoiding wastage and coming to the certainty of the required quality, without waste or additional controls.
